## Choose when

### Choose goptuna if…

- goptuna is primarily Go; optuna is Python.
- Pricing: Freely available on GitHub with no associated financial costs due to its open-source nature..
- Requirements: Min 1 GB RAM.
- Tags unique to goptuna: bandit-algorithms, bayesian-optimization, blackbox-optimization, evolution-strategies.
- When you prefer using the Go programming language and require a robust hyperparameter tuning solution that aligns with the performance characteristics of Go applications

### Choose optuna if…

- optuna is primarily Python; goptuna is Go.
- Tags unique to optuna: distributed, hyperparameter-optimization, machine-learning, parallel.
- When you need to streamline the hyperparameter tuning process for machine learning models built in Python.

## When NOT to use goptuna

- If your team lacks proficiency in the Go language, as leveraging Goptuna requires familiarity with Go for efficient code integration and maintenance
- If you require a multi-language support feature widely available among other hyperparameter optimization frameworks, since Goptuna is strictly designed for use within projects using Go

## When NOT to use optuna

- If your project is not compatible with Python, as Optuna does not support other languages directly out of box.
- Projects requiring manual control over every aspect of hyperparameter tuning might find Optuna too automated for their needs.
