## 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 ai-gateway if…

- ai-gateway is primarily Go; transformers is Python.
- Tags unique to ai-gateway: ai-gateway, ai-infrastructure, guardrails, litellm.
- ai-gateway ships Docker support for self-hosted deployment.

### Choose transformers if…

- transformers is primarily Python; ai-gateway is Go.
- 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 Model Training, Speech & Audio.
- 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 ai-gateway

- Inference & Serving: Self-hosting rarely beats a hosted API on cost until you have steady, high-volume traffic.
- LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves.

## 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.
