OpenAI co-founder and author of the term "wyb-coding" joins Anthropic

OpenAI co-founder and former director of AI at Tesla Andriy Karpatiy, also known as the originator of the term "wyb-coding," has joined Anthropic in what has become one of the most high-profile transitions in the AI industry in recent memory, Business Insider notes.

Carpathian announced his move on social network X on May 19, saying that the coming years in the development of large language models will be "especially important" and that he is excited to return to research and development. The developer will work on Anthropic's model pre-training team responsible for Claude's large-scale testing, wrote the head of that area, Nicholas Joseph, on Social Network X.

Karpatiy is one of the most well-known experts in AI. He was a researcher on OpenAI's founding team, later leading the Autopilot computer vision team at Tesla before returning to OpenAI again in 2023. After leaving the company for a second time in February 2024, he launched education startup Eureka Labs to create an AI assistant for teachers, Business Insider recalls.

Karpatiy also became the author of the term "wyb-coding". He first mentioned it in early 2025 in Social Network X, when he talked about a new approach to programming with the active use of neural networks. Later, he suggested using the term "agent-based engineering" to describe a new stage where AI agents create code under human control.

Carpathian's move comes amid an escalating battle for specialists between Anthropic and OpenAI. Anthropic has been actively strengthening its position in recent months thanks to the development of Claude Code and other tools for AI-based programming, writes Business Insider.
