Fable 5 is Back! Here's the Best Way to Use It...

Fable 5, the best model ever available to the public that they took down, is back. And along with that, Sonnet 5. And we still have Opus 4.8, which was the best as of 3 days ago. How are normal people supposed to make sense of this? Well, I think they're not, at least not just based off the press releases. That's why in this video, I'm going to break down what the differences are, what you should use, and actually have some prompts here that I want to show you that work particularly well with an extremely powerful new generation model like Fable 5. Not all use cases are created equal. And it's always fun to talk about things that work particularly well with a flagship release. And also the clock is ticking because this thing will not be free forever. It's literally just a few days. So I hope that this video will help you squeeze the most out of these model releases. Plus, we're going to talk about other things that happened in the AI space briefly in this week's episode of AI News You Can Use, a show where I used to cover every single story and now I focus more on the things that I think actually matter, like Fable 5 and Sonnet 5 this week. And as per usual, we always keep it practical. This is about the stuff that you can actually use So let's get into it. And yeah, the headline is simple. Fable 5 is back. Sonnet 5 was just released and is the new default inside of Claude. A lot of people immediately ask, okay, so which one is the smartest? I think a more practical question is, which one should I actually use in what scenario? So let's talk about that. But first, the facts. Fable, if you're not aware, was released a few weeks ago. And then just after a few days, it has been taken down by the US government saying, hey, this is too powerful for the entire world to have access. So Anthropic just made the call to take it down for everyone. Now that those export controls were lifted on June 30th, as of July 1st, everybody has access to this again. Check it out. I go to Claude.ai and there it is, Fable-5. Now you can immediately see that this is only available through July 7th. So if you're watching this video shortly after upload, you're in luck because you can still use this thing for free. One important nuance, it already shows here, this thing is going to shut off when you hit 50% of your weekly usage limits. You can check those out under the profile, Settings, and then here, Usage. Here, it's these weekly limits. They even have an extra Fable counter because they know everybody's going to be all over this. If you're not familiar, Fable 5 eats your credits the fastest. You guys rightfully so corrected me on the last video that it's not exactly 2x of Opus 4.8, which used to be the best model, you know, just as of a few days ago, but it's actually roughly 70% more tokens. We're going to touch on usage and tokens in the end a bit more. But for now, just know that yeah, this is the hungriest model. And you can't even use all of the usage you have in your account, just 50%. Additionally, they added more cybersecurity safeguards on Fable-5. So some prompts that might be harmless might get flagged now, whereas before they would go through. It was already very strict, now it's even tighter. Whenever it hits one of those safeguards, it's gonna fall back to Opus 4.8, their second smartest model. And then on a different note, they also launched Sonnet-5, which is an upgrade from Sonnet 4.8 that we used to have before. If you're not familiar, it's basically the smaller brother of Opus. It's usually faster and way cheaper than Opus, but also not quite as smart. Now, in short, the gap between Opus 4.8 and Sonnet 4.8 just got smaller, way smaller. Opus is still better, but Sonnet is so much faster and more cost efficient. That's why they set it as the default. On many use cases, you won't even notice. As we ran all of our benchmarks, we basically found, hey, on some of them, it's a bit worse than Opus, but it's minimal and it's just a great deal. That's why they set it to the default for free and pro users. Also, it eats up your usage on your account way slower. Like depending on what you're doing, it might be 3-4x, but that's just after one day of usage. But here's the important part. The important part is that Fable is still the GOAT. It's a whole new class of model, and you should totally be using it for complex tasks, for things that need a lot of thinking. That's sort of the conclusion of this video that I'm giving you already. But I also want to give you some things to do and some things to tackle right now before Fable 5 runs out and they switch to token-based usage where you'll literally be paying dollars for every single prompt that you run. As of now, you have a few days to kind of do these things that I'll tell you about. So let's do that. Okay, in no particular order, here are use cases that I found super, super useful. And for most everyday people that are not hardcore devs, this is what I would try now with Fable 5, because again, it's just the best thing out there. First up, the high-level idea here is turning chaos into a plan. So Fable 5, more than any model before, is really, really good at taking in a bunch of chaotic documents, maybe launch documents or business context, and you can ask it to sequence and organize the work. What are the decisions that need to be made?

