# Gemini 3 Flash Preview

> Google's Gemini 3 Flash Preview via Gemini API. Fast and capable text generation.

Gemini 3 Flash Preview is Google's fast language model, available through Anyfast via the native Gemini API. Designed for responsive, high-throughput applications requiring 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
* **Balanced performance** — Strong capabilities at faster speeds

## Quick example

<CodeGroup>
  ```bash cURL theme={null}
  curl "https://www.anyfast.ai/v1beta/models/gemini-3-flash-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-flash-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"])
  ```
