Honest assessment
Strengths & Weaknesses
↑ Strengths
↓ Weaknesses
The tool is designed for small parameter models (26M) and may not perform well or efficiently with larger datasets.
Given its niche focus, the user base and available resources are limited compared to more established frameworks like Hugging Face Transformers.
The official documentation primarily covers basic setup and usage but lacks detailed guides on fine-tuning, hyperparameter optimization, and custom configurations.
Setting up the environment requires a good understanding of Python dependencies and virtual environments which can be challenging for beginners.
