New health-time-series benchmark shows LLMs lag behind classic ML baselines

The post recommends a paper on benchmarking LLM reasoning over health time series, with several non-obvious findings.
- The work argues that health evals have lagged behind model progress.
- It compares LLMs against SOTA machine-learning baselines, which the author calls the real baseline in these settings because they are cheaper and usually more explainable.
- The benchmark is framed as a “living ecosystem” with standard contribution paths.
- One interesting result mentioned is a reverse correlation between signal frequency and LLM performance.
- The paper also surfaces specific health areas where LLMs underperform.
