OpenAI is adding a new seat tier called Premium to its ChatGPT Business plan. Compared with the existing Standard seat, a Premium seat comes with 5x more usage and drops the five-hour usage limit. Pricing is 125 USD (about 20,000 yen) per user per month, and the two seat types can be mixed inside the same workspace. A waitlist is already open ahead of general availability[1].
What the Premium Seat Actually Includes
ChatGPT Business is a self-serve plan built around a shared workspace for a team. The Premium seat announced this time comes down to 3 things: 5x the usage of a Standard seat, removal of the five-hour usage limit, and predictable weekly usage resets[1].
According to OpenAI, the most common request from ChatGPT Business customers has been an expanded seat option with more capacity and usage built in. As teams push ChatGPT into bigger tasks such as organizing inventory, building marketing campaigns, analyzing business performance, and improving customer experiences, they hit limits and lose momentum more often[1].
There is also an escape hatch for teams that run out. A workspace that reaches its limit can add shared workspace credits, managed centrally by the workspace owner[1].
125 USD per Month, 100 USD Billed Annually, Seat Types Can Be Mixed
A Premium seat costs 125 USD (about 20,000 yen) per user per month, or 100 USD (about 16,000 yen) per user per month when billed annually. Standard seats stay where they are, at 25 USD (about 4,000 yen) per user per month, or 20 USD (about 3,200 yen) billed annually[1].
※1 USD = 159 JPY
The part worth noting is that both seat types can coexist in one workspace. Admins can reassign seat types as workloads shift, monitor usage across the workspace, and handle billing and spend limits in a single place[1]. Heavy users no longer need a separate subscription, so work does not get scattered across parallel accounts.
As background, ChatGPT Business requires a minimum of 2 standard ChatGPT seats. Standard seats include access to Codex as well as ChatGPT, but dedicated Codex seats can no longer be added to new Business workspaces as of June 24, 2026[2].
Up to 500 USD in Credits for the First 10,000 Customers, Ending August 20
Ahead of general availability, OpenAI is running a limited-time promotion tied to the waitlist. The first 10,000 eligible ChatGPT Business customers receive 100 USD worth of workspace credits (2,500 credits) for each Premium seat they add, up to 5 seats, for a maximum of 500 USD (about 80,000 yen)[1].
Signing up requires the email address tied to the Business workspace owner account, and some registrants may be selected for early access before general availability. The promotion ends on August 20, 2026[1][2]. If you are not the workspace owner, the fastest path is to pass the offer to whoever manages the account internally.
Raising the Ceiling on Business Pricing
The announcement has been reported as part of OpenAI's push to broaden revenue beyond consumer products while it prepares for an initial public offering[3]. The company keeps expanding into business and enterprise markets, with competition from Anthropic, which has won large corporate customers through coding tools, cited as the backdrop[3].
The 5x price gap between 25 USD and 125 USD maps directly onto the 5x usage difference. Alongside usage-based API billing, seat-based subscriptions are now being split into tiers as well, and the tiering of AI pricing has become clearly visible on the business side. Whether Japanese companies see exactly these figures depends on country and currency, so the safest move is to check the amount shown inside your own workspace[2].
Summary
The ChatGPT Business Premium seat is a straightforward trade: 125 USD per month buys 5x usage and no five-hour limit. Because it mixes with Standard seats, a company can raise the ceiling only for the handful of people who keep hitting limits, instead of paying more for everyone. The credit promotion closes on August 20, so existing customers should review their usage sooner rather than later.
