YouTube TV is rolling out a new feature aimed at live sports fans. Called “multiview,” it lets people watch up to four different streams at once. Just in time for March Madness, multiview is debuting in early access to select U.S. subscribers and only for sports content, YouTube says, adding that it’s exploring how to apply the quad-screen format across a variety of content and will gradually make it available to more users. Slow-walking the initial launch will allow the platform to collect feedback and improve the feature in time for the fall NFL football season. Read more

OpenAI has released GPT-4, which it says is a more powerful and reliable version of the artificial intelligence technology powering its viral ChatGPT chatbot. GPT-4 can analyze images and handle larger blocks of text and is generally “more creative and collaborative” than earlier iterations when it comes to things like composing songs, writing screenplays and mimicking a user’s authorial style. “GPT-4 can solve difficult problems with greater accuracy, thanks to its broader general knowledge and problem-solving abilities,” OpenAI says. GPT-4 is already driving the chatbot technology behind Microsoft’s Bing AI search engine, now in beta. Read more

The demand for artificial intelligence by enterprise as well as consumers is putting tremendous pressure on cloud service providers to meet the vast data center resources required to train the models and deploy the resulting apps. Microsoft recently opened up about the pivotal role it played in getting OpenAI’s ChatGPT to the release phase via its Azure cloud computing platform, linking “tens of thousands” of Nvidia A100 GPUs to train the model. Microsoft is already upgrading Azure with Nvidia’s new H100 chips and latest InfiniBand networking to accommodate the next generation of AI supercomputers. Read more

Google is readying an API and other enterprise tools for its Pathways Language Model (PaLM) — a large language model similar to GPT — to encourage developers to create chatbots and other apps using the platform. PaLM is one of Google’s most advanced systems, with the capability to generate text, images, code, video and audio from natural language prompts. Much like OpenAI’s GTP series and the LLaMA family from Meta Platforms, it is suitable for a wide variety of general tasks. To facilitate PaLM’s use for specific tasks, Google is launching the MakerSuite along with the PaLM API. Read more

A California appeals court upheld most of Proposition 22, the 2020 ballot measure impacting gig workers. The decision — a victory for Uber and Lyft, among the companies spending upward of $200 million to support the measure — overturned a 2021 California Superior Court decision that found the proposition “unenforceable.” The Service Employees International Union, party to the lawsuit challenging Prop 22, is expected to appeal to the California Supreme Court, which may hear or reject the case at its discretion. Either way, that result can then be appealed to the U.S. Supreme Court. Read more
