Meituan is a Chinese on-demand services giant (food delivery, local commerce) that pivoted aggressively into AI, open-sourcing frontier-scale models under the LongCat brand.
Recent Developments
- 2026-06-30: Open-sourced LongCat-2.0 — 1.6T-parameter MoE, 1M-token context, MIT license (2026-06-30-meituan-longcat-2-domestic-chips)
- Previously operated anonymously as “Owl Alpha” atop OpenRouter leaderboards
- Claims first trillion-scale model with full pre-training and inference on 50,000-card domestic Chinese ASIC cluster (Huawei HCCL interconnect)
- Benchmark claims: SWE-bench Pro 59.5, Terminal-Bench 70.8 (company-reported)
Warning
Domestic ASIC identity and independent hardware verification remain limited. Some prior Chinese lab domestic-chip claims may include smuggled Nvidia hardware per AFP-sourced reporting.
