Overview
Qwen3.5 9B is Alibaba's dense 9B release from March 2026 under Apache-2.0. It takes text and image input, runs a 256K context, and covers 201 languages. The qwen3.5 family is at 15.7M Ollama pulls (#14 in the library); the Q4_K_M build is 6.6GB.
Strengths
- 201-language coverage in a 9B footprint
- Apache-2.0 license with commercial use allowed
- 6.6GB Q4_K_M leaves KV-cache headroom on 12GB cards
Weaknesses
- Image input only on the multimodal side — no audio
- 9B quality ceiling on hard reasoning versus 12-20B peers
- Filling the 256K window needs far more VRAM than the weights suggest
