OpenAI
Connect OpenAI models to AgentOne with your API key.
OpenAI is the maker of the GPT model family. AgentOne includes OpenAI as a built-in provider, so all you need is an API key.
Getting an OpenAI API Key
Sign in to OpenAI
Go to platform.openai.com and sign in or create an account.
Open the API Keys page
In the left sidebar, click API keys, then click Create new secret key. Give it a name you will recognize (for example, "AgentOne").
Copy the Key
OpenAI shows the key only once. Copy it immediately and keep it somewhere safe - you cannot view it again after closing the dialog.
Billing required
OpenAI requires a funded account or active subscription to use API keys. The playground and API are separate from a ChatGPT subscription - you may need to add credits at platform.openai.com/settings/organization/billing.
Connecting OpenAI in AgentOne
Open Provider Settings
In AgentOne, click Settings -> Providers.
Find and Enable OpenAI
Under Built-in Providers, locate OpenAI, expand it, and toggle the enable switch on.
Paste Your Key
Paste your API key into the API Key field and click the save button.
Once saved, OpenAI models such as GPT-4o appear in the model selector in chat.
Available Models
AgentOne's built-in model list includes the major GPT-4o and o-series models. If OpenAI releases a new model that is not yet in the list, you can add it manually using Add Model Override. See Built-in Providers for how.
Troubleshooting
- 401 Unauthorized: the API key is wrong or was not saved. Re-paste and save again.
- 429 Too Many Requests / quota error: you have hit your usage limit. Check billing at platform.openai.com.
- Model not showing: confirm the provider is enabled and has at least one model entry.
