gm, yes you read that title right. Happy Sunday! In today's weekly Roundup, we got OpenAI's new coding tool, Claude's new research tool, a new voice AI, Google's Dolphin AI, and a trending forum post about poop.

Google’s newest AI project isn’t trying to pass the bar exam or write your emails. It’s trying to talk to dolphins.

DolphinGemma is a lightweight 400M-parameter model built to decode the squeaks, whistles, and clicks of Atlantic spotted dolphins. It’s part of a wild collaboration with the Wild Dolphin Project and Georgia Tech, and it runs on Pixel phones. Not to generate selfies, but to analyze dolphin sounds in the ocean. In real time. From a boat.

It works kind of like a language model. The AI listens to dolphin sounds and tries to predict what might come next. Like autocomplete, but for underwater whistles.

Even weirder? They’re testing two-way communication. Dolphins are trained to associate certain sounds with objects, and when they mimic those sounds back, the AI translates it. Basically, if a dolphin wants a toy, it can ask for it. Which is adorable and also mildly terrifying.

In this week’s Maker’s Corner, Matt Carroll shares how he used humor to quietly market something serious. His project, Purposeful Poop, lets you log every bathroom trip — a joke at first glance, but it turned into a surprisingly effective funnel for his real product, My Financé, a personal finance tool.

He talks about launching the app in just five days, obsessing more over shareable OG images than features, and using the project to test a personal theory: that funny and useful can coexist — and convert. No viral moment, no flashy growth hack, just a creative way to get attention without hating himself in the process.

Matt’s in the thread talking about fast launches, honest marketing, and why building something small and silly can sometimes lead to bigger things.
