}

Available on crate feature anthropic only.

Configuration for Anthropic API.

Example

use adk_model::anthropic::{AnthropicConfig, ThinkingMode, Effort};

// Opus 4.7 with adaptive thinking and xhigh effort (recommended)
let config = AnthropicConfig::new("sk-ant-xxx", "claude-opus-4-7")
    .with_thinking_mode(ThinkingMode::Adaptive)
    .with_effort(Effort::XHigh);

// Adaptive thinking with medium effort (recommended for Sonnet 4.6)
let config = AnthropicConfig::new("sk-ant-xxx", "claude-sonnet-4-6")
    .with_thinking_mode(ThinkingMode::Adaptive)
    .with_effort(Effort::Medium);

// Budget-based thinking (legacy, rejected on Opus 4.7)
let config = AnthropicConfig::new("sk-ant-xxx", "claude-sonnet-4-5")
    .with_thinking_mode(ThinkingMode::Enabled { budget_tokens: 8192 });

// Prompt caching (enabled by default, can be disabled)
let config = AnthropicConfig::new("sk-ant-xxx", "claude-sonnet-4-6")
    .with_prompt_caching(false); // opt out

Fields

api_key: String

Anthropic API key.

model: String

Model name (e.g., "claude-opus-5", "claude-sonnet-5").

max_tokens: u32

Maximum tokens to generate.

base_url: Option<String>

Optional custom base URL (for proxies, Ollama, Vercel Gateway, etc.).

prompt_caching: bool

Enable prompt caching with cache_control blocks.

Defaults to true. Anthropic prompt caching reduces costs and latency by reusing previously processed context. Disable with with_prompt_caching(false).

thinking: Option<ThinkingMode>

Thinking mode configuration.

effort: Option<Effort>

Effort level (goes into output_config.effort). Works with or without thinking enabled.

fast_mode: bool

Enable fast mode for Claude Opus 5 or Claude Opus 4.8 (research preview). Delivers up to 2.5× higher output tokens/sec at premium pricing.

citations: bool

Enable citations on documents in requests.

inference_geo: Option<String>

Geographic routing for data residency (e.g., "US", "EU").

context_management: Option<ContextManagement>

Server-side context management (tool result clearing, thinking block clearing). Requires beta header (auto-injected by adk-anthropic).

service_tier: Option<String>

Service tier ("auto" or "standard_only").

beta_features: Vec<String>

Beta feature headers (e.g., "prompt-caching-2024-07-31").

api_version: Option<String>

Custom API version header override.

tool_search: Option<ToolSearchConfig>

Tool search configuration for regex-based dynamic tool discovery. When set, only tools whose names match the regex pattern are loaded. When None, all available tools are loaded.
