//! Basic usage example for the GPT-5 Rust client
//!
//! This example shows the simplest way to use the GPT-5 client
//! Run with: cargo run --example basic_usage

    let api_key =
        std::env::var("OPENAI_API_KEY").expect("Please set OPENAI_API_KEY environment variable");

    let client = Gpt5Client::new(api_key);

    // Simple text generation
    println!("🤖 Asking GPT-5 Nano a simple question...");
    let response = client
