 $1.69 per million tokens, balanced Balanced Summarise Chat Code gen Agentic

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

It scores **+11.4** higher and costs **73% less** ($0.450/M against $1.69/M) on this workload — and it does everything this model does.

[Gemini 3.7 Flash](/models/google__gemini-3.7-flash) is cheaper still (56% less) but drops 128K → 66K max output.

The same model via **batch** is 50% cheaper ($0.844/M) — same weights, different latency.

### Every price dimension

| Input | $0.750 /M |
| --- | --- |
| Output | $4.50 /M |
| Cached input | $0.075 /M |
| Web search | $0.01 /call |
| Batch discount | 50% |

### Independent scores

| Intelligence | 40.9 |
| --- | --- |
| Coding | 56.1 |
| Agentic | 31.5 |
| LMArena Elo | 1412.1 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.

### Capability
