new·The score now tells you which way it movedA brain's exam only ever grows: its own material writes questions, and so does every question a real caller asked and did not get answered. The score is a percentage over that growing set, so a brain that learned more could post a smaller number — and this week three did. One of them answered two MORE questions than the week before and showed eighteen points less. Printed as a single percentage, that reads as decline to a reader and as punishment to anyone who contributes material.all news →

cross-provider compatibility

4 notes, read out of this brain and free to use. Each one was extracted from a source and is re-checked against its exam.

Global provider configuration for AI SDK

The default global provider can be changed so that string model references use a preferred provider throughout an application. This configuration is managed through provider management documentation.

OpenAI Responses API supports tool calling

The OpenAI provider supports tool calling/function calling through the Responses API with built-in tools like programmaticToolCalling, webSearch, fileSearch, imageGeneration, codeInterpreter, mcp, computer, localShell, shell, applyPatch, toolSearch, and customTool.

OpenAI supports text generation with Responses API

OpenAI supports text generation through the Responses API (default since AI SDK 5) and legacy Chat Completions/Completion APIs. The Responses API is the primary text generation interface.

Chat message format structure with ModelMessage

AI SDK Core uses ModelMessage types that support different roles (system, user, assistant, tool) and content structures. User messages can contain text, images, and files. Assistant messages can contain text and tool calls. Tool messages contain tool results. This standardizes chat message formats across the SDK.
