 # Anthropic Provider
 
-<Callout>The Anthropic provider does not support tool calling yet.</Callout>
+<Callout>The Anthropic API does not support streaming tool calls yet.</Callout>
 
 The Anthropic provider contains language model support for the [Anthropic Messages API](https://docs.anthropic.com/claude/reference/messages_post).
