## Choose when

### Choose transformers if…

- License: transformers is Apache-2.0, Soul-of-Waifu is GPL-3.0.
- Requirements: Min 4 GB RAM; Works with Python 3.10+ and PyTorch 2.4+.
- Tags unique to transformers: audio, deep-learning, machine-learning, natural-language-processing.
- Also covers Computer Vision, Inference & Serving, Model Training.
- The library excels in scenarios where you need highly optimized and pre-trained models available for a wide range of data types including text, vision, audio, and multimodal inputs.

### Choose Soul-of-Waifu if…

- License: Soul-of-Waifu is GPL-3.0, transformers is Apache-2.0.
- Tags unique to Soul-of-Waifu: ai, ai-companion, ai-girlfriend, ai-roleplay.
- Leaner open-issue backlog (4).

## When NOT to use transformers

- If the specific task or dataset size does not benefit from state-of-the-art models due to computational inefficiency or overfitting, alternatives may be more suitable.
- It might not be the best choice for projects that strictly require compatibility with frameworks other than PyTorch and Python versions older than 3.10.

## When NOT to use Soul-of-Waifu

- LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves.
