 $5.63 per million tokens, balanced Balanced Summarise Chat Code gen Agentic

## GPT-5.6 Sol is both better and cheaper.

It scores **+7.8** higher and costs **29% less** ($4.00/M against $5.63/M) on this workload — and it does everything this model does.

[GLM 5.3](/models/z-ai__glm-5.3) is cheaper still (62% less) but drops 1.1M → 1.0M context, no image, file input.

The same model via **batch** is 50% cheaper ($2.81/M) — same weights, different latency.

### Every price dimension

| Input | $2.50 /M |
| --- | --- |
| Output | $15.00 /M |
| Cached input | $0.250 /M |
| Web search | $0.01 /call |
| Batch discount | 50% |

**Past 272,000 tokens the price changes.** Input goes to $5.00/M (2×) and output to $22.50/M. The headline rate does not apply to a long-context workload.

### Independent scores

| Intelligence | 53.1 |
| --- | --- |
| Coding | 71.1 |
| Agentic | 44.2 |
| LMArena Elo | 1469.6 high |

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.
