Blogger theo ran the math on OpenAI's updated Codex plan changes: the $500/month plan works out to roughly $10,500 of API-equivalent usage per month, while the $200 plan nets about $4,300 (the reposter cites $3,500).

Either way, OpenAI is still heavily subsidizing power users — subscribing beats paying API rates by an order of magnitude. The huge gap between subscription pricing and API pricing suggests OpenAI is aggressively courting developers, though the sustainability is questionable.
