Siddharth Balyan 4bdd64b334 The free tier is created in one place, at boot, only behind HERMES_GUEST_ONBOARDING=1 (NS-847) (#107697)
* fix(auth): close the free tier's gaps against the gateway's welcome-tier contract

The inference gateway's welcome tier (NousResearch/api DOCS/anon-tier/plan.md) serves an
anonymous account exactly one model on its own host, refuses everything else with a structured
429, cross-refuses a request on the wrong host with a 400 (403 while the tier is dark), and
tells a signed-in account that still asks for `nous/welcome` what to switch to in an
`x-nous-model-switch` header. Four client-side gaps against that contract:

- Auxiliary calls were refused on every session. The auxiliary client asked the welcome host
  for the Portal's recommended compaction/vision model, a guaranteed 429 `model_not_free`
  before each fallback. On the welcome host it now uses `nous/welcome` (its backing model
  covers auxiliary work) and skips Nous for vision, which the welcome model does not take.

- The structured 429 body was never read. The classifier now parses `reason` /
  `retry_after` / `alternates` / `upgrade_url`: `model_not_free` and `feature_not_free` are
  non-retryable gates that fall back; `at_capacity`, `admission_closed` and `rate_limited`
  are rate limits that honour `retry_after` and never rotate the free tier's only credential.
  The wrong-host 400 and the dark-tier 403 are deterministic, so they abort this route and
  fall back instead of retrying or re-exchanging. The terminal paths say what happened and
  name the sign-in (`/login` in a chat, `hermes auth upgrade` in a terminal).

- The `x-nous-model-switch` header was ignored. The chat-completions transport records it
  beside the rate-limit and credits headers; the next call moves the session, and the config
  default when it still names `nous/welcome`, to the backing model the gateway named.

- A guest fell back to the paid host. With `inference_base_url` absent from the exchange or
  outside the host allowlist, routing defaulted to inference-api, where every request is a
  400. A guest now defaults to the welcome literal at the exchange, in the shared store's
  shape, and in effective routing.

* feat(auth): the free tier is set up on request; nous.guest_setup decides whether also on first use

A caller that names nous/welcome on a Nous route with no Nous identity in reach — the guided
setup's session (provider=nous, which skips the resolver's nothing-configured rung), the free-tier
picker row, a bare --provider nous pointed at it — is asking for the free tier. The OAuth runtime
rung now sets it up there instead of failing "not logged in", so the guided chat no longer races
the root profile's first-run mint.

nous.guest_setup is the policy seam: "auto" (default) keeps today's first-use setup wherever
nothing else is configured; "on-request" mints only when the free tier is asked for by name
(nous/welcome, /login, hermes auth upgrade, replacing a retired identity). Implicit callers —
the resolver's last rung, the first-run check, free_tier.status, the CLI's background setup, the
connector token path — still adopt what the shared store holds, so every profile follows the one
identity the guided setup created, but never create one on their own.

* feat(auth): the guided setup provisions the free tier explicitly; nous.guest_setup is auto | explicit

Two questions govern the free tier: may it exist (nous.guest) and who may CREATE the identity
(nous.guest_setup). "auto" (default) keeps today's first-use setup wherever nothing else is
configured. "explicit" means Hermes never creates one on its own: the only creator is the new
provision_free_tier() primitive, exposed as the free_tier.provision RPC, which the guided setup
on Hermes Desktop calls as its first step — on the root gateway, before the setup profile and
before the guided chat exists — so the identity lands in the root store every profile reads
through and is there before any session asks for nous/welcome. That closes the race against the
backend's own setup, and makes "only when the setup-bot flow is used" literally true.

The earlier "on-request" tier is replaced: it minted whenever any caller named nous/welcome
(the hermes model row, --provider nous), which treated a model name as intent and was broader
than the guided setup. Under "explicit" a nous/welcome request with no identity fails "not
logged in" as before the free tier existed, and /login or hermes auth upgrade report nothing to
sign in from. Implicit callers still adopt an identity the shared store holds, and a retired
credential is replaced (a continuation, not a creation).

* fix(auth): remove the nous.guest_setup knob; the free tier is created on first use

`nous.guest_setup: auto | explicit` decided who may CREATE the free-tier identity. Under its
default every line it added was inert (`may_mint` always true), nothing in tree set `explicit`,
unknown values read as `auto`, and under `explicit` a CLI-only install could never get an
identity, which contradicts the first-run contract (first command mints, then chats).

