Frontier-level capabilities
What developers are doing with Union Alpha right now.
Feed it your entire codebase
With a 256K token context window, you can paste a full repository and get coherent multi-file refactoring without losing a single type annotation.
Debug from a screenshot
Paste a broken UI and get back the exact CSS fix. Point it at an architecture diagram for instant analysis.
Automate without glue code
Native tool-calling support plugs into Cursor, Cline, or your custom agent loop without a single adapter.
More than one brain
Behind the scenes, multiple specialized models compete on every request. A consensus layer picks the best answer before you see it.
Proven on real benchmarks
Union Alpha scores 74.2% on SWE-bench Verified and 74.0% on DeepSWE — matching models that charge $50 per million tokens.
Your code stays yours
Prompts and outputs are not used for model training. Zero data retention throughout the free preview period.
