Use when the user asks for Gemini chat, streaming completions, multimodal vision input, Google Search grounding, structured output, reasoning effort, or to point an existing OpenAI-compatible or Gemini-native client at RunAPI as the base URL.

# Gemini on RunAPI

Gemini on RunAPI exposes **two protocols**:

| Protocol | Endpoint | Use when |
|---|---|---|
| OpenAI-compatible | `POST /v1beta/openai/chat/completions` | You already use the OpenAI SDK or any OpenAI client |
| Native Gemini | `POST /v1beta/models/<model>:streamGenerateContent` | You use Google's `@google/generative-ai` SDK (currently `gemini-3-flash-preview` only) |

Both accept the same RunAPI API Key.

## Setup

```dotenv
RUNAPI_TOKEN=YOUR_RUNAPI_TOKEN
```

Get a RunAPI API Key at <https://runapi.ai/api_keys>.

### OpenAI-compatible setup

```python
from openai import OpenAI

client = OpenAI(
    api_key="YOUR_RUNAPI_TOKEN",
    base_url="https://runapi.ai/v1beta/openai",
)
```

```typescript
import OpenAI from "openai";

const client = new OpenAI({
  apiKey: "YOUR_RUNAPI_TOKEN",
  baseURL: "https://runapi.ai/v1beta/openai",
});
```

### Native Gemini setup

```bash
export GOOGLE_API_KEY=YOUR_RUNAPI_TOKEN
export GOOGLE_GENAI_BASE_URL=https://runapi.ai
```

## Core recipe — OpenAI-compatible

```python
response = client.chat.completions.create(
    model="gemini-2.5-flash",
    messages=[{"role": "user", "content": "Explain quantum computing simply."}],
    reasoning_effort="high",
)
print(response.choices[0].message.content)
print(response.usage)
```

```typescript
const response = await client.chat.completions.create({
  model: "gemini-2.5-flash",
  messages: [{ role: "user", content: "Explain quantum computing simply." }],
});
```

```bash
curl -X POST "https://runapi.ai/v1beta/openai/chat/completions" \
  -H "x-api-key: YOUR_RUNAPI_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "gemini-2.5-flash",
    "messages": [{"role": "user", "content": "Explain quantum computing simply."}]
  }'
```

## Core recipe — native Gemini

```bash
curl -X POST \
  "https://runapi.ai/v1beta/models/gemini-3-flash-preview:streamGenerateContent" \
  -H "x-goog-api-key: YOUR_RUNAPI_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "contents": [
      { "role": "user", "parts": [{ "text": "Hello!" }] }
    ]
  }'
```

The native protocol returns SSE chunks in Google's `streamGenerateContent`
format — use the official `@google/generative-ai` SDK or Google's
`google-genai` Python package to consume it.

## Streaming (OpenAI-compatible)

```python
stream = client.chat.completions.create(
    model="gemini-2.5-flash",
    messages=[{"role": "user", "content": "Write a haiku about coding."}],
    stream=True,
)
for chunk in stream:
    delta = chunk.choices[0].delta.content
    if delta:
        print(delta, end="", flush=True)
```

Streaming runs through a regional edge proxy so the request does not hold a
Rails/Puma thread. Long generations should always stream.

## Vision / multimodal

```json
{
  "model": "gemini-2.5-flash",
  "messages": [
    {
      "role": "user",
      "content": [
        { "type": "text", "text": "What is in this image?" },
        { "type": "image_url", "image_url": { "url": "https://example.com/img.jpg" } }
      ]
    }
  ]
}
```

Standard OpenAI multimodal block for the OpenAI-compatible endpoint. For the
native endpoint, embed image data as `parts[].inlineData` or `parts[].fileData`.

## Google Search grounding

```json
{
  "model": "gemini-2.5-pro",
  "messages": [
    { "role": "user", "content": "Latest news on Gemini 3." }
  ],
  "tools": [
    { "type": "function", "function": { "name": "googleSearch" } }
  ]
}
```

Available on `gemini-2.5-flash`, `gemini-2.5-pro`, `gemini-3.1-pro-preview`,
and `gemini-3-pro-preview`.

## Structured output

```json
{
  "model": "gemini-2.5-flash",
  "messages": [{ "role": "user", "content": "Give me one person object." }],
  "response_format": {
    "type": "json_schema",
    "json_schema": {
      "name": "person",
      "schema": {
        "type": "object",
        "properties": { "name": { "type": "string" }, "age": { "type": "integer" } },
        "required": ["name", "age"]
      }
    }
  }
}
```

## Reasoning effort

Supported on `gemini-2.5-pro`, `gemini-3.1-pro-preview`, `gemini-3-pro-preview`,
and `gemini-3-flash-preview` — pass `reasoning_effort: "low" | "medium" | "high"`.

## List models

```bash
curl https://runapi.ai/v1beta/models -H "x-api-key: YOUR_RUNAPI_TOKEN"
```

Or via the OpenAI-style path:

```bash
curl https://runapi.ai/v1beta/openai/models \
  -H "Authorization: Bearer YOUR_RUNAPI_TOKEN"
```

## Supported models

| Model ID | OpenAI endpoint | Native endpoint | Capabilities |
|---|---|---|---|
| `gemini-2.5-flash` | yes | — | Chat, multimodal, Google Search, structured output, thoughts |
| `gemini-2.5-pro` | yes | — | + reasoning effort |
| `gemini-3.1-pro-preview` | yes | — | + reasoning effort |
| `gemini-3-pro-preview` | yes | — | + reasoning effort |
| `gemini-3-flash-preview` | yes | `:streamGenerateContent` | Chat, multimodal, function calling, structured output, reasoning effort |

`gemini-flash-latest` resolves to `gemini-3-flash-preview`.

## Connect Gemini CLI itself

```bash
export GOOGLE_API_KEY=YOUR_RUNAPI_TOKEN
export GOOGLE_GENAI_BASE_URL=https://runapi.ai
gemini
```

## Agent rules

- The native `:streamGenerateContent` path is currently only wired for
  `gemini-3-flash-preview` — use the OpenAI-compatible endpoint for every
  other Gemini model.
- Use streaming for any response longer than a few hundred tokens. Do not
  hold the agent on a long blocking request.
- Google Search grounding uses a `googleSearch` function tool.
- Pricing, rate limits, quotas — link to <https://runapi.ai/models/gemini.md>,
  not this skill file.
