Image Generation

Serika.dev provides a powerful Image Generation API compatible with the OpenAI standard. You can generate high-quality images using various models, including NovelAI and TensorArt.

Endpoint

POST https://api.serika.dev/api/openai/v1/images/generations

[!NOTE] For heavy models (like TensorArt), consider using the Jobs API to avoid timeouts.

Quick Start

from openai import OpenAI

client = OpenAI(
    base_url="https://api.serika.dev/api/openai/v1",
    api_key="your_api_key"
)

response = client.images.generate(
    model="novelai/nai-diffusion-3",
    prompt="A cute anime girl with pink hair, high quality",
    size="1024x1024",
    quality="standard",
    n=1,
)

image_url = response.data[0].url
print(f"Image URL: {image_url}")

import OpenAI from 'openai';

const client = new OpenAI({
  baseURL: 'https://api.serika.dev/api/openai/v1',
  apiKey: 'your_api_key',
});

async function main() {
  const response = await client.images.generate({
    model: "novelai/nai-diffusion-3",
    prompt: "A cute anime girl with pink hair, high quality",
    n: 1,
    size: "1024x1024",
  });

  console.log(response.data[0].url);
}

main();
