The artificial intelligence community is buzzing again, this time focusing on rumors about the possible upcoming release of GPT-4.5. AI developer Tibor Blaho discovered potential clues regarding a 'Limited Preview' version of GPT-4.5 in the ChatGPT code, suggesting that OpenAI may plan to offer it first to Teams subscribers. This is not the first time rumors about GPT-4.5 have surfaced in the industry. As early as last March, discussions about this potential new model version were widespread. At that time, OpenAI's blog even...

Alexis Conneau, former chief researcher at OpenAI and head of the GPT-4o project, announced his departure to start a new company, sparking discussions in the AI community. Conneau revealed on social media that after the conclusion of his '#Her project' at OpenAI, he decided to launch a new venture. He humorously responded to inquiries about the timeline for Artificial General Intelligence (AGI), suggesting that the new company could bring about 'AGEI'.

OpenAI GPT-4 stands out on the Vectara leaderboard with only a 3% hallucination rate in document summarization and an accuracy rate of 97%. The Vectara evaluation reveals that GPT-4 Turbo and GPT-4 perform the best, followed by GPT-3.5 Turbo, while the highest-rated non-OpenAI model is Meta Llama. Vectara has released open-source models that can check the hallucination rate of language models to enhance the credibility of generative AI systems. Google's models performed moderately on the leaderboard.
