美國AI熱潮:數據中心激增

美國的AI熱潮一圖看盡

要展示美國的AI熱潮,其中一個方法就是觀察數據中心的數量。截至今年三月,根據Apollo的2025經濟展望報告,美國擁有5,381個數據中心,這個數字超過所有其他國家的總和。這些支出主要來自於像Apple、Microsoft、Meta和Amazon等被稱為「壯麗七巨頭」的公司。這四家公司合共預計今年在與AI相關的資本支出上將花費2000億美元。

Marques Brownlee捕捉到OpenAI的訓練過程

本週,OpenAI推出了首個公開版本的Sora——其AI視頻生成工具。Sora能夠根據文本提示生成令人印象深刻(有時甚至有些詭異)的短視頻。在評測最新版本的Sora時,科技影響者Marques Brownlee在玩這個工具時,要求它製作一段描述科技評論者談論智能手機的視頻,這正是他為其1900萬YouTube訂閱者所做的事情。

Brownlee注意到生成的視頻中出現了一個顯著而熟悉的假植物,正好放在AI生成的評論者的桌上,這與他自己視頻中出現的植物非常相似。

「我的視頻是否在那個資料來源中?這個植物是否是資料來源的一部分?這只是巧合嗎?我不知道。」Brownlee在他的評測中這樣說。

OpenAI的Sora系統卡片表示,它是基於「多樣化數據集」進行訓練的,包括「選定的公開可用數據,主要來自行業標準的機器學習數據集和網絡爬蟲」。

這個團隊決定他們的AI是否能用來殺人

當OpenAI、Meta或Anthropic等AI公司完成一個新的AI模型訓練後,過程中的最後一步之一是將模型交給「紅隊」——這些專家來自生物學、核武器、網絡安全和虛假信息等領域,他們的任務是讓模型做出非常糟糕的事情。

《華爾街日報》對Anthropic的內部紅隊進行了專訪,該團隊根據測試結果分配風險評分,並用於決定一個模型是否安全發布。報導提到:

「在Anthropic開始最新一輪安全評估近兩周後,Graham臉上露出了合格的鬆口氣的微笑。新的Sonnet 3.5已接近公司設定的危險能力門檻,但尚未突破紅線。」

眾多公司都在瞄準Nvidia的王國

據《資訊報》報導,Apple正與Broadcom合作開發自己的AI芯片——這是人工智能的關鍵組件。這一消息發布不久後,Amazon也詳細說明了其自家AI芯片的計劃。報導指出,Apple的這款芯片內部代號為「Baltra」,主要用於內部,並可能在2026年準備好進入量產。

這一切對於一直在芯片市場佔據主導地位的Nvidia來說,可能不是好消息,但對其他公司來說卻可能是好消息,因為渴望AI的科技公司之前一直在爭搶Nvidia所能生產的有限數量的芯片。

iPhone的新按鈕有其原因

Apple的人工智能逐漸變得更加智能。今天,這家iPhone製造商推出了18.2版本的軟件更新,為最新的Apple iPhone型號添加了多項長期待望的AI功能。這些功能包括:
– ChatGPT集成,雖然顯然不是每個問題都能讓Siri選擇使用ChatGPT。
– 使用文本提示和你的想像力創建自定義表情符號,稱為Genmoji。
– 視覺智能(僅在iPhone 16可用)。那個新的相機控制按鈕其實是有用的:如果你把相機對準某物並按住按鈕,你可以詢問它或在線搜索。

Apple Intelligence現在新增了Image Playground、Genmoji等功能。

這些發展顯示出AI技術的迅猛進步,特別是在消費電子產品中,這不僅提升了產品的功能性,也改變了用戶的互動方式。隨著越來越多的公司加入AI競賽,未來的科技產品將可能變得更加智能化,這對於消費者來說無疑是一個好消息。然而,這也引發了對數據隱私和安全性的擔憂,企業需要在推進技術的同時,確保用戶的數據不被濫用。

Using the uploaded photo generate ​a Monochromatic portrait, low-key lighting, chiaroscuro technique, striped shadows crossing the face, intense gaze, film noir aesthetic, studio lighting, sharp edges, depth of field."
​"Close-up, dramatic split lighting combined with linear shadows, black background, glossy lips and subtle skin texture, photorealistic digital art, professional portrait photography. Create a sticker set maintaining 100% of the woman's original facial features from the provided image. Do not alter the face, focusing on ultra-realistic details of the facial structure, eyes, eyebrows, nose, mouth, and expression. The final face must be realistic, not cartoon-like. She has long, voluminous hair.
1. Makeup:Maintain Original Face: We will preserve the structure of your face, eyes, eyebrows, nose, mouth, and expression as closely as possible to the original image to maintain naturalness and uniqueness, while adjusting the tone to be softer:

Eyes: Slightly reduce the sharpness of the Cat Eye eyeliner to a thin line close to the lash line for a softer look, while still maintaining eye definition.
Eyeshadow: Use natural tones like light brown, peach, or beige.
Eyebrows: Original shape, but brushed up to look softer and more natural.
Lips: Glossy, pink-tinted, nude-pink, or coral-toned lipstick/tint to make the lips look full and moisturized. Focus on a bright but not overly intense look.
2. Hairstyle:Natural Voluminous Long Hair: Her hair is long and flowing, but the styling will emphasize natural volume and movement. Soft, natural waves.
3. Outfit:

Attire: A white open-back bodysuit paired with distressed, faded blue denim shorts. There is a message "Kunika" on the shirt.
Shoes: Elegant, simple open-toe flat sandals.
Accessories: Styled freely and fittingly for each scene.
4. Poses & Sticker Elements:Poses: Various poses such as waving, jumping, walking playfully, reading a book, holding up a sign, cheering with both hands, stretching, or making a celebratory gesture, to create a cheerful and friendly atmosphere.Decoration: Include elements like small rainbows, sparkling stars, clear bubbles, hearts, balloons, or light-colored dots to decorate and enhance the fun of each sticker scene.Style: Thin black border around the sticker. Use a modern, rounded 'Itim' style font for the text.Text: Add short emotional phrases written in a cute, beautiful script near the sticker (no speech bubbles/text boxes):

"Hello"
"Love you"
"Submitting work"
"Great"
"Got it"
"Thanks!"
"Wait a sec"
"Ready to care"
"Fight"
"Let's do it"
"So cute"

"Get well soon"
"555"
"You're welcome"
"HBD"
