v0 let ChatGPT Plus and Pro subscribers build on their ChatGPT plan instead of v0 credits

On September 29, 2026, Vercel's v0 let ChatGPT Plus and Pro subscribers connect their subscription, so eligible AI responses from supported OpenAI models counted against the ChatGPT plan, while v0 credits were also needed for platform fees.

On September 29, 2026, Vercel's v0 added support for building with a ChatGPT Plus or Pro subscription, according to the v0 changelog entry on using a ChatGPT subscription in v0. Once a subscriber enabled it, eligible AI responses counted toward the ChatGPT plan instead of v0 credits.

What changed in v0

Supported models were GPT-6 Astra, GPT-5.6 Sol and GPT-5.6 Luna at Standard speed. Fast mode required v0 credits.
Users kept a v0 credit balance for a small platform fee on each AI request, image generation and editing, delegated subagents and other supporting agent work.
Usage through the ChatGPT subscription was subject to the plan's limits, which users could view through Manage usage in ChatGPT.
If the ChatGPT limit was reached, v0 paused generation and saved progress. It did not switch AI responses to v0 credits automatically.

What it meant for people who build with AI

People could build in v0 on a ChatGPT subscription they already paid for, which shifted most generation cost off v0 credits. Credits also covered platform fees and some work, and because v0 paused at the ChatGPT limit instead of falling back to credits, the plan's limits set how far a session could go on the subscription.

How to connect

Users connected through the credit balance menu (Use ChatGPT plan, then Continue with ChatGPT) and approved subscription sharing. The header then showed ChatGPT, and the model picker showed Using ChatGPT plan. Users could switch back to v0 credits from the credit menu at any time.
