Fable 5 Agentic OS is Insane... just watch

summarized

TLDR

The Fable 5 model powers a new 'agentic operating system' across five levels: integrating into the core OS, unifying memory into a single brain, orchestrating a 'Ministry of Agents' that debates queries across models, running autonomous 'dreaming' processes overnight for improvements, and adding an interactive voice interface. Jack Roberts demonstrates how to configure Hermes Agent to call Fable 5, connect Obsidian-based wikis, and build custom voice overlays, aiming to make AI assistants universally accessible and context-aware.

Key points

  • Fable 5 is described as the world's most powerful AI model and central to the new agentic operating system upgrade.
  • Level one is giving Fable 5 control over the OS to auto-discover and add underutilized skills with ROI tracking.
  • Level two, 'one brain', unifies memory from Claude chats, Hermes chats, and an Obsidian wiki so AI never needs repeated context.
  • Level three introduces the 'Ministry of Agents' where Fable 5 orchestrates multiple expert models (e.g., Deep Seek V4 Pro, GLM 5.2, GPT 5.5) and caches prompts for token efficiency.
  • Level four enables autonomous 'dreaming' where Fable 5 works overnight, reviewing all data to generate suggestions and improvements.
  • Level five adds an interactive voice interface built on top of the OS, allowing users to ask status questions and control the dashboard via voice.
  • Fable 5 can access everything stored locally (Claude chats, code-ex, anti-gravity) to form a 'beautiful lake of data' for personalization.
  • The system supports voice interaction with real-time dashboard changes (e.g., changing UI colors via voice command).

Fable 5 is the world's most powerful AI model and the most important thing that you're going to build this year is an agentic operating system. And in this video, I'm going to show you exactly the new capabilities that Fable 5 unlocks across five levels that is going to help you get more done, build faster than ever before, and even save money so you don't fall behind. And if you're new, I'm Jack Roberts. I built and sold my last tech startup with like a gazillion customers. Now I'm building my own AI startups and I share here the stuff that actually works. So if you haven't already, grab that beautiful coffee and let's dive straight in. So this is the Agentic operating system. And in this video, I'm going to show you the Fable 5 Aentic operating system across these five levels. But first of all, of course, when we're talking about Fable 5, we're talking about a new class of model. It is the best, most powerful model we have available. this graph, loads of lines moving in certain directions and lines going up is a good thing as we all know. People are saying, Jack, I just say the word Fable 5 and my credits disappear. I'm going to help you with that in this video as well. Really important, but the bottom line is that Fable 5 is insanely powerful and we're going to use that to massively upgrade our cla code operating system. Now, there's loads of reasons why you need a claentic operating system. Um, three of the big ones is unified memory. And once I show you these, you're going to understand it. So we can build these incredible five levels together. Having a memory that connects to everything. So whether you are doing things on a phone call somewhere, whether you're using Hermes agent or openclaw, it enables you to universalize your entire world in one location, which means that Hermes, it knows what's happening with Claude and Claude knows what's happening with Hermes. If you're on a different laptop, wherever you are, whatever the hell's going on, you have everything connected into one continuous system. That's why it's so so so important. The other thing is the fact that we can now have and I'm going to show you in this video as well what Claude called Fable 5 dreaming for us. You can have the world's most powerful model thinking about how it can make your life better based on everything that you've spoken to about it. So it can do this for you autonomously. And the reason why it's better than just having that in Claude is that Claude is great but it's one part of your life. You're using other softwares, other AIs. Maybe using chat GBT, maybe you're using Hermes. You should be using Hermes to some extent. Everyone should be. The idea is that no matter what's happening, we can get Claude called to look over everything and create suggestions and then we have one location to conduct our entire AI world. Now, this takes us very nicely onto what we call level one, which effectively is giving Claude Fable 5 the wheel. And by giving it the wheel, I just mean adding Fable 5 to our actual operating system. And what we're going to have it do first of all is to look at our entire world and find for his skills that we should be using that we're not. So what I'm going to do is I'm going to shoot over to the cla code operating system. Now there are many ways that