## About Weights & Biases with LuumenAI

Ask about training state without leaving the terminal. Luumen connects to Weights & Biases with an API key and reads your ML workspace: list projects under an entity, page through runs with their states and creation times, check sweeps, artifact types, and reports. It also reads automations, Slack and webhook integrations, team membership, and organization details, so you can see who owns what and where alerts land. Read-only — this integration makes no changes in W&B.

## Example tools

- `WEIGHTS_AND_BIASES_GET_CURRENT_VIEWER` — Return the authenticated W&B user, default entity, and team names for connection context.

## Frequently asked questions

### How does LuumenAI connect to Weights & Biases?

Authorize once with API token. Luumen lists the scopes each action needs before you approve the connection, and credentials never appear in the chat.

No. Every one of the 10 tools is read-only, so LuumenAI can answer questions from Weights & Biases but cannot change anything in it. Read actions still follow the configured access and approval policy.

### Is there an audit trail?

Every call to Weights & Biases is recorded with the actor, the input, and the result.