The mint race the knob accompanied is already benign: every caller takes the profile lock then
the shared-store lock, and the loser adopts what the winner wrote. What makes the guided setup
win deterministically is `provision_free_tier()` behind the `free_tier.provision` RPC, which
stays. `nous.guest` remains the only free-tier policy.

Removed: `guest_setup_policy()` and its constants, the `explicit=` / `may_mint=` threading through
`ensure_portal_identity` and `_reconcile_and_provision`, the flag at the three replacement call
sites (now no-ops), the config default, the docs section, and the four `guest_setup` test-config
entries. The three policy tests that hold regardless of the knob are kept under
`TestExplicitProvision`; the two that only tested the knob are deleted.

(cherry picked from commit d8a50526d93c374c0067dd935b5a65055e0af261)

* fix(gateway): a server-driven model switch off nous/welcome does not evict the cached agent

When a signed-in account still asks the paid host for `nous/welcome`, the inference gateway
serves the current backing model and names it in `x-nous-model-switch`. `apply_model_switch`
moves the live session to that model and moves `config.yaml`'s default off the alias in the
same step. The messaging gateway's fallback-eviction check compares the agent's model with the
config default and evicts on any mismatch that is not a /model override, so when the config
write did not land (unreadable config, lock) the cached agent was evicted once per turn, and
prompt caching with it.

`apply_model_switch` now stamps the alias it moved the session off on the agent, and
`_is_intentional_model_switch` treats "agent moved off the alias the config still carries" as
deliberate, beside the existing /model override case. The check takes the agent and the config
model instead of a bare model string; its one caller in `_run_agent_evict_on_fallback` passes them.

* fix(auth): the free tier outranks implicit host credentials in provider resolution

On a fresh install with a leftover ~/.aws profile, resolve_provider("auto")
reached the Bedrock rung before the free-tier rung, so the first turn ran on
Bedrock and failed 403 while the free tier was still being minted in the
background at agent setup (NS-829). Live on a Mac with ~/.aws present: 28 s,
three retries, no answer; the next process then switched to nous/welcome.

The free-tier rung now sits directly above the Bedrock chain: when nous.guest
is on, an existing free-tier identity answers, else a blocking mint runs, and
only then does the boto chain get a say. Everything above is unchanged and
still wins: CLI creds, config.yaml model.provider, env keys, the OpenRouter
pool, a logged-in active_provider. nous.guest: false skips the rung, and a
failed mint still falls through to Bedrock and the no-provider guidance.

Tests: six precedence cases (identity present, fresh mint, free tier off, env
key still wins, sign-in still wins, failed mint falls through). The opt-out
test now neutralizes the AWS chain like the precedence tests do; on a machine
with ~/.aws it was failing for the same reason as the bug.

Live after the fix, same Mac, AWS credentials visible, isolated shared store:
identity minted 2 s in, turn on model=nous/welcome provider=nous, answer in
11 s.

* fix(auth): review follow-ups for the free-tier rung (NS-829)

- tests/agent/test_bedrock_integration.py: the Bedrock auto-detect test switches
  the free tier off; its contract is the boto chain, and the free tier now
  sits above it.
- gateway/run_notifications.py: the free-tier startup line reads auth.json
  before consulting the resolver, so a gateway boot on a machine with AWS
  credentials never mints or refreshes over the network.
- hermes_cli/anon_auth.py: module docstring says where the free tier sits in
  the ladder instead of "the ladder is untouched".
- tests/hermes_cli/test_provider_precedence.py: two invariant tests instead of
  six (parametrized ladder cases; a failed mint that returns None or raises
  falls through to Bedrock).

scripts/run_tests.sh on the five affected files: 147 passed, 0 failed.

* feat(auth): HERMES_GUEST_ONBOARDING=1 is the one launch gate for the free tier; HERMES_FORCE_GUEST is gone

The free tier is pre-GA. Until GA it must not exist for anyone who did not
ask for it: no identity minted, no portal traffic, no free-tier copy on any
surface. One environment variable now decides that, and one function reads it.

