I Built a Full App with Union Alpha + OpenCode (FREE)

Union Alpha + OpenCode built a full app with $0.00 in Union Alpha model usage. I test this new free stealth model on OpenRouter, build an AI thumbnail app and show the results, bugs and fixes.

Then I test the deployed app, fix a login state issue and get it generating a thumbnail. My verdict: a useful free model, around 7/10. The design needs work, the first run had bugs and Stripe billing was not finished. But the thumbnail generator worked after the state fix, and the Union Alpha session showed 143,239 tokens with $0.00 spent. Cost note: Union Alpha inference was free for this test. I also topped up $5 for a separate model used during setup; that was not a Union Alpha charge. Bright Data and other services have their own credits and pricing. Model availability and free offers can change.
