Interactive brain model: AI traces anatomy when you hear 'pass the salt'

mikeyk · x · 2026-09-02

Leveraging a cognitive science background, the author asked an AI to build an interactive model of the human brain tracing the anatomy involved in hearing a simple phrase like 'pass the salt'. The AI reasoned through the anatomy independently using no external assets. The author noted the model is more honest during operation, reporting when stuck rather than faking success. The model is priced at $10/$50, and cache read costs on the API have been cut by 75% to $0.25/MTok.