`guest_enabled()` returns False unless `HERMES_GUEST_ONBOARDING` is exactly
"1"; only then does `nous.guest` (the user's off switch) get consulted. Every
free-tier site already funnels through `guest_enabled()`, so the gate closes
minting, routing, connector entitlement, status lines and the picker row in
one place. With the variable unset, `resolve_provider("auto")` on a fresh
install raises `no_provider_configured` exactly as upstream does.

`HERMES_FORCE_GUEST` and `force_guest_mode()` are removed. They inverted the
gate (forced the tier ON over `nous.guest: false`), their "new" value re-minted
identities as a side effect of provider resolution, and `_has_any_provider_
configured` read them ahead of every other check, making the CLI a second
reader of a flag that must have exactly one. `_forced_new_done` and the
`force` parameter of `_reconcile_and_provision` go with them.

Supersedes the dev lever introduced in fcf9d11679 (rung 1) and hardened in
b5c162c3ec. Ruling: NS-845 Q1.1 (recorded on NS-847).

Not a user preference: the variable is never written to config.yaml or .env
and never shown in setup. It is deleted at GA together with its comment in
anon_auth.py. This is a deliberate, temporary exception to the "no new
HERMES_* env vars for non-secret config" rule.

Tests: fixtures set the gate instead of deleting the old lever; one new
invariant (`test_launch_gate_off_means_no_free_tier_at_all`) proves that "",
"0", "true" and "new" all leave the tier off with zero portal calls, red on the
previous commit. The `HERMES_FORCE_GUEST=new` re-mint test is deleted with the
feature.

* feat(auth): the free-tier identity is created in one place, at boot; every other site is a read

Before this commit eight sites could create a Nous free-tier identity as a
side effect of something else: resolving a provider, the CLI's first-run
check, the CLI's session setup (in the background beside an own key), a
connector bearer read, the desktop polling `free_tier.status`, the sign-in
precondition, the desktop's `free_tier.provision`, and the dead-credential
re-mint. A poll could mint. Provider resolution could hit the network. Two
of them raced each other on a fresh install.

Now `hermes_cli/free_tier_bootstrap.py::run_bootstrap` is the only creator.
`hermes serve` runs it on a daemon thread from `_lifespan` beside the other
background boots; `cmd_chat` runs it synchronously before the first-run
guard. It inventories credentials first (`resolve_provider("auto",
skip_free_tier=True)`: what would carry inference if the free tier did not
exist), creates the identity only when `guest_enabled()`, resolves inference,
records a `SetupRecord` in process memory and broadcasts ONE `setup.ready`
event. It runs on every boot; only the mint is gated.

`ensure_portal_identity` now requires `explicit=True` and raises otherwise.
Its callers are the bootstrap, the desktop's `free_tier.provision` (the
explicit retry when the boot could not create the identity) and the two
dead-credential replacements (`auth_nous.resolve_nous_runtime_credentials`,
`managed_tool_gateway._replace_dead_guest_token`). The background thread
path and `provision_free_tier` are deleted with their last callers.

Reads that used to mint and now only read: `auth.py::resolve_provider`
rung 7 (an existing identity still outranks the Bedrock chain, NS-829
ordering kept), `main.py::_has_any_provider_configured`,
`cli_agent_setup_mixin._ensure_runtime_credentials`,
`managed_tool_gateway.read_nous_access_token` (no identity -> None),
`anon_sign_in.run_sign_in` (no identity -> Unavailable),
`methods_free_tier` `free_tier.status`.

`setup.status` answers from the record for the launch profile, blocking up
to 8 s while the bootstrap is in flight so a client's first poll lands after
the identity exists rather than racing it; a named profile, or a process
that never ran the bootstrap, keeps today's live probe. The record's fields
ride along additively (`ready`, `free_tier`, `other_providers`,
`inference_provider`).

Identity and inference are decoupled (NS-845 Q1.3): the mint sets
`active_provider="nous"` only when the inventory found nothing else usable
(`_mint_locked(carries_inference=)`); an adopted account always does. A token
refresh no longer re-elects the provider it refreshed
(`_save_provider_state_to_source` writes credentials, not the user's
choice) — that write was how an own-key install ended up on the free tier
after the first connector call.

Supersedes the mint sites in fcf9d11679, a42d0748fc (first-run check),
bbbaa8935a (CLI background setup), 0179efc989 (`free_tier.status` mint),
62ad1ff3ab / c63d2c935c / d8a50526d9 (the `nous.guest_setup` knob and
`provision_free_tier`), and a04b05260c (blocking mint in the resolver).
Ruling: NS-845 Q1.2 + Q1.3, recorded on NS-847.

