Shanghai AI Lab Releases Atria Dawn Preview, a 744B-Parameter Agentic Model

Shanghai Artificial Intelligence Laboratory has released Atria Dawn Preview, a new agentic model built on the 744-billion-parameter mixture-of-experts (MoE) GLM-5.2 foundation model. The model is available now on Hugging Face and ModelScope, published under the internlm organization, and supports a 256,000-token context window.

Atria Dawn Preview is a text-only instruct model — it does not accept image, PDF, or other binary inputs. The lab ships two versions: a standard instruct model and an FP8-quantized variant, both with the same 256K context limit. Pricing for hosted API access has not been disclosed.

Designed for multi-step agentic work

According to Shanghai AI Lab, the model is built for "continuous environmental understanding, tool use, and multi-step task completion," combining task objectives with environmental feedback across a full loop of problem analysis, tool use, code implementation, experiment execution, and failure recovery. The lab frames the model's capabilities across four use-case categories: Discovery (research and evidence retrieval), Creation (software and ML system building), Delivery (turning data into reports and presentations), and Cybersecurity (vulnerability analysis and remediation in authorized environments).

Benchmark claims

Shanghai AI Lab published comparisons against DeepSeek V4 Pro 0813, Kimi K3, Qwen3.8 Max, GLM 5.3, GPT-5.6, and Claude Opus 5 across search, coding, tool-use, productivity, and security benchmarks. According to the company's own reported figures:

• BrowseComp: 92.5 (vs. 83.4 for DeepSeek V4 Pro, 91.2 for Kimi K3)
• AutomationBench: 53.8 (highest among all listed models)
• BFCL v4 (tool use): 77.0 (highest among all listed models)
• CyberGym: 86.5 (highest among all listed models)
• SWE-bench Pro: 59.6 (below Kimi K3's 61.6 and Claude Opus 5's 74.7)
• Terminal-Bench 2.1: 78.3 (trailing Qwen3.8 Max at 89.3 and Claude Opus 5 at 90.2)

These are the lab's self-reported numbers; none have been independently verified. Atria Dawn Preview leads on several tool-use and search benchmarks but trails competitors, notably Claude Opus 5, on coding-heavy tasks like SWE-bench Pro and Terminal-Bench.

Deployment

The model can be run locally via SGLang (v0.5.13.post1+) or vLLM (v0.23.0+), or accessed through hosted API endpoints in international and China regions. Shanghai AI Lab has also published integration guides for Codex, Claude Code, and Kimi Code, including configuration steps to disable multimodal input handling in client tools that assume image support by default — a necessary step since the model rejects image inputs with a 400 error.

What this means

Atria Dawn Preview is a preview-stage release aimed squarely at agentic workflows — research, coding, office productivity, and security testing — rather than general chat or multimodal use. Built on a 744B-parameter MoE base, it competes directly with frontier-scale models from DeepSeek, Moonshot (Kimi), Alibaba (Qwen), Zhipu (GLM), OpenAI, and Anthropic on agentic benchmarks. The self-reported scores show strength in tool-calling and browsing tasks but weaker performance on demanding coding benchmarks compared to Claude Opus 5, suggesting the model may be better suited to research and automation pipelines than production software engineering. As a preview release with text-only input, it should be treated as an early checkpoint rather than a finished product — independent verification of the benchmark claims is not yet available.
