During my 10 years teaching 16 to 19 year old we constantly heard we should teach current industry skills, such as Flash actionscript and Dreamweaver.

We preferred to teach more generic skills such as programming principles and HTML. I think we made the right decision.

LLMs Encode How Difficult Problems Are

LLMs Encode How Difficult Problems Are

Large language models exhibit a puzzling inconsistency: they solve complex problems yet frequently fail on seemingly simpler ones. We investigate whether LLMs internally encode problem difficulty in a way that aligns with human judgment, and whether this representation tracks generalization during reinforcement learning post-training. We train linear probes across layers and token positions on 60 models, evaluating on mathematical and coding subsets of Easy2HardBench. We find that human-labeled difficulty is strongly linearly decodable (AMC: $ρ\approx 0.88$) and exhibits clear model-size scaling, whereas LLM-derived difficulty is substantially weaker and scales poorly. Steering along the difficulty direction reveals that pushing models toward "easier" representations reduces hallucination and improves accuracy. During GRPO training on Qwen2.5-Math-1.5B, the human-difficulty probe strengthens and positively correlates with test accuracy across training steps, while the LLM-difficulty probe degrades and negatively correlates with performance. These results suggest that human annotations provide a stable difficulty signal that RL amplifies, while automated difficulty estimates derived from model performance become misaligned precisely as models improve. We release probe code and evaluation scripts to facilitate replication.

Yesterday (30.10.25), Haneen answered this when I asked if Saji, the youngest in the family, is studying well:

"Yes, he studies and he excels.

Saji needs to buy tools to help him with his studies.

I bought this for $5.

Saji needs something like this every two weeks.

These are simple things."

Please help if you can:
