Use your ChatGPT subscription inside Railway
Railway now lets you connect your ChatGPT subscription and set GPT-6 Astra, GPT-6.1 Sol or GPT-6 Luna as the default model for the Railway Agent, its Discord and Slack bots, and "railway code". It is enabled through Railway's Priority Boarding program.
Why it matters
You can use the ChatGPT plan you already pay for to power Railway's agent instead of a separate API bill.
Who it's for
Developers who deploy on Railway.
How to try it
- In Railway, join Priority Boarding.
- Connect your ChatGPT account and pick a default model.
- Ask the Railway Agent to deploy or debug a service using that model.
Plan & availability: Railway Priority Boarding program with a connected ChatGPT account.
