union alpha vs kimi k3 tested both models with same prompt at highest reasoning available > union alpha took 30 minutes to make this > k3 took 10 minutes to make this stealth model looks on par with Kimi, it could actually be the kimi next mode can't do more tests now as it's almost unusable right now so gonna try again in morning for now here's output, which one did better?

This post quotes another post: “Union Alpha keeps erroring on OpenCode and OpenRouter, one user says”