we can access Fable 5. At the moment at the day at which you're watching this video, you may have one day left of using it inside the claude app. After that it's all API access. Now the harness that I'm going to be using to access this is Hermes agent. You can just yap it if you want to. Hermes though gives us an unbelievable additional amount of benefits that we get just by using it. So you can see down here I've got this model selector here, right? GPT 5.5. And this will change. I've got ministry. I'm going to show what that means later. It is so freaking powerful. GLM 5.2 Opus 4.8. I need to add in Claude Fable 5. So, how we're going to do that? I'm going to shoot over to Claude. Beautiful. Now, I'm inside the Claude desktop app, which you need your $20 a month subscription to get access to. So, I'm going to come down here for example, and I'm going to be selecting Fable 5 including until July 7th. Guys, they are tantalizingly teasing us here. So, I don't need Max. I'm just going to need low for this one. And effectively, what I'm going to do is the follow. Hey there, I want you to look at my cord code agentic operating system and in the hermy section where I can select the models I would like you to add for me Fable 5 and I would like you to add for me the effort dial and anything else that you think might be helpful or relevant in doing that. Go ahead and build that for me. Okay, going to send that one off. Now, actually on second thoughts, what I'm probably going to do here, guys, is come down and change this effort to probably a high if it's a build. It's going to come down here, send that one off, and then we're going to be able to rock and roll. And just like that, it's actually done its first version. So, let's come down and take a look at this. You can see now we've got Claude Fable 5 that has appeared. And we can even select the strength level from low, medium, high, extra high, which is fantastic. And then we've got commands. Beautiful. So, now I've loaded up. Let's put it to test. I'm going to scroll down into my Hermes agent. Click on GBT 5.5. By the way, you don't have to do this in Hermes. If Hermes is new to you, I'm going to put a link down below. You can go ahead and grab the Hermes master class that I'm just releasing. It goes through foundations, uh, setting up Hermes, powering Hermes, and also the Claude code masterass that will take you from a complete beginner to do everything like building websites, power features, memory system, Hermes, agent apps, you name it. I'll put it down below so you can become a pro in that. So, we're here. I'm going to go ahead and select Claude Fable 5 Frontier model. And we can do extra high, high, medium. Let's go for something like uh a medium. And I might say something like, "Hey there, dude. Could you tell me the last thing that I saved on my desktop? All right. Also, which model is this? Okay. So, we can double check that. I'm using Glad do speech to text. So, we can kick some butt and that Hermes is having a good think and we can get some answers. And then immediately we've got this last thing saved on your desktop with the five agent OS and you're doing core fab 5. Cool. So, the first thing that I wanted to do now essentially is help us understand what skills could we be using that we're not currently using. So, I'm going to come down and drop the actual strength level down to low, which is going to be fastest and light reasoning. And let's give it a command. Hey there, dude. I would like to look at all the data that you have available in this agentic operating system. All my claw chats, my Hermes chats, everything. And I want you to come back and suggest two skills that I could be using that I'm not currently using that would give me the greatest ROI based on all the information that you have for me. And if they're skills to external sources, let me know what they are. I'm going to send that one off and let it do his work. And what's really cool about this prompt, guys, is it does have access to everything. It has access to all the conversations I've added. Hermes, all the conversations I have in Claude because what you may not realize, but every chat you have in Claude, in anti-gravity, in codeex is all stored locally. So, we can use all of this this kind of beautiful lake of data to help refine and understand what skills we have. Also, and this is really important, bear in mind here that in the Aentic operating system, you're going to have a list of all of your skills. Here we even have ROI on the skills based on how much for example in our onboarding system which I have in a setup wizard here you can see it because when you download this it will go through basically showing you exactly how to set up your OS your name your photo etc etc and it actually identifies all the systems you have on your computer and one of the cool things that it does and this is really relevant for your school section like it even identifies memories and stuff like that. If I can come down here, you