OpenAI: the pricing arc
OpenAI's tracked moves stay close to the rate card. A reasoning model was cut steeply on the day a premium variant launched above it, setting the pattern of a falling floor with a new rung over it. The flagship family then shipped as three named rungs in one announcement, and the rungs moved separately soon after, the smallest one far more than the top. Promotional pricing arrived with a published end date, so the reversion is an increase that needs no announcement. The one step away from tokens is on the enterprise plans, where the pricing page discloses credit-based billing beside token-based billing. Everywhere else on this ledger the unit is still the token.

The move
OpenAI's 'Sign in with ChatGPT' lets Plus and Pro subscribers use their ChatGPT plan for AI requests in participating third-party apps and sites, with eligible requests counting toward the ChatGPT Work and Codex usage included in their plan, without needing to create or share an OpenAI API key.
The SPP read
Participating apps and sites can now run eligible AI requests against a subscriber's ChatGPT Plus or Pro plan. Those requests draw down the Work and Codex usage already included in the subscription, at rates the vendor says may differ between an app and ChatGPT, under a weekly cap per app set as a share of the plan's usage. The plan fee, rather than a separate API meter, covers inference done inside another vendor's product, and the partner's own subscription and charges stay separate.
The move
When users reach their ChatGPT plan limits, third-party apps connected via Sign in with ChatGPT can draw on available ChatGPT credits, but only if the user has explicitly opted in. This setting is off by default.
The SPP read
Once a subscriber exhausts the plan's included usage, apps connected through Sign in with ChatGPT can draw on that subscriber's available ChatGPT credits. The setting ships off, applies across participating apps at once, and works only for an app whose weekly limit is set to the full plan allowance. That makes a personal credit balance an overflow meter for third-party products, with the brake held by the user.
The move
OpenAI launched OpenAI Marketplace, a program that lets eligible enterprise customers apply part of their OpenAI spending commitment toward qualifying partner products built on OpenAI models, rolling out alongside DevDay announcements.
The SPP read
The move is in the terms around OpenAI's enterprise spending commitment, not in any published rate: part of a commitment can now be applied to qualifying third-party products built on OpenAI models. This follows the cloud-marketplace drawdown pattern and widens what prepaid OpenAI spend can buy, with no rate movement stated. Only eligible enterprise customers and qualifying partner products are in scope.
The move
OpenAI's API documentation says developers enable the Ultrafast tier per request by setting service_tier to 'ultrafast', making speed a selectable priced tier rather than a separate model.
The SPP read
OpenAI added a faster service tier for GPT-6 Astra in the Responses API. Developers select it on each request through the service_tier parameter instead of calling a different model. The unit stays tokens; what moved is the packaging, with latency now sold as its own priced option on the same model.
The move
OpenAI launched ChatGPT Pro 500, a new $500/month plan that includes Astra Ultrafast and the highest included usage of its Pro plans.
The SPP read
OpenAI added a plan above its existing Pro subscription, with the highest included usage in the Pro lineup and the only access to the Ultrafast mode in ChatGPT Work and Codex. The unit is still a flat subscription with an included allowance; what moved is the top of the ladder, where speed and allowance now sell as an edition of their own instead of as extra credits bought on a lower plan.
The move
OpenAI reopened new ChatGPT Pro 200 subscriptions at an unchanged $200/month price but with a lower usage allowance than previously offered, which it attributed to its increasingly efficient models.
The SPP read
New ChatGPT Pro buyers receive less included usage on the flat monthly subscription, while the list price stays the same, so the effective cost per unit of work rises with no rate moving. Subscribers eligible for grandfathering keep the earlier allowance. OpenAI describes the reduction as a consequence of model efficiency.
The move
OpenAI says GPT-6.1 Sol nearly matches GPT-6 Astra's intelligence on agentic coding, computer use, and professional work at one-fifth of Astra's standard input and output token prices.
The SPP read
OpenAI released GPT-6.1 Sol, a point update to its lower-priced Sol tier, and pitched it as close to GPT-6 Astra on agentic coding, computer use and professional work. The one-fifth figure compares two tiers' standard token rates; no existing rate moved. The Sol tier kept its prior token pricing while the capability on it moved up, which makes this a hold on per-token rates.

