“We actually finished training GPT-IV in August last year, but we waited a little while before releasing it. When we first tried it out, we were all quite flabbergasted by how powerful it was, and we decided to sit on it almost six months to make sure that it was safe and ready for prime time.”

The claim, plainly

OpenAI finished training GPT-4 in August 2022 and withheld its release for nearly six months to conduct safety testing.

a quote alone can be ambiguous, so this restates it with the references and context of the conversation around it resolved. AI-written; the tape below the player is the source.

Assessment

Both legs of the claim are explicitly confirmed by OpenAI's official technical documentation. In the GPT-4 System Card and Technical Report (published March 2023), OpenAI stated that the model finished training in August 2022. Additionally, in the official launch announcement on March 14, 2023, OpenAI confirmed that it spent six months iteratively aligning, adversarially testing, and evaluating the model prior to public deployment.

OpenAI's GPT-4 System Card (March 2023) and Technical Report (arXiv:2303.08774) state: 'Since it finished training in August of 2022, we have been evaluating, adversarially testing, and iteratively improving the model and the system-level mitigations around it.'
OpenAI's official GPT-4 announcement on March 14, 2023, stated: 'We’ve spent 6 months iteratively aligning GPT-4 using lessons from our adversarial testing program as well as ChatGPT...'
