Note

A PlainTextContentBlock existed in langchain-core<1.0.0. Although the name has carried over, the structure has changed significantly. The only shared keys between the old and new versions are type and text, though the type value has changed from 'text' to 'text-plain'.

Note

Title and context are optional fields that may be passed to the model. See Anthropic example.
