Category Breakdown
Qwen3.7-Max at $2.50 per million vs Claude Opus 4.7 at $15. Six times cheaper on input.
Qwen3.7-Max at $7.50 per million vs Claude Opus 4.7 at $75. Ten times cheaper on output.
Both models ship a 1,000,000 token input window. Even on raw context budget.
Qwen3.7-Max scored 57, first place on the public leaderboard. Claude Opus 4.7 has not been re-scored at the same threshold under this iteration.
Claude Opus 4.7 published HumanEval at 96.2 and remains the published top result on SWE-bench Verified. Alibaba has not published competitive scores on these specific suites.
Claude Opus 4.7 leads with GPQA Diamond 76.5 and MATH 93.1. Qwen3.7-Max leans more on aggregate Intelligence Index than per-suite reasoning scores.
Alibaba claims Qwen3.7-Max can run autonomously for up to 35 hours on multi-step missions. Claude does not publish a comparable continuous-operation figure.
Anthropic owns the Model Context Protocol spec and ships first-class MCP tooling. Qwen supports tool use but does not lead the spec.
Claude Opus 4.7 ships native vision. Qwen3.7-Max is text-focused at launch.
Qwen3.7-Max cached input drops to $0.25 per million tokens, a 90 percent discount via OpenRouter. Anthropic offers prompt caching but at a smaller relative discount.
Choose Qwen3.7-Max when:
- ▸Cost-sensitive 1M-context workloads at scale
- ▸Long-horizon agent loops that sit on the same context for hours
- ▸High-volume repeated-context calls where the 90 percent cache discount compounds
- ▸Teams comfortable with proprietary Chinese-hosted models
Choose Claude Opus 4.7 when:
- ▸Code generation and SWE-style tasks where HumanEval and SWE-bench scores drive selection
- ▸MCP-first agent stacks and the Anthropic developer ecosystem
- ▸Vision and multimodal workloads
- ▸English-heavy academic reasoning where GPQA and MATH scores matter
