Use UberLLM with Chatbox

Chatbox adds UberLLM as a provider with the OpenAI API Compatible API mode. It works the same in the desktop and mobile apps.

Prerequisites

An UberLLM account with credit
An API key from Dashboard → Keys (ull_...)
A model id, for example deepseek/deepseek-v4.1-flash

One-click import

With Chatbox installed on the same device, open the Add UberLLM to Chatbox link on the Chatbox setup guide. Chatbox asks you to confirm, then adds UberLLM with three models. The link carries no key: open Settings → Model Provider → UberLLM, paste your key and press Check.

If nothing happens when you click it, use the steps below.

Connect

In Chatbox, open Settings → Model Provider and click Add.
Name: UberLLM. API Mode: OpenAI API Compatible. Confirm.
On the new provider's page:
- API Key: your key
- API Host: https://api.uberllm.dev/v1
- API Path: leave it empty (Chatbox uses /chat/completions)
The Preview line should read https://api.uberllm.dev/v1/chat/completions.
Press Check, then Fetch to load the model list, and keep the models you want.
Start a new chat and choose an UberLLM model at the bottom.

Do not pick OpenAI Responses API Compatible: UberLLM serves chat completions, not the Responses API.

Common errors

What you see	Cause and fix
Check fails, `401`	Key missing, mistyped, or has a space.
`404`	The Preview line is not `https://api.uberllm.dev/v1/chat/completions`. Clear API Path and set API Host again.
Fetch shows nothing	Save the key first, then Fetch. You can also add a model by hand with New and its id from the catalog.
"No such model"	The id needs its maker in front, such as `deepseek/deepseek-v4.1-flash`.
`402` `insufficient_credits`	Balance empty. Add credit under Dashboard → Credits.
