Replit is no longer working with Anthropic, CEO says
Original reporting by TechCrunch
Replit refers to a popular AI coding platform that enables developers to build and deploy applications directly from their browsers. At TechCrunch Disrupt, CEO Amjad Masad announced that the company is no longer working with Anthropic, citing a combination of factors including cost, superior performance from OpenAI’s ChatGPT on internal benchmarks, and the overall strength of their partnership. This marks a significant pivot for Replit, which had previously relied on Anthropic’s Claude models to power its platform and was, until recently, a top-five customer of the AI safety company.
Clarifying the shift
While Masad’s onstage comments suggested a complete break, he later clarified that Replit customers can still access Anthropic models. However, OpenAI’s ChatGPT is now the default for powering Replit Agent, a move that is expected to significantly reduce Replit's spending with Anthropic, as most users adhere to default settings. The announcement prompted some confusion, with sources familiar with the partnership stating that the relationship was still active, and evidence showing Replit promoting Anthropic products just weeks prior. Masad ultimately stated that Replit remains "model agnostic" but considers OpenAI its "preferred partner."
Replit's strategic shift to designating OpenAI as its preferred partner for powering core features, while retaining user choice for Anthropic models, signals a significant reorientation in a rapidly evolving AI ecosystem. Amjad Masad’s stated reasons — a blend of performance, cost-effectiveness, and partnership strength — underscore the pragmatic calculus driving such decisions for platform providers. Yet, the conflicting accounts from insiders and the recent visibility of Anthropic models on Replit’s platform complicate the narrative, revealing the often-unseen complexities and fluid nature of these high-stakes technology alliances.
Broader Ecosystem Implications
This recalibration by a prominent AI coding platform carries broader implications for the competitive landscape of foundational models. It highlights the fierce contention among major players like OpenAI and Anthropic, where continuous innovation, measurable performance gains, and favorable economic terms are paramount for retaining and attracting large-scale customers. Replit’s move also emphasizes the power of defaults: while offering choice, the preferred model will likely capture the majority of usage, influencing market share and developer adoption. As enterprise integration of AI tools accelerates, platforms like Replit will increasingly prioritize robust, cost-efficient, and performant backend models to meet the demands of sophisticated business users, driving further competition and specialization within the AI model market. This saga serves as a potent reminder that even the most impactful partnerships are continuously subject to re-evaluation based on an ever-shifting technological and economic landscape.
Frequently asked questions

This decision was influenced by several factors, including improved performance of OpenAI's models in internal benchmarks, more favorable economic terms, and a stronger perceived partnership. While users can still access Anthropic models, OpenAI is now the preferred partner for their core agent.
- Can Replit users choose different AI models, or are they limited to the default?
- Replit maintains a model-agnostic approach, allowing users to select from various supported AI models, including Anthropic's Claude. Although OpenAI's ChatGPT is now the default for Replit Agent, users retain the flexibility to choose other models based on their preferences and specific development needs. This ensures developers have options for different applications and tasks.
