Is GPT-5 on the cards? What might it look like?

livemint.com:

Maintaining that GPT-4 “kind of sucks", Open AI CEO Sam Altman said recently his company will release an “amazing new model" this year. This has sparked speculation that OpenAI may release GPT-5 sometime between June and August this year.

Why is this a big deal? OpenAI, the maker of ChatGPT, inadvertently published a blog post that was indexed by search engines Bing and DuckDuckGo. Readers on X and Reddit first spotted the page, which has since been deleted but the cached version hints at the release of GPT-4.5 Turbo with a “knowledge cutoff" of June 2024 (date when the AI model will stop being trained on information).

This has led many to believe that OpenAI will release GPT-4.5 Turbo this summer. When asked if GPT-5 is coming this year, Altman remarked: “We will release an amazing new model this year" but “I don’t know what we’ll call it." Released in 2023, GPT-4’s training data specifics and parameters were not disclosed but unlike GPT-3, it can accept both text and images as input and emit a text output (multimodal).

But it still cannot reason, plus it hallucinates (confidently gives wrong answers), and has resulted in a host of plagiarism and copyright violation suits. Launched in 2020 with 175 billion parameters, GPT-3 was a vast improvement over previous editions, with few shot learning (learnings from only a small number of labelled training data) but concerns remained over biases, hallucinations, and contextual understanding.
