Strengths & Weaknesses

↑ Strengths

Trains a small GPT model in just 2 hoursmedium

Open-source under Apache-2.0 licensemedium

Self-hosted and easy to integrate into projectsmedium

↓ Weaknesses

Limited scalability for larger modelshigh

The tool is designed for small parameter models (26M) and may not perform well or efficiently with larger datasets.

Small community supportmedium

Given its niche focus, the user base and available resources are limited compared to more established frameworks like Hugging Face Transformers.

Poor documentation for advanced use caseshigh

The official documentation primarily covers basic setup and usage but lacks detailed guides on fine-tuning, hyperparameter optimization, and custom configurations.

Complex setup process for non-expertsmedium

Setting up the environment requires a good understanding of Python dependencies and virtual environments which can be challenging for beginners.
