Ditching Claude and Codex subscriptions for API billing raised an engineering team's AI costs 30x

Geoffrey Huntley shares an experiment by Arunabh Dastidar: an engineering team cancelled individual Claude and Codex Max/Pro subscriptions and routed all engineering work through the API, with no change to headcount or backlog.
The result: five engineers previously paid $800–1000/month combined; the same work via API cost roughly $1000/day — a 30x jump overnight. The author frames subscription tiers as labs selling intelligence at deep discounts, alongside data on flagship release cadence shrinking from 38 days (2023) to 8 days (2026), Anthropic spending $1B+ a year on RL environments, and Surge/Mercor reportedly earning $1B/$2B a year selling them.
