On Thursday, Meta unveiled early versions of its Llama 3 open-weights AI model that can be used to power text composition, code generation, or chatbots. It also announced that its Meta AI Assistant is now available on a website and is going to be integrated into its major social media apps, intensifying the company's efforts to position its products against other AI assistants like OpenAI's ChatGPT, Microsoft's Copilot, and Google's Gemini.

Like its predecessor, Llama 2 , Llama 3 is notable for being a freely available, open-weights large language model (LLM) provided by a major AI company. Llama 3 technically does not quality as "open source" because that term has a specific meaning in software (as we have mentioned in other coverage ), and the industry has not yet settled on terminology for AI model releases that ship either code or weights with restrictions (you can read Llama 3's license here ) or that ship without providing training data. We typically call these releases "open weights" instead.

At the moment, Llama 3 is available in two parameter sizes: 8 billion (8B) and 70 billion (70B), both of which are available as free downloads through Meta's website with a sign-up. Llama 3 comes in two versions: pre-trained (basically the raw, next-token-prediction model) and instruction-tuned (fine-tuned to follow user instructions). Each has a 8,192 token context limit.

In January, Microsoft introduced a new key to Windows PC keyboards for the first time in 30 years. The Copilot key , dedicated to launching Microsoft's eponymous generative AI assistant, is already on some Windows laptops released this year. On Monday, Tom’s Hardware dug into the new addition and determined exactly what pressing the button does, which is actually pretty simple. Pushing a computer's integrated Copilot button is like pressing left-Shift + Windows key + F23 simultaneously.

Tom's Hardware confirmed this after wondering if the Copilot key introduced a new scan code to Windows or if it worked differently. Using the scripting program AuthoHotkey with a new laptop with a Copilot button, Tom's Hardware discovered the keystrokes registered when a user presses the Copilot key. The publication confirmed with Dell that “this key assignment is standard for the Copilot key and done at Microsoft's direction.”

F23

Surprising to see in that string of keys is F23. Having a computer keyboard with a function row or rows that take you from F1 all the way to F23 is quite rare today. When I try to imagine a keyboard that comes with an F23 button, vintage keyboards come to mind, more specifically buckling spring keyboards from IBM.

Microsoft said in January that 2024 would be the year of the "AI PC," and we know that AI PCs will include a few hardware components that most Windows systems currently do not include—namely, a built-in neural processing unit (NPU) and Microsoft's new Copilot key for keyboards. But so far we haven't heard a whole lot about what a so-called AI PC will actually do for users.

Microsoft and Intel are starting to talk about a few details as part of an announcement from Intel about a new AI PC developer program that will encourage software developers to leverage local hardware to build AI features into their apps.

The main news comes from Tom's Hardware , confirming that AI PCs would be able to run "more elements of Copilot," Microsoft's AI chatbot assistant, "locally on the client." Currently, Copilot relies on server-side processing even for small requests, introducing lag that is tolerable if you're making a broad request for information but less so if all you want to do is change a setting or get basic answers. Running generative AI models locally could also improve user privacy, making it possible to take advantage of AI-infused software without automatically sending information to a company that will use it for further model training.

Microsoft is debuting major updates to two of its Surface PCs today: both the Surface Pro 10 and the 13.5- and 15-inch Surface Laptop 6 are major internal upgrades to Microsoft's mainstream Surface devices. Both were last updated nearly a year and a half ago , and they're both getting new Intel chips with significantly faster integrated GPUs, upgraded webcams, the Copilot key , and better battery life (according to Microsoft's spec sheets).

The catch is that both of these Surfaces are being sold exclusively to businesses and commercial customers; as of this writing, regular people will not be able to buy one directly from Microsoft, and they won't show up in most retail stores.

These aren't the first Surface products released exclusively for businesses. Microsoft introduced a new business-exclusive Surface Go 3 tablet last fall, and a Surface Pro 7+ variant for businesses in early 2021. It is, however, the first time Microsoft has introduced new versions of its flagship tablet and laptop without also making them available to consumers. You can find some of these business-only PCs for sale at some third-party retailers , but usually with extended shipping times and higher prices than consumer systems.

Microsoft has hired Mustafa Suleyman, the co-founder of Google’s DeepMind and chief executive of artificial intelligence startup Inflection, to run a new consumer AI unit.

Suleyman, a British entrepreneur who cofounded DeepMind in London in 2010, will report to Microsoft chief executive Satya Nadella, the company announced on Tuesday. He will launch a division of Microsoft that brings consumer-facing products, including Microsoft’s Copilot, Bing, Edge, and GenAI under one team called Microsoft AI.

Nadella said in a statement on Tuesday: “I’ve known Mustafa for several years and have greatly admired him as a founder of both DeepMind and Inflection, and as a visionary, product maker and builder of pioneering teams that go after bold missions.”