Here?

In what order should I tackle all of this madness? What am I missing? And what is the first step? It's so good at organizing chaos. It's better than anything I've seen before. This one would be hard to demo in the video. And also, you don't need a precise prompt. Kind of what I just said there roughly is gonna do it. It's more about the context you provide. And no, you don't want to overwhelm it. You don't want to give it hundreds of pages. But if you have a lot of varied stuff and you're trying to make sense of it or trying to plan, if that didn't work perfectly before, well, try that again in Fable. So the demo that I'm going to do here for you is creating something like an AI operating system for your business or personal life. This has been an idea that I was pursuing early last year already, kind of building my own AI Advantage OS and experiments. But people are doing this all over the place. They're building simple little hubs for themselves where different applications and prompts and loops all kind of live in one space. It's a beautiful thing, but many people are kind of overwhelmed by this idea, and rightfully so. It can be kind of a lot at once, like Igor Pogany or AI operating system. What do I even do? Where do I even start? Well, I prepared a prompt here for you. And Fable happens to be the perfect partner for you to do that. So let me open up Claude here and I'll put this prompt into the description below. And really, this prompt is going to have 3 blocks. So let's talk about these for a second. First up, it's context on the task and the task itself. So this is a demo example for you here. But let's say you're a non-technical business owner that wants to turn their company into a simple AI operating system. And then the concrete task is going to be building a 30-day AI productivity plan. But With this context here, it's gonna start designing tooling, not just telling you what to do, which is powerful, especially with Fable 5. Okay, here's really the key ingredient. These are things that I found to work really well and good ones to start with. First of all, we're gonna have the 5 highest value workflows to automate or assist with AI. Fable 5 more than ever is really good at being self-conscious and realizing what it can do because it just trained on all the cybersecurity and development data. It's kind of my explanation for it, but really it's just better than any model before. So try that. The exact first workflow to build this week makes it very specific, gives you like a single win. If you don't like it, by the way, you can always iterate. What input each workflow needs. This is key because oftentimes you'll need some sort of data or something from your side. What output it should produce. I mean, that's workflows one-on-one. Something comes in, something comes out. Make sure to define that here. The human review step. Hey, if you're working with AI, you'll know that most use cases, especially the high leverage ones, have a human in the loop. So let's include that. The likely time safety tweak. This one is at the core of our teaching philosophy at the AI Advantage. We think about how we can save people time and then they can reuse that in other ways, which makes it feel like an investment rather than a chore. A simple tech stack using tools a normal business owner can handle. This just grounds it in the context we gave it in the beginning. And number 8, the first prompt I should paste into Claude to start building this. We don't want an abstract plan. We want like a concrete first step where we can just copy paste something and start making stuff. Nice. And then there's a bit more context. A small coaching and consulting business with 3 people. Sell workshops, one-on-one coaching, a monthly membership. Anyway, there's more details here, including the tools. This is the part that you would customize to yourself. And then I guess you could also customize this first piece. And you could go beyond business. You could make this personal. You could create this for a larger business. I just think this middle stack is really going to be helpful to many people watching this video. So go ahead and try it. So I'm going to run it in here. And you know what, for comparison, we're also gonna run it inside of Sonnet, which is great. Like, I'm not making this video to talk badly about Sonnet. It's a fantastic model. It's just Fable is better than anything else. All right, the results are in. Let's start by reviewing the Sonnet output here. Again, identical prompt. Okay, so let's look at the top 3, especially at the one that it highlighted as the first workflow to build and compare that just in the interest of time. So first of all, a client QA assistant, like a chatbot with context, call to action plan converter. So it takes transcripts and tells you what to do next. Okay, launch planner and email writer, which turns a launch idea into full email sequences. I can tell you this wouldn't be a valuable one, not with a ton of work, that is. Now, the table result. So the ideas are similar-ish, but you can see they're all more specific, which always makes things more actionable. So for example, this one is called Client Q&A Inbox Assistant. Then it tells you that this one is specifically built for emails. And it actually considered the human review piece, which Sonnet ignored. In this case, it would be reading, tweaking, and sending. And then we also have the