How many people use Codex? 20 million — as of August 21

How many people use Codex? As of August 21, 2026, the answer is 20 million active users — up from 15 million barely a week earlier, and roughly 33x the ~600,000 weekly users OpenAI reported at the start of the year.[1][2][5] OpenAI's Codex and ChatGPT engineering lead, Tibo Sottiaux, announced the milestone on X, and most coverage reads the figure as Codex plus ChatGPT Work combined.[1][5][6] The numbers are company-reported, not audited, and OpenAI has never published its definition of “active.”[18]

The growth curve behind 20M (all figures as-reported):

The jump from 15M to 20M is the fastest gap between confirmed milestones so far — roughly five million new users in about a week.[2]

What did OpenAI announce on August 21?

Sottiaux's post did two things at once: celebrated the milestone and addressed the growing wave of complaints that Codex limits were draining faster than expected.[1][10]

“First of all, we have hit 20M active users for Codex some time this week. Second of all, this is cause for celebration and during the day we will credit every Codex and ChatGPT Work user with a BANKED reset that you can use at your own leisure.”[1]

He also said: “while we're not seeing anything abnormal, we do take it incredibly seriously and there is an ongoing investigation,” and teased that “we will have some other good news later too!”[1] That tease remains unconfirmed as of August 23 — there has been no follow-up post, so treat it as a promise, not a fact.[1][2]

What is a banked reset — and why did every user get one?

A banked reset is a saved usage-limit reset you can redeem whenever you choose, rather than a reset that fires automatically. Per OpenAI's Help Center: “Using a full banked reset resets both your 5-hour and weekly usage windows. As a result, your weekly reset date will move to roughly seven days after you redeem it.”[4] It shows up as “1 reset available” on the Codex usage page (chatgpt.com/codex/settings/usage), and CLI users can trigger it with /reset.[4][11][12]

Why give one to everyone? The stated reason is celebration of the 20M milestone.[1] The mechanic itself launched June 11, 2026 with one free reset for Plus and Pro users, plus referral-earned resets during promotions; Business accounts are eligible per-member, depending on the campaign.[12][9][11] Tibo has previously described users holding up to three banked resets at once, so the new credit is likely additive — but no expiration has been published for it.[2]

The rollout that missed its own deadline

Here's where the celebration soured. The reset was promised “during the day” on August 21, then Sottiaux posted a firmer deadline: “The banked reset will be there by 8pm PST. For all paid users of ChatGPT Work and Codex. Do with this information what you may.”[15][2]

8pm PST came and went, and many users reported the credit was “nowhere to be found.”[2] Some users did receive it — one reported draining 100% of their allowance in six hours after redeeming it — and OpenAI's community team acknowledged delivery was staggered.[3] Journalist Ed Zitron escalated the criticism (“Tibo promised a banked rate limit reset, then did not deliver one”), quoted here as reported by explainx.[2]

Are Codex limits actually shrinking?

The short answer: no confirmed cut — but OpenAI found real problems. The company's position moved in three steps: “not seeing anything abnormal” (August 21), then identifying sub2api — converting a ChatGPT subscription into API access — as one pattern among affected users, then on August 23 announcing it had found three usage inefficiencies (images in long sessions with multiple compactions, high p95+ usage for Computer History, and a conversation-title feature draining more than expected) plus a worse cache-hit rate for some users.[1][3] OpenAI says it is fixing these.[3]

For agencies, the practical read: usage allowances are not a fixed, published number per user — “OpenAI does not publish one fixed weekly allowance that applies to every user and workload.”[10] Budget for variance, and watch the usage page before assuming a client account is being throttled on purpose.

What's next: a new reset on August 24

OpenAI community manager VeitB announced the follow-up on August 23: “there's also a new reset incoming. This time the time when it happens is also part of the announcement. It will be 2026-08-24T21:00:00Z.”[3] Sottiaux clarified that as 2pm PST.[3] Whether the “other good news” tease lands alongside it is still unknown — we'll update this page when there's a verified follow-up.

Codex pricing in 2026

For quick reference, verified pricing as of August 19, 2026: Plus $20/month, Pro 5x $100/month, Pro 20x $200/month, Business per seat, and API billed on usage.[14] ChatGPT Work and Codex share the same usage meter — the 5-hour and weekly windows — even though Work is oriented to longer multi-step deliverables and Codex to repo-native development.[4] If you're deciding which to build client work on, capacity per dollar is the deciding number — that's the full pricing comparison.

Frequently asked questions

How many users does Codex have?

Codex crossed 20 million active users during the week of August 21, 2026, per OpenAI's Codex engineering lead Tibo Sottiaux — up from 15 million on August 13, 10 million on July 21, and 8 million on July 14.[1][2][5] The figures are company-reported, not audited, and most coverage treats them as combined Codex plus ChatGPT Work users.[6][18]

What is a banked reset in Codex?

A banked reset is a saved usage-limit reset you can redeem whenever you choose. Per OpenAI's Help Center, using a full banked reset resets both your 5-hour and weekly usage windows, and your weekly reset date moves to roughly seven days after you redeem it.[4] It appears as an available reset credit on the Codex usage page.

Did the Codex banked reset actually arrive?

Disputed. OpenAI promised the reset “during the day” on August 21, then set a firmer deadline of 8pm PST for all paid users — a deadline many users reported missing.[2][15] Some users did receive it.[3] OpenAI announced a new reset for 2026-08-24T21:00:00Z (2pm PST on August 24).[3]

Why are my Codex limits draining so fast?

OpenAI initially said it was “not seeing anything abnormal,” then identified sub2api usage as one pattern and, on August 23, reported finding three usage inefficiencies plus a worse cache-hit rate that it is fixing.[1][3] As of publication there is no confirmed evidence of a deliberate cut to Codex limits.[3][10]

Is 20M Codex-only or Codex plus ChatGPT Work combined?

Ambiguous. Sottiaux's announcement says “20M active users for Codex,” but the banked reset covers every Codex and ChatGPT Work user, and most coverage — Memeburn, KuCoin, Hello Entrepreneurs, StudioGlobal — treats the figure as combined.[1][5][6][7][22] OpenAI has not published a methodology.[18]

How much does Codex cost?

As of August 2026: Plus at $20/month, Pro 5x at $100/month, Pro 20x at $200/month, Business per seat, and API access billed on usage.[14] Per-model 5-hour window ranges vary by plan tier.
