# AutoGen - Tune GPT Models

`flaml.autogen` offers a cost-effective hyperparameter optimization technique [EcoOptiGen](https://arxiv.org/abs/2303.04673) for tuning Large Language Models. The research study finds that tuning hyperparameters can significantly improve the utility of them.
Please find documentation about this feature [here](/docs/Use-Cases/Autogen#enhanced-inference).
