OpenAI is adding a new, higher-end ChatGPT Pro subscription tier aimed squarely at developers and power users who are pushing its new Codex coding assistant to the limit.

In a post on X, OpenAI announced a new $100/month Pro tier inside ChatGPT, positioned between the existing $20/month Plus plan and the full-fat $200/month Pro offering that’s been around for hardcore users and teams. The headline change: the new Pro tier gives you 5x more Codex usage than Plus, making it better suited for long, high-effort coding sessions instead of quick debugging runs.

Crucially, this isn’t a “Codex-only” SKU – it’s a full ChatGPT subscription. Pro ($100) still includes all the usual Pro features in ChatGPT, including access to the exclusive Pro model, plus unlimited use of the Instant and Thinking models for regular chat, writing, analysis and research. In other words, you’re paying extra primarily to remove the friction of running into Codex limits mid-build, not to unlock some completely different app.

To sweeten the deal at launch, OpenAI is temporarily boosting Codex limits even further: until May 31, new $100 Pro subscribers get up to 10x the Codex usage of ChatGPT Plus, giving solo devs and small teams a chance to stress-test Codex on bigger projects – think full repo refactors, multi-file agents or long-running coding sessions – without hitting the brakes too early.

There’s a trade-off for existing users, though. As part of this reshuffle, OpenAI is dialing back the one-off Codex promo on the $20 Plus plan and “rebalancing” Codex usage there, shifting it from super-long marathons in a single day to more steady availability spread across the week. The company is pretty clear about positioning now: Plus at $20 remains the best value for day-to-day ChatGPT and light-to-moderate Codex use, while the new $100 Pro is pitched as the “accessible upgrade path” if you’re constantly maxing out those coding sessions.

Zooming out, this move fits into OpenAI’s broader ChatGPT pricing ladder, which in 2026 spans Free, Go, Plus, Pro, Business and Enterprise, with Go at $8, Plus at $20, the existing $200 Pro for extreme workloads, and then Business/Enterprise for teams with admin controls and stricter data privacy. Codex is bundled into all the paid tiers, but the practical difference has always been how much real usage you can squeeze out before hitting limits – and that’s exactly what this new Pro tier tries to solve for heavy coders.

For everyday users, nothing really changes: ChatGPT Plus is still the sweet spot if you mainly write, summarize, research, or occasionally tap Codex to fix a function or script. But if ChatGPT has quietly become your primary coding environment – and you’ve been bouncing off Plus limits regularly – the new $100 Pro tier is OpenAI’s way of saying: here’s more runway, without having to jump straight to $200/month.
