Hugging Face releases Swift Transformers – package to implement transformers APIs in Swift.

Overall, couple of products were released and updated:

• swift-transformers, an in-development Swift package to implement a transformers-like API in Swift focused on text generation. It is an evolution of swift-coreml-transformers with broader goals: Hub integration, arbitrary tokenizer support, and pluggable models.
• swift-chat, a simple app demonstrating how to use the package.
• An updated version of exporters, a Core ML conversion package for transformers models.
• An updated version of transformers-to-coreml, a no-code Core ML conversion tool built on exporters.
• Some converted models, such as Llama 2 7B or Falcon 7B, ready for use with these text generation tools.

Package currently supports following models:

• Llama 2;
• Falcon;
• StarCoder models, based on a variant of the GPT architecture;
• GPT family, including GPT2, distilgpt, GPT-NeoX, GPT-J.

As of now package is in active development. It is not expected to be used in production projects without appropriate testing.
