Introducing LongCat-2.5, our latest natively multimodal agentic model with 1.6T total parameters and ~48B active.
Built for long-horizon agentic tasks, it brings stronger visual understanding and agentic coding to work ranging from complex coding projects to visual coding such as creative design and 3D tasks.

LongCat-2.5 scales an end-to-end agentic RL pipeline across data, environments, algorithms and harnesses for long-horizon tasks, and its MOPD training retains the previous model's expert groups:
Per-cut prefixes and segment-capped student rollouts keep long responses stable, while shared prefill, KV-cache reuse and Tree Attention keep sampling and training cheap.

3D Artifact Showcase
Build a 3D artifact interactive display page generator with LongCat-2.5. Combining WebGL rendering and frontend interactions, it generates dynamic pages with 3D models (e.g., the Sanxingdui bronze sacred tree), controls (drag-to-rotate, scroll-to-zoom, double-click-to-focus, and wireframe toggle), and historical/cultural info panels — ideal for online 3D digital exhibitions and cultural education pages.
