What are Guidance and Hugging Face Transformers?

Guidance

Guidance is a programming paradigm from Microsoft for steering language model output with interleaved generation, control flow, and constraints. It can run against locally hosted models to produce reliable structured results.

  • Interleaved generation control
  • Token healing
  • Regex and grammar constraints
  • Works with local models

Hugging Face Transformers

Transformers is a widely used library providing pretrained models for text, vision, audio, and multimodal tasks. It supports running and fine-tuning thousands of open models locally with PyTorch.

  • Thousands of pretrained models
  • Text, vision, audio support
  • Fine-tuning tools
  • Large ecosystem
