On November 2, 2026, the Meituan LongCat team released LongCat-2.5, a native multimodal model designed for long-horizon agentic tasks, with a total parameter count of 1.6 trillion and approximately 48 billion parameters activated per token. According to a Phoenix Technology report, the model leads Claude-Opus-5 and GPT-5.6-Sol on benchmarks published by Meituan such as AutomationBench and LongCatClawBench, and scores 38.5 on Terminal Bench v4.0, surpassing GPT-5.6-Sol but trailing Claude-Opus-5; the model converts visual signals into multi-level discrete tokens and processes them uniformly with text, and redesigns its parallel strategy to address the under-80GB memory per card of domestic accelerators, raising single-card throughput for long-sequence SFT by 86% over the DDP baseline. China.com Technology reported the same day that the model was trained entirely on domestic compute, with scores on multiple mainstream benchmarks falling between Claude-Opus-4.8 and Claude-Opus-5 and some evaluations surpassing Claude-Opus-5; Meituan also launched "Miaoshou," an AI business operations workbench built on the LongCat series.

Meituan Releases LongCat-2.5 Large Model, 1.6 Trillion Parameters Trained Entirely on Domestic Compute
Meituan has released its next-generation large model LongCat-2.5, a natively multimodal model designed for long-horizon agent tasks, with 1.6 trillion total parameters, trained entirely on domestic compute. During the mid-training stage, the model conducted long-context training with sequences of up to 1M tokens, with cumulative training volume reaching trillions of tokens, and it optimized task division around supernodes to address the challenge of small per-card memory in domestic compute. Meituan says its results on multiple mainstream benchmarks fall between Claude-Opus-4.8 and Claude-Opus-5, and it surpasses Claude-Opus-5 on some evaluations.

Meituan LongCat releases LongCat-2.5 native multimodal model, 1.6T parameters targeting long-horizon agent tasks
Meituan LongCat releases the native multimodal model LongCat-2.5, with a total parameter count of 1.6 trillion and approximately 48 billion parameters activated per token, strengthening native visual understanding and agentic coding capabilities on the basis of LongCat-2.0. The model incorporates more long-horizon trajectory data into long-sequence training, and through large-scale long-horizon reinforcement learning enhances end-to-end engineering capabilities such as complex codebase development and complete project construction, while representing visual signals as multi-level discrete tokens to uniformly process visual and textual inputs. The official statement says it has optimized long-context training and W4A4 inference on domestic compute, and it will soon be available on GitHub and HuggingFace.
