1 Tool · 58 Intel
Hunyuan is Tencent's family of in-house AI models, spanning large language models as well as open-source video, image, and 3D-generation systems. Hunyuan Video, released in December 2024 with 13 billion parameters, is among the largest open-source video-generation models available, and the Hunyuan 3D models have passed 3 million downloads on Hugging Face. The line also includes the Hunyuan-Large language model, which supports context windows up to 256K tokens.

Generates high-quality 3D scenes from a single image or text prompt in seconds on one GPU.

HY-WU synthesizes instance-conditioned LoRA updates from hybrid image-instruction representations and injects them into a frozen backbone during the forward pass, producing a per-input adapter with no test-time optimization. The premise is that shared LoRAs compromise across objectives while single-domain ones fail to generalize.
Day-zero vLLM support for Hy4-preview, verified on NVIDIA GPUs. The serving notes expose the architecture: 256 routed experts plus one shared, a 1M context where each query attends to just 2048 tokens, and only 21 of 78 layers computing their own sparse index.
A memory plugin for persistent agents such as OpenClaw, built on a six-layer framework with a System1/System2 split and a three-stage consolidation chain. Tencent reports 70%+ fewer stored memories, 45% higher density per memory and 35% fewer tokens on very long contexts.
Two open translation models on a shared lineage: a 1.8B aligned by on-policy distillation for consumer hardware at a 1GB footprint and 0.18s latency for 50 tokens, and a 7B upgrade of Tencent's WMT25 winner. Custom terminology, long-dialogue context and format preservation supported.
Tencent surfaced HyCreator, an agent harness aimed at long video generation. Its end-to-end auto mode targets 10-minute-scale films with no human in the loop, and users can drop into real-time interactive editing at any point. Early access is open.
A step-distilled 480p image-to-video checkpoint for HunyuanVideo 1.5 cuts sampling to 8 or 12 steps, a roughly 75% reduction in end-to-end time and under 75 seconds on a single RTX 4090, with quality held near the original. Four steps trades quality for more speed.
Tencent releases the training code for WorldMirror, the Hunyuan World 1.1 model that turns video into 3D worlds in about a second and maps any input, whether image, video, or 3D prior, to 3DGS, depth, cameras, normals, or point clouds. A hosted demo is live.
An RL post-training framework aimed squarely at interactive world models, released with training code you can point at your own data, rewards or base model, plus a checkpoint. The reported gain is following compositional action instructions and staying coherent over long interactions.
Hy-MT1.5-1.8B quantized to 1.25 bits: 3.3GB at FP16 down to 440MB, roughly 25% smaller and 10% faster than 1.67-bit approaches with no claimed accuracy loss. Covers 33 languages, 5 dialects and 1,056 directions, with an Android demo, weights, code and a paper.
Using the Hyra research agent on Hy3, Tencent reports an explicit construction showing the optimal exponent relating |A+A| to |A-A| is exactly 2, a gap open since a 1969 upper bound, where prior constructions barely passed 1.1. A paper and a formal proof are published.