Tests: `TestBootstrapIsTheOneCreator` (one mint per process; own key keeps
inference; reads never reach the portal; a refused mint is memoised),
`free_tier.status` fails loudly if it ever calls the creator, the resolver
stub fails loudly if resolution ever mints, `setup.status` reads the record,
`skip_free_tier` proves the inventory question. The three sign-in tests for
the deleted pre-mint collapse into one (`no identity -> Unavailable, zero
portal calls`). Live: real `_lifespan` boot with a fake portal, gate on and
off (/tmp/ns847-recon/evidence/e2e-rung5-c2-serve-boot.txt), and the CLI
matrix incl. an own-key cell (e2e-rung5-c2-bootstrap.txt), 20/20.

* fix(credits): the welcome host is free-tier evidence, so a free-tier identity never sees "run /topup"

A free-tier identity carries $0 by design, so the portal seed reports
`paid_access=False` for it. `is_free_tier_model` did not know the welcome
host, read that as a depleted account, and every free-tier turn ended with
the credits-depleted notice telling the user to top up an account they do
not have.

Rule (4) in `is_free_tier_model`: a `base_url` on the Nous welcome host
(`anon_auth.route_is_welcome_host`) is the free tier. The host is the
evidence, not the model name: the paid inference host can serve
`nous/welcome` to a named account and that account's depletion is real, so
`("nous/welcome", <inference host>)` stays False. Local data only, like the
three rules above it.

Restores the two contracts dropped by hermes-magic 674e11d1eaa (the
prototype line ran without unit tests): the welcome host is free without
any pricing evidence; the model name alone is not. The first is red without
this fix.

* fix(copy): free-tier text stops promising a connector transfer and never names the config key

Sign-in copy on every surface said "Sign in to keep your connectors" and
ended with "Your connectors are kept." The transfer registry that would
make that true is empty (NS-821): nothing carries over today. The copy now
says what signing in does give ("unlock more models and tools") and the
completion line names the account, not a transfer. The docs page loses the
"connectors carry over" paragraph for the same reason.

The picker's off-state line exposed `nous.guest: false` and the word
"guest"; user copy names the free tier only (R-USR-1).

The docs page gains the pre-rollout note: until GA nothing on it happens
without `HERMES_GUEST_ONBOARDING=1`. Its "first command mints" and
"replaced on next use" sentences now describe the boot bootstrap.

zh is a strict locale: the `freeTier` block was English placeholder text
copied from `en`; it is now Chinese. `connectorsKept` is renamed
`completedBody` since it no longer talks about connectors.

* feat(desktop): the free-tier launch flag is decided once in Electron and stamped onto every backend spawn

The Python backend reads `HERMES_GUEST_ONBOARDING` and treats exactly "1"
as on. Until now nothing in the desktop set it, so a packaged app could
never turn the free tier on, and a backend spawned by the app could
disagree with the app about whether the tier was live.

`electron/guest-onboarding.ts` owns the decision: `guestOnboardingEnabled`
is true when the launch env has `HERMES_GUEST_ONBOARDING=1` or argv has
`--guest-onboarding` (the packaged-app spelling). It is read ONCE at launch
into a module constant. `desktopBackendSpawnEnv` wraps every backend env
as the outermost call and writes the flag LAST, as "1" or an explicit "0",
so no earlier spread (`process.env`, `backend.env`) can resurrect a stray
value from the parent shell.

Stamped onto all three spawn sites: the primary `serve` spawn, the pooled
per-profile spawn, and the remote SSH `exec env ...` command (which gains
` HERMES_GUEST_ONBOARDING=1` only when on). The embedded terminal PTY and
the backend probes are not backend spawns and do not get it: a
`hermes --tui` typed in the pane must not mint.

The renderer learns the same fact read-only through the existing
`hermes:launch-flags` sync IPC (`guestOnboarding`) and preload
(`window.hermesDesktop.guestOnboardingEnabled`).

Ruling: NS-845 Q1.1 / Q2 (env var is the contract, `--guest-onboarding`
maps to it in main). Two invariant tests on the pure helpers: only "1" or
the argv flag enables; the spawn env carries "1"/"0" as the last word and
preserves every other key.

