Program-as-Weights: A Programming Paradigm for Fuzzy Functions

Key point

Proposes a new paradigm that compiles natural language specifications into lightweight neural network artifacts to dramatically lower inference costs.

Details

Existing LLM API call methods suffer from high costs and poor reproducibility. To address this, we propose a new paradigm called Fuzzy-function programming.

Program-as-Weights (PAW) is a method that takes a natural language specification as input and compiles it into an executable, small-scale neural network artifact. A 4B-scale compiler is trained on the FuzzyBench dataset to generate Parameter-Efficient Adapters (PEFT) for a fixed lightweight interpreter.

The key features of this approach are as follows:

  • Efficiency: A 0.6B-scale Qwen3 interpreter achieves the performance of a 32B model, while reducing inference memory usage to 1/50.
  • Speed: Runs at 30 tokens/s on a MacBook M3 environment.
  • Paradigm shift: Redefines the LLM not as a 'problem solver' that processes input every time, but as a 'Tool Builder' that creates reusable tools.
