OpenAI Reprices Codex
OpenAI moved business customers of Codex to a token‑based pricing model, a shift from per‑message billing that makes costs easier to forecast for enterprise contracts and procurement. The company is also reporting enterprise revenue growth—about 40% of revenue now—and is preparing for a possible public listing while projecting ad revenue ramps that some reports peg at $2.5 billion this year and far higher longer term.

OpenAI quietly changed how it charges companies for Codex on April 2: instead of billing many business users per message, it now bills by tokens, which are the chunks of text the model reads and writes. That is closer to paying for cloud storage by gigabyte than paying for every email you send. (help.openai.com) The switch applies to new and existing ChatGPT Business customers and to new ChatGPT Enterprise customers, while older Enterprise and education workspaces stay on the legacy message system until OpenAI migrates them. OpenAI also tied the change to new “Codex-only” seats inside Business and Enterprise plans. (help.openai.com 1) (help.openai.com 2) For a finance team, per-message pricing is awkward because one “message” can be a tiny bug fix or a giant code review. Token pricing turns that into a meter with a unit procurement teams already know from application programming interface contracts. (help.openai.com) (developers.openai.com) OpenAI paired the pricing change with a sales push. A Help Center note says eligible ChatGPT Business workspaces can earn $100 in credits for each new Codex seat that gets activated, up to $500 total, starting April 2. (help.openai.com) That tells you who this change is really for: companies buying software in bulk, not individual coders buying a monthly plan. OpenAI’s own release notes say ChatGPT seat prices for Business were cut by $5 per month at the same time Codex moved to token-based usage. (help.openai.com) The backdrop is that enterprise sales are no longer a side business for OpenAI. Chief Financial Officer Sarah Friar told CNBC that enterprise now makes up about 40% of OpenAI’s revenue, which means billing mechanics suddenly matter a lot more than they did when the company was mostly selling subscriptions to individuals. (cnbc.com) Friar told CNBC on April 8 that OpenAI plans to reserve a slice of shares for retail investors when it goes public. Reuters, citing prior reporting, said the company could file for an initial public offering as soon as the second half of 2026. (cnbc.com) (reuters.com) Public-market investors usually like revenue that is easier to model quarter by quarter. A token meter for coding work is easier to forecast than a message bucket, especially when the same company is also telling investors that advertising could bring in $2.5 billion in 2026 and $100 billion by 2030, according to Axios. (axios.com) So the Codex repricing is not just a billing tweak. It is OpenAI making its coding product look more like enterprise infrastructure, at the same moment it is selling Wall Street on a future built from enterprise contracts, consumer subscriptions, and a very large advertising business.
