Architecture, strengths and use cases
LongCat-2.0 is an official self-hostable Meituan release in the LongCat General track. It uses Not published by manufacturer, carries Not published by manufacturer, supports a verified context window of 0 tokens, and exposes only source-certified checkpoints and runtime combinations. Its release, license and deployment facts are tied to the official repository revision rather than inferred from the family name.
LongCat-2.0 uses Not published by manufacturer with Not published by manufacturer. The stored architecture profile records layers, hidden width , attention heads and a 0 token context ceiling where the official configuration publishes those fields.

Only exact, source-certified variants attached to this release are shown.
Recommended hardware
Use only the listed certified runtime configuration with the exact checkpoint precision. The recommendation engine checks weight memory, KV cache, runtime overhead, safety headroom, GPU architecture and topology before ranking rentable and reference hardware.
Reference only
The official license permits commercial use; its obligations still apply.
License and self-hosting considerations
The full 0B resident weight set must fit across the selected GPUs. Context and concurrency add KV-cache memory; MoE active parameters do not replace resident-weight memory.
LongCat-2.0 is published under mit. The release-scoped official license link and verification date are retained with the catalogue record.
Commercial Use Allowed. The official license permits commercial use; its obligations still apply.
