# Gemini 3.5 Flash-Lite

> Use Google Gemini 3.5 Flash-Lite through the native Gemini API for high-throughput agents, document parsing, and structured extraction.

Gemini 3.5 Flash-Lite is Google's fastest and lowest-cost model in the Gemini 3.5 family. It is designed for high-throughput subagent execution, document parsing, data extraction, routing, and classification through the native Gemini API.

## Key capabilities

* **1M token context** - Up to 1,048,576 input tokens and 65,536 output tokens
* **Multimodal input** - Text, image, video, audio, and PDF input; text output
* **High throughput** - Optimized for latency-sensitive document parsing and bulk extraction
* **Subagents** - Improved tool reliability for code execution, search, and multi-step workflows
* **Structured extraction** - Strong document understanding, tabular processing, and JSON output
* **Tools** - Function calling, code execution, File Search, Google Search, Google Maps, URL context, and structured output
* **Thinking** - `minimal` by default; use `medium` or `high` for autonomous tool use and multi-step reasoning

## Quick example

<CodeGroup>
  ```bash cURL theme={null}
  curl "https://www.anyfast.ai/v1beta/models/gemini-3.5-flash-lite:generateContent?key=YOUR_API_KEY" \
    -H "Content-Type: application/json" \
    -d '{
      "contents": [
        {
          "role": "user",
          "parts": [{ "text": "Extract the invoice number, date, and total as JSON." }]
        }
      ],
      "generationConfig": {
        "thinkingConfig": {
          "thinkingLevel": "minimal"
        },
        "responseMimeType": "application/json",
        "maxOutputTokens": 1024
      }
    }'
  ```

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

  response = requests.post(
      "https://www.anyfast.ai/v1beta/models/gemini-3.5-flash-lite:generateContent",
      params={"key": "YOUR_API_KEY"},
      json={
          "contents": [{
              "role": "user",
              "parts": [{"text": "Extract the invoice number, date, and total as JSON."}],
          }],
          "generationConfig": {
              "thinkingConfig": {"thinkingLevel": "minimal"},
              "responseMimeType": "application/json",
              "maxOutputTokens": 1024,
          },
      },
  )
  response.raise_for_status()
  print(response.json()["candidates"][0]["content"]["parts"][0]["text"])
  ```
</CodeGroup>

## API changes

<Warning>
  Do not send `temperature`, `topP`, or `topK`. Google has deprecated these sampling parameters for Gemini 3.6 Flash and Gemini 3.5 Flash-Lite. Also remove `candidateCount` and legacy `thinkingBudget` configurations.
</Warning>

Requests must not end with a non-empty `model` role turn. End the conversation with a non-empty `user` turn; otherwise the API returns HTTP 400.
