GPT-4o Audio Preview (2025-06-03)

We’ve added the new gpt-4o-audio-preview-2025-06-03 model from OpenAI to Vellum.

Edit Test Cases in a Resizable Side Drawer

We’ve updated the Evaluation Report table to make editing Test Cases smoother and more intuitive.

Side Drawer for Editing

Click on any editable cell to open a right-side drawer where you can:

• Edit variable values and row details
• Switch between “Values” and “Details” tabs
• Save or reset your changes
• Navigate between rows with Next/Previous buttons

Cleaner, Focused UI

Editing is now more spacious and organized with resizable drawer and inputs—no more cramped inline inputs.

Better Keyboard & Focus Handling

Fields auto-focus when selected, and scroll into view with enhanced keyboard shortcuts:

• ⌘ + S (or Ctrl + S) – Save current edits
• ⌘ + ↑ / ⌘ + ↓ (or Ctrl + arrow) – Move to previous/next row

This update makes it easier to view and edit full Test Cases—especially helpful when working with complex inputs or many variables.

Updated Deployment Flow

We’ve redesigned the Deployment Flow for Prompt and Workflow Sandboxes to provide a cleaner, more intuitive experience. The Create and Update Deployment forms have been streamlined with improved organization and clearer visual hierarchy.

Additionally, the Releases tab in the Deployment Details page has been redesigned for better usability and visual clarity, making it easier to manage Release Tags and track Deployment history.

Condensed Node View

You can now enable Condensed Node View from the Navigation Settings to streamline your workflow interface. This feature displays all Nodes in a more compact format, significantly reducing visual clutter and making it easier to navigate complex workflows with many Nodes.

This is particularly useful when working with large, multi-step workflows where the standard Node view can become overwhelming. The condensed view helps you maintain a clear overview of your entire workflow structure while still preserving full functionality—simply click on any Node to expand it and make changes as needed.

Deployment Release Descriptions

You can now add descriptions to your Prompt and Workflow Deployments during the Deployment process. This new feature allows you to document the purpose, changes, or context for each Deployment directly within the platform.

When creating a new Deployment, you’ll see an optional description field where you can provide details about what this specific Deployment includes, why it was created, or any other relevant information for your team.

Once deployed, the Release Description will be visible in the Deployment Details page, providing valuable context about what changed in each release.

This feature helps teams maintain better documentation of their Deployment history and understand the evolution of their Prompts and Workflows. Coming soon: You will also be able to add and edit descriptions after a Deployment has been created.

Prompt & Workflow Descriptions

You can now specify a description for a Prompt or Workflow. To add a description, click on “Edit Details” from within the More Menu.

This will open a modal where you can edit the Prompt/Workflow’s label as well as description.

Upon specifying a description, an info icon will appear where you and others can hover over to see a tooltip explaining what the Prompt/Workflow is intended to do. Descriptions are also shown in the List View of Prompt/Workflow index pages.

Specifying descriptions can serve as a helpful reminder for what the Prompt or Workflow is meant to do, as well as provide documentation for others on your team.
