This article explores how the two approaches in software development—plotting (top-down planning) and pantsing (bottom-up coding)—affect the use of AI tools. The author argues that AI delegates (autonomous) suit plotting, while AI assistants (collaborative) suit pantsing. In existing codebases, pantsing builds understanding and delegates hinder learning; in greenfield projects, delegates are less risky but may still rob programming of joy by removing the 'play to learn' process. The key is to match AI style to the current development phase.

Large language models often succeed on one formulation of a problem while failing on an equivalent formulation. Whether these failures arise from distinct internal circuits or different activation states of a shared circuit remains unknown. This study investigates whether arithmetic heuristic neurons are form-invariant across symbolic arithmetic, natural language word problems, and Python code in Llama-3 models. Using a two-stage pipeline of attribution patching and activation patching, we identify a compact set of neurons shared across all formats. Targeted interventions show this shared circuit is necessary and sufficient for late-layer arithmetic computation. Transferring activations from successful to failed executions recovers over 97% of errors for addition and subtraction, indicating cross-format failures arise from activation states rather than distinct circuits. Shared neurons consistently belong to the same heuristic families, demonstrating neuron-level form-invariance.

This study compares human and language model (LM) next-word prediction using EEG event-related potentials (ERPs), finding that only the 'surprisal' measure correlates with language-processing ERPs, especially for open-class words, and that scaling LMs does not guarantee more human-like cognitive processing.

A new study uses a simple car-wash question to reveal that language models often pre-commit to an answer before reasoning, failing to derive logically correct conclusions. Experiments on Qwen3-8B show systematic wrong commitments (recommending 'walk' when 'drive' is the only valid option). Activation-level analysis suggests hidden states already lean toward the wrong answer before output, even for rollouts that eventually answer correctly. The findings highlight a pre-reasoning decision bias in LLMs.
