Hello, welcome to the Last Week in AI podcast. We can hear, chat about what's going on with AI. As usual, in this episode, we will summarize and discuss last week's most interesting AI news.
I'm one of your regular co-hosts, Andrey Kurenkov. I studied AI in grad school and now work at the startup Aspergate.

**Jeremie Harris** (0:28)
I'm your other co-host, Jeremie Harris. I'm wearing a hat because I got back from taking my daughter to the park. What? And yeah, actually I'll be away, by the way, for the next episode, because I'm on a trip to the States doing a bunch of AI security stuff. But I'm excited to do this one. We punted the recording from Wednesday this week. We're now recording on Saturday, and we were just talking about how a bunch of stuff came out in the interim, which is really great. Challenging a little bit, because the way my schedule works out, I'm not able to spend the same amount of time between Wednesdays and Saturdays. So I'll be a little lighter on the details for some of these things, but I've still tried to prepare a bunch of material for it. So be warned, Andrey is going to be carrying some of the weight for some of the more recent releases, but hell of a lot happened.

**Andrey Kurenkov** (1:11)
Yeah, it's one of these things where it's like a thing in the AI industry where we get waves of releases, because I guess everyone wants to be one-upping each other, and everyone kind of knows when each other's stuff is about ready to go. So everyone just sort of preps their releases and announcements, and then they just do it around the same time. And that's exactly what happened in this episode. We'll be talking about GBA 5.6, we'll be talking about Grok 4.5, Muse Spark 1.1, a few other models on top of that. And beyond that, the big story, I think will be in policy and safety with some new vehicle research from Anthropic, and a new kind of major think piece from AI 2040 So it should be a good mix of content in this episode.
We'd like to thank Box for sponsoring us. Box is building the Intelligent Content Management Platform for the AI era, serving as a secure, essential context layer for Box's AI agents to access the unique institutional knowledge that makes a company run. And that's the key idea. The power of AI doesn't come from the model alone. It comes from giving AI access to the right enterprise content. Box's recent state of AI in the Enterprise Report found that 96% of organizations, say agents need access to company-specific content, but only 36% have connected the agents to trusted content across many use cases. And that trust bit is very important. Box is built of security, compliance, governance, and threat protection in mind, so employees and agents only access the information they're authorized to use. If you're thinking seriously about adopting AI in your company, think beyond the model. Your business lives in your content, and Box can help you bring that content securely into the AI era.

We'd like to thank Notion for being a sponsor. With the recent launch of Custom Agents, Notion became the collaborative AI workspace where teams and agents work side by side. And now their new developer platform is turning that workspace into infrastructure developers can build on. The platform gives developers and coding agents the ability to extend beyond what's possible on Notion by connecting to external systems, bringing context in, taking actions across your tool stack, and exposing Custom Agents capabilities to any system that needs them. Teams can use it to sync any data source into Notion, build any tool for your Notion agents, and orchestrate any agent in Notion via things like the CLI, Notion hosted sandboxes to run custom code with workers, an external agent API, and an agent SDK. It makes it so the workspace and the platform you build on are the same thing, and Notion is already built for teams. It has permissions, context, visibility, and governance from day one. Learn more about Notion's developer platform today at notion.com/lwai.
That's all lowercase, notion.com/lwai to try Notion's developer platform today. And when you use our link, you're supporting our show, notion.com/lwai.

Some routines live or die by how easy they are. And honestly, if something takes too much effort, I'm out. That's why Groons is my go-to. It's my one daily pack of gummies covering my greens, vitamins and minerals. Plus it has six grams of prebiotic fiber, which is more than two cups of broccoli. No mixing powders, no giant pills, no hassle. I just rip open the pack and I'm done. They taste good and they make it easy to stay on top of my health, even when life gets busy.
