"Opus 5.5 Was a Nuclear Bomb": Writer Says Anthropic Upended OpenAI, $100 Codex Nearly Unusable
StewartalsopIII · x · 2026-10-01
Investor Stewart Alsop III argues Opus 5.5 landed like "a nuclear bomb of egalitarian dimensions" on OpenAI precisely as it was about to copy Anthropic's "too expensive, too dangerous, you can't have it" posture.
He also reports a real-world data point: on a $100/month plan across both OpenAI and Anthropic, Codex credits have become barely enough to use. The post ties competitive dynamics to tangible quota pain for high-tier subscribers.
