backend new models check - alibaba - 2026-09-16

Files checked: `src/backend/drivers/ai-chat/providers/alibaba/models.ts`

**chat (3)**
- `qwen3.8-flash` | aliases: n/a | context: n/a | created: 2026-08-26 | price: see provider pricing page
Notes: new Flash tier of the Qwen3.8 family — backend already has `qwen3.8-max`, `qwen3.8-27b`, `qwen3.8-2.4t-a95b` but not `qwen3.8-flash`. Genuinely missing, recent (3 weeks old).
- `qwen-flash-character` | aliases: n/a | context: n/a | created: 2026-04-10 | price: see provider pricing page
Notes: character/roleplay-tuned deployment of `qwen-flash`; not present under any name in backend.
- `qwen-plus-character` | aliases: n/a | context: n/a | created: 2026-04-10 | price: see provider pricing page
Notes: character/roleplay-tuned deployment of `qwen-plus`; not present under any name in backend.

Notes: `qwen3.8-max-0902` (created 2026-09-02) is a dated snapshot of the already-backed `qwen3.8-max` — per the noise rule it is NOT new; suggest adding `qwen3.8-max-0902` as an alias on the existing `qwen3.8-max` entry. Also excluded as non-chat modalities (image-gen, TTS, ASR, live-translate, omni-realtime voice, captioning, OCR, embeddings): 56 qwen-family entries (18 qwen-image-*, 16 qwen3-tts-*, 5 asr-*/qwen-audio-*-asr-*, 6 livetranslate-*, 7 omni-*-realtime, plus qwen3-s2s-flash-realtime, qwen3-omni-30b-a3b-captioner, qwen-vl-ocr-2025-11-20, qwen3.7-text-embedding) — this backend is chat-only.

third-party rehosts (non-qwen), not real alibaba models: 24
legacy upstream models not in backend (verify intent): `qwen-coder-plus` (2025-10-14, pre-Qwen3 coder line, superseded by the already-backed `qwen3-coder-plus`/`qwen3-coder-flash`), `qwen2-7b-instruct` (2025-08-21, superseded Qwen2 generation)

Start in src/backend/drivers/ai-chat/providers/alibaba/models.ts and compare the existing qwen3.8 entries with the three missing chat models listed in the issue. Add the missing model definitions and the qwen3.8-max-0902 alias as appropriate, then verify the Alibaba chat model list and any available project checks.
