Cartoon titled AI model loyalty, enterprise edition, subtitle: share of engineers' AI coding work at one HR software company, May vs October. On the left, next to an office door marked EXIT with a yellow sticky note reading It's not you. It's your price per token. - Finance, a crying purple robot labeled Anthropic models (leaving with its stuff) carries a moving box marked 57% to 18%. In the middle a sad developer at a desk with a monitor says: But I liked how it wrote code... Beside him, a smiling accountant in glasses holds an invoice and says: I liked how it wrote invoices. On the right, a smiling teal robot labeled OpenAI models (moving in) rushes in carrying a box marked 16% to 52%. Small note: cartoon; shares are Rippling's, as reported. Footer: The Information (Oct 24, 2026): at Rippling, Anthropic models did 57% of engineers' coding work in May, OpenAI's 16%. Now OpenAI's share is 52% and Anthropic's 18%. Rippling wanted to cut costs, and OpenAI was cheaper, its CEO said. Illustration; characters are not real people. No logos; no endorsement. Watermark: MODEL, readmodelmag.com.

Developers argue all year about which AI model writes the best code. At one big software company, the deciding vote turned out to belong to finance.

What was reported. In a story published October 24, 2026, titled "Anthropic's Margin is OpenAI's Opportunity," The Information's Laura Bratton and Stephanie Palazzolo report that OpenAI has been winning AI coding work away from Anthropic with discounts and free credits, while Anthropic has played hardball in negotiations. The example that took off on X on Saturday:

  • At Rippling, the HR software company, Anthropic models handled 57% of the coding work of its engineers in May, and OpenAI models 16%.
  • Five months later, that has flipped: OpenAI 52%, Anthropic 18%.
  • CEO Parker Conrad told the outlet Rippling wanted to cut costs, and OpenAI proved cheaper.

Coverage of the same article says OpenAI also gave Replit more than 30% off a contract worth over $100 million a year, after Anthropic declined to extend Replit's earlier discount without a bigger spending commitment. Replit's CEO had already said onstage on October 16 that OpenAI is now the default for Replit Agent, citing cost, partnership and performance; Claude models remain available to customers who pick them, TechCrunch reported.

The other side. None of this says one model is better. Rippling still uses Anthropic for almost a fifth of the work, and when routing between providers is this easy, the next price cut or the next better model can move the work right back.

Our take. For years, picking a coding model felt like picking a favorite editor. At company scale it is turning into a procurement line: if two models are close enough on your tasks, the per-token price decides. If you build on these models, keep your prompts, evals and tooling portable so you can switch, in either direction, without a rewrite.

What we did and didn't do: we read The Information's headline and the reporters' public post, TechCrunch's Replit report, and other outlets' summaries of the article on October 24, 2026. The full Information article is paywalled and we did not read it in full; the Rippling and Replit figures are as reported there and have not been published by either company. We have not tested either company's models for this story. Not sponsored; no affiliate links.
