Connect your apps

Almost every AI app has a box for a "base URL" or "custom endpoint". Put the anz33 address in it and that app can reach every engine you own, chosen automatically.

The one setting

http://127.0.0.1:3300/v1

If the app also demands an API key, type anything — local is fine. anz33 does not check keys unless you have deliberately turned that on for household use.

Copy it without typing. The menu-bar or tray app has Copy Endpoint URL. Handy when an app wants it pasted into a small box on a phone-sized window.

Where the setting hides

Kind of app	Look for
Chat clients and desktop AI apps	Settings → Model provider → "OpenAI compatible", then Base URL
Code editors and coding assistants	An "OpenAI compatible" or "custom endpoint" provider, plus a model name
Note-taking apps with AI features	Usually an "AI provider" section with a URL field
Anything with a config file	A key called `base_url`, `api_base`, `openai_api_base` or `endpoint`

Two things worth knowing when an app asks for a model name:

auto is a valid model name. It means "you choose", and it is the right answer most of the time.
Any real model name from anz33 models works, and you do not have to say which engine holds it.

In your own code

Any OpenAI client library works — you are only changing the address it points at.

Python

from openai import OpenAI

client = OpenAI(base_url="http://127.0.0.1:3300/v1", api_key="local")

reply = client.chat.completions.create(
    model="auto",
    messages=[{"role": "user", "content": "Summarise this in one line: ..."}],
)
print(reply.choices[0].message.content)

JavaScript

import OpenAI from "openai";

const client = new OpenAI({
  baseURL: "http://127.0.0.1:3300/v1",
  apiKey: "local",
});

const reply = await client.chat.completions.create({
  model: "auto",
  messages: [{ role: "user", content: "Hello" }],
});

Environment variables

Many tools read these without any code change at all:

export OPENAI_BASE_URL=http://127.0.0.1:3300/v1
export OPENAI_API_KEY=local

Streaming

Streaming — words appearing as they are generated — works exactly as apps expect. Set "stream": true and anz33 passes the stream straight through from the engine.

Other machines on your network

By default anz33 answers only the computer it runs on. To let a phone or a second laptop use the same router:

anz33 serve --lan

Then point the other device at http://<this-computer's-IP>:3300/v1. Before you do, read Sharing with your household — opening the router to your network is exactly when you want profiles and keys turned on.

Checking a connection

If an app cannot see anz33, ask the router directly from the same machine:

curl http://127.0.0.1:3300/v1/models

A list of models means the router is fine and the problem is in the app's settings — most often a missing /v1 at the end of the URL, or https where it should be http.
