What the vendor claims, next to what independent boards measured. The two are never mixed in one column.

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.
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.

Hy4 is listed on OpenRouter with a 1048576-token context. Tencent posted on X that Hy4 adds vision; Arena posted that it reached #14 overall on its Agent Arena and is proprietary for now.
Why it matters: A low-priced, long-context option to test for agent work, but per Arena's post its weights are not out yet, so self-hosting is not an option today.
