Runway now works inside ChatGPT on GPT-6 Astra: brief it, let it generate, give notes, all in one chat window
Runway's new ChatGPT plugin lets GPT-6 Astra brief and revise while Runway's models render, but every generation spends Runway credits and Astra in Chat is limited to Pro, Business and Enterprise plans.
Runway launched a plugin for ChatGPT on Oct 7, built around OpenAI's GPT-6 Astra. You install it from the plugins directory, pick Astra and mention Runway in the chat; Astra writes the brief, reads your product link or reference image and takes your notes, while Runway's models generate the images and video in the same conversation.
The plugin costs nothing to install, but every generation spends your Runway credits, so you still need a Runway account and a plan that covers the models you ask for. Seedance 2.5, Kling 3.0, Veo 3.1 and Gen-4.5 are on Runway's list, and Astra can choose one for you.
Access is narrower than the launch film suggests. OpenAI's help center puts Astra in Chat on Pro, Business and Enterprise, gives Plus users Astra in Work and Codex instead, and enterprise admins have to switch it on.
In practice, the director's chair moves into the chat window and the video model becomes a service the assistant calls, so the brief and the notes you write there now matter as much as the model you pick.