* feat(desktop): the renderer learns free-tier readiness from one `setup.ready` push, not a 60 s poll

The backend's boot bootstrap now announces `setup.ready` once, after it has
created (or refused) the free-tier identity and resolved the inference
route. The renderer used to discover both by polling `setup.status`,
`setup.runtime_check` and `free_tier.status` every 60 s from
`useStatusSnapshot`; a fresh install's chip, notice strip and onboarding
overlay could sit stale for up to a minute after boot, and three RPCs a
minute per window kept asking a question whose answer changes only at
boundaries the backend already announces.

`handleLifecycleEvent` routes `setup.ready` (active source only, like
`skin.changed`) to `notifySetupReady()`, a one-shot tick atom in
`live-sync.ts` beside the other change ticks. `useStatusSnapshot` listens
to it and runs one readiness round at once (`setup.status` +
`setup.runtime_check` + `free_tier.status`). The readiness legs also run
once on open and on return from another app, as today. The 60 s tick keeps
only `getStatus()`.

`SetupStatusSnapshot` types the record's additive fields (`ready`,
`free_tier`, `other_providers`, `inference_provider`); readiness semantics
are unchanged and still key on `provider_configured` + `runtime_check`.

Ruling: NS-845 Q1.2 (renderer half). Tests: the lifecycle branch fires one
refresh from the active source and none from another; the snapshot hook's
contract is three legs on open, one leg on the tick.

* fix(cli): the banner names the free tier's model instead of "no model configured"

The welcome banner prints before credentials resolve, so on a fresh install
`model` is empty and the banner said, in red, "no model configured — run
/model or hermes setup". Under the free tier that is false: the route is
already known from local state (identity on disk, tier on), and the first
message will run on `nous/welcome`.

`_banner_left_lines` now asks the route the same question when `model` is
empty (`guest_carries_inference()`, a local read) and shows `welcome · Nous
Research`. When nothing resolves the red line stays. Ruling: NS-845 ("the
banner's 'no model configured' line reads the resolved route").

Live: fresh HERMES_HOME + fake portal, gate on -> `welcome · Nous Research`;
gate off -> the red line, zero portal calls.

* fix(aux): vision on the free tier uses nous/welcome too

The text-only modality on the gateway's `nous/welcome` row is DeepSeek V4 Flash's, the
backing model until the repoint; `z-ai/glm-5.3-flash` is natively multimodal and the
repoint declares the welcome row `text+image->text`. Skipping Nous for vision on the
welcome host would have sent every image step past the free tier for no reason, so the
auxiliary client pins the route's one model for every lane. A backing model that takes
no images answers with the upstream's own error, which the ladder handles as it always has.

* fix(gateway): hermes gateway run is a boot owner of the free tier too

Rung 5 made every demand-time free-tier site a read: resolve_provider,
the connector token, the /login precondition. That is only correct if
every process that can reach those sites ran the bootstrap first. The
CLI (cmd_chat) and hermes serve (_lifespan) did; the standalone
messaging gateway did not. A fresh HERMES_HOME with the gate on and
`hermes gateway run` reached provider resolution with no identity to
consume, and /login returned Unavailable. Reported by @andrexibiza on
#107697 (P1).

GatewayRunner.start now runs `free_tier_bootstrap.run_bootstrap` on an
executor thread right after startup recovery and BEFORE any adapter
connects, so a fast first DM cannot arrive with nothing to resolve. It
is its own step, not part of the turn-machinery warm-up: the warm-up is
an optimisation with an off switch (HERMES_STARTUP_WARMUP_TIMEOUT<=0);
the bootstrap is correctness and must always run. With the gate unset it
is a local inventory and no network.

Live, real GatewayRunner.start against a fake portal in a fresh home:
  gate on   -> 1 create, identity persisted, resolve_runtime_provider=nous,
               /login precondition sees the identity
  gate off  -> 0 portal calls, no identity, no_provider_configured
Before the fix the gate-on row was identical to the gate-off row.

Test: the bootstrap seam runs before _start_prefilter_platforms and
delegates to the one creator. Red on 5554eb6993 (no seam), green here.

3 Free tier and signing in What Hermes gives you before you add a key or sign in, how the free tier coexists with your own API key, how to sign in, and how to turn it off.

