Local 30B AI agent debugs C raytracer using screenshot feedback

By PulseAugur Editorial · [1 sources] ·

A developer has demonstrated how a local 30B parameter model, Codehamr, can debug a raytraced FPS demo written in C by using headless screenshot loops. This method allows the agent to visually inspect the results of its actions, such as firing a rocket and capturing the frame at impact, to identify and correct errors. While a frontier model like Claude Code on Opus 4.8 also completed the task, the developer was particularly impressed by the local Qwen3.6 27B agent's ability to debug the raytracer by analyzing its own screenshots, suggesting that providing agents with visual feedback can enable them to tackle more complex problems.
