Shanghai AI Lab releases full Atria Dawn agent model with 512K context
Overview
Shanghai Artificial Intelligence Laboratory has released the full version of Atria Dawn, an agent-oriented model built on the 744-billion-parameter GLM-5.2 base, with its context window raised from 256K to 512K tokens.
The lab reports scores of 57.5 on JobBench versus 50.3 for the preview, plus gains of 2.7 on WideSearch and 2.6 on PaperBench.
Hosted APIs for the full version are available through separate international and China endpoints, and the repository includes setup guides for SGLang, vLLM and Codex. The code is released under the MIT license. The full-release weights are listed as "Coming soon" on Hugging Face and ModelScope, so only the preview weights can be downloaded today. Pandaily reports that the repository still lists 256K for the full model.
