Setting Up Qodo PR-Agent with Abacus AI on GitLab CI

This guide explains how to configure Qodo PR-Agent to use Abacus AI's RouteLLM API for automated code reviews in GitLab merge requests.

The Challenge

Qodo PR-Agent uses litellm for LLM routing. While Abacus AI provides an OpenAI-compatible API, configuring it through litellm's openai provider doesn't work correctly because:

The openai provider prepends openai/ to model names (e.g., openai/gpt-5.1-codex-max)
Abacus AI rejects prefixed model names with "Invalid model" errors

The wiring diagram works exactly the same for the Creality Melzi board

To run the test, replace atmega328p with atmega1284p

	let char = 'C';
	let width = ui.fonts(\|f\| -> f32 {
	f.glyph_width(&TextStyle::Body.resolve(ui.style()), char)
	});
