【New】 LongCat-DeepResearch
LongCat-DeepResearch combines a LongCat model enhanced for deep research with a research harness for open-ended investigation and evidence-grounded report generation. The system outperforms the evaluated deep-research offerings from ChatGPT, Claude, and Gemini across DeepResearchBench, DeepResearchBench II, and ResearchRubrics. These model improvements are intended to be incorporated into the next general-purpose LongCat model release.
Open foundation models for long-context reasoning, agentic coding, and scalable AI systems. Home of LongCat-2.0.
