AI SDK v7 support in Mastra

Mastra supported AI SDK v7 from the day it was released, June 25, 2026. Since then we’ve continued to support and improve the overall end-to-end developer experience.

AI SDK v7 introduced a new provider spec (LanguageModelV4), a top-level reasoning parameter, and a number of API renames. @mastra/core hides the spec differences behind the Agent API and detects the spec to maintain support for v5, v6, and v7. Upgrading your model providers from @ai-sdk/openai@2.x.x (v6) to @ai-sdk/openai@4.x.x (v7) won’t require any Mastra code changes.

Changes have been made to the following Mastra packages:

• @mastra/core: Handles the runtime, agent definitions, .stream() / .generate() calls, and modelSettings.
• @mastra/ai-sdk: Handles route handlers, stream handlers, and converters that adapt a Mastra agent to useChat, useCompletion, or useObject on the frontend.
