It offers utilities and scripts to streamline the process; pick aikit if aikit is a toolkit designed for fine-tuning, building and deploying large language models (LLMs) with an emphasis on open-source technologies. [SimpleTuner](https://github.com/bghira/SimpleTuner) reports 2.9k GitHub stars, 289 forks, and 5 open issues, last pushed Aug 23, 2026. [aikit](https://kaito-project.github.io/aikit/) has 537 stars, 57 forks, and 40 open issues, last pushed Aug 24, 2026.
