OpenAI officially released GPT4 on March 14, 2023. I'm now projecting the GPT 4.5 release date range for June-July 2023 (this is estimated). I've provided my forecasted GPT 4 release date here based on my observations of Sam Altman's comments about releasing it slowly. As a two decade plus web developer, I understand the basics of developing internet technology. There is a massive amount of testing and development that needs to be done so I think 6 months would be too earliest we would see GPT 4 released, which would be around May 30th, 2023. That's my early projection. My project for a delayed release would peg it around 12 months from the initial release of ChatGPT on November 30, 2022, which would mean Chat GPT 4's release is estimated to be around November 30, 2023. These are estimated dates. There is no official word from OpenAI on when the official GPT-4 release date will be announced.
