The city of San Francisco has opened a complaint and launched an investigation into a giant “X” sign that was installed Friday on top of the downtown building formerly known as Twitter headquarters as owner Elon Musk continues his rebrand of the social media platform.

City officials say replacing letters or symbols on buildings, or erecting a sign on top of one, requires a permit for design and safety reasons.

The X appeared after San Francisco police stopped workers on Monday from removing the brand's iconic bird and logo from the side of the building, saying they hadn't taped off the sidewalk to keep pedestrians safe if anything fell.

Any replacement letters or symbols would require a permit to ensure “consistency with the historic nature of the building” and to make sure additions are safely attached to the sign, Patrick Hannan, spokesperson for the Department of Building Inspection said earlier this week.

Erecting a sign on top of a building also requires a permit, Hannan said Friday.

“Planning review and approval is also necessary for the installation of this sign. The city is opening a complaint and initiating an investigation,” he said in an email.

Musk unveiled a new “X” logo to replace Twitter’s famous blue bird as he remakes the social media platform he bought for $44 billion last year. The X started appearing at the top of the desktop version of Twitter on Monday.

Musk, who is also CEO of Tesla, has long been fascinated with the letter X and had already renamed Twitter’s corporate name to X Corp. after he bought it in October. One of his children is called “X.” The child’s actual name is a collection of letters and symbols.

On Friday afternoon, a worker on a lift machine made adjustments to the sign and then left.



Musk Launches 'Terafab' Project to Make Own AI Chips

Elon Musk announced Saturday a plan to make chips for artificial intelligence, robotics and data centers in space, in the latest bold project by the world's richest person.

The "Terafab", a manufacturing facility based near Austin, Texas, will aim to produce one terawatt of computing power per year, Musk said.

A terawatt is equivalent to one trillion watts. That is slightly less than the total power generation capacity of the United States, according to an industry group.

Musk said the project would be run jointly by his electric-vehicle firm Tesla and his rocket company SpaceX.

He did not disclose the initial investment. Previous US media reports have put the figure between $20 billion and $25 billion, AFP said.

Musk, who has no prior experience in semiconductors, said the Terafab was necessary because Tesla and SpaceX's demand for computing power was expected to far exceed that of global chip suppliers.

"We're very grateful to our existing supply chain, to Samsung, TSMC, Micron, and others... but there's a maximum rate at which they're comfortable expanding," Musk said.

"That rate is much less than we would like... and we need the chips, so we're going to build the Terafab."

An "advanced technology fab" in Austin will have the facilities to design, manufacture, test and improve each chip, Musk said.

Eventually, the project aims to make chips to support 100 to 200 gigawatts of computing power on Earth, and a terawatt in space.

Musk did not give a timeline for the Terafab's output, and has previously promised grand results from other projects on compressed time scales.

He said the Terafab would ultimately help humanity become a "galactic civilization" capable of harnessing the resources of other planets and stars.

Tencent launched a tool on Sunday to integrate its WeChat messaging platform with the OpenClaw agent, deepening its push into AI agents that have become a key battleground among China's technology companies.

The software, called ClawBot, will appear as a contact within WeChat, allowing users of China's most popular app with over 1 billion monthly active users to connect directly ⁠with OpenClaw, Reuters reported.

Users can send ⁠and receive commands to interact with the AI agent through the messaging interface.

The integration comes as OpenClaw, an open-source AI agent that can perform tasks such as transferring files and ⁠sending emails on users' behalf, has gained traction in recent weeks.

Users have rushed to install and experiment with agent products, prompting tech firms to explore business opportunities even as authorities warn of security risks.

Tencent's WeChat integration follows the company's launch earlier this month of its own AI agent suite, comprising QClaw for individual ⁠users, ⁠Lighthouse for developers and WorkBuddy for enterprises.

Last week, Alibaba launched Wukong, an artificial intelligence platform for enterprises that coordinates multiple AI agents to handle complex business tasks including document editing and meeting transcription within a single interface.

Baidu quickly followed with a series of AI agents built on OpenClaw, spanning desktop software, cloud services, mobile tools and smart-home devices.

OpenAI will begin showing ads to all users of the free and Go versions of ChatGPT in the United States in the coming weeks, a company spokesperson said in an emailed statement to Reuters.

The move was ‌first reported ‌by The Information.

OpenAI has ‌recently ⁠integrated Criteo, an ⁠advertising technology firm that provides an interface for buying ads and improving targeting, into its advertising pilot for the free and Go versions of ChatGPT in ⁠the US, Criteo said in ‌a statement earlier ‌this month.

Criteo has been pitching advertisers ‌on committing between $50,000 and $100,000 ‌in spending, according to The Information.

OpenAI has also advised advertisers that supplying more variations of ad text and ‌visuals can increase how often ads are shown and improve ⁠performance, ⁠the Information added.

OpenAI has been exploring advertising as a new revenue stream as usage of ChatGPT has surged, Reuters has reported.

The company is seeking to diversify revenue as it faces rising costs for computing infrastructure amid intensifying competition in generative AI.
