H2O LLM Studio: model training GUI. Fine-tunes large language models without code.

In simple English

This tool helps you train artificial intelligence models on your own custom data. You do not need any coding experience to use its visual control panel. It runs on your own computer or server and keeps your data private. It requires a powerful graphics card to work properly. The software is free to use under an open-source licence.

What it is

H2O LLM Studio is a framework and no-code graphical user interface for fine-tuning large language models. It provides tools for dataset preparation, experiment tracking, model evaluation, and direct export to the Hugging Face Hub.

What it is good for

Solo builders who want to adapt an open-source language model for a specific task or domain without writing complex training scripts.

Good
  • Includes a visual web interface for managing training experiments.
  • Supports modern memory-saving techniques like Low-Rank Adaptation and 8-bit training.
  • Allows one-click export of trained models to the Hugging Face Hub.
Watch for
  • Requires a dedicated computer or cloud instance with a recent NVIDIA graphics card and at least 24 GB of memory.
  • Rapid ongoing development can occasionally break backward compatibility between versions.
  • Setup involves installing specific drivers, CUDA toolkits, and Python environment tools.
Replaces

Writing custom PyTorch training scripts and manual experiment tracking.

Works well with

Hugging Face Hub for sharing trained models.
