LongCat-2.0 focuses on long-context code understanding, generation and agent execution: developers provide project code and requirements, then connect tools for refactoring, application development or information processing. The family offers hosted access alongside released weights and inference materials. Self-hosting requires suitable hardware and an inference environment; the website’s workspace is a separate interface.",
