Kaito Baba (@kAIto47802) added constraint handling for multi-objective optimization by GPSampler, a Gaussian process-based Bayesian optimization. It is especially beneficial when many expensive metrics need to be considered. Learn more in our article: medium.com/optuna/optuna-…
We recently published an arXiv article about a sample-efficient black-box combinatorial optimization for TPE by considering distance structures of categorical parameters. This feature is available via categorical_distance_func in TPESampler. arxiv.org/abs/2507.08053
Optuna v4.5 has been released! ⛏️GPSampler for constrained multi-objective optimization 🚀Significant speedup of TPESampler and plot_hypervolume_history 🦾CmaEsSampler now supports 1D search space 🐍The optunahub library is published on conda-forge github.com/optuna/optuna/…
Optuna v4.4 is now available as of June 16! This release introduces the Optuna MCP Server, our first LLM-based toolchain. We're already hard at work on Optuna v5, following our roadmap. For full details, check out our blog post. medium.com/optuna/announc…

Kaito Baba (@kAIto47802) implemented constrained optimization for GPSampler, a Gaussian process-based Bayesian optimization! This allows handling constraints such as the maximum possible neural network size. Check out our article! medium.com/optuna/optuna-…
🚀 In Optuna v4.1, major optimizations were made to speed up RDBStorage up to 63%. Check out our latest blog post for details! 🔗 medium.com/optuna/optunas…
Difan Deng at @AutoML_org, the world-leading AutoML institute, integrated SMAC3, a SOTA Bayesian optimization algorithm, into OptunaHub! Check out the article to learn how to use it from OptunaHub: medium.com/optuna/smac3-r…
Optuna 4.2.1 patch just released. This release includes a bug fix addressing an issue where Optuna was unable to import if an older version of the grpcio package was installed. github.com/optuna/optuna/…
