Deepseek v4.1 is SCARY GOOD!

So, Chano just dropped Deepseek V41 Flash, and this is a new version of Deepseek Flash. I've already tested it out today. I want to show you what we've created and how it's worked so far. So, let me show you a couple of examples here. We actually built this using a combination of Deepseek V41 Flash with Deepseek Agent Harness. So, this is like a 3D game that we've created earlier before. And look at the quality of this stuff. Like, one thing that actually blows me away when it comes to this whole system is like the graphics, it almost looks like a frontier level creation, but this was done using Deepseek V41 Flash, which just dropped 24 hours ago. The other thing that blew me away when I was testing this out is that it was actually built very, very quickly. We built out like five projects side by side in the space of about 10 minutes. It is unbelievably fast, plus pretty good. Now, I wouldn't say, you know, it's like Deepseek level, but one thing I will say is that you can actually get, sorry, I wouldn't say it's a GPT-6 Astra level. One thing I will say, though, is that you can actually get GPT-6 Astra to orchestrate it for you. So let me show you an example of how this works and how you can get it working. So you can see over here, we have Deepseek harness built into our Gentigo S. And I would say that is the best way to use this directly. And then you can see here, we can select between Deepseek V4 Flash, 4.1 Flash and Deepseek V4 Pro. Now V4 Pro is really good as well.
But 4.1 Flash is definitely holding its own. Let me show you some other examples of stuff we've created here. So this was a website that we created.
As you can see, one of the things that I'll say straight off the bat is like it doesn't feel like AI slot, if that makes sense. Like if you look at the look and feel and the design of this website, it doesn't look like it was generated with AI. And this is just an example, as you can see here, it's kind of like a 3D style website that's been created and looks super nice.
All these images are kind of 3D as well, and they follow you around a little bit. And this was actually built using some custom design skills that we give away inside the AI Profit Boardroom. Link in the comments description or go to the aiprofitbomb.com. But the main thing that I'll say here is like for web design, for game design, et cetera, not only is it super fast, but actually does a decent job. Here's another example. So this is called Focus Desk. This is a productivity tool that we created using the system. And you can see here, we can start the focus session. We can reset it. We can run a break. We can set how long we want to focus for. And this was just built perfectly straight off the bat, which is pretty amazing. So we've also got, for example, a momentum tracker here. So it tracks how long we've been tracking our productivity. The design is quite nice as well. And then we have a to-do list over here. It's like an all-in-one productivity tool where you can import tasks, you can export tasks, you can clear all of your tasks, and you can have like a pomodoro timer on there as well. Like literally all of this was built side by side using Deepseek Harness, which is unreal to me. And then finally we have something called a flight deck, which is kind of just like a fun mission control system that we built, as you can see right here. It's kind of like a mission control directly for Deepseek Harness. And that was built all side by side. Pretty nice. So if you're wondering, okay, where do you get started with this?
What you can do is, first thing you want to do is just make sure that you have Deepseek Harness installed, which is a really, really cool harness if you've never tested it out before. I'll show you what that looks like in a second.
So if we go over here, you can see that we've got Deepseek Harness. This is a free open source, agentic harness. It's kind of like Claude Code or, for example, Hermes Agent. And that is what's recommended to run Deepseek. Obviously, it's created by Deepseek, and it's designed for running Deepseek models to get optimal performance out of them. Once you've done that, then, as you can see inside our agentic OS system, you can see here that we have Deepseek Harness ready to go. And what you can see here is that we need to make sure we have an API and the right models plugged in. So we've got Deepseek plugged in as an API key. So you want to get the API key from Deepseek and plug that directly into this system. It does run on the API, just bear in mind. So you do need a paid API key for that, but I think it's worth it. It's pretty fast.
