## Decision facts: transformers

- **Requirements:** Min 4 GB RAM; Works with Python 3.10+ and PyTorch 2.4+
- **Adopt for:** Transformers is a versatile library for training and deploying state-of-the-art models across various domains such as NLP, computer vision, speech recognition, and multi-modal tasks. It supports PyTorch 2.4+ and Python 3
- **License detail:** Transformers is distributed under the Apache-2.0 license, ensuring wide permissions for use in both open-source and proprietary systems.

## Choose when

### Choose long-context-attention if…

- Tags unique to long-context-attention: ring-attention, llm-inference, llm-training, attention-is-all-you-need.
- Leaner open-issue backlog (12).

### Choose transformers if…

- Requirements: Min 4 GB RAM; Works with Python 3.10+ and PyTorch 2.4+.
- Tags unique to transformers: pretrained models, deep-learning, machine-learning, natural-language-processing.
- Also covers Speech & Audio, Computer Vision.
- 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.

## When NOT to use long-context-attention

- LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves.
- Model Training: Try prompting and RAG first; fine-tuning is the answer to style/format, not missing knowledge.
- Inference & Serving: Self-hosting rarely beats a hosted API on cost until you have steady, high-volume traffic.

## 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.
