Hy-SimulMT continuously translates spoken conversation between Chinese and English. Tencent reports scores for FLEURS, CoVoST2, ACL6060, and RealSI-Sentence, plus a long-form evaluation on RealSI. The publisher reports about three seconds of StreamLAAL. This measures streaming translation lag, not time to first audio.

Hy-Nomas generates an interactive world through successive video segments. Text instructions, camera paths, and prior history guide which objects, actions, and viewpoints appear in the next segment. Its diffusion backbone has eight billion parameters. The released standard configuration renders 720 × 1280 pixels at 24 frames per second and uses eight DiT denoising steps.

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.

Hy3 preview was released as an open-weight preview for practical agent work. Tencent uses a Mixture-of-Experts model with 295 billion total parameters, 21 billion active per token, and a 262,144-token context. The model supports no_think for direct responses and high for harder reasoning tasks.
Image model · January 2026
HunyuanImage 3.0 Instruct can rewrite prompts and use CoT Think in addition to text-to-image and text-image-to-image. The instruction-tuned open-weight variant has 80B total and 13B active parameters and targets precise instructions, layout, and iterative editing.

Hunyuan A13B Instruct separates fast and slow thinking in a sparse 80-billion-parameter model with about 13 billion active per token. Fine-grained mixture-of-experts routing and grouped-query attention keep active compute limited. For agents, the model card documents a specialized vLLM parser for tool calls and internal reasoning steps.
