You don't need to install anything to do your first inference. You only need your access token. DeepInfra gives you access to 100+ open-source models at the best prices available.

Step 1: Get your API key

Go to the Dashboard and create an API key. If you're logged in, examples throughout the docs will have your token pre-filled.

Step 2: Make your first API call

curl "https://api.deepinfra.com/v1/openai/chat/completions" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $DEEPINFRA_TOKEN" \
  -d '{
      "model": "deepseek-ai/DeepSeek-V3",
      "messages": [
        {
          "role": "user",
          "content": "Hello!"
        }
      ]
    }'
from openai import OpenAI

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

response = client.chat.completions.create(
    model="deepseek-ai/DeepSeek-V3",
    messages=[{"role": "user", "content": "Hello!"}],
)
print(response.choices[0].message.content)
import OpenAI from "openai";

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

const response = await openai.chat.completions.create({
  model: "deepseek-ai/DeepSeek-V3",
  messages: [{ role: "user", content: "Hello!" }],
});
console.log(response.choices[0].message.content);

The response looks like this:

{
    "id": "chatcmpl-guMTxWgpFf",
    "object": "chat.completion",
    "created": 1694623155,
    "model": "deepseek-ai/DeepSeek-V3",
    "choices": [
        {
            "index": 0,
            "message": {
                "role": "assistant",
                "content": "Hello! It's nice to meet you. Is there something I can help you with?"
            },
            "finish_reason": "stop"
        }
    ],
    "usage": {
        "prompt_tokens": 15,
        "completion_tokens": 16,
        "total_tokens": 31,
        "estimated_cost": 0.0000268
    }
}

That's it

You're using the OpenAI Chat Completions API — the same interface you already know. The only changes are:

  • Base URL: https://api.deepinfra.com/v1/openai
  • API key: your DeepInfra token
  • Model: any model from our catalog

The official OpenAI Python and Node.js libraries work out of the box.

Install the SDK (optional)

pip install openai
npm install openai
