Guiding Text Generation with Constrained Beam Search in 🤗 Transformers
This Hugging Face blog post introduces constrained beam search, a text generation technique that allows users to enforce hard constraints on model outputs, such as requiring specific tokens or phrases to appear in generated text. The method extends standard beam search by guiding the search process to satisfy user-defined constraints while still optimizing for fluency. The post covers the implementation available in the Hugging Face Transformers library, making the technique accessible to practitioners.

Generating Human-level Text with Contrastive Search in Transformers
Hugging Face introduces contrastive search, a decoding strategy for autoregressive language models that aims to produce more coherent and human-like text compared to standard methods like beam search or nucleus sampling. The technique works by balancing a model's confidence in its next-token prediction against a contrastive penalty that discourages repetitive or degenerate outputs. The blog post describes integration of contrastive search into the Hugging Face Transformers library, making it accessible to practitioners.
Assisted Generation: a new direction toward low-latency text generation
Hugging Face introduces assisted generation (speculative decoding) as a practical technique for reducing LLM inference latency. The approach uses a smaller draft model to propose token candidates that a larger model then verifies in parallel, enabling multiple tokens to be accepted per forward pass. The blog post explains the mechanism and demonstrates integration into the Hugging Face Transformers library.
