Use OpenAI (ChatGPT) with DeployHermes
Sign in with the ChatGPT account you already pay for, and your agents run on that plan. There is no API key to create or paste.

What you bring
Sign-in: A ChatGPT account. DeployHermes does not resell or mark up the usage.
Set it up
- Open AI providers in your workspace.
- Under Add a provider, find OpenAI (ChatGPT) and choose Sign in.
- Open the link we show you in a new tab, sign in, and enter the code when asked.
- Keep the page open. It updates itself the moment you approve.
- Choose each agent's model in Squad. Each connection stays independent, so adding one provider never replaces another.
Note: Your workspace server sleeps when idle. Initial server setup takes about 1 min; sign‑in is available once it is ready. If the code expires before you approve, start again for a new one.
Note: OpenAI bills and limits usage on your ChatGPT plan, not DeployHermes. Heavy use can hit your plan's limits.
Questions
01Do I need an API key for ChatGPT?
No. The plan sign-in in step 2 is all you need.

02Is a ChatGPT plan the same as OpenAI API billing?
No. The OpenAI API platform is billed separately from a ChatGPT plan. This guide uses the plan sign-in, so nothing is billed to an API account.

03What if I hit my plan limits?
OpenAI limits usage on your ChatGPT plan, not DeployHermes, so heavy use can reach those limits. Check your plan before you add a large squad.
