Atria Dawn Preview is a preview-stage agentic model from Shanghai AI Laboratory (published under the internlm Hugging Face org), built on a 744B-parameter MoE foundation (the model card states it is trained on the GLM-5.2 base). It targets research and engineering workflows requiring sustained environment understanding, tool use, and multi-step task completion across four capability areas the vendor calls Discovery, Creation, Delivery, and Cybersecurity. The Instruct model accepts text-only input (image/PDF input returns an API error) with a 256K-token context window. Weights are released under the MIT license on Hugging Face and ModelScope in BF16 and FP8 formats. It is served via an international API at api.atria-asi.ai (Chat Completions, Messages, and Responses wire formats) and a China-region endpoint; no per-token pricing has been published on either endpoint as of this writing.
