The signal is the ceiling: Measurement limits of LLM-predicted experience ratings from open-ended survey text

Researchers tested whether prompt engineering or model selection better improves LLM accuracy on fan experience ratings from baseball survey text. Prompt tweaks yielded only 2 percentage points of gain (67% to 69% accuracy), while GPT-5.2 and GPT-4.1-mini both underperformed the baseline, suggesting diminishing returns on optimization.

Micro Language Models Enable Instant Responses

Researchers developed micro language models (8M–30M parameters) that generate the first few words of responses directly on edge devices like smartwatches, while cloud models complete the sentence—eliminating multi-second latency gaps. The approach matches performance of 70M–256M parameter models while enabling genuinely responsive on-device AI.
