✨ Major Features

Standard content blocks

A new unified API for accessing modern LLM features across all providers:

• New contentBlocks property: Provides provider-agnostic access to reasoning traces, citations, built-in tools (web search, code interpreters, etc.), and other advanced LLM features
• Type-safe: Full TypeScript support with type hints for all content block types
• Backward compatible: Content blocks can be loaded lazily with no breaking changes to existing code

Example:

const response = await model.invoke([
  { role: "user", content: "What is the weather in Tokyo?" },
]);
// Access structured content blocks
for (const block of response.contentBlocks) {
if (block.type === "thinking") {
console.log("Model reasoning:", block.thinking);
} else if (block.type === "text") {
console.log("Response:", block.text);
}
}

For more information, see our guide on content blocks.
