Replit is no longer working with Anthropic, CEO says

Replit CEO Masad has confirmed to TechCrunch that the company is no longer working with Anthropic. According to his account, the decision was made for a number of different reasons, including cost.

TechCrunch points out that Replit announced a partnership with OpenAI in August, but until now there was never any indication that it was no longer working with Anthropic. In other words, the change of supplier did not arrive with a public announcement; it surfaced through a chief executive's comments in an interview.

For a company whose core product is built around AI coding, the choice of model provider feeds directly into cost structure and product roadmap. By listing cost among the reasons, Masad suggests that even AI coding tools with working business models still have to redo the arithmetic across multiple model vendors now that inference remains a meaningful expense.

Read as a timeline, the OpenAI partnership in August and the confirmed end of the Anthropic relationship in October sit about two months apart. That ordering implies a replacement rather than an abrupt cut, with a new supply relationship established before the older one wound down.

The episode matters because it turns multi-model strategy from a technical talking point into a procurement question. AI application companies no longer only ask which model performs better; they also ask which model costs less per unit of work and offers more flexible commercial terms.

For Anthropic, losing a public developer platform customer is a visible signal about its position in the developer ecosystem. For OpenAI, it is another expansion of its footprint among coding-focused customers. A single partnership change is not proof of a trend, though, and more comparable cases would be needed to confirm one.

What to watch next: whether Replit updates its model listings in public documentation or on its pricing page, whether it consolidates onto a single provider, and whether other AI coding tools that depend on frontier models make similar supplier adjustments.
