What the vendor claims

Quoted word for word from the vendor's own launch post or model card. Claims, not measurements.

No vendor claims recorded yet. They come from launch posts and model cards the Drops covered.

Independent results

Measured by independent sources (Epoch AI, LMArena, OpenRouter's benchmark runs, τ²-bench, Vectara), not by the vendor. "Listed as" is the source's own name for the model, so you can check our match.

No independent results yet. They appear here as Epoch AI and LMArena add this model.
