 $6.00 per million tokens, balanced Balanced Summarise Chat Code gen Agentic

## Gemini 3.7 Flash is both better and cheaper.

It scores **+26.2** higher and costs **88% less** ($0.750/M against $6.00/M) on this workload — and it does everything this model does.

[GLM 5.3](/models/z-ai__glm-5.3) is cheaper still (64% less) but drops no image, file input.

### Every price dimension

| Input | $3.00 /M |
| --- | --- |
| Output | $15.00 /M |
| Cached input | $0.300 /M |
| Cache write | $3.75 /M |
| Cache write 1h | $6.00 /M |
| Web search | $0.01 /call |

**Past 200,000 tokens the price changes.** Input goes to $6.00/M (2×) and output to $22.50/M. The headline rate does not apply to a long-context workload.

### Independent scores

| Intelligence | 29.8 |
| --- | --- |
| Coding | 37.6 |
| Agentic | 17.6 |

Sources are listed separately rather than averaged. Across the 62 models both have scored they correlate at r = 0.806 — close agreement overall, but four models rank very differently between them, and a blended score would hide exactly those.