set what your hourly rate is. And then based on that, we can actually calculate how much your skills are saving you in dollars every single day. It's so cool. This onboarding itself took me like 3 or 4 hours to build. It's so freaking sick. So, and now we come back. Hermes is going to calculate, look at all the data, and give us some suggestions. And just like that, Fable 5 has come back with some pretty incredible suggestions. I blurred them out just for privacy sake, but this is nuts. One of the things I will say though is if you are getting Fable 5 to look at everything that can be token hungry. So just bear that in mind when you're asking questions and what you're asking it to do. But this is freaking amazing. It's gone through my skills and it's found ways of how I can improve things based on the models that I'm using and all the different systems. Now this does take us very nicely onto the second level of this which essentially is this idea of one brain. And let me show you what I mean. Now the one brain is the most powerful feature of having an agentic operating system and let me explain exactly what I mean by that. So this is the brain and this is the memory core. This represents the entire memory. Now the idea of the memory system here is that we want ultimate context because if AI had infinite context about you, what your business goals were, what your financial numbers were, what you spoke to about yesterday and a year ago and the meeting you had with Billy Bob and Susie Mcu days ago, they had all that information. You would never need to repeat yourself and you would always get the best insights from it. So one of the things that would do in aentic operating system is you want to link it with your obsidian bot. You want to link it with every one of your core code systems and you also want to link it with everything that's happening with your AI personal assistance like Hermes agent. So you come down, you can see you can connect this all together. Now one of the things that I want to do here is I actually want to go to essentially Fable 5 and say hey this is my memory system. What I want you to do is think of way how we could actually improve this and make it more interactive and maybe even easier to use so I can elevate the entire system because one of the great things about the Obsidian Ba and I'll put a link on screen if you're not familiar with what that is or how that works. You can get those Kapathy principles. But the idea is that you build a local LLM wiki that you can access with any information that you want to. And the key thing here is that both Claude and Hermes can access the same database and whenever you ask questions to it, it can draw from that wiki article. For example, I can come to my Agentic OS and say, "Hey, over to my Obsidian wiki and just remind me of three best principles for making YouTube videos in terms of intros. How I make great intros just as an example. In reality, you could have anything." And then just like that, we can see we've got this back here. Start with the payoff, not the setup. Open loop in the first 10 seconds. Cut everything that delays trust. So, this is very cool. It's got this all from my Obsidian wiki. And the cool thing I've got here as well is an overview of my token spend so I know exactly where I'm at in this conversation. So, we're going to give a prompt to Fable to actually improve our memory system. This is the prompt that we're going to give it. Hey there, I would like to go ahead and improve the memory system within my Claude code agentic operating system. It is connected to my Obsidian or my Hermes chats or my Claude code chats. I want you to find a way to make it interactive so that I can click through various different aspects, bring that knowledge out. I want you to be creative and add a section that will help me discover new facets about my knowledge and maybe we could categorize it and cluster it based on what the topics are. I'll give you free reign. I want you to build something interesting to elevate the memory system inside my agentic OS and then we'll just send this off. And so now Fable's actually completed. Let's go down and see what it's done for us here. So this is really interesting. So let me just pull this over so you can see a little bit better. Cool. So what I've got down here then I've got all of my different wikis. My obsidian wiki my YouTube and what basically Fable has done is organized it based on topic. So we have Callaway, Ed Lawrence, cool guy that lives out in Dubai talks a lot about YouTube strategy. Patty Galloway hooks YouTube. So it's these are the thing that the threads that come up more often. I can expand and see 15 more topics. Really freaking cool. So if I come down and I say I want to learn more about retention. So I click on retention and I have these different concepts and frameworks. Very cool. I can click into that further and get more information that links to intros. And now I'm back at intros and I've got business