Qwen3.6-27B beats much larger predecessor on most coding benchmarks

Alibaba released Qwen3.6-27B, a 27B-parameter dense open-source model, through cloud APIs and open weights.

It reportedly beats the much larger Qwen3.5-397B-A17B on most coding benchmarks, including SWE-bench Verified and Terminal-Bench 2.0.

The model also matches rivals on some reasoning and multimodal tests, narrowing the gap with top proprietary systems.

The result highlights how a smaller, more practical model can deliver strong coding performance at lower deployment cost.
