San Francisco-based OpenAI hinted as much in an all-caps post on X that read: “LIVE5TREAM THURSDAY 10 AM PT.” While there appeared to be a typo in the first word of that announcement, many of those who posted comments got the hint that the misplaced “5” could be about GPT-5.

In a subsequent post on his personal X account, CEO Sam Altman did not address the speculation on GPT-5’s release, but said the live-streaming session would be “longer than usual, around an hour”.

The potential launch this week of GPT-5 – the latest iteration of the technology behind generative AI chatbot ChatGPT – would reflect a strong effort by OpenAI to finally release the product upgrade in the global market of large language models (LLMs), considering that GPT-4 was released in March 2023.

In the meantime, open-source models from Chinese start-ups like DeepSeek and MoonshotAI , along with those from mainland Big Tech firms led by Alibaba Group Holding , have seen increased adoption in the industry on the back of their low-cost appeal and innovative features.
