A deep technical breakdown of building a minimal LLM compiler from scratch in Python that lowers models (TinyLlama, Qwen2.5-7B) to optimized CUDA kernels across six IR levels. Demonstrates practical GPU optimization techniques (tiling, shared memory staging, bank conflict resolution, pipelining) with competitive performance (1.11-1.20× vs PyTorch/torch.compile on some ops) and includes reproducible CLI commands for each optimization stage.

Analysis of the economic trade-offs when using AI coding agents, arguing that productivity gains only make financial sense if paired with proportional reductions in code maintenance costs. The piece highlights a critical blindspot in AI-assisted development: increased code volume without corresponding maintenance efficiency improvements can actually increase total costs exponentially.

Simon Willison demonstrates practical patterns for executing LLM-generated code directly from shell scripts using shebang syntax, including examples with tool calls and YAML-defined functions.

Interactive visualization tool for Jensen-Shannon divergence, a symmetric divergence metric useful for comparing probability distributions. While mathematically foundational for ML work, this is primarily an educational visualization rather than a practical tool for daily AI development workflows.

Pre-registered robustness study of Meta's V-JEPA 2.1 across model sizes (80M-2B) reveals that representational drift (M2 metric) predicts failure on temporal corruptions but not image noise, non-monotonic scaling where larger models aren't reliably more robust, and unexpected orientation sensitivity despite temporal structure preservation.
