Connect providers and choose models

Understand the connection#

Configure a provider, then choose the conversation's model in the composer.

Prepare your account#

Open Settings → Providers with the service's credential and endpoint ready. For a Claude CLI account, inspect Settings → Claude CLI.

Onevium sign-in and model access are separate. Put secrets in configuration fields, not chat messages. A generic API endpoint is not automatically compatible: protocol, authentication, and tool support must match.

Make the first connection#

1. Choose a supported provider and fill its required fields.
2. Check the endpoint and authentication method, then save.
3. Open a conversation and select an available model.
4. Send a small request, then try reading a non-sensitive project file.

Reply with one sentence confirming you received this message.
Do not read files or run commands.

Check model selection and usage#

Success means the selected model replies and the file-reading workflow you need works. A text response does not establish support for images or every tool.

Check the model before a long run. Inspect recorded usage in Settings → Usage & billing, and compare unexpected usage with the provider's account information.

Troubleshoot a connection#

• Authentication error: check credentials, authentication method, and account access.
• Model unavailable: check its identifier, account availability, and visibility settings.
• Timeout: check endpoint, network, and proxy configuration.
• Text works but tools fail: inspect compatibility and the actual error.

Use the connection in a project#

Run your first task. See permissions for action controls and settings and data for information boundaries.
