DOS AI

Fast, affordable AI inference for open-source models.

DOS AI is an inference platform that lets you run leading open-source language models through a simple, OpenAI-compatible API. No GPU management, no infrastructure headaches -- just an API key and a few lines of code.

Why DOS AI?

• OpenAI-compatible -- Swap your base URL and you're done. Works with the OpenAI Python SDK, Node.js SDK, LangChain, LlamaIndex, and any HTTP client.
• Low latency -- Models served on dedicated GPUs with optimized inference (vLLM). No cold starts, no queues.
• Pay-as-you-go -- Only pay for the tokens you use. Every new account gets $5 in free credits to get started.
• Open-source models -- Access the best open-source models without managing your own infrastructure.

Quick start

Get up and running in under a minute:

from openai import OpenAI

client = OpenAI(
    base_url="https://api.dos.ai/v1",
    api_key="dos_sk_...",  # Get your key at app.dos.ai
)

response = client.chat.completions.create(
    model="dos-ai",
    messages=[
        {"role": "user", "content": "Explain quantum computing in one paragraph."}
    ],
)

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