Free tier and signing in

:::note Not on yet The free tier is being rolled out. Until it is on for everyone, nothing on this page happens unless the process was started with HERMES_GUEST_ONBOARDING=1 in its environment; without it a fresh install behaves exactly as before (the provider picker on first run). This note goes away when the rollout completes. :::

A fresh Hermes install works before you paste an API key or sign in anywhere. When Hermes starts it sets up the Nous free tier (a few seconds, shown as "Setting up free inference…") and answers on the nous/welcome model. Nothing to configure, no wizard to click through. hermes setup is still there when you want it; it is never forced.

What you get out of the box

Free tier After signing in
Inference nous/welcome (one model) Full Nous Portal catalog
Connectors (Gmail, Linear, Notion, ...) Yes Yes
Paid tools through the Tool Gateway (web search, image generation, TTS, cloud browser) No Yes, billed to your subscription
Credits or a balance None Yes

"Connectors" are the third-party accounts you link on the Nous portal so the agent can act in them. They work on the free tier without any sign-in.

Background work (conversation compaction, chat titles, image understanding, and similar) runs on nous/welcome too.

While the free tier carries inference, the banner and hermes auth status read Nous · free tier · nous/welcome, and hermes model lists a Nous · free tier row with that single model. Asking for another model on the free tier prints a pointer instead of switching silently:

gpt-5 needs a Nous account or an API key. Use /login to sign in, or /model to pick another provider.

Calling a paid tool says This needs a Nous account. Use /login to sign in. inside a chat (and names hermes auth upgrade in the terminal); the turn continues without it.

If model.default in config.yaml names something other than nous/welcome while the free tier is doing inference, Hermes uses nous/welcome anyway and says so in one line. The free tier serves exactly one model.

Using your own API key alongside it

The free tier is the last resort, never a preference. Any provider you configure wins:

You have Inference runs on Connectors
Nothing Nous free tier (nous/welcome) Free tier
An API key in .env (OpenRouter, OpenAI, Anthropic, ...) Your key Free tier
model.provider set in config.yaml That provider Free tier
A Nous Portal sign-in Nous Portal Your account

On an install that already has a provider, Hermes still sets the free tier up once at start so connectors have something to authenticate with; your provider keeps doing inference. A one-time notice says so:

Free Nous inference and connectors are now available. /model to try them, /login to sign in.

You can pick the free tier explicitly from hermes model (or /model) like any other provider.

Signing in from a chat or terminal

From a chat

Run /login in a Hermes DM on Telegram, Discord, or another supported messaging platform (on Slack use /hermes login), or in a CLI chat session. It must be a paired direct message: elsewhere Hermes replies Sign in from a direct message with Hermes. Broadcast-shaped platforms such as ntfy are refused for the same reason.

The DM gets an acknowledgement, followed by three messages: the consent link, the sign-in code on its own line, then Do not share this code. Waiting for sign-in, up to N minutes. You can keep chatting while Hermes waits, and the result is pushed into the same DM. Running /login again replaces the first code. Live sessions still on nous/welcome move to the settled model on their next message. In the Ink TUI the code appears but the confirmation does not; check /status.

:::warning One account per install /login binds this whole Hermes install to the account that approves the code: its inference, its connectors, every chat it serves. On a gateway several people can DM, set allow_admin_from for the platform (see the slash-command access guide) so only an operator can run it. :::

From a terminal

hermes auth upgrade
  1. Hermes prints a URL and a short code, and opens the browser unless you pass --no-browser or you are in an SSH session. Never share the code.
  2. Sign in to Nous Portal in the browser and confirm.
  3. Back in the terminal: Signed in as you@example.com. If your default model was nous/welcome, a second line names the model your account now uses, for example Default model is now upstage/solar-pro4:free.

Inference moves to your account's model catalog, paid tools unlock, and hermes auth status shows your account instead of the free-tier line. nous/welcome stays with the free tier: an account that was using it lands on the recommended model for its plan (the same one a fresh hermes model pick would suggest), and a default model you chose yourself is left alone. If no recommendation is available at that moment, no default is set and Hermes tells you to run hermes model.

/login in a chat, or hermes auth upgrade in a terminal, is offered wherever the free tier is present, including installs that run inference on their own API key. Signing in still unlocks paid tools for those installs.

