## No independent quality score.

No benchmark we track has measured this model. That is not the same as measuring it and finding it wanting — we simply cannot rank it, so we do not.

### Every price dimension

| Input | $1.10 /M |
| --- | --- |
| Output | $4.40 /M |
| Cached input | $0.550 /M |
| Web search | $0.01 /call |

### Independent scores

| LMArena Elo | 1336.6 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.

### Capability
