Pub/Sub - Release notes

April 06, 2026

2026-04-06T00:00:00-07:00

Feature

Pub/Sub now offers the AI Inference Single Method Transform (SMT). This SMT lets you get inferences on Pub/Sub messages from Vertex AI models. The model's inferences are added to each message, making them available for downstream processing along with the original message data.

The change is being rolled out in a phased manner over the rest of the week. For more information, see AI Inference SMT. This feature is generally available.

Feature

You can now use the Pub/Sub remote MCP server to manage Pub/Sub resources. You can create, list, get, update, and delete Pub/Sub topics, subscriptions, and snapshots, as well as publish messages to topics.

This feature is in Preview.
