Experiments page
List of all experiments launched by the team, sorted in chronological order. Each card contains information about the experiment name, when the experiment was created, total runtime of the experiment, and the best fitness found by the Hive. You can also add tags or notes to the experiment to help organize them.
| Experiment status | Description |
|---|---|
| Completed | The experiment finished successfully or was stopped by the user. |
| Running | The experiment is currently running. |
| Failed | The experiment ran into an unrecoverable failure. |
| Aborted | The experiment was interrupted before it started running. |
| Initializing | The experiment is initializing. |
Overview
The overview provides a high-level summary of the experiment’s progress.
Tracking
The tracking tab is an interactive workspace for exploring how the Hive evolves code over time. The evolution chart plots fitness across iterations — hover over a point to see a summary of what the Hive attempted, or select a point to view the corresponding code on the left.
- Copy — copies the currently selected file to your clipboard.
- Hide chart — hides the evolution chart on the left to have more room to view the code.
- Edit comparison — in comparison mode (see below), click to change whether clicking a new point on the evolution chart selects a new red or green point.
- Download — download a zip of the repo at the currently selected point.
- Show full range — expand viewable range to show all points (by default the y-axis is clipped to show only points better than the initial point).
- Show all points — shows all points (by default, only points which are best-over-time and their ancestors are shown).
- Legend — colour key for the data points.
- Expand — view the chart in full screen.
- Reset — clear any zoom selection.
- Compare — select two points to view the code diff between them.


Iterations
A searchable, filterable table listing every iteration with its status, duration, and timestamp. Useful for auditing specific runs or debugging failed experiments.
| Iteration status | Description |
|---|---|
| Completed | The iteration successfully proposed a new code candidate and evaluated it. |
| Running | The iteration is currently in progress. |
| Cancelled | The iteration was cancelled, usually because the experiment terminated before it completed. |
| Failed | The iteration encountered an error (e.g., the LLM failed to produce valid code, or the evaluation script errored). |

Logs
Logs associated with the experiment. There are three categories of logs:- Setup: Output of the setup script specified in
sandbox.setup_scriptin the configuration YAML. - User: Any output of the evaluator. You can view any outpout which you print in your evaluator script here to aid in debugging.
- System: Logs emitted by the Hive.
- Coordinator: Logs emitted by the Hive itself.
- Sandbox: Logs emitted by the sandboxes where the evaluators are run. By default, only logs for a single sandbox are shown. You can show logs of other sandboxes or every sandbox by clicking the dropdown.

Insights
The home page shows a summary of your team’s experiment activity. Use the time range selector (e.g., 7 days, 1 month, 3 months) to adjust the window at which the data is shown for.
