When to choose each
Claude Sonnet 5
Best for
- Agentic coding evaluations with current introductory API pricing
Watch out for
- The launch price is introductory through 2026-08-31; refresh pricing before evaluating workloads after that date
Qwen3.8-Max
Best for
- Output-heavy generation workloads where the $6 per million output rate is the deciding factor
- Agentic and coding evaluations that need a 1M-token window at mid-tier cost
Watch out for
- Two releases share the name: the original 3 August 2026 model and the 0902 refresh. The rates and limits here are read from the 0902 listing
- Reported benchmark placements come from Alibaba and from public arena boards rather than a common pinned snapshot, so they are not comparable with the LiveBench results in this dataset
