It is available in LongCat chat and API; GitHub and Hugging Face releases are promised but not out yet. ## Key facts - 1.6T total, ~48B active parameters (TechNode, citing IT Home) - Capabilities claimed: visual coding, creative design, 3D tasks, complex codebases and full software projects - Open weights: planned, not released as of Nov 2 ## What happened See summary. Benchmarks were not stated in the coverage we could read; Meituan's own page was not checked. ## Your AI and this story - GPT-6 Astra (training cutoff April 2026): 186 days after its cutoff - Claude Opus 5.5 (training cutoff June 2026): 125 days after its cutoff - Gemini 4 Argon (training cutoff March 2026): 216 days after its cutoff - Grok 4.7 (training cutoff May 2026): 155 days after its cutoff ## Sources 1.
