OpenAI Group PBC ↗

Company

OpenAI’s commercial model and product organization. Official partner announcements following the 2025 recapitalization and OpenAI’s 2026 board summaries use the name OpenAI Group PBC; OpenAI Foundation is a separate nonprofit. This profile distinguishes historical structures, the current commercial entity and individual funding announcements. The brand’s origin date is not treated as the current entity’s incorporation date.

Founded: Not provided; 2015-12-11 is OpenAI’s public introduction date. The current Group PBC’s legal founding date is not documented; earlier origins appear in the history.
Headquarters / public address: Not provided; The current headquarters is not documented. Historical operating locations and announcement locations are recorded separately.
Entity & listing status: Listing status not documented; The official RSS entry dated 2026-06-08 confirms a confidential draft S-1 submission, without a timetable for further action. A completed listing, ticker and market capitalization are not documented.OpenAI confidential draft S-1 submission · Official RSS summary ↗

Research & products

Developer statementThe March 2026 funding summary emphasizes frontier AI, next-generation compute, ChatGPT, Codex and enterprise demand. It describes research and product priorities, without establishing the performance of individual versions.OpenAI March 2026 funding · Official RSS summary ↗

Financial & funding snapshots

Funding and pre-money valuations retain their announcement-date snapshots. February and March disclosures are not combined; Microsoft’s reported approximately $135B stake value in 2025 is not OpenAI’s total valuation. The summaries use only $, with no ISO currency. No reliable current market capitalization is available. Full articles, closing conditions, complete financials and nonprofit control arrangements still need verification.

Billing & payment details

OpenAI API

Listed currency: USD
Billing model: Prepaid / account credit / Usage-based

The API uses metered billing and may draw on prepaid credits. Spending alerts notify without stopping requests. Organization and project hard spending caps act independently and return 429 for affected requests. Enforcement takes time to propagate, so actual spending can slightly exceed a cap. Raising or removing a cap restores access as the update propagates; otherwise, wait for the next monthly reset. An exhausted prepaid balance requires a top-up. Monthly spending caps are not flat subscriptions. As of 2026-10-29.

Billing, currencies and benefits apply to the products and dates shown.API usage and subscription benefits are separate. Listed and settlement currencies may differ; actual payment depends on your account conditions.

Developer model prices

Prices are per million text tokens, matched by currency, processing mode and input tier. Caching, tools, media and taxes may cost extra. These are not per-request or subscription totals. A listed price does not guarantee that a model is still available.