The move
OpenAI's top Codex Pro tier at $500/month gates access to its 'Astra Ultrafast' speed mode.
The SPP read
OpenAI added a new highest Pro plan and placed its fastest speed mode inside it, making speed a capability that separates editions. Lower Pro tiers cannot reach the mode by buying more credits. Faster output is now sold through the plan a buyer holds.

OpenAI added a new highest Pro plan and placed its fastest speed mode inside it, making speed a capability that separates editions. Lower Pro tiers cannot reach the mode by buying more credits. Faster output is now sold through which plan a buyer holds, not through more consumption.
The move
OpenAI bills GPT-Live 1 voice sessions at $0.05 per minute, metered per second without rounding up to a whole minute, with backend model and tool usage charged separately.
The SPP read
With GPT-Live 1 reaching general availability in the API, OpenAI has put a published rate on voice sessions charged by elapsed time and metered per second, with no rounding up to whole minutes. That session meter covers only the voice layer; backend model and tool usage is charged separately, so a session's total cost stacks a time-based meter on top of OpenAI's other usage charges. No prior rate is cited for this unit, so this reads as a new rate card.

The move
OpenAI restructured the ChatGPT Business plan by introducing two distinct seat tiers—a Standard seat at $20/month and a Premium seat at $100/month (with monthly billing at $25 and $125 respectively)—replacing the previous single $20/user/month pricing, while also updating included features and removing the 2+ user minimum in favor of a 2–200 employee range.
The SPP read
On August 30, 2026, OpenAI's ChatGPT Business plan offered two kinds of seat where it had offered one: Standard seats at the existing per-seat rate and Premium seats at a higher one, with the plan's user range widened from a minimum to a stated band of company sizes. The seat stayed the unit; what changed is that one workspace now buys two kinds of it, priced apart, and the Premium rate arrived alongside a launch credit that has since ended.

On August 30, 2026, OpenAI's ChatGPT Business plan carried two seat tiers where it had carried one: Standard seats at the existing per-seat rate and Premium seats at a higher one, with the plan's user range widened to two hundred seats.
The move
OpenAI cut the prices of its frontier GPT-5.6 Sol model for developers by more than 20% for the next three months, effective August 21, 2026.
The SPP read
What moved is the developer API rate on OpenAI's current frontier model; the token meter and how usage is counted stay the same. The cut is time-boxed, so it works as a promotional discount against the standing rate card. It keeps OpenAI's frontier tier on the tokens end of the arc and puts pressure on competing frontier rates while the window is open.

The move
On August 13, 2026, OpenAI opened a limited preview of Ultrafast, a new service tier that runs GPT-5.6 Sol up to 14 times faster than Standard processing, to a select group of API customers, with access to expand as capacity grows and no rate published.
The SPP read
On August 13, 2026, OpenAI opened a limited preview of Ultrafast, a separate service lane that runs GPT-5.6 Sol at a multiple of Standard processing speed, to a select group of API customers, with no rate published. The lane is defined by speed on the same model, so the pricebook now holds a slot with a service level and no price. The rate, when it prints, will show what a faster lane on an unchanged model is priced at.

The move
On August 10, 2026, OpenAI announced Premium seats for ChatGPT Business at $125 per month or $100 per month billed annually, alongside the standard seats at $25 monthly or $20 annually, with $100 in workspace credits per qualifying Premium seat for the first 10,000 waitlist workspaces, up to five seats; the credit offer closed by late August.
The SPP read
On August 10, 2026, OpenAI announced Premium seats for ChatGPT Business at a higher per-seat rate than the standard seats, monthly or annual, and attached a workspace credit per Premium seat for an early cohort of waitlist workspaces, capped at a handful of seats each. The credit closed by late August; the seat class stayed. Read with the Business restructure that followed on August 30, the arc shows a seat unit splitting into two priced kinds inside one plan, the standard seat price unchanged.

