# Latest Gemini models

Build with Google's latest models for reasoning, coding, and native media generation through one unified API. Start with `gemini-4-hydrogen` for fast, dependable coding, agentic workflows, and multimodal knowledge work. Use `gemini-4-carbon` or `gemini-4-argon` for deep frontier reasoning, or pick a specialized model below.

## Compare Gemini models  {% class="hide-from-toc" id="compare-models" %}

Every Gemini model below accepts text, images, audio, video, and PDFs. All four models support [Google Search grounding](/docs/google-search), [code execution](/docs/code-execution), [function calling](/docs/function-calling), [computer use](/docs/computer-use), and [structured outputs](/docs/structured-output).

## Quickstart  {% class="hide-from-toc" id="quickstart" %}

Send your first request using the Google GenAI SDK and the [Interactions API](/docs/interactions-overview). Swap `model` to test any tier.

{% tabs %}
  {% tab filename="quickstart.py" label="Python" %}
  ```python
  from google import genai
  
  client = genai.Client()
  
  interaction = client.interactions.create(
      model="gemini-4-carbon",
      input="Explain gravity to a skeptical cat in three short sentences.",
  )
  
  print(interaction.output_text)
  ```

  {% /tab %}

  {% tab filename="quickstart.js" label="JavaScript" %}
  ```javascript
  import { GoogleGenAI } from "@google/genai";
  
  const client = new GoogleGenAI({});
  
  const interaction = await client.interactions.create({
    model: "gemini-4-carbon",
    input: "Explain gravity to a skeptical cat in three short sentences.",
  });
  
  console.log(interaction.output_text);
  ```

  {% /tab %}

  {% tab label="REST" %}
  ```bash
  curl -X POST "https://generativelanguage.googleapis.com/v1beta/interactions" \
    -H "x-goog-api-key: $GEMINI_API_KEY" \
    -H "Content-Type: application/json" \
    -d '{
      "model": "gemini-4-carbon",
      "input": "Explain gravity to a skeptical cat in three short sentences."
    }'
  ```

  {% /tab %}

{% /tabs %}

## Set up your coding agent  {% class="hide-from-toc" id="coding-agents" %}

Give your coding agent live access to the latest Gemini models, SDK syntax, and documentation so it always builds with up-to-date information.

```bash
# Connect the live Gemini Docs MCP server
npx add-mcp "https://gemini-api-docs-mcp.dev"

# Install official Gemini API agent skills
npx skills add google-gemini/gemini-skills --skill gemini-api-dev --global

# Or install the bundled Antigravity plugin
agy plugin install https://github.com/google-gemini/gemini-skills
```

You can also append `.md` to any documentation URL or feed [`llms.txt`](https://aistudio.google.com/llms.txt) to your agent. See [Coding agent setup](/docs/coding-agents) for editor configs and `AGENTS.md` templates.

## Specialized models  {% class="hide-from-toc" id="specialized-models" %}

Beyond the general-purpose and media models above, the Gemini API includes specialized endpoints:

* **[Managed Agents](/docs/agents):** [`antigravity-preview-09-2026`](/docs/antigravity-agent) for coding and tool orchestration, and [`deep-research-preview-04-2026`](/docs/deep-research) for autonomous multi-step research.
* **[Decisions](/docs/decisions-api):** [`gemini-decision-1`](/docs/models/gemini-decision-1) for fast, calibrated multimodal yes/no, choice, and rubric score decisions with zero output tokens.
* **[Embeddings](/docs/embeddings):** [`gemini-embedding-2`](/docs/models/gemini-embedding-2) for multimodal text, image, audio, video, and PDF search and RAG.
* **[Music generation](/docs/music-generation):** [`lyria-3.5`](/docs/models/lyria-3.5) for studio-grade instrumental and vocal tracks.
* **[Robotics](/docs/robotics-overview):** [`gemini-robotics-er-2-preview`](/docs/models/gemini-robotics-er-2-preview) for spatial reasoning and embodied planning.

## What's next  {% class="hide-from-toc" id="whats-next" %}

* Browse the full endpoint catalog on [All models](/docs/models).
* Tune reasoning depth and latency in the [Thinking guide](/docs/thinking).
* Review [Pricing](/docs/pricing), [Rate limits](/docs/rate-limits), [Context caching](/docs/caching), and [Batch API (50% cost reduction)](/docs/batch-api).
* Check sunset dates on [Deprecations](/docs/deprecations) and recent updates in [Release notes](/docs/changelog).
