OpenAI co-founder John Schulman joins rival LLM developer Anthropic

August 6, 2024: OpenAI Co-founder Schulman Joins Rival Anthropic - John Schulman, OpenAI co-founder, has left to join competitor Anthropic PBC, announcing his resignation on X. Schulman, who played a crucial role in developing ChatGPT and overseeing AI safety, cited a desire to focus on AI alignment. His departure leaves three OpenAI co-founders, with Greg Brockman also taking an extended leave. Anthropic, backed by over $7 billion in funding, claims its Claude 3.5 Sonnet model outperforms OpenAIs GPT-4o. This move follows the earlier exit of another key OpenAI researcher, Jan Leike, to Anthropic.
