Nex-N2-Pro
nex-agi/nex-n2-pro
Nex-N2-Pro is Nex AGI's open-source agentic reasoning model, post-trained on Qwen3.5-397B-A17B (MoE). Its Agentic Thinking framework unifies reasoning, tool use, and environment execution for complex, long-horizon tasks like agentic coding, software engineering, and deep research. It supports a 256K context, function calling, structured (JSON) output, and image input—scoring 75.3 on Terminal-Bench 2.1 and 80.8 on SWE-Bench Verified.
