Nex-AGI (Shanghai Innovation Institute) open-sourced Nex-N2.6, a 321B multimodal agentic model (FP8 weights) built on GLM-5.3-Flash, supporting text, image and video input for computer use, coding, and long-horizon tool-driven tasks.
Key numbers vs. Nex-N2.5-Pro: reasoning repetition fell from 16.0% to 1.6% (a 90% relative reduction), non-repetition rate up to 97.8%; 100% valid tool selection across 956 tested contexts, on par with GPT-6-Sol; scores 83.0 on OSWorld and 84.1 on Terminal-Bench 2.1, ahead of DeepSeek-V4.1-Flash (71.7 / 82.7).
Available on GitHub, Hugging Face, OpenRouter API and MOSS API.
