API Parameters

🧠

temperature

Controls randomness in generation (0=deterministic, 1=creative).

{`// Example usage: curl -X POST https://api.gemini.com/v1/complete \ -H "Authorization: Bearer YOUR_API_KEY" \ -H "Content-Type: application/json" \ -d '{"prompt":"Debug this Python code","temperature":0.2}'`}

📏

max_tokens
