backend deprecated models check - 2026-09-11

Automated check of the backend's hardcoded model lists against the live model API (`https://ai-models.puter.work/`).

Reports **only deprecated** models — backend entries whose id and none of whose aliases appear anywhere in the upstream name set (upstream `id` + `name` + every `aliases` entry, lowercased, `models/` prefix stripped). Read-only; no files were modified.

Repo commit checked: `9940beb`

## Deprecations

**chat/openai (1)**
- `o3-pro`

Notes: upstream still serves `o3`, `o3-mini`, `o3-2025-04-16`, `o4-mini` — only the `-pro` variant is gone. Backend aliases `o3-pro-2025-06-10` and `openai/o3-pro` are also absent upstream.

**chat/mistral (2)**
- `mistral-large-2512`
- `zai-glm-5-2`

Notes: the Mistral endpoint's full model list has no `mistral-large*` entry at all (`mistral-large-latest` doesn't resolve either) — only small/medium/ministral/codestral/magistral/voxtral remain. `zai-glm-5-2` (`glm-5-2`), a third-party GLM model hosted on Mistral's infra, also has no upstream entry.

**chat/deepseek (2)**
- `deepseek-v4-flash`
- `deepseek-v4-flash-vision-exp`

Notes: the DeepSeek endpoint now lists only `deepseek-flash` and `deepseek-v4-pro`. Neither backend model's id nor any of its aliases (`deepseek-chat`, `deepseek-reasoner`, etc.) matches upstream — `deepseek-v4-pro` itself is unaffected and still resolves.

**tts/xai (1)**
- `xai-tts`

Notes: this is the only entry in `ai-tts/providers/xai/costs.ts`, so the whole xAI TTS provider is affected. The xAI endpoint does cover non-chat modalities (it lists `grok-imagine-image*`, matching the backend's image models), but contains no tts/speech/audio/voice model under any id or alias. Same as prior weeks' finding — worth a manual confirmation before removal, since xAI may simply not expose TTS on this listing.

## Clean (no deprecations)

chat: claude, gemini, moonshot, minimax, xai, zai, alibaba  ·  image: gemini, openai, xai  ·  tts: gemini, openai  ·  video: gemini

(No `ai-video` provider exists for openai in this repo, so that pair was not applicable to check.)

## Verify manually

**zai**: none — the endpoint returned its full 10-model catalog (`glm-5.3`, `glm-5.3-flash`, `glm-5.2`, `glm-5.1`, `glm-5`, `glm-5-turbo`, `glm-4.7`, `glm-4.6`, `glm-4.5`, `glm-4.5-air`) and every backend zai model matched directly this run.

Start by locating the backend hardcoded model lists for the reported chat providers and inspect ai-tts/providers/xai/costs.ts. Compare each listed model and alias with the live provider catalogs, manually confirm whether xAI exposes TTS, and check the affected entries before changing anything. Done means confirmed deprecated entries are removed or updated without affecting the models marked clean.
