Agents, Workers - Introducing the Agents SDK

We've released the Agents SDK, a package and set of tools that help you build and ship AI Agents. You can get up and running with a chat-based AI Agent (and deploy it to Workers) that uses the Agents SDK, tool calling, and state syncing with a React-based front-end by running the following command: npm create cloudflare@latest agents-starter -- --template="cloudflare/agents-starter" # open up README.md and follow the instructions You can also add an Agent to any existing Workers applicati

Workers AI - Workers AI now supports structured JSON outputs.

Workers AI now supports structured JSON outputs with JSON mode, which allows you to request a structured output response when interacting with AI models. This makes it much easier to retrieve structured data from your AI models, and avoids the (error prone!) need to parse large unstructured text responses to extract your data. JSON mode in Workers AI is compatible with the OpenAI SDK's structured outputs response_format API, which can be used directly in a Worker: JavaScript import { OpenA

Workflows - Concurrent Workflow instances limits increased.

Workflows now supports up to 4,500 concurrent (running) instances, up from the previous limit of 100. This limit will continue to increase during the Workflows open beta. This increase applies to all users on the Workers Paid plan, and takes effect immediately. Review the Workflows limits documentation and/or dive into the get started guide to start building on Workflows.
