Strengths
- Best open-weight frontend result on Arena WebDev Frontend (1643, rank 8)
- Vision2Web 64.0 - a directly frontend-relevant visual web-dev score
- LiveCodeBench v6 91.9 and SWE-bench Pro 62.5% at $0.15/$0.47
- 125B total / 6B active parameters makes self-hosting comparatively cheap
Tradeoffs
- Qwen Community License 1.0 restricts commercial MaaS use without a separate agreement
- Native context is 262K, not 1M - reaching 1M needs config changes when self-hosted
- The weights and the hosted API are documented as different artifacts, so benchmarks may not transfer
- Only 1,720 Arena votes
