Designed for lightweight agentic workflows, it focuses on computer use, web browsing, and visually grounded tasks while maintaining strong performance in coding benchmarks. ## Key Specifications - **Release Date**: September 8, 2026 - **Parameters**: Not specified in available sources - **Architecture**: Text-generation model (based on pipeline_tag) - **License**: Apache 2.0 - **Context Length**: Not specified in README - **Access**: - Hugging Face: [https://huggingface.co/nex-agi/Nex-N2.5-mini](https://huggingface.co/nex-agi/Nex-N2.5-mini) - OpenRouter (free tier): [https://openrouter.ai/nex-agi/nex-n2.5-mini](https://openrouter.ai/nex-agi/nex-n2.5-mini) - Docker: nexagi/sglang:v0.5.18-nex-patch ## Performance Analysis ### Coding Benchmarks Nex-N2.5-mini shows solid coding performance, though it trails the larger variants and top competitors: - Terminal-Bench 2.1: 73.4% (vs 89.1% for Claude Opus 5) - SWE-Bench Pro: 43.8% (vs 79.2% for Claude Opus 5) - DeepSWE v1.1: 36.1% (vs 73.7% for Claude Opus 5) ### Agentic Workflows The model demonstrates capable agentic performance for its size: - AutomationBench v1.0.6: 32.3% (vs 50.3% for Claude Opus 5) - Toolathlon Verified: 54.6% (vs 76.5% for Claude Opus 5 and Kimi-K3) - Job Bench: 28.5% (vs 65.7% for Claude Opus 5) - BrowseComp: 83.4% (strong web browsing capability) ### Computer Use Strong performance in computer use tasks: - OSWorld-Verified: 71.2% (vs 86.1% for Qwen3.8-Max) - WebArena-Verified: 63.4% (vs 71.6% for Kimi-K3) - Vision2Web: 52.9% (vs 79.8% for GPT-5.6 Sol) ## Pricing and Accessibility - **OpenRouter**: Available for free usage (rate limits may apply) - **Hugging Face**: Weights available under Apache 2.0 license - **Self-hosted**: Docker image provided (nexagi/sglang:v0.5.18-nex-patch) - **No official per-token pricing published** - free access suggests community/research focus ## Use Case Recommendations Choose Nex-N2.5-mini if: - You need a free, open-source agentic model - Your use case involves light computer use or web automation - You're experimenting with agentic workflows and want zero-cost entry - You prefer self-hosting with Docker for data privacy Consider alternatives if: - You need maximum agentic performance (consider Claude Opus 5 or Nex-N2.5-Max) - You require strong multimodal vision capabilities - You have high-volume production needs (free tier may have limits) ## Verdict The Nex-N2.5-mini represents a solid entry point into the Nex-N2.5 agentic family, offering capable performance for lightweight agentic tasks at zero cost. While it doesn't match the top-tier performance of Claude Opus 5 or the larger Nex-N2.5 variants, its free availability and strong showing in computer use benchmarks (particularly BrowseComp at 83.4%) make it an attractive option for developers exploring agentic workflows without financial commitment. The Apache 2.0 license and Docker deployment option further enhance its appeal for experimentation and privacy-sensitive applications. ## Sources - Model card: [https://huggingface.co/nex-agi/Nex-N2.5-mini](https://huggingface.co/nex-agi/Nex-N2.5-mini) - README: [https://huggingface.co/nex-agi/Nex-N2.5-mini/resolve/main/README.md](https://huggingface.co/nex-agi/Nex-N2.5-mini/resolve/main/README.md) - Benchmark data: Extracted from model card tables - OpenRouter listing: [https://openrouter.ai/nex-agi/nex-n2.5-mini](https://openrouter.ai/nex-agi/nex-n2.5-mini)
