"""DeepInfra video generation backend.

DeepInfra serves video over the OpenAI-compatible ``/v1/openai/videos`` endpoint (async job:
``create`` → poll → ``download_content``), so all SDK plumbing lives in
:class:`agent.video_gen_provider.OpenAICompatibleVideoGenProvider`. This plugin only declares
identity, credentials, and live model discovery — no hardcoded model ids, so retired models drop
out without a patch. Mirrors ``plugins/image_gen/deepinfra``.
