Vincent

Vincent is a copilot for data scientists that can perform multiple actions within Jupyter Notebooks, including generating, running, editing, and deleting cells.

Vincent autonomously breaks down high-level tasks into steps, reasons based on outputs (including visual ones), and proceeds until the task is complete.

Multi-step Actions

To complete a task, Vincent performs several steps. Every step has an associated plan (like a thought) and action related to a specific cell.

You can see the steps breakdown by clicking the “Steps” toggle in the chat.

Interaction Modes

There are 3 main ways to use Vincent:

Agent Mode

In this mode, you can give Vincent higher-level tasks. It will complete the task by taking multiple actions on the notebook like adding new cells and editing existing ones.

Chat Mode

Ask Vincent questions in the sidebar and get instant answers. Use it for brainstorming, planning tasks, and getting answers about your notebook. In Chat Mode, Vincent will not take any action on your notebook.

Edit Cells

Select a cell (or number of cells) by clicking on the cell number (or by pressing cmd+M inside the cell) and describe what you want to change. Vincent will iteratively edit and run the cell until finished. In this mode Vincent will not edit ar add any other cells.

Additional Features

Review Changes

After Vincent has completed a task, you can review the changes he made to the notebook by clicking on the "Review Changes" at the bottom of the last message to see the notebook diff from the beginning of the task.

You can also review changes of a specific step from the start by clicking on the review button in a specific step.

Edit Steps

You can edit Vincent’s steps to get it to do what you want. This is often easier than following up in the chat. To do that, click on the edit icon for a specific step and save. When you edit a step, it will automatically revert the notebook to that checkpoint and run from there.

To see the code diff of a specific step, click on the action, like 'Overwrite Cell', and a diff view will open up in a new pane.

Automatic Error Correction

When Vincent runs a cell and gets an error, it will fix it automatically. When you run a cell manually and get an error - clicking the cell will prompt a Fix Error button in the chat.

Custom Instructions

Custom Instructions allow you to set persistent guidelines that apply to all notebooks. For example:

• Use Plotly instead of Matplotlib for plotting.
• Follow PEP 8 coding guidelines.

These instructions become part of the context, so you don’t need to repeat them every time. Edit custom instructions via the personalization button on the top of the sidebar, next to the restart session button.
