Devin now runs on your ChatGPT plan: connect Go, Plus, or Pro and spend plan quota inside Devin

#What happened

On October 9, 2026, Cognition announced on X that Devin users can now "use any personal ChatGPT plan with Devin": connect a Go, Plus, or Pro plan to Devin, and all GPT model usage will draw down from the plan's quota. OpenAI Codex product lead Thibault Sottiaux (@thsottiaux) reshared the announcement the same day, writing: "Your ChatGPT subscription is now also a Devin subscription."

This builds on the September 29 DevDay launch of "Sign in with ChatGPT," the official feature that lets paid ChatGPT subscribers sign in to third-party apps and run AI requests on their plan's included usage. OpenAI launched it with 16 partners including Cognition's Devin, Notion, Vercel, T3, OpenClaw, and Dactyl.

#Why it matters

Devin Pro and Max cost $20 and $200 a month, and customers who hit Devin usage limits previously had to buy extra credits to keep agents running. Cognition's announcement means founders already paying for a ChatGPT plan can stretch that same subscription across both services, drawing agent work from quota they already pay for. For lean teams watching AI bills, that is the practical win: one subscription now covers both the chat tool and the coding agent.
