Struct AnthropicModel 

pub struct AnthropicModel { /* private fields */ }

Native Anthropic Messages API adapter.

Signed thinking blocks are kept and replayed to Anthropic on later turns, and dropped automatically when the conversation is sent to another provider.

Implementations

impl AnthropicModel

pub fn new(model: impl Into<String>, api_key: impl Into<String>) -> Self

pub fn with_base_url(self, url: impl Into<String>) -> Self

pub fn with_prompt_caching(self, on: bool) -> Self

Cache the system prompt and tool definitions (on by default). Agent loops resend them every step, so this cuts cost and latency sharply.

pub fn with_pricing(self, pricing: Pricing) -> Self

Trait Implementations

impl Model for AnthropicModel

fn id(&self) -> String

Identifier such as anthropic:claude-opus-5-5.

fn complete<'life0, 'life1, 'async_trait>( &'life0 self, request: &'life1 ModelRequest, ) -> Pin<Box<dyn Future<Output = Result<ModelResponse, ModelError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

fn stream<'life0, 'life1, 'async_trait>( &'life0 self, request: &'life1 ModelRequest, ) -> Pin<Box<dyn Future<Output = Result<ModelStream, ModelError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Stream the response as it is generated. The stream always ends with StreamEvent::Completed carrying the full response. The default implementation calls Model::complete and replays it as deltas.

fn pricing(&self) -> Option<Pricing>

Prices for this model, if configured. Required for USD budgets.

fn cost_usd(&self, response: &ModelResponse) -> Option<f64>

Cost of a response in USD, if pricing is configured.

fn max_call_cost(&self, input_tokens: u64, output_tokens: u64) -> Option<f64>

Upper bound in USD for one call with this many input and output tokens, counting every attempt a composite model might make. Input is priced at the higher of the input and cache-write rates.

fn unpriced_models(&self) -> Vec<String>

Ids of models (including any inside a composite) that have no pricing. A USD budget cannot be enforced while this is non-empty.
