挑戰Chrome霸主地位！Perplexity AI積極進攻手機預裝
由輝達 (NVDA-US) 投資的 AI 新創公司 Perplexity AI，正積極與行動裝置製造商洽談，計畫將其新推出的 Comet AI 瀏覽器預裝在智慧型手機上，挑戰 谷歌 (GOOGL-US) Chrome 在行動瀏覽器市場的長期主導地位。 Comet 瀏覽器於 7 月 10 日正式亮相，其核心功能包含預裝的 Perplexity AI 搜尋引擎，能夠基於搜尋結果即時生成 AI 摘要，同時配備隨瀏覽器同步運作的 AI 代理程式 Comet Assistant。 這款瀏覽器不僅能將 Perplexity 的 AI 功能直接整合至網頁瀏覽體驗中，更允許使用者針對個人資料（如電子郵件、行事曆、瀏覽歷史）進行提問，甚至執行安排會議、總結網頁內容等複雜任務。 廣告 廣告 Perplexity AI 執行長斯里尼瓦斯（Aravind Srinivas）指出，儘管說服行動原始設備製造商（OEM）將預設瀏覽器從 Chrome 替換為 Comet 充滿挑戰，但預裝策略對於推動用戶更習慣性地使用其 AI 工具至關重要。 根據 Statcounter 的數據，截至上個月，Google Chrome 佔據行動裝置市場約 70% 的市佔率，而蘋果 Safari 和三星瀏覽器合計約佔 24%。 廣告 廣告 目前，Comet 瀏覽器仍處於測試階段，僅支援桌面端。Perplexity 計劃在數十萬初期測試用戶試用並穩定桌面版後，於明年將目標用戶群逐步擴大至「數千萬至數億」。這一策略性舉動，反映了整個產業正朝向具備智慧代理 AI 功能的瀏覽器轉變，這類瀏覽器僅需極少的人工干預即可做出決策並完成特定任務。 Perplexity AI 此前也曾與三星電子和蘋果進行洽談，期望將其 AI 搜尋功能整合到這些公司的設備中，以增強 Bixby 和 Siri 等語音助理的功能。 廣告 廣告 今年稍早，Perplexity AI 完成了一輪五億美元的融資，公司估值達到 140 億美元，主要投資者包括 Accel、輝達、亞馬遜創辦人貝佐斯，以及 Google 前 CEO 施密特。 更多鉅亨報導 •蘋果逆勢走跌 收購Perplexity可能成轉機？ •蘋果傳考慮收購Perplexity AI！為剝離與Google的合作做準備？

China's DeepSeek closes in on US rival OpenAI, surpasses Alibaba with upgraded model
Chinese artificial intelligence (AI) start-up DeepSeek said R1-0528, the first significant upgrade to its R1 reasoning model that debuted in January, matched the performance of top global competitors, including OpenAI and Google. Advertisement In a statement released late on Thursday, DeepSeek highlighted improvements in the new model's reasoning and creative writing capabilities, making it more adept at crafting argumentative essays, fiction and prose in styles that closely mimic human authors. Coding capabilities have also been enhanced. The company said the latest version achieved a 50 per cent reduction in 'hallucinations' – instances where AI generates misleading information with little factual basis. These upgrades were achieved by investing additional computing resources in the post-training stage, when developers make final adjustments and enhancements to the model after the main training process, the company said. Post-training usually focuses on boosting efficiency and enhancing content safety and accuracy. 'The updated R1 model excelled among domestic AI models in a range of benchmark tests, including maths, coding and general logic, and matched up to global top models such as [OpenAI's] O3 and [Google's] Gemini2.5-Pro,' DeepSeek said. Benchmark results cited by DeepSeek shows that R1-0528 outperforms Alibaba's Qwen3 AI model.

The shift underscores the heated competition among Chinese tech players in advancing AI capabilities.
