Which Should You Pick?

Pick Arcee Trinity-Large-Thinking if...

✓Higher output quality (9 vs 7)
✓Better value for money (9.5/10)
✓More features (8 vs 7)

Teams that need a US-made, Apache 2.0, frontier-tier open-weight model and can either rent multi-GPU infrastructure or pay OpenRouter API pricing at ~$0.90/M output tokens. Particularly valuable for US government, defense, or regulated enterprise contexts where country-of-origin matters for procurement. Also good for agentic reasoning workloads where the ~96% cost savings vs Claude Opus actually changes what you can build.

Pick Windsurf if...

✓Easier to use (8 vs 6)

Developers who want agent-first coding (background + inline) inside a familiar VS Code-based editor, and who value Cognition's Devin integration as a core part of the workflow. The April 2026 redesign makes Windsurf 2.0 a direct alternative to Cursor 3 for this use case.
