Nex-N2 releases two open-source models for AI agents
Nex AGI released Nex-N2-Pro and Nex-N2-mini. Both are open-source models fine-tuned from Qwen3.5. The release says they perform well on benchmarks for agent tasks, coding, tool use, and long tasks. Mini is a 35B model, while Pro is based on a 397B model line.
Key points
- Nex-N2-Pro and Nex-N2-mini were released together.
- Both models are fine-tuned from the Qwen3.5 family.
- The release focuses on agent tasks, coding, and tool use.
- Nex-N2-mini is the smaller 35B option, so it may be useful for cost and speed tests.
- The model card includes setup notes for function calling and a reasoning parser.
