In his recent tweet, Altman has confirmed that the next iterations in the GPT series, namely GPT-4.5 and GPT-5, are on the horizon. This news has generated considerable buzz, particularly against the backdrop of recent tensions involving key figures like Elon Musk. According to Altman's announcement, GPT-4.5, previously referred to as "Orion," is slated for imminent release. This model will mark the last of OpenAI's "non-chain of thought" models, indicating a shift towards more advanced reasoning capabilities integrated into a unified language model.
