Code Examples

The AINative API is fully OpenAI-compatible. If you already use the OpenAI SDK, just change the base URL and model name.

Python

OpenAI SDK (drop-in replacement)

from openai import OpenAI

client = OpenAI(
    api_key="ain_...",  # Your AINative API key
    base_url="https://api.ainative.studio/v1",
)

response = client.chat.completions.create(
    model="meta/llama-3.3-70b-instruct",
    messages=[
        {"role": "system", "content": "You are a helpful assistant."},
        {"role": "user", "content": "Explain quantum entanglement simply."},
    ],
    max_tokens=512,
)

print(response.choices[0].message.content)
JavaScript

Node.js / TypeScript

import OpenAI from 'openai';

const client = new OpenAI({
  apiKey: 'ain_...',
  baseURL: 'https://api.ainative.studio/v1',
});

const response = await client.chat.completions.create({
  model: 'mistralai/mistral-7b-instruct',
  messages: [
    { role: 'user', content: 'What are the best practices for API design?' },
  ],
  stream: true,
});

for await (const chunk of response) {
  process.stdout.write(chunk.choices[0]?.delta?.content ?? '');
}
curl
