DeepSeek-V3.1 is post-trained on the top of DeepSeek-V3.1-Base, which is built upon the original V3 base checkpoint through a two-phase long context extension approach, following the methodology outlined in the original DeepSeek-V3 report. We have expanded our dataset by collecting additional long documents and substantially extending both training phases. The 32K extension phase has been increased 10-fold to 630B tokens, while the 128K extension phase has been extended by 3.3x to 209B tokens. Additionally, DeepSeek-V3.1 is trained using the UE8M0 FP8 scale data format to ensure compatibility with microscaling data formats.

Bria Background Generation allows for efficient swapping of backgrounds in images via text prompts or reference image, delivering realistic and polished results. Trained exclusively on licensed data for safe and risk-free commercial use.

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 = "Bria/replace_background";

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": "Bria/replace_background",
    "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: "Bria/replace_background",
        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="Bria/replace_background",
        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 image=@my_image.jpg  \
    -F ref_images=@my_image.jpg  \
    'https://api.deepinfra.com/v1/inference/Bria/replace_background'
```

which will give you back something similar to:

```json
{
  "images": [
    "data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAEAAAABCAIAAACQd1PeAAAADElEQVQI12PQz3wAAAJDAXkkWn+MAAAAAElFTkSuQmCC"
  ],
  "seed": 0,
  "refined_prompt": null,
  "request_id": null,
  "inference_status": {
    "status": "unknown",
    "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 'Bria/replace_background'  \
    -i image=@my_image.jpg  \
    -i image=@my_image.jpg
```

which will give you back something similar to:

```json
{
  "images": [
    "data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAEAAAABCAIAAACQd1PeAAAADElEQVQI12PQz3wAAAJDAXkkWn+MAAAAAElFTkSuQmCC"
  ],
  "seed": 0,
  "refined_prompt": null,
  "request_id": null,
  "inference_status": {
    "status": "unknown",
    "runtime_ms": 0,
    "cost": 0.0,
    "tokens_generated": 0,
    "tokens_input": 0
  }
}
