--- license: apache-2.0 --- GPTOpt is a black-box optimization assistant that add black-box optimization capabilities to LLMs. The intended use case is currently continuous optimization problems with 10 or fewer parameters. The model is a fine-tune of Llama 3.1 8B Instruct trained via [Unsloth](unsloth.ai). We provide integration and usage guidelines via [OptunaHub](https://hub.optuna.org/). More information about the model is available in our [paper](https://arxiv.org/abs/2510.25404).
