LongCat 2.0 is a sparse mixture-of-experts language model from Meituan, with 48B active parameters out of 1.6T total. It is suited for coding, repository-level changes, long-horizon problem solving, and agentic...
The relace-search model uses 4-12 `view_file` and `grep` tools in parallel to explore a codebase and return relevant files to the user request. In contrast to RAG, relace-search performs agentic...
LongCat 2.0 is open-weight and competitive on many tasks, but Relace Search may still lead on the hardest reasoning and agentic work. The gap keeps narrowing — benchmark both on your actual use case before deciding.
Yes. LongCat 2.0 has open weights, so you can self-host it on your own GPUs or run it via a low-cost API. Relace Search is API-only and cannot be self-hosted.
LongCat 2.0 costs $1.2/M output vs $3/M for Relace Search — roughly 3x cheaper via API, and free if you self-host.
Choose LongCat 2.0 if you want to self-host, keep your data private and skip per-token fees — it's open-weight and runs on your own hardware. Choose Relace Search if you want frontier capability through a managed API with zero infrastructure to run.
