Nex AGI: DeepSeek V3.1 Nex N1
Analysis Summary
Nex AGI's DeepSeek V3.1 Nex N1 is a text model with a 131K context window, tool use, and function calling. Its supplied results include an intelligence index of 21.4, a math index of 49.7, and comparatively strong GPQA and MMLU Pro results. Coding-related test results and long-context data are also present, although no coding index is provided.
This profile makes it a candidate for cost-conscious analytical workflows, structured problem solving, and tool-connected tasks that do not require image input. Its measured intelligence remains well below leading models, and businesses should validate instruction following and tool reliability on real tasks. It is not a suitable default for high-stakes work without a review process.
At $0.135 per million input tokens and $0.50 per million output tokens, it offers a low-cost route to tested reasoning capability. Pilot it on bounded work before expanding usage.
