🚀 Today, we've open-sourced Rivet, a game-changer for #AI agents! We just launched our first AI agent at @ironclad_inc. But I almost gave up on it, until Andy build v0 of Rivet and showed me what was possible. Let us know what you think! rivet.ironcladapp.com

@ankrgyl Amazing! Big congrats to you and the team! 🚀

We sent this note to our customers to let them know that Braintrust has raised a new round of funding, and thank them for their support. While the money is exciting, our focus hasn't changed: we're building Braintrust to help our customers ship quality AI products. In 2026, AI is moving to production but teams have never had less conviction about what will fail next. Our customers are building AI products that serve millions and simply need to work. If Braintrust makes their lives easier and their products better, I know we are doing our job. Thank you to @ICONIQCapital for leading our Series B, and to @a16z, @GreylockVC, @basecasevc, and @eladgil for doubling down. Thank you to the Braintrust team for all the incredible work you've done over the past year. And thank you to our customers, who have made this growth possible.

Another Bridge pro crushed level 10! youtube.com/live/jxyiXod3p… #letsplay #indiegames

😱A Bridge pro just utterly destroyed Overtrick! twitch.tv/videos/2644365… Feels unreal to learn how to play your own video game from someone else! 😊

✅ Indie game devs and players met! ✅ Many overtricks attained! ✅ Tons of valuable feedback collected! I showcased Overtrick at the SF Holiday Indie Arcade Expo last night, alongside 14 other awesome indie teams. 10/10 event!

Do you like playing Bridge? Ever wish you could play without finding three other players? I did... and made a bit of a side-project out of it. So: Overtrick Devlog #1: Turning Bridge into a Single-Player Deckbuilder celloloops.itch.io/overtrick/devl… #indiegames via @itchio

🏆SPC x Anthropic Audience Choice: Claude is now a fully functional bartender! Hackababies built an AI powered (and autonomous) tiki bar in the SPC office. Built by @emilyyidan, @gogwilt, @zackary_a, & Crystal Mao

Can AI Agents do mixology? Absolutely! Had a blast building this LLM-powered tiki bar during the @southpkcommons @AnthropicAI hackathon. Probably some of the first AI-generated cocktails ever tasted, mixed by a robotic drink dispenser, with great banter voiced by @elevenlabs

Now THIS is vibe coding!

Vibe coding and websockets do not mix well.

"Into the Breach" might be the perfect new dad game. Mobile (and on Netflix!), so you can play wherever. Turn-based, so you can pause if baby starts fussing. Tiny, randomized levels, so the game stays interesting, but doesn't force your addled dad-brain to remember too much.

TikTok is back! Guess I can continue to fail my personal goal of going viral on TikTok.

@dougsafreno @rivet_ts Agent loops are way easier to build now than 18 months ago, though. The models are just better. So your point is well-taken. You probably don't need an agent framework like Rivet to get a basic loop. But you'll still run into issues Rivet solves as your agents get more complex.

@dougsafreno For us, Rivet provides iteration speed and debuggability, to a level code just doesn't. Even for non-agent loops, I'll use @rivet_ts from the outset.

Why do people use agent frameworks vs. a simple agent loop w/ access to tools?

@dougsafreno @GentraceAI @matrixvc Amazing news! Congrats @GentraceAI team!

Big news today: @GentraceAI raised our $8M Series A led by @MatrixVC. We’re celebrating by launching Experiments, the first collaborative testing environment for LLM product development.

@humanloop Congrats on the launch!!

Humanloop is now generally available! After 2 years of working closely with early customers, we're opening access to our full evals platform. 🧵 Here's what we've learned and how we can help you build great AI products:

It's launch day! 🚀

Gartner MQ Leader!! To my tech friends... this is a big deal! 😃 So, so proud of the team for getting us here. 🚀 Let's gooooo!
