Struct AnthropicConfig 

pub struct AnthropicConfig {
    pub api_key: Option<String>,
    pub base_url: String,
    pub default_model: String,
    pub max_context_tokens: usize,
    pub retry_policy: RetryPolicy,
    pub enable_prompt_caching: bool,
    pub cache_ttl: String,
}

Configuration for Anthropic Claude models.

Claude models support prompt caching for significant cost savings (90% on cache reads). Enable caching for static system prompts and context that doesn’t change often.

Example

use multi_llm::AnthropicConfig;

let config = AnthropicConfig {
    api_key: Some("sk-ant-api03-...".to_string()),
    default_model: "claude-3-5-sonnet-20241022".to_string(),
    enable_prompt_caching: true,
    cache_ttl: "1h".to_string(),  // 1-hour cache
    ..Default::default()
};

Environment Variables

• ANTHROPIC_API_KEY: API key (required)

Models

• claude-3-5-sonnet-20241022: Latest Sonnet (recommended)
• claude-3-opus-20240229: Most capable
• claude-3-haiku-20240307: Fastest, cheapest

Fields

api_key: Option<String>

Anthropic API key (starts with “sk-ant-”).

base_url: String

Base URL for API requests (default: https://api.anthropic.com).

default_model: String

Default model to use for requests.

max_context_tokens: usize

Maximum context window size in tokens (200K for Claude 3).

retry_policy: RetryPolicy

Retry policy for transient failures.

enable_prompt_caching: bool

Enable prompt caching for cost savings.

When enabled, static system prompts and context are cached, reducing costs by 90% on cache reads.

cache_ttl: String

Cache TTL setting: “5m” for 5-minute cache, “1h” for 1-hour cache.

• “5m”: Ephemeral cache, 1.25x write cost, good for development
• “1h”: Extended cache, 2x write cost, good for production
