Struct OpenAIConfig 

pub struct OpenAIConfig {
    pub api_key: Option<String>,
    pub base_url: String,
    pub default_model: String,
    pub max_context_tokens: usize,
    pub retry_policy: RetryPolicy,
}

Configuration for OpenAI GPT models.

Supports GPT-4, GPT-3.5, and other OpenAI models. Also works with OpenAI-compatible APIs by changing the base URL.

Example

use multi_llm::OpenAIConfig;

let config = OpenAIConfig {
    api_key: Some("sk-...".to_string()),
    default_model: "gpt-4-turbo-preview".to_string(),
    ..Default::default()
};

Environment Variables

• OPENAI_API_KEY: API key (required)
• OPENAI_BASE_URL: Custom base URL (optional)

Models

• gpt-4-turbo-preview: Latest GPT-4 Turbo (128K context)
• gpt-4: Standard GPT-4 (8K context)
• gpt-3.5-turbo: Fast and affordable (16K context)

Fields

api_key: Option<String>

OpenAI API key (starts with “sk-”).

base_url: String

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

default_model: String

Default model to use for requests.

max_context_tokens: usize

Maximum context window size in tokens.

retry_policy: RetryPolicy

Retry policy for transient failures.
