Overview

• ϕ-Decoding is a new method that enhances large language model (LLM) text generation
• Balances exploration (trying diverse options) and exploitation (choosing likely outcomes)
• Uses adaptive "foresight sampling" to look ahead in the decision tree
• Achieves higher quality outputs than existing methods like beam search
• Reduces computational costs while maintaining or improving text quality
• Works across different LLM architectures (encoder-decoder and decoder-only)

Plain English Explanation

Think of a chess player planning their moves. A novice might only think one move ahead, while a grandmaster considers multiple possible futures before deciding. ϕ-Decoding works similarly with language models.

Traditional text generation methods like [beam search](https://aimo...
