Anthropic adapter.
This adapter is implemented using the Messages API and structured outputs. For older models that don't support structured outputs, function calling is used.
Params
params argument should be shaped as a Create message request body.
Example
InstructorLite.instruct(%{

model: "claude-sonnet-4-5",
metadata: %{user_id: "3125"}
},
response_model: %{name: :string, age: :integer},
