LLM JSON optimization shows mixed results across models

An optimization involving a change in JSON field representation for LLMs showed promising results on the Qwen2.5-7B model, improving correctness on the GSM8K benchmark. However, this optimization failed to translate to the Llama 3.2 3B model, reducing its correctness on the same benchmark and on an executable tool-call task. The findings suggest that while such representation changes can be beneficial for one model, they are not universally portable optimizers and represent a semantic intervention on the model. AI

IMPACT Highlights the challenges in creating portable optimization techniques for LLMs, suggesting that model-specific tuning may be required.
