# Enterprise LLM Endpoint

> A dedicated, OpenAI-compatible LLM endpoint for one model at a fixed enterprise price. Use any OpenAI SDK by changing only the base URL and API key.

An Enterprise LLM Endpoint gives your team one large language model behind a private API key, at a fixed enterprise price. The endpoint is **OpenAI-compatible**: any OpenAI SDK, framework, or tool works when you change the base URL and the API key.

<Info>
  Your plan is set to **one model**. The server always uses that model, whatever value you send in `model`. The response's `model` field shows the model that answered.
</Info>

## Quick start

| Setting  | Value                                                          |
| -------- | -------------------------------------------------------------- |
| Base URL | `https://modelslab.com/api/v1/enterprise/proxy/v1`             |
| API key  | Your enterprise API key, sent as `Authorization: Bearer <key>` |
| Model    | Any value. The server uses your plan's model                   |

  ```python Python theme={"theme":{"light":"github-light","dark":"github-dark"}}
  from openai import OpenAI

  client = OpenAI(
      base_url="https://modelslab.com/api/v1/enterprise/proxy/v1",
      api_key="YOUR_ENTERPRISE_API_KEY",
  )

  response = client.chat.completions.create(
      model="default",
      messages=[{"role": "user", "content": "Write a haiku about GPUs."}],
  )
  print(response.choices[0].message.content)
  ```

  ```javascript Node.js theme={"theme":{"light":"github-light","dark":"github-dark"}}
  import OpenAI from "openai";

  const client = new OpenAI({
    baseURL: "https://modelslab.com/api/v1/enterprise/proxy/v1",
    apiKey: "YOUR_ENTERPRISE_API_KEY",
  });

  const response = await client.chat.completions.create({
    model: "default",
    messages: [{ role: "user", content: "Write a haiku about GPUs." }],
  });
  console.log(response.choices[0].message.content);
  ```

  ```bash cURL theme={"theme":{"light":"github-light","dark":"github-dark"}}
  curl https://modelslab.com/api/v1/enterprise/proxy/v1/chat/completions \
    -H "Authorization: Bearer $ENTERPRISE_API_KEY" \
    -H "Content-Type: application/json" \
    -d '{
      "model": "default",
      "messages": [{"role": "user", "content": "Write a haiku about GPUs."}]
    }'
  ```

## What you get

* **The full request body passes through.** Streaming, tools and function calling, structured output (`response_format`), reasoning settings, and prompt caching (`cache_control`) all work as the model supports them.
* **Files, images and PDFs** in the messages, as a URL or base64. See [Files, Images and PDFs](/enterprise-api/llm-endpoint/files).
* **Streaming** with `"stream": true` returns Server-Sent Events as the model generates tokens.
* **Usage in every response.** The `usage` object reports prompt, completion, and cached tokens.
* **A fixed price.** Your enterprise plan sets the price. You do not pay per token.

## What you cannot change

* **The model.** The server replaces `model` with your plan's model. It also removes the fields that pick other models (`models`, `route`) and saved presets (`preset`).
* **The endpoints.** By default the endpoint accepts `chat/completions`, `completions`, and `models`. Other paths return `404`.

## Limits

* A request that is **not streamed** must finish in about **110 seconds**. For long outputs, set `"stream": true`.
* A request can be at most **30 MB**, including files sent as base64.
* A trial plan stops at its expiry date. After that, requests return `403`. See [Errors](/enterprise-api/llm-endpoint/errors).
