Dev compares $100 tiers: Opus 5.5 outlasts and outperforms OpenAI's fast-burning Ultra quota
cyannick · x · 2026-10-19
A developer who upgraded his Codex subscription to the $100 tier shares a hands-on comparison:
- He now mainly uses Opus 5.5; against Astra high, Opus high offers more usage, runs faster, and needs fewer iterations.
- In his view, Opus is currently the best value at $100 — the opposite of a few months ago.
- OpenAI's $100 plan burns quota much faster: one Ultra planning run plus high mode all morning consumed 50% of his weekly allowance.
