# Replit CEO Amjad Masad says Replit no longer works with Anthropic, citing cost, partnership and performance; a source says the partnership is still in place

Onstage at TechCrunch Disrupt on Oct 16, 2026, Replit CEO Amjad Masad said Replit is "no longer working with Anthropic", calling it "a decision based on both cost, partnership, and performance" and saying OpenAI's Sol and Astra build vibe-coded apps better. TechCrunch notes conflicting signals: a person familiar said the partnership was still in place, and a late-September Replit post listed Claude Fable 5 and 5.1 in Replit Agent's production setup.

## Key facts
- Said onstage at TechCrunch Disrupt 2026 (Oct 16); reported by TechCrunch's Lucas Ropek
- Masad: 'It was a decision based on both cost, partnership, and performance'; 'Sol and Astra perform better on building vibe-coded applications from scratch' on an internal and a public benchmark; 'I think ChatGPT is better now'; 'we just felt like they were a better partner for now'
- Replit announced a partnership with OpenAI in August 2026
- Conflicting evidence (TechCrunch): an unnamed person familiar with the partnership said it was still in place; a late-September Replit blog post cited Claude Fable 5 and Fable 5.1 running in Replit Agent's production environment; a Replit product employee posted about using Opus 5.5 around the same time
- Which models Replit now runs in production was not confirmed; no Anthropic response in the article; Replit had not replied to TechCrunch at publication
- Other figures from Masad: enterprise grew from ~2% of revenue last year to ~15% this year; more than 50% of revenue is B2B; ARR not disclosed

## What happened

At TechCrunch Disrupt, Replit co-founder and CEO Amjad Masad said the company had stopped working with Anthropic. He gave
cost, the partnership and model performance as the reasons and said OpenAI's models now do better on Replit's benchmarks for
building apps from scratch. Replit, one of the best-known Claude-powered coding platforms, signed a partnership with OpenAI
in August.

TechCrunch could not reconcile the claim with other evidence. A person familiar with the deal said the Anthropic partnership
was still in place, and Replit had named Claude Fable models in its production stack only weeks earlier.

## Why it matters

Coding platforms are among Anthropic's biggest API customers. A public break by a major vibe-coding company, announced in the
same week Anthropic told investors its growth was slowing, is a competitive signal for OpenAI. Until Replit or Anthropic
clarifies, the claim is a CEO's statement contradicted by an anonymous source.
