In a bold move that caught the tech world’s attention, OpenAI chief Sam Altman unveiled fresh benchmark results claiming ChatGPT 5.6 has surpassed all rival language models to claim the title of “world’s best.” The announcement arrived amid a heated online exchange between Altman and Elon Musk, whose recent tweets reignited a long‑standing rivalry that has played out across platforms like X (formerly Twitter) and LinkedIn.
