A tiny GPT model was trained to memorize every fact presented to it, yet it failed to answer any question that required combining two of those facts. The author tested a one-line fix suggested in a recent paper, which only partially resolved the issue. The post highlights the limitations of small language models in integrating multiple pieces of information.

The study examined how undergraduate English learners perceive feedback from large language models that incorporate process-aware data such as intermediate drafts and keystroke records. Forty‑three participants completed a timed essay, received LLM‑generated feedback based on the final draft, intermediate snapshots, and interaction logs, and then rated the feedback on six Likert items and answered open‑ended questions. Ratings were largely positive, with 74.4%–95.3% of participants giving 4 or 5 stars, and qualitative analysis revealed that most learners found the feedback accurate, though some noted misinterpretations or time constraints.
