According to ChainCatcher, OpenAI founder Sam Altman stated that the new version of OpenAI might be delayed, currently facing computational power bottlenecks, and services may sometimes slow down.

Previously, Sam Altman mentioned on February 12th that he plans to launch GPT-4.5 and GPT-5 in the coming weeks or months. He also stated yesterday that he will release a "new open-source weight language model" with reasoning capabilities in the next few months. An open-source weight language model refers to a model that can be publicly used, downloaded, modified, or deployed. Although not as open as a fully open-source model, it is a significant change compared to the completely closed GPT-3 and GPT-4. OpenAI partially open-sourced the GPT-2 model in February 2019 and completed full open-sourcing in November of the same year.
