hy3Hy3
overview.
Hy3 is an open-weight model from Tencent Hunyuan. It is the earlier Hunyuan entry in this catalog, with a published context reference and its own external evaluation. Hy4 Preview is listed separately and has no matched result on this index, so the chart does not establish a quality ranking between the two.

Compare models in the AELDER catalog on the same external measure. The Artificial Analysis Intelligence Index combines evaluations of model capability. Higher is better; the score is not a percentage.
