# Gemini 2.5 Flash Lite

> Google's Gemini 2.5 Flash Lite via Gemini API. Lightweight and cost-efficient text generation.

Gemini 2.5 Flash Lite is Google's most efficient language model in the 2.5 series, available through Anyfast via the native Gemini API. Ideal for lightweight tasks requiring fast responses at minimal cost.

## Key capabilities

* **Native Gemini API** — Uses Google's native API format for full feature access
* **Ultra-efficient** — Lowest latency and cost in the Gemini 2.5 family
* **Multi-turn conversations** — Handles dialogue with system instructions
* **High throughput** — Suitable for large-scale, cost-sensitive workloads

## Quick example

<CodeGroup>
  ```bash cURL theme={null}
  curl "https://www.anyfast.ai/v1beta/models/gemini-2.5-flash-lite: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-2.5-flash-lite: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"])
  ```
