fx is now available as a provider in T3 Code
Vercel announced that fx, its open-source coding agent harness, is now available as a built-in provider in T3 Code on web, desktop, and mobile. T3 Code is an open-source control plane for coding agents, and the fx provider supports Supervised and Auto modes along with existing fx models and skills.
Why it matters
