Model Card
Nex N2 Pro (Free) is an open-source agentic mixture-of-experts language model from Nex AGI, post-trained on top of Qwen3.5-397B-A17B with 17B active parameters out of 397B total, released in June 2026 under an Apache 2.0 license.
Built around an Agentic Thinking framework, the model unifies reasoning, tool use, and environment execution into a single closed loop — covering requirement understanding, task planning, code implementation, debugging, and iterative refinement. It supports function calling, structured outputs, and reasoning traces, and accepts both text and image inputs.
Nex N2 Pro excels at coding, terminal execution, deep research, and long-horizon agentic workflows. Reported benchmarks include 75.3 on Terminal-Bench 2.1 and 90.7 on GPQA Diamond. With a 262K context window and zero cost on the free tier, it is a strong option for developers building agents, coding assistants, or multi-step automation pipelines.
