# GPT-5 Mini

 $0.688 per million tokens, balanced Balanced Summarise Chat Code gen Agentic

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

It scores **+26.5** higher and costs **35% less** ($0.450/M against $0.688/M) on this workload — and it does everything this model does.

[DeepSeek V4 Flash 0731](/models/deepseek__deepseek-v4-flash-0731) is cheaper still (85% less) but drops no image, file input.

The same model via **batch** is 50% cheaper ($0.344/M) — same weights, different latency.

### Every price dimension

| Input | $0.250 /M |
| --- | --- |
| Output | $2.00 /M |
| Cached input | $0.025 /M |
| Web search | $0.01 /call |
| Batch discount | 50% |

### Independent scores

| Intelligence | 25.8 |
| --- | --- |
| Coding | 15.6 |
| Agentic | 19.6 |
| LMArena Elo | 1373.4 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.
