+
+- **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.
