Transformer Lab is an open-source desktop application (built with Electron and Python) that provides a unified GUI for training, fine-tuning, evaluating, and chatting with large language models and diffusion models. It runs locally on Apple Silicon, Linux, and Windows (WSL2), and scales to GPU clusters for team use.

Use cases

• fine-tune an LLM with LoRA on my local machine
• train and evaluate models without writing code
• run RLHF experiments on open models
• chat with and benchmark local LLMs
• fine-tune diffusion models like Stable Diffusion
• scale model training from a laptop to a GPU cluster
• private local environment for experimenting with transformers

When to choose

• you want a GUI for the full LLM experiment loop (train, evaluate, chat) without stitching together scripts
• you work on Apple Silicon and want MLX support
• you need local, private experimentation with no cloud costs
• you want to move from local hardware to shared GPU clusters with the same tool

When to avoid

• you need a headless, scriptable training pipeline for CI/CD
• you only want inference serving in production rather than research experimentation
• you require permissive licensing for embedding in closed-source products (AGPL-3.0)
• you need multi-node distributed training at frontier scale
