Atria Dawn Preview is an agentic language model released by Shanghai Artificial Intelligence Laboratory, built on the 744B-parameter MoE GLM-5.2 foundation (753B parameters per the Hugging Face model card, including additional components). It targets research and engineering scenarios requiring continuous environmental understanding, tool use, and multi-step task completion, and was released quietly on September 11, 2026 with MIT-licensed weights on Hugging Face and ModelScope. The model is text-only (not multimodal), supports local deployment (BF16/FP8 via vLLM or SGLang) as well as hosted API access, though no official per-token price has been published.
