Hey all, Alex here, coming to you from the (surprisingly) sunny Seattle, with just a mind-boggling week of releases. Really, just on Tuesday there was so much news already! I had to post a recap thread, something I do usually after I finish ThursdAI! From Anthropic reclaiming close-second sometimes-first AI lab position + giving Claude the wheel in the form of computer use powers, to more than 3 AI video generation updates with open source ones, to Apple updating Apple Intelligence beta, it's honestly been very hard to keep up, and again, this is literally part of my job! But once again I'm glad that we were able to cover this in ~2hrs, including multiple interviews with returning co-hosts ( Simon Willison came back, Killian came back) so definitely if you're only a reader at this point, listen to the show! Ok as always (recently) the TL;DR and show notes at the bottom (I'm trying to get you to scroll through ha, is it working?) so grab a bucket of popcorn, let's dive in 👇 ThursdAI - Recaps of the most high signal AI weekly spaces is a reader-supported publication.

Claude's Big Week: Computer Control, Code Wizardry, and the Mysterious Case of the Missing Opus Anthropic dominated the headlines this week with a flurry of updates and announcements. Let's start with the new Claude Sonnet 3.5 (really, they didn't update the version number, it's still 3.5 tho a different API model) Claude Sonnet 3.5: Coding Prodigy or Benchmark Buster? The new Sonnet model shows impressive results on coding benchmarks, surpassing even OpenAI's O1 preview on some. "It absolutely crushes coding benchmarks like Aider and Swe-bench verified," I exclaimed on the show. But a closer look reveals a more nuanced picture. Mixed results on other benchmarks indicate that Sonnet 3.5 might not be the universal champion some anticipated. My friend who has held back internal benchmarks was disappointed highlighting weaknesses in scientific reasoning and certain writing tasks. Some folks are seeing it being lazy-er for some full code completion, while the context window is now doubled from 4K to 8K! This goes to show again, that benchmarks don't tell the full story, so we wait for LMArena (formerly LMSys Arena) and the vibe checks from across the community. However it absolutely dominates in code tasks, that much is clear already. This is a screenshot of the new model on Aider code editing benchmark, a fairly reliable way to judge models code output, they also have a code refactoring benchmark Haiku 3.5 and the Vanishing Opus: Anthropic's Cryptic Clues Further adding to the intrigue, Anthropic announced Claude 3.5 Haiku! They usually provide immediate access, but Haiku remains elusive, saying that it's available by end of the month, which is very very soon. Making things even more curious, their highly anticipated Opus model has seemingly vanished from their website. "They've gone completely silent on 3.5 Opus," Simon Willison (𝕏) noted, mentioning conspiracy theories that this new Sonnet might simply be a rebranded Opus? 🕯️ 🕯️ We'll make a summoning circle for new Opus and update you once it lands (maybe next year) Claude Takes Control (Sort Of): Computer Use API and the Dawn of AI Agents (𝕏) The biggest bombshell this week? Anthropic's Computer Use. This isn't just about executing code; it’s about Claude interacting with computers, clicking buttons, browsing the web, and yes, even ordering pizza! Killian Lukas (𝕏), creator of Open Interpreter, returned to ThursdAI to discuss this groundbreaking development. "This stuff of computer use…it’s the same argument for having humanoid robots, the web is human shaped, and we need AIs to interact with computers and the web the way humans do" Killian explained, illuminating the potential for bridging the digital and physical worlds. Simon, though enthusiastic, provided a dose of realism