YouTube. I can click on this and I can keep clicking around. And by the way, I just gave it the prompt and it went ahead and did all of this. I've even got a search bar. I can search for things. If I go for I want to learn about hawks and look at this dynamically, guys. This is ridiculous. This is insane. This is retention. And now and it's like my own personal kind of database where I can look through all my memories. So you can see how Fable 5 is taking the kind of agentic memory system to a completely new level. But this takes us on to an even more powerful level with the Claude Fable Aentic OS and that is the Ministry. I called it Ministry of agents. Some say Jack it's mixture of agents. I'm saying hey Ministry is way cooler. What do I mean by that? Well let me show you exactly what it's about cuz this is really really important to understand. So if I come over to Hermes agent on the left hand side now this is a feature that Hermes released which is cool and it's in a few different models. You can do it in your agentic OS. If you come over to this Ministry of Experts model here, the idea of this is that you have an orchestrative agent, right? You have a model that is looking after everything. And what it does when you ask it any kind of question, building code, it could be about your life, like what coffee shop should I go to? Because we know guys, that's the most important question these days. What it will do is actually ask three separate models. So I've got here, for example, Deep Seek V4 Pro, GLM 5.2, to and chat GBT 5.5 which is extremely token efficient by the way and this whole system saves you loads of tokens and it will look at all the answers find out what the best ones are and then it will orchestrate and give you a way better response. So what we're going to do now is actually put in Fable 5 in the orchestrator RO because Opus 4.8 is no longer the king. So we're simply going to remove this guy right here and then we're going to find Fable 5. And since we can't see Fable 5 on the left hand side, we're going to go ahead and add it in by shooting over to Claude. So then come back over and explain to Claude that you want to add it in if you haven't done that yet. And literally you should add it into the Ministry of Experts. Of course, I've got it in mine. Beautiful. Simply come back over to the operating system. Come over to Ministry of Agents. And what we're going to do now is remove 4.8. And then we should be able to add in beautiful Fable 5. And here it is. Going to grab him and bring him over. So he's now going to be the orchestrator, which is fantastic. And then we're just going to save this to the computer. If you haven't actually added this before, all you do is literally come down, copy this, and just drop it in the chat window, which I will do up here. So, so you get a bit of visibility of how it works. And one of the cool reasons that we use Hermes for this chat, by the way, is because it actually caches the prompt for all of them. So, ordinarily, if you were to do what we call an adversarial review, in other words, you're going to have DeepC gives an answer, GLM gives an answer, GPT 5.5 gives an answer, they would all we'd have to pay for the tokens on all of them. But we actually use a cache which is going to save us so much in tokens. And obviously we're using open router for deepseek and GLM and charge GPT 5.5. We're using our aorth which is freaking amazing which means you actually pay pennies. It's so cheap. I'll put a link to the full system if you've never used this ministry of experts. But using Fable 5 in it is a crazy game changer. And as you can see it's already complete. It already actually had the correct information which is excellent. And then what I'm going to do is just come down to the selector here and let's go ahead and actually select ministry which is just a quick way to do the three experts. And then I'm going to say, hey there, cool. I would like you to go ahead and tell me which is the best country on the planet to live for if you're in your early 30s with a beautiful spring and you love coffee. All right. And then basically this is going to go ahead and debate with all of the Ministry of Experts. And then essentially it's come back, it's done the big debate. We've had a cafe at Alchemist and the verdict is Netherlands specifically Utre which is fascinating. So, if you're from the Netherlands, let me know down below in the comments. I'm beautiful. Just like that, we get our prompt back from Fable 5 that's had all three models that have debated it, which is fantastic. GVT 5.5, GLM 5.2, and Deepseek V4 Pro. So, essentially, Fable 5 is orchestrating. And then we've got these sub agents underneath it that it's calling and we're getting the best out of all of those individual agents. And this fixes very nicely onto level four for our agentic operating system with Fable 5. So, this is essentially the dream, right? The dream is that you go to sleep with your sleep cap on. Don't know who's doing that