"In January, Tworek, who led its efforts on the "reasoning" of AI models, left OpenAI after seven years, saying he wanted to explore "types of research that are hard to do at OpenAI." He wanted to work on continuous learning-the ability of a model to learn from new data over time while retaining previously learned information. People close to Tworek said his appeals for more resources such as computing power and staff were rejected by leadership, culminating in a stand-off with chief scientist Jakub Pachocki."
"Last month, Vallone, who led model policy research at OpenAI, joined rival Anthropic. Two people familiar with her exit said she was given an "impossible" mission of protecting the mental health of users becoming attached to ChatGPT. Vallone did not respond to a request for comment. Cunningham left the economic research team last year, suggesting OpenAI was straying from impartial research to focus on work that promoted the company. His departure was first reported by Wired. "The company is still making progress, but it is locked in a tight competition with Google and Anthropic, who have consensus stronger models, so they have less of a luxury to slow down because they could let competitors push ahead," said a former employee."
Multiple senior researchers left OpenAI amid disputes over research direction and resource allocation. Tworek departed after seven years to pursue continuous learning and said appeals for computing power and staff were rejected, culminating in a stand-off with chief scientist Jakub Pachocki, who favored existing LLM architecture. Vallone left for Anthropic after being tasked with protecting users' mental health related to ChatGPT. Cunningham exited the economic research team, citing a shift from impartial research toward work promoting the company. A former employee noted tight competition with Google and Anthropic that could limit the ability to slow development.
