Benchmarks and Competitive Signal

Provider-reported** Official provider claim, not a normalized independent benchmark row.

Use this section to answer one simple question first: how much outside evidence do we have that this model performs well? Structured benchmark scores appear first, then official provider evidence, then live arena signal.

This model has official provider benchmark evidence, but not a normalized independent benchmark table yet.

A full normalized benchmark row is not available for this model yet.

Official benchmark evidence is already available below, so this release is still being tracked while the normalized table catches up.
