Support for OpenAI’s GPT 5.1 via Vellum

November 13th, 2025

We now support OpenAI’s GPT 5.1 model via Chat Completions and Responses endpoints.

Updated Condensed Nodes

November 13th, 2025

We’ve redesigned Nodes in Workflows with a cleaner, more condensed look that helps you see more of your Workflow at a glance.

  • Simplified Node appearance with less visual bulk
  • Node results now appear in the console organized by timeline, rather than underneath each Node
  • The console automatically highlights the current streaming Node as your Workflow executes left to right
  • You can now see your entire Workflow even when the console is open
  • Improved visual states for running Nodes, outputs, and errors
  • Cleaned up the appearance of connections between Nodes

Generic Private Code Package Repositories

November 13th, 2025

You can now configure generic private code package repositories for Python that support basic authentication. This allows you to pull dependencies from custom PyPI-compatible repositories. You can use these private repositories when using Code Execution Nodes in Workflows and also in Code Metrics.

To add a private repository you can navigate to the Private Package Repository page here. You can also add a repository by clicking the “Add Private Repository button” in the dropdown of the new Repository field when adding a package.

Web Seach Tool support for Anthropic Claude Models

November 12th, 2025

You can now enable the use of Web Search Tools for Anthropic Claude models.

Environment Variables as Metric Inputs

November 11th, 2025

Evaluation Metrics can now reference Environment Variables as inputs. This is useful for custom Metrics that need secret values like API Keys. Previously, you’d reference workspace-level secrets directly.

Web Search Node

November 10th, 2025

You can now add Web Search Node to your Workflows from the Workflow Sandbox UI. Pass in a query and it’ll return the top 5 search results from the internet, including the page title and URL for each result.

This node used the Serp API Integration under-the-hood to actually perform the web search.

Console Improvements

November 10th, 2025

We’ve made several improvements to the console for viewing and debugging Workflow runs.

  • Auto-select streaming Nodes. The console now automatically selects the latest streaming Node as your Workflow executes, making it easier to follow along in real-time.
  • Better timeline view. The timeline view has improved spacing, colors, icons, and loading states for a cleaner debugging experience.
  • Enhanced Subworkflow and Map Node timelines. We’ve improved the timeline display for Subworkflows and Map Node runs to make debugging these complex execution patterns easier.
  • Console in Subworkflows. The console is now available inside Subworkflows, giving you a snapshot of what happened in the last run without leaving the Subworkflow context.
  • Faster Map Node event viewing. Viewing events inside the Map Node after a run is now much faster and smoother.

Agent Builder Audio Notifications

November 8th, 2025

Agent Builder now plays an audio chime when it’s done building your Workflow if you switched to another browser tab or application while waiting.

Evaluating Workflows That Use Integrations

November 8th, 2025

You can now run evaluations for Workflows that use third-party integrations like Notion or Slack. Previously, these evaluations would fail when they tried to invoke an integration. Now they’ll succeed as long as you’ve authenticated with the integrations used in the Workflow.

Environment Variables & Secrets Simplification

November 7th, 2025

We’ve simplified how you manage Environment Variables, Secrets, and API Keys in Workspace Settings.

  • Environment Variables and Secrets are now unified: There’s no longer a distinction between the two. Just create Environment Variables and mark them as secret with a toggle—we’ll handle the secure storage under-the-hood.
  • Consolidated management page: Environments and Workspaces are now managed on a single “Manage” page.
  • Dedicated API Keys page: API Keys now have their own page within Workspace Settings for easier access.

Customizable Workflow Icons

November 5th, 2025

You can now customize the color and icon of your Workflows. Just click the more menu, then Edit Details, and click on the icon shown. We’ll then show the icon on the Workflows homepage, in your AI App, and more.

New Native Integrations

November 1st, 2025

We’ve added support for 14 new native integrations:

You can now connect these integrations directly to your Workflows in Agent Builder, Agent Nodes, or Custom Nodes.