The move
OpenAI added a footnote to Enterprise pricing clarifying that both credit-based and token-based pricing are available for Enterprise plans, and relabeled the 'Messages and interactions' feature row to 'Everyday text chats' while removing GPT-5.5 Instant as a listed model from Business and Enterprise plans.
The SPP read
OpenAI updated its Enterprise pricing page to formally disclose that both token-based and credit-based billing are available on Enterprise plans, marking a structural clarification of which units buyers may be metered on at that tier. Separately, a listed model was removed from the Business and Enterprise plan feature matrix, narrowing the visible access set for those tiers. A feature row was also relabeled, repositioning how the capability is surfaced to buyers without a stated change to underlying limits.
The move
OpenAI now gives ChatGPT free and Go users unlimited everyday text chats with GPT-5.6 Luna, plus a new think button for harder questions, which removes rate limits as an upgrade lever for the free tier.
The SPP read
The included chat allowance on ChatGPT's free and Go tiers changed from capped to unlimited for everyday text chats on GPT-5.6 Luna. A think button for harder questions also comes to these tiers, so some reasoning capability moves down the plan ladder. Message volume on the bottom tiers no longer separates them from paid plans, which leaves model access and reasoning depth as the remaining differences.
The move
On July 30, 2026, OpenAI cut GPT-5.6 Luna prices by 80%, to $0.20 per million input tokens and $1.20 per million output tokens, cut GPT-5.6 Terra prices by 20%, to $2 per million input tokens and $12 per million output tokens, and added a Fast mode for GPT-5.6 Sol, per OpenAI's official announcement.
The SPP read
One announcement, three prices. On July 30, 2026 OpenAI cut GPT-5.6 Luna steeply, trimmed GPT-5.6 Terra by a smaller step, and added a Fast mode for Sol. The headline write-ups reported Luna's cut; the card listed all three. The cheap rung got radically cheaper while the flagship edged down, which is what a price-performance frontier looks like when a vendor moves the whole curve at once.

One announcement, three prices.
The move
GPT-5.6 (Sol, Terra, Luna) launched on July 9, 2026 and became OpenAI's new flagship family, with Sol matching GPT-5.5's $5/$30 pricing; GPT-5.5 remains available but is no longer the current flagship.
The SPP read
GPT-5.6 launched July 9 with Sol as the flagship at the same list price as the GPT-5.5 it superseded. The August 22 move makes this an arc event: Sol's price went on a clock, with the developer pricing page listing a lower promotional rate that holds at least through November 21, 2026. A discount with a published end date is a promotion, and its withdrawal is an increase nobody has to announce. Google shipped the same instrument in the same window, with Gemini prices that revert on January 1, 2027.
Read revised Sep 15, 2026Reason: Read revised to describe the change without repeating the price points, which stay in the move record.
GPT-5.6 launched July 9 with Sol as the new flagship at $5 per million input and $30 output on short context, the same list price as the GPT-5.5 it superseded; OpenAI positioned Terra, at half that, as the 5.5 analog.
The move
OpenAI stated that GPT-5.6 Luna is priced at $1 per 1M input tokens and $6 per 1M output tokens.
The SPP read
One announcement, three named rungs: a small tier at a fraction of the mid, a mid at half the top, and the top holding the flagship rate. Model families used to ship as one price with a mini beside it; this ships as a designed ladder, and the design is the point. Named rungs give the meter a packaging layer: buyers self-sort by workload instead of negotiating, and the vendor gains rungs it can move independently later. The ledger shows that option getting exercised within weeks, when the bottom rung was cut by four fifths and the middle trimmed while the top held. A ladder is the set of places a future price change can land without touching the others, and this vendor built one on purpose.
The move
OpenAI charges $5 per million input tokens and $30 per million output tokens for API use of GPT-5.5.
The SPP read
A six-to-one output premium puts the price on generation, not context. For application vendors pricing on top of the API, the asymmetry matters more than the headline rate, because features that read long and write short have a different unit cost than features that write long. Blended per-request pricing built on an average mix breaks the day the mix shifts. Price the direction your workload actually spends.
The move
OpenAI cut the price of o3 by 80%, with new pricing of $2 per 1M input tokens and $8 per 1M output tokens, effective June 10, 2025.
The SPP read
A deep cut on the reasoning model, announced the same day a pro variant arrived at a multiple of the new rate, is one decision expressed as two prices. The cut moves the base model toward commodity territory and the simultaneous premium launch keeps a rung above it for the spend to reach. The price of last year's frontier falls, and a new rung appears above it, so the falling floor never brings the ceiling down with it. Read the gap between the rungs rather than either price alone.

An 80% cut on the reasoning model, announced the same day a pro variant arrived at ten times the new rate, is one decision expressed as two prices.
