# Gemini 3.1 Flash Lite Preview

> Google's Gemini 3.1 Flash Lite Preview via Gemini API. Fast and efficient text generation.

Gemini 3.1 Flash Lite Preview is Google's lightweight and efficient language model, available through Anyfast via the native Gemini API. Optimized for speed and cost-effectiveness while maintaining strong language understanding.

## Key capabilities

* **Native Gemini API** — Uses Google's native API format for full feature access
* **Fast inference** — Optimized for low-latency responses
* **Multi-turn conversations** — Handles complex dialogue with system instructions
* **Cost-efficient** — Lightweight model suitable for high-throughput applications

## Quick example

<CodeGroup>
  ```bash cURL theme={null}
  curl "https://www.anyfast.ai/v1beta/models/gemini-3.1-flash-lite-preview:generateContent?key=YOUR_API_KEY" \
    -H "Content-Type: application/json" \
    -d '{
      "contents": [
        {
          "role": "user",
          "parts": [{ "text": "Explain quantum computing in simple terms." }]
        }
      ],
      "generationConfig": {
        "temperature": 1,
        "topP": 1
      }
    }'
  ```

  ```python Python theme={null}
  import requests

  url = "https://www.anyfast.ai/v1beta/models/gemini-3.1-flash-lite-preview:generateContent"
  params = {"key": "YOUR_API_KEY"}
  data = {
      "contents": [
          {
              "role": "user",
              "parts": [{"text": "Explain quantum computing in simple terms."}]
          }
      ],
      "generationConfig": {
          "temperature": 1,
          "topP": 1
      }
  }

  response = requests.post(url, params=params, json=data)
  result = response.json()
  print(result["candidates"][0]["content"]["parts"][0]["text"])
