Known weaknesses

Each one links to the public issue, changelog or docs page it came from, where we have one.

1. 01

   Limited language support

   The tool is primarily built for Python and does not natively support other programming languages, which can be a barrier for developers who prefer or need to use different languages.

2. 02

   Steep learning curve due to specialized knowledge required

   Understanding both PyTorch and the specific nuances of fine-tuning large language models is necessary, which can be challenging for newcomers without a strong background in deep learning.

3. 03

   Performance bottlenecks with very large datasets

   When dealing with extremely large datasets or complex model architectures, the tool may experience performance issues that could slow down the fine-tuning process significantly.

4. 04

   Lack of comprehensive documentation and examples

   The current documentation lacks detailed explanations and practical examples, making it difficult for users to understand how to fully leverage the tool's capabilities without extensive trial and error.

What it does well

• Efficient fine-tuning of large language models using PyTorch.

• Integration with existing PyTorch workflows and tools.

• Optimized for performance and scalability.
