Codex runs on every paid tier, with ceilings that rise by plan; exact multipliers are unpublished and have shifted more than once — the April 2026 "$100 sweet spot" tier came and the lineup shifted again around Astra. Chasing numbers is pointless; the mechanics are what stay stable.
The right upgrade decision observes which window binds first: throttled inside single sessions → the 5-hour layer is the constraint, and lighter models are the cheaper fix; capped every afternoon → the weekly layer is binding, and that's where an upgrade pays.
Factor in the reset rhythm too: global resets treat every tier equally, so during daily-refill sprees the marginal value of a higher tier is lowest, and during long silences it's highest. Watch the radar against your own throttle pattern for a week before spending.
FAQFAQ
What happened to the $100 tier?
It launched April 2026 alongside a global reset, and the plan structure has shifted since — the current lineup lives on the official pricing page. Archive pages (like the April 9 event) preserve the record.
How does Business quota work per person?
Business adds seats and administration; personal quota is in the same family as the top individual tiers. Buy it for the team features, not raw limits — verify current specifics on the official business page.
How do I know if I should upgrade?
Track a week with /status and the IDE status display: note what time of day you throttle and which window binds. Session-only throttling → no upgrade needed; daily weekly-layer caps → that's where the upgrade pays.