:::note Plain login starts fresh hermes auth add nous --type oauth also signs you in, but it replaces the free tier outright and does not carry your connectors over. Use /login, or hermes auth upgrade in a terminal, when you have connectors you want to keep. :::

On Hermes Desktop

The desktop app runs on the same free tier as the CLI and shows it in four places:

Where What you see
First launch A ready screen: "Hermes is ready." with the default model nous/welcome, a Free tier badge, and Begin. "Sign in with a Nous account instead" and "Other providers" sit under it. The screen shows once.
First launch with your own API key already present A one-time strip above the composer: "Free Nous inference and connectors are now available." with Open model picker, Sign in and Dismiss.
Status bar A chip "Nous · free tier · nous/welcome" with a Sign in badge while the free tier carries inference. You can hide it from the bar's right-click menu.
Settings › Billing "You're on the Nous free tier" with one Sign in button; the summary reads Plan "Free tier", Model nous/welcome, Connectors "Included". There is no balance and nothing to pay, so no payment or usage sections appear.

Signing in from any of those places opens one dialog. It shows a code and a link; open the link (or the browser the app opened), confirm in the portal, and the dialog ends with "Signed in as you@example.com." and the default model your account now uses. A sign-in you reject in the browser, a code that timed out, or a code replaced by a newer one each show their own message and leave you on the free tier. The model picker lists the free tier as one row, "Nous · free tier", with the single model nous/welcome; there is no sign-in action inside the picker.

The desktop reads all of this from the same local state the CLI writes. The ready screen and the strip are keyed on the same one-time flag the CLI notice uses, so seeing one on the CLI means you will not see it again on the desktop for that free-tier identity, and the other way round.

Turning the free tier off

hermes config set nous.guest false

nous.guest is a normal config.yaml setting (default true), not an environment variable. With it off:

nous.guest: true (default) nous.guest: false
Free inference on nous/welcome Available Off
Connectors without sign-in Available Off
Free-tier row in hermes model Shown Hidden
Fresh install with nothing configured Chats immediately Offered hermes setup
Signing in with a Nous account Works Works

Nothing else changes. A signed-in Nous account, your own API keys, and every other provider work exactly as before. Set it back to true and the free tier returns on the next command that needs it.

What hermes logout does

Situation Result
Only the free tier is present Nothing is cleared. Hermes prints: You're not signed in. Free inference and connectors are always on. Run hermes auth to sign in with a Nous account.
Signed in with a Nous account The sign-in is removed from this profile and from the shared store, so no other profile on this machine picks it back up. With nous.guest: true the install returns to the free tier at its next start.
Another provider is active Unchanged behaviour: that provider's stored credential is cleared.

There is no command to reset or recreate the free tier. It is created once and looks after itself.

Troubleshooting

Symptom What it means What to do
First command prints It looks like Hermes isn't configured yet and offers hermes setup The free tier could not be set up within a few seconds: you are offline, or the free tier is not open on the portal Hermes is pointed at, or it is rate limited. Come back online and run the command again, or run hermes setup and add a provider of your own. Nothing is left half-configured.
Nous free tier is not open on this portal. The portal Hermes is pointed at is not offering the free tier right now. If you set HERMES_PORTAL_BASE_URL, that portal may not have it at all. Sign in with an account, unset a portal override you no longer need, or add your own key with hermes setup.
Nous free tier is rate limited; try again shortly. The portal is throttling new free-tier setups at the moment. Wait a few minutes and retry, or add your own key with hermes setup.
This needs a Nous account. You called a paid Tool Gateway tool on the free tier. /login in a chat, hermes auth upgrade in a terminal, or configure that tool with your own key in hermes tools.
Model picker shows only nous/welcome under Nous Expected on the free tier. Sign in for the full catalog, or add an API key for another provider.
The free tier stopped working after two weeks away The free-tier identity expired (see below) and is replaced at the next start, or the next time a turn or connector finds it retired. Nothing; start Hermes again. Connectors linked before the gap need to be linked again unless you had signed in.

Privacy

To make the free tier work, Hermes creates an identity on the Nous portal the first time it needs one and stores the credential in your Hermes directory, shared across the profiles under that directory. That identity holds no email address, no name, and no other personal data; it exists so inference and connector calls can be authenticated and rate limited. It expires after 14 days without use, at which point Hermes transparently creates a new one the next time you run a command. Signing in (/login, or hermes auth upgrade in a terminal) moves what that identity holds (your linked connectors) into your account. Turning the free tier off with nous.guest: false means no identity is created or used at all.
