DeepSeek-Prover-V2, an open-source large language model designed for formal theorem proving in Lean 4, with initialization data collected through a recursive theorem proving pipeline powered by DeepSeek-V3. The cold-start training procedure begins by prompting DeepSeek-V3 to decompose complex problems into a series of subgoals. The proofs of resolved subgoals are synthesized into a chain-of-thought process, combined with DeepSeek-V3's step-by-step reasoning, to create an initial cold start for reinforcement learning.

We recommend using our NodeJS client https://github.com/deepinfra/deepinfra-node.

You can install it with

```bash
npm install deepinfra
```

and then

```javascript
import { TextToImage } from "deepinfra";
import { createWriteStream } from "fs";
import { Readable } from "stream";

const DEEPINFRA_API_KEY = "$DEEPINFRA_TOKEN";
const MODEL = "stabilityai/stable-diffusion-2-1";

const main = async () => {
  const model = new TextToImage(MODEL, DEEPINFRA_API_KEY);
  const response = await model.generate({
    prompt: "a burger with a funny hat on the beach",
  });

  const result = await fetch(response.images[0]);

  if (result.ok && result.body) {
    let writer = createWriteStream("image.png");
    Readable.fromWeb(result.body).pipe(writer);
  }
};

main();
```

Look into `image.png` to see the result.



This document provides an overview of the DeepInfra-compatible OpenAI image generation API. It allows users to generate AI-created images based on text prompts using DeepInfra models.



##  Image Generation

```bash
curl https://api.deepinfra.com/v1/openai/images/generations \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $DEEPINFRA_TOKEN" \
  -d '{
    "prompt": "A photo of an astronaut riding a horse on Mars.",
    "size": "1024x1024",
    "model": "stabilityai/stable-diffusion-2-1",
    "n": 1
    }'
```



The API returns a JSON object containing the generated image(s).

## Example Response
```json
{
  "created": 1707000000,
  "data": [
    {
      "revised_prompt": "A photo of an astronaut riding a horse on Mars.",
      "b64_json": "/9j/4AAQS..."
    }
  ]
}
```



You can use the official OpenAI Node.js client to generate images


## Installation
```bash
npm install openai
```

## Code Example
```javascript
import OpenAI from "openai";
import fs from "fs";

const openai = new OpenAI({
  baseURL: "https://api.deepinfra.com/v1/openai",
  apiKey: "$DEEPINFRA_TOKEN",
});

async function generateImage(prompt, outputPath) {
    const response = await openai.images.generate({
        prompt: prompt,
        model: "stabilityai/stable-diffusion-2-1",
        n: 1,
        size: "1024x1024"
    });

    const base64Data = response.data[0].b64_json;
    const imageBuffer = Buffer.from(base64Data, "base64");

    fs.writeFileSync(outputPath, imageBuffer);
    console.log(`Image saved at: ${outputPath}`);
}

generateImage("A photo of an astronaut riding a horse on Mars.", "output.png");
```


You can use the official OpenAI Python client to generate images

## Installation
```bash
pip install openai
```

## Code Example

```python
import openai
import base64

def generate_image(prompt, output_path):
    client = openai.OpenAI(
        base_url="https://api.deepinfra.com/v1/openai",
        api_key="$DEEPINFRA_TOKEN"
    )

    response = client.images.generate(
        prompt=prompt,
        model="stabilityai/stable-diffusion-2-1",
        n=1,
        size="1024x1024",
    )

    base64_data = response.data[0].b64_json
    image_data = base64.b64decode(base64_data)

    with open(output_path, "wb") as file:
        file.write(image_data)

    print(f"Image saved at: {output_path}")

generate_image("A photo of an astronaut riding a horse on Mars.", "output.png")
```


You can use cURL or any other http client to run inferences:

```bash
curl -X POST \
    -H "Authorization: bearer $DEEPINFRA_TOKEN"  \
    -F 'prompt=A photo of an astronaut riding a horse on Mars.'  \
    'https://api.deepinfra.com/v1/inference/stabilityai/stable-diffusion-2-1'
```

which will give you back something similar to:

```json
{
  "images": [
    "data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAEAAAABCAIAAACQd1PeAAAADElEQVQI12PQz3wAAAJDAXkkWn+MAAAAAElFTkSuQmCC"

    "runtime_ms": 0,
    "cost": 0.0,
    "tokens_generated": 0,
    "tokens_input": 0
  }
}

```


You can use our command-line tool [deepctl](/docs/advanced/deepctl) to run
inferences:

```bash
deepctl infer \
    -m 'stabilityai/stable-diffusion-2-1'  \
    -i 'prompt=A photo of an astronaut riding a horse on Mars.'
```

which will give you back something similar to:

```json
