Who it is for

• Teams choosing a default model for a product and wanting the whole board, not just the top row.
• Anyone comparing price per token with rank, looking for the point where a cheaper model stops failing.

How to read these numbers

An Arena score comes from blind pairwise comparisons, not from an absolute quality scale. A few points between neighbouring rows is often inside the error bars, so the top of a board is better read as ‘roughly one tier’. Price, context and licence are stated specs and do not feed the score.

What to check yourself

• Whether the model is available in your region and whether access terms changed since the snapshot.
• Whether you really need the stated context: attention quality on long input is often lower.
• How price behaves on your prompt mix: the input/output ratio can matter more than the headline figure.
