Introducing Agent-Native: an open-source framework for building agentic apps. Agents love walls of text. But humans don't. An agentic app let's you interact with agents through a visual interface. Engage with agents visually, via text, or both at once. Now in beta.

How many times have you explained the same login flow to your coding agent? We kept doing that with every bug, so we turned the whole routine into skills. Now an agent picks up a bug report, reproduces it, fixes it, and hands us a tested PR to review. Here's how to set it up yourself, starting with one bug. builder.io/blog/build-an-age…

The least productive thing I can imagine doing is watching an agent work. But I still do it, because I'm never really sure if the agent understood what I wanted it to do. So I end up reading the tool calls and watching files change. I want to agree on what it's gonna build, leave it alone, and review what comes back. But an all-text plan that's several pages long just feels like homework, and it's easier to let the agent run, even if it wastes tokens, just so I can see the result. What I need is a better way to verify the plan and review the result, just at a glance. Something where I can see the layout or the API flow and point to the part that's wrong. Here's what I've been doing instead lately. builder.io/blog/stop-watchin…

GPT-6 and Opus 5.5 make highly autonomous work cheaper than ever That makes now a better time than ever to build an autonomous software factory Here's a deep dive on how we now automated 90% of our development with self-governing agent factories Steal our /factory skills:

Already have a hard time editing one video. Now need to try variants Great feature tho!
🚨 Huge update: YouTube just announced video AB testing, thumbnail generation & more. I’m here in the YouTube offices in New York… and they’ve just made their biggest update in years. Here’s the 3 changes I am most excited about + my take as a strategist running some of the biggest channels on youtube: 1. Video AB testing YouTube is going to allow you to upload three different versions of a video now (starting with shorts and then rolling out to more) and test them over a period to see which gets the best watch time. My take: I am so excited by this and it feels like something we’ve all wanted for years. How often are you stuck between two different intros, or two different ways of ending a video? Now having the ability to get real data back is insane. I am going to heavily use this with intros. 2. Dynamic thumbnail testing for different audiences YouTube will now actually dynamically test different thumbnails with different audience segments. Allowing you to have different packaging for your returning viewers vs casual/new. My take: This is very interesting. Current AB testing for thumbnails essentially helps you find the best thumbnail for the biggest majority of your viewers… but that isn’t the best thumbnail for every segment. A core viewer might click on something very different to a brand new viewer. I think this will allow creators to print more views and test new styles that previously might have never won in the test. 3. Thumbnail generation in YouTube studio Directly in your studio you will have an ‘ask studio packaging assistant’ that can analyze your video and past performance and generate thumbnails (and titles) for your video. My take: This one’s been coming. The interesting thing for me is that when presenting this, youtube said something very interesting: they will match your style. This is the hardest step when using most Ai thumbnail generators, so if they can pull this off… could change the game. Really excited to see how these new features work. Youtube shared that they will be tested and rolled out in the coming months.

Is Jev actually good at computer use, or are those videos all over twitter more fake (or highly misleading) demos? I put it to the test and the results surprised me:
