Weights & Biases in the terminal
Weights & Biases tracks machine learning experiments, and its Weave product traces AI applications. Connected to a workspace, GBrain can answer “which run had the best validation loss?”, dig into a failing trace, or write up results as a report.
Install takes a W&B API key.
- Analyze experiment runs
- Read Weave traces
- Compare evaluations
- Write reports
Install the CLI, then connect Weights & Biases
Weights & Biases takes a key, pasted in the browser and kept encrypted on GBrain's servers. A key or a sign-in never passes through the terminal.
# Install the CLI curl -sSL https://gbrainio.terminalwire.sh | bash # Set the terminal up and connect it gbrainio terminal connect # What Weights & Biases is, and each of its commands once it is connected gbrainio tool help weights-and-biases
The installer is a shell script for macOS and Linux. Read it before you run it.
Weights & Biases's commands come from Weights & Biases's own server once it is connected, so none are listed here.
Same tools, any AI
Claude Code, Cursor and Codex reach the same Weights & Biases through MCP, on the same permission and the same record.
How the whole thing fits
One level per application, one daily limit, one record, across every AI and terminal that asks.
