OpenAI makes ‘Sign in with ChatGPT’ a way to use your subscription in third-party developer tools
OpenAI has announced that it is making it easier for ChatGPT subscribers to use their allowance inside third-party AI and coding tools, The New Stack reports. The mechanism described in the source is 'Sign in with ChatGPT,' which the outlet characterizes as a way to use your subscription in third-party developer tools. The excerpt states that the change is intended to let ChatGPT subscribers apply their allowance within AI and coding tools made by other companies, rather than only inside OpenAI's own surfaces. The source text available is brief and does not name specific third-party tools, list supported integrations, give a rollout date, or describe pricing or allowance mechanics beyond the phrase 'use their allowance.' It also does not state which subscription tiers are eligible or how usage is metered across third-party tools. The post was published on The New Stack and carries a 2026-09-29 timestamp. No benchmark figures, model version numbers, or monetary values appear in the provided excerpt, so none are reported here. The only concrete product name present is ChatGPT, tied to the 'Sign in with ChatGPT' sign-in flow.
Developers using third-party AI and coding tools may be able to apply their existing ChatGPT subscription allowance there, per the source.
