除此之外，Altman 還預告稱 OpenAI 將在未來幾個月內推出一款具備推理能力的開源大語言模型。這是繼 2019 年的 GPT-2 後，OpenAI 第一次重拾開源，而背後的原因可以說顯而易見了（望向 DeepSeek）。

Manus Unveils AI Research Features to Take on OpenAI Service
Chinese-founded startup Manus showed off a feature Thursday that speeds up research by assigning tasks to scores of AI agents working in tandem, touting its biggest update since its March debut. The function, called Wide Research, processes large numbers of data entries simultaneously by roping in multiple AI agents. It will be made available immediately for paid Pro customers with plans to roll out to other users gradually. Users will be able to perform some tasks that other similar tools like OpenAI's Deep Research could struggle with, Manus said, such as ranking the top MBA programs or comparing dozens of different products.

Nothing just snubbed its biggest market while defending Phone 3 price
C. Scott Brown / Android Authority TL;DR Nothing has defended criticism about the Phone 3's price by saying that the device isn't meant for every region. Specifically, a Nothing spokesperson told Bloomberg that the company's largest market isn't the core focus for Phone 3 — a statement fans might find problematic. The company also noted it has no plans to lower the price of the device. The Nothing Phone 3 is proving to be divisive by design…literally. Its offbeat camera layout, new Glyph Matrix, and a price tag that stretches way beyond previous Nothing phones have made the Phone 3 a talking point across tech forums and comment sections. And while strong reactions to Nothing's products aren't anything new for the Carl Pei-led startup, the company's latest statement about who the Phone 3 is really for is a bit concerning. In response to rising complaints about the Phone 3's price, a Nothing spokesperson told Bloomberg that the company has 'no plans to lower the price' of the device and that its margins are key to sustaining investment. Then came the kicker: The spokesperson said that the majority of the cost complaints are coming from users in India, but that the region 'isn't the core focus market' for the Phone 3. The spokesperson went on to say, 'We've designed our product portfolio with different price points to serve different regions, and we have other offerings in the range that are more India-focused.' For a market that consists of Nothing's largest user base and the market where it has seen the fastest growth in the last two years, the statement feels a bit dismissive. As per Counterpoint Research, Nothing just recorded a 146% year-on-year increase in shipments in the region in question for Q2 2025, marking its sixth straight quarter as the fastest-growing smartphone brand there. This growth has largely been driven by the success of the impressive CMF Phone 2 Pro and Nothing's expanding offline presence. But while the brand's more affordable lineup is clearly resonating with buyers, the Phone 3, its first self-admitted 'true flagship,' has received criticism for not delivering a premium experience comparable to the Galaxy S25 series or the Pixel 9 lineup. Instead of addressing the criticism about pricing and positioning, the company, which is known for being community-focused, has taken a noticeably defensive tone. CEO Carl Pei also recently took to YouTube to respond to Phone 3 reviews. 'I don't know why people are so emotional about a phone design,' he said. 'Either you like it or you don't like it. And if you don't like it, just move on.' He added that while it's heartening to see how invested the community is, things may have gone too far: 'We have colleagues who are getting harassed now for the design.' There's no doubt that online criticism can sometimes cross lines, and harassment of any kind should not be acceptable. But it's equally important for companies to hear out and consider legitimate consumer concerns. Saying a major market 'isn't the focus,' especially when it accounts for the bulk of your brand's growth, could be seen as sending out the wrong message. It's also notable that the iPhone 16 has come out on top as the most shipped device in India this past quarter, signaling that flagships are very much in demand in the country. As per Counterpoint, the ultra-premium price segment grew 37% year-over-year in India. So really, Nothing's statement implies that criticism from a large segment of its user base doesn't matter, or worse, that these consumers aren't worthy of the flagship experience at all. While it's Nothing's perogative to design different products for different markets, because it's a business at the end of the day, it's a little out of character to see that a brand that's always positioned itself as one that listens to its users is telling a huge chunk of its fan base that its latest product isn't meant for them.

AI Demand At the same time, Meta raised the lower end of its range of forecasts for its 2025 capital expenditures to $66 billion to $72 billion, up from $64 billion to $72 billion previously. Wall Street now expects that Meta will spend $100 billion in capital expenditures in 2026, significantly ahead of previous forecasts. Nvidia's microchip sales might also receive a boost from 'Stargate Norway,' a project that involves a partnership between OpenAI and AI infrastructure company Nscale and Norwegian industrial company Aker (DE:FKM). The project reportedly plans to use 100,000 of Nvidia's graphics-processing units (GPUs) by the end of 2026. NVDA stock is now up 35% this year. Is NVDA Stock a Buy? The stock of Nvidia has a consensus Strong Buy rating among 38 Wall Street analysts. That rating is based on 34 Buy, three Hold, and one Sell recommendations issued in the past three months. The average NVDA price target of $185.79 implies 2.60% upside from current levels.
