CodeRabbit spends tens of millions of dollars a year on AI. Six months ago, Anthropic was its main supplier. Today it is OpenAI, and the reason is not model quality — it is what happens when the tokens run out.
Last week this column covered the broader enterprise AI pricing and spend chaos; this week the delta is specific. Anthropic has drawn a hard line at the token cap, and Sonnet 5.5 is the product it hopes will make that line survivable.
Here’s the mechanic. Enterprise buyers who commit to spending millions annually get roughly 15% off list price from Anthropic, according to managers at three software firms that buy from both vendors. When those customers burn through their contracted token volume, the discount dies. They renegotiate or pay standard rates. There is no cushion.

OpenAI handles the same cliff with a grace period. A licensing adviser familiar with both companies told The Information that OpenAI gives customers the remainder of the current month plus one additional month to agree a new contract before list prices apply — up to two months of breathing room.
Cloud vendors go further still. Amazon, Microsoft and Google typically let customers keep their discount on usage above their commitment for the rest of the contract term, Jeff Muscarella of NPIFinancial told The Information. The hyperscalers treat an overage as a billing event. Anthropic treats it as a repricing event.
That distinction is what sent CodeRabbit to OpenAI, according to chief executive Harjot Gill. And it is what makes Anthropic’s position look, at first pass, like a gift to its most aggressive competitor. OpenAI hired its first worldwide sales chief this month, and Frederick Philipson of Redress Compliance told The Information that OpenAI is now the more aggressive of the two on discounts as it pushes into enterprise sales.
The stakes are not small. More than 100 companies spent over $10 million a year with Anthropic in the 12 months to June, and more than 1,000 spent over $1 million. Meta and Cursor are among the major customers. Anthropic’s revenue passed OpenAI’s for the first time last quarter. Both companies have cut list prices in recent weeks — Anthropic with a cheaper Opus model, OpenAI by halving GPT-6 prices.
Now the turn. Anthropic’s hard line is not a blunder. It is coherent and legible.
The company has been positioning for a potential public offering, and consumption-based revenue models tend to be more legible to public market investors than bundled deals. By splitting enterprise pricing into a $20 per user per month platform access fee plus metered API-rate charges for every token consumed, Anthropic can present cleaner unit economics. Bundled models obscure whether revenue growth is coming from genuine adoption or just seat expansion.
