Model Card
Nex N2 Pro is an agentic mixture-of-experts model from Nex AGI, built on a Qwen3.5 base with 397B total parameters and 17B active per token, released open-source under Apache 2.0 in June 2026.
The model's Agentic Thinking framework closes the loop between planning, code implementation, environmental feedback, and iterative debugging — making it especially capable at long-horizon tasks. It supports function calling, structured outputs, vision inputs, and reasoning traces.
Benchmark highlights include 75.3 on Terminal-Bench 2.1, 80.8 on SWE-Bench Verified, and 90.7 on GPQA Diamond. It is a strong fit for developers building coding agents, deep research pipelines, or multi-step automation that demands reliable tool use and a 262K context window.
