(Unpacking) AI's Impact on System Architecture
summary
A thousand synthetic expert personas produce full architecture blueprints for a VC website, using LLMs (GPT-series and reasoning O-models), image generation (DALL·E 3 and image-search), Azure-hosted runs consuming ~43M tokens and costing under $1,000 for the experiment. Outputs include React frontends, Java/Python services, Docker/Kubernetes, AWS S3 and analytics; designs get ranked by a tournament of peer reviews, yielding a single consistent winner but revealing US‑spelling bias and security‑skew, so retries and human review remain necessary.
