Hy-Memory-30B-A3B is a specialized language model from Tencent Hunyuan for writing persistent memories in frameworks such as Mem0, Hy-Memory, and MemOS. Hugging Face file metadata counts 30.06 billion total parameters. The model card says approximately 3 billion are active. Its config supports exactly 262,144 context tokens.

The model accepts text and uses Apache 2.0. Tencent evaluates it across four memory frameworks, with EverMemOS held out. The published tables average six metrics per framework on fixed 20% subsamples.
