A recursive self-improving AI agent that automatically builds AI models

Ranked on PostTrainBench

Ranked at IOAI 2025

AIBuildAI is a recursive self-improving AI agent that automatically builds AI models. Given a task, it runs an agent loop that analyzes the problem, designs models, writes code to implement them, trains them, tunes hyperparameters, evaluates model performance, and iteratively improves the models. By automating the model development workflow, AIBuildAI reduces much of the manual effort required to build AI models.
