Azure Functions shipped a serverless agents runtime in public preview at Build 2026. Agents are defined in .agent
Microsoft's Azure Functions has introduced a public preview of its serverless agents runtime, allowing developers to define agent logic using `.agent` files. This move democratizes the creation of specialized AI agents, abstracting away much of the underlying infrastructure complexity.
This development is significant because it lowers the barrier to entry for building agent-based AI applications within the Azure ecosystem. Companies can now more easily integrate custom AI capabilities into their serverless workflows, potentially impacting industries reliant on task automation and intelligent processing. It signifies a broader trend towards more accessible and modular AI development tools.
Future developments will likely focus on the agent definition language's capabilities and the breadth of integrations Azure Functions will support. Observing the adoption rate and the emergence of specific agent use cases, particularly in comparison to competitors like AWS Lambda's plans for similar functionalities, will be crucial in assessing its long-term impact.
