Google officially released its flagship AI model, Gemini 4 Argon, on Wednesday. However, despite the model achieving leading scores in multiple benchmark tests, some Google insiders reportedly expressed reservations about its actual performance in areas such as coding capabilities, believing its effectiveness was significantly discounted, according to Bloomberg. Google denied these doubts, stating that claims of Gemini 4's underperformance are "inaccurate." Analysts point out that Gemini 4's actual performance has a direct impact on Google's search, advertising, and cloud businesses. Following the news, Alphabet's after-hours gains narrowed significantly.
