On April 2, 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.

BlockBeats previously reported that Sam Altman had stated on February 12 that he plans to launch GPT-4.5 and GPT-5 in the coming weeks or months. He also mentioned yesterday that a new open-source weight language model with reasoning capabilities would be released in the coming 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 represents 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.