right now. And Fable 5 works overnight. And the idea is it works on your problems. It thinks about how can we improve things. It spins up sub agency. It does wonderful things. Now we reflect this in our operating system. And this is one of the things that I highly highly recommend that you get. And it's this idea that effectively based on all this information, right? Cloud code activity, anti-gravity, memory files, automations, integration, skills, chat logs, everything on Hermes comes back and dreams for you. So what we're going to do effectively is give it a prompt like this which is I'm going to shoot over to Claude and I'm going to say something like hey there I'd like to go ahead and look at the dreaming functionality inside the operating system and I'd like you to go ahead and improve that in some way find ways how we can make that dream functionality better. How can you look at all the existing data that we have and take it to a completely new level so I get better insights leveraging these models and it's absolutely fascinating the levels of insight. So, Faber 5 did a full reoot of the entire dreaming system, how it works, where it gets the data from, and the suggestions and how it comes back. And what's also really fascinating is the model architecture behind it, which models are doing for dreaming, what other data sources, how does it come together, and just gives you this beautiful overview, this beautiful UI you can look at. You can come down, you can copy this right now if you just want to get this done immediately. You can take it off as you go. It is such a powerful feature. Having a super intelligent AI to review all of your stuff while you're sleeping, working for you, I think is an incredible benefit. And then this takes us very nicely on to level five, which effectively is taking the brain and giving it the ability to follow us around in the Aentic OS. So this is really cool. But wouldn't it be really cool if we could actually talk to the Aentic operating system, right? Have our own. Some people call it Java, some people call it Maverick, whatever your cool name is for it. But I think it would be incredible to have an actual AI system that could follow us around and basically we could ask questions to. So we're gonna give it a prompt like this now because we already have in the Hermes agent here. For example, if I come down to voice, we have the system. Let me go ahead and set this one up. So now I have the full voice intelligence, right? But I come over down here. If I go over to something like the classic and I bring up sonar plasma, I can chat with this, which is really cool. So come down here and begin. Hey Hermes, what day is it today? >> Hello there. Let me check that for you. Just a moment. Okay, so this is a voice interface and it's connected to Hermes. But what I want to do is I kind of want to get a design that looks a little bit like maybe a bit like this that can actually chat to it. So what we're going to do is shoot straight over to Claude code. And so then we get that prompt like this. Hey there, I want you to build for me an interactive voice operating system on top of the Claude Code OS. It should be able to answer any questions about the platform. Just make it interactive and find as many ways as possible to make it as useful as it can be. It should know loads of data. It should be able to click buttons, move around, do various different things. I want it to be as beneficial to me in my operating system as possible. And then literally, we're going to go ahead and send that one off to Fable. Beautiful. So now Fable 5 has completed it. And it looks like we activate it by selecting this thing here at the top. That will turn it off and on. And then if I open this up, we have voice line. So let's click on this. I'm pretty impressed at the actual design it's got. To have this kind of thing at the bottom right is really cool. We click on voice line and we can start a conversation. Hey there. How's it going? Hey there. I'm doing really well, thanks. How about you? >> It's good. It's good. Um, give me a status report, please. >> Sure thing. Here's your status. You've sent over 22,000 user messages so far and I've replied about 39 thou. >> Beautiful. So, you can get the idea now. We can ask it questions. And idea with this is that we can pretty much build out the functionality now. So, from this, I can ask questions about, hey, tell me, you know, let's say for example, I'm looking at a skill. I want you to tell me more about that. Can you help me improve this skill? And the really cool thing is it can actually improve the dashboard itself and code on your desktop because hey, I change it from blue to green and you're doing it live in the actual dashboard. Now, using this incredible operating system is one thing, but there are actually five things that we need to do with Claude Fable 5. They're going to take your entire business and personal life to a new level. And we can learn that by watching this video right
