Highlights
- Full spectrum model matrix: From 8B to 671B parameters, the Nex series covers everything from edge-friendly setups to frontier-scale deployments.
- Agent-focused performance: Demonstrates industry-leading results on programming, tool-use, web-search, and other multi-hop reasoning tasks.
- Production-ready utility: Excels at mini-app development, website authoring, slide creation, and immersive role-play—delivering immediate productivity
gains.
- End-to-end control: Developers can build the entire data-to-deployment loop on top of Nex, ensuring sovereignty while keeping costs predictable.
- Open ecosystem: Turnkey synthetic data pipelines, curated datasets, Nex-N1 checkpoints, the NexAU Agent framework, the EaaS MoE inference stack, and NexRL
training services are all openly available.
Nex-N1 is evaluated on six representative agentic benchmarks (general + professional). The model consistently ranks at or near the top across tool-using, web-search, and coding-heavy evaluations, showing strong readiness for real-world agent workflows.

Nex-N1 provides various size models from 8B to 671B for different usage scenarios.
Nex-N1 demonstrates competitive performance across all evaluation scenarios, showing particularly strong results in practical coding and HTML generation tasks.

Usage
Local Deployment
We recommend sglang for serving Nex-series models locally:
python -m sglang.launch_server --model-path /path/to/your/model
Function Calling
Nex-series models support robust function-calling capabilities. To maximize the function-calling capabilities of the Nex-series models, we modified the tool parser of qwen3_coder, see: https://github.com/sgl-project/sglang/pull/13411. To enable this feature, simply add the --tool-call-parser qwen3_coder flag when launching the server:
python -m sglang.launch_server --model-path /path/to/your/model --tool-call-parser qwen3_coder
Mini Program Development
Nex-N1 is optimized for mini program development. For optimal performance, we recommend using Claude Code configured with both context7 and a search MCP.
claude mcp add --transport http context7 https://mcp.context7.com/mcp --header "CONTEXT7_API_KEY: [CONTEXT7_API_KEY]" claude mcp add --transport stdio serper-search --env SERPER_API_KEY=[SERPER_API_KEY] -- npx -y serper-search-scrape-mcp-server
