Add the models that landed on models.dev since the September 4 curation pass (#28955), plus cross-provider gaps where a model was curated on one provider but not on the others that serve it, so they appear as suggestions when an admin adds a chat model in /agents settings.

Model Added to
GPT-6 Astra azure, openrouter, vercel (already curated on openai)
Claude Mythos 5.1 anthropic. Not on models.dev, so injected in overrides.jq as a copy of claude-fable-5-1, mirroring the existing claude-mythos-5 injection. Anthropic's pricing page lists Mythos 5.1 at the same rates as Fable 5.1, including the reduced cache-read rate.
DeepSeek V4.1 Flash openrouter, vercel
Gemini 3.8 / 3.7 / 3.6 Flash openrouter, vercel (no Google models were curated on either gateway)
Gemini 3.1 Pro Preview, Gemini Flash-Lite Latest, Gemini 3.5 Flash Lite google (the catalog had no Pro or Lite tier)
Claude Mythos 5 azure (left pending in #28887)
Claude Opus 4.7 azure, bedrock (plus global. alias), openrouter, vercel
GPT-5.5, GPT-5.4 mini openrouter, vercel
GPT-5.4, GPT-5.4 mini, GPT-5.3 Codex azure
Grok 4.6, Qwen3.8 Flash, GLM 5.3 Flash, MiniMax M3, Kimi K2.7 Code openrouter, vercel

Mythos 5.1 uses reasoningEffort: high like Fable 5.1 and is added to the Anthropic thinking-mode pin in knownModelsGenerated.test.ts. Gateway entries follow the existing convention: no reasoning default and upstream display names. New entries sort ahead of the models they supersede.

Deliberately not added: openai.* models on Bedrock (chatd's Bedrock provider wraps the Anthropic client, so they cannot be used from Coder Agents), models.dev's ~-prefixed rolling aliases on OpenRouter, and copilot (unsupported in chatd).

knownModelsGenerated.json and coderd/aibridge/prices/data/prices.json are regenerated with make gen/aibridge-prices from the same models.dev snapshot. Apart from the claude-mythos-5-1 row, the prices.json changes are upstream drift since the last weekly refresh, the same content the scheduled refresh PR would produce.

Validation: go test ./scripts/aibridgepricesgen/... ./coderd/aibridge/prices/... and pnpm test src/modules/aiModels/ (174 tests) pass.
