I got 3 consecutive emails warning that my budget crossed its $18 threshold. Opened it up: cost was 78 million. Thought it was a phishing attempt, logged into my actual account, and... still 78 million. EMOTIONAL DAMAGE.
Re:Code Golfing ARC-AGI with an Evolutionary Agent

Built an evolutionary code golf agent for Kaggle's NeurIPS 2025 Google Code Golf Championship. Solves ARC-AGI puzzles and compresses solutions to the fewest bytes through:
- Extensive prompt engineering
- An evolutionary database enabling cross-task crossover to escape local minima
- Hand-crafted templates to teach the LLM large refactoring tricks
Sharing what worked, what failed, and lessons for LLMs in program synthesis.
