Follow-ups on top of the salvaged #82631 surface:
- _select_surface: an unknown model id found in the live /images/models
catalog now ROUTES to the dedicated Image API instead of only logging a
hint — without this, a model picked from the live picker that postdates
the curated snapshot would fall onto chat-completions and fail. Curated
defaults stay pinned to chat (no behaviour change for existing setups);
offline probes still fall back to chat. _HINTED_MODELS removed.
- list_models (OpenRouter): union of the live GET /images/models catalog
(43 models today) and the chat-completions image models, deduped,
defaults first; curated metadata wins for known ids, API names for the
rest. Nous Portal (no /images route) keeps its chat-only catalog.
Offline fallback: static chain + curated Image API snapshot.
- Tests updated/added: unknown-id routing (flipped from the hint-only
pinning test), non-catalog id stays on chat, merged-picker union/dedupe/
order, Nous exclusion.
- Docs: image-generation.md gains the OpenRouter Image API section and an
editing-support row.
Live-verified: picker lists 43 models; generation succeeded through the
dedicated API on google/gemini-3.1-flash-lite-image and on the previously
unreachable black-forest-labs/flux.2-klein-4b (config-selected, no kwarg).
- plugins/image_gen/openrouter: list_models() now queries the endpoint's
/models catalog filtered to output_modalities containing "image"
(per-backend 5-min cache, 10s timeout, static 2-model chain as offline
fallback; openrouter/auto* router pseudo-models excluded). Every image
model OpenRouter serves — including future releases — is selectable in
`hermes tools` with no code change. Applies to Nous Portal too via the
shared provider class.
- plugins/image_gen/xai: forward the dispatched model kwarg into
_resolve_edit_model() so an explicitly selected edit-capable model is
honored on /images/edits (extends the salvaged #55893 fix to the edit
path; text-only models still fall back to quality).
- Tests: OpenRouter live-catalog filtering/exclusions/order, offline
fallback, cache single-fetch; xAI edit-kwarg forwarding incl. the
text-only-hijack negative case.
Live-verified against openrouter.ai: 9 image-output models returned and
rendered, matching the public models?output_modalities=image listing.
Follow-up to the per-provider guards. Three improvements from review:
1. Extract agent.file_safety.raise_if_read_blocked() as a single shared
chokepoint and route the OpenAI, OpenRouter, and (newly) xAI image
providers through it, replacing the 3x-duplicated inline try/except.
Fixes the whole bug class: xai/_xai_image_field read a model-supplied
local path via open() with no guard — the same vulnerability the PR
fixed for OpenAI/OpenRouter, in a sibling provider it missed.
2. Strengthen the regression tests from pass-on-any-ValueError to true
security invariants: spy open()/read_bytes() and assert the blocked
credential is NEVER read; add negative controls (legit local image
still loads; remote/data: URIs pass through unguarded) so a
block-everything regression can't pass.
3. Guard is best-effort by design (defense-in-depth, not a security
boundary) — documented on the shared helper.
- agent/file_safety.py: raise_if_read_blocked()
- plugins/image_gen/{openai,openrouter,xai}: route through helper
- tests: no-read spies + negative controls across all three providers
The cherry-picked fix added explicit-kwarg and top-level image_gen.model
resolution but left _resolve_model / _resolve_model_chain docstrings stating
the old 'env override -> config -> DEFAULT_MODEL' order. Document the full
precedence (explicit kwarg -> env -> scoped -> top-level -> default chain) to
match the sibling krea/openai providers.
hermes tools persists the selected model to image_gen.model, but the
OpenRouter-compatible provider only read scoped image_gen.<provider>.model
and ignored the dispatch model kwarg — so Nous users always hit the default
quality-first chain and fell back to Gemini.
The quality-first default (OpenAI image via OpenRouter) is slow, and a full
hatch fans out ~8 rows with up to 3 retries each (300s/call) across 2 parallel
waves, so the absolute backend worst case is ~30 min. The old ceilings fired
mid-run:
- per-image HTTP call: 180s -> 300s (a single cold row can exceed 3 min)
- drafts RPC: 240s -> 420s (single wave, no retries — 7 min is ample)
- hatch RPC: 420s -> 1hr (sits above the ~30 min backend worst case)
The hatch ceiling is intentionally well above the realistic max so the frontend
never throws "request timed out" before the backend has exhausted its own
retries. The background-resumable notification path remains the real UX safety
net — the user can close the modal and get pinged on completion.
OpenRouter/Nous image gen now runs a quality-first model chain by default:
attempt the highest-fidelity OpenAI image model first, then fall back to
Gemini 3 Pro Image when it's access-gated/unavailable/times out. An explicit
OPENROUTER_IMAGE_MODEL / config model override pins one model with no fallback.
Atlas validation rejects malformed model output instead of shipping it: adds a
per-state collapse guard (a single sliver/fragment row no longer passes because
other rows are healthy), on top of the existing postage-stamp + multi-pose
checks.
Desktop: pet-gen native notifications are now "global" (not tied to a chat
session), so a background generation started from the command center fires an
OS notification when the user is away even with no active session. Adds a
neutral "This can take up to 5 minutes." banner on step 1, and lets the
provider picker auto-size.
Tests updated/added for the OpenRouter fallback chain, the collapse guard, and
the global notification path.
Reference-grounded image provider over the OpenRouter-compatible
chat-completions image protocol (Gemini Flash Image et al.). Nous Portal
proxies OpenRouter, so one provider serves both — giving pet generation a
reference-capable backend beyond OpenAI gpt-image.
