Qwen3.5-397B-A17B (Feb 2026) is Alibaba's current open flagship — a 397B/17B-active multimodal Apache-2.0 MoE that brings frontier reasoning and coding into self-hostable form.
Best for
- The strongest fully-open Qwen — frontier reasoning + coding + multimodal
- The open alternative to the closed Qwen Max line
- Far higher throughput than Qwen3-Max at long context
- 201-language coverage for broad multilingual work
How it compares — and the India angle
- Apache 2.0 lets Indian firms self-host with full data residency (DPDP-Act friendly) and zero per-token cost.
- 201 languages include usable Hindi/Indic support — though benchmark against Sarvam/IndicTrans for heavy Indic work.
- Frontier capability without the closed Max line's API-only lock-in.
