Replit switches its default coding model to OpenAI
Replit's default moved to OpenAI on October 17 while Anthropic remains selectable; model defaults can shift usage without a code change.
- reported enterprise revenue this year
- 15%
- reported enterprise revenue last year
- 2%
- reported B2B revenue share
- 50%+
TechCrunch reported on October 17 that Replit made OpenAI's ChatGPT the default model after CEO Amjad Masad discussed the company's relationship with Anthropic. The article says customers can still access Anthropic models, so the change is a default choice rather than a complete removal. Replit says its enterprise business is now more than half of revenue and expects about 15% of revenue from enterprise customers this year, compared with 2% last year.
The story matters because a default can move most traffic without a user changing code. It also shows why a provider statement should be read with the follow-up: the article reports a public claim that Anthropic work had ended, then a clarification that customer access remains. Builders who depend on model behavior should record the selected provider and model, not assume the product name is stable.
What you can do with it
Pin the exact model and provider in one coding workflow. Run a fixed acceptance set after every platform update, record the default shown to a new user, and keep one fallback route. Compare accepted output, repair time, and cost before you allow an automatic model change.
Our take
Default models are a distribution decision as much as a technical one. Replit's change may reduce provider spend because many users stay with the default, but the report does not prove a quality win. Pinning the model protects repeatability while a short comparison shows if a switch is worth it.