time saved, which we asked for. Okay, up until now, both pretty good actually. Small differences, but not night and day. But check this out. Recommendation here is completely different. It says build this first, the call converter, because the input already exists. Zoom generates the transcripts for you. There's zero preparation and you can judge the output instantly because you were on the call. And then also the clients feel it. A same-day recap with clear next steps looks premium. And all you need to do on this one is, well, just copy this prompt. And as it says, paste in a transcript and boom, you have a first version of something working. Whereas I think the Sonnet suggestion was also good, but there's way more steps. You have to actually paste in the common questions. So when I told you that Fable is just more practical with these relatively complex tasks, I mean, this is simple enough for a demo here in the video, it just consistently holds true. I mean, the brief was getting a workflow set up immediately. And this just gives you a prompt where you can just get a transcript and boom, you're up and running and there's no extra work. I like that. I know that's subtle, but those subtle differences are the difference between making things happen immediately or not. Now, here's what I would actually do if I ran this. I would do the same prompt for Fable, but I would also attach details on my products and my client. And then if you have a free month or a 12-month goal, also include that. You could put that below this prompt or inside of the context. And then here's a bonus tip. If you go to Cloud Cowork documentation, and then you add in the support article on how to get started with Cloud Cowork that includes some sublinks to how to schedule tasks, or you add any other source or link that basically has context on how a product that you use works, in this case, Cowork, which is really good at intermediate agentic use cases. Well, it will use that information. And this is important. To ground the truth that Fable-5 provides you. It knows a lot, it's very smart, but it's not all-knowing. And oftentimes, you kind of have to nudge it a little bit and give it a chance to do the good work by providing it with the context that matters, which in this case would be the help center of Cowork or maybe documentation on an app that you use. You might assume it has that, but usually it doesn't. AI models are notoriously bad at self-awareness and knowing what exactly they can do. They're good, especially now with Fable, at making sense of what you need and what's doable with these apps and reconciling that. Whether it's this prompt or another, give it grounding information and deep context on you and your business. It's a high-level idea that is going to apply now and 2 years from now. All right, that was very use casey. Here's one more. Use it to plan your application or tool builds. So I know many viewers of this channel have probably built a version of a personalized tool. And Fable is just so good at planning them or improving them. Or building them too. But if I had to rank those three, planning and improving are kind of fighting for spot one, and then building is spot two. Other tools are great at building too. It's just when you make the plan with Fable, gosh, everything just works better, looks cleaner. I guess you could extrapolate that to really planning anything that is a bit more complex. Fable 5 is just the best at that. But there you go. That rounds out our little, you know, Fable use case segment. So in conclusion on these three models, I would say use Fable 5 for the most valuable and the messiest work. Use Sonnet 5 for everyday work. You're gonna get a lot of mileage on your subscription. Or alternatively, use Opus 4.8 if you don't really care about the usage or the money it costs to buy these subscriptions that much. But we're probably going to get Opus 5 soon. And that is kind of the overview of that. All right, that was a bit more time than I planned, but I hope that was valuable to you. And if you want to learn more about context management, there's a link in the description to the AI Advantage Club where I teach courses on context management just like this, but more detailed. It's a $1 trial for 30 days. You can check that out in the description. Let's get back to the video. A few more things that were interesting and hit my radar this week. First of all, Gemini Study Notebooks is an outstanding feature. It's a free adaptive AI tutor inside of the Gemini app, basically quizzes you and adjusts to you. I really love watching the educational space change. And I think this future where eventually everyone will have a personalized tutor is a very compelling one. And this is probably the most mature product that I've seen in that category, especially on a free tier. If you have kids and want to use AI for tutoring, this is the product I'd recommend right now. And we're going to be making a separate video just on this, just because I like this so much. And then there's Gemini Omni Flash, which kind of introduced a new thing that I haven't seen before, which is conversational video editing. It's in developer-only access right now through the API. Eventually, this is surely going to come to the Gemini consumer app. It looks rather gimmicky, to be honest. You kind of talk to it and it does that, but that's not really how you edit videos. Editing is really about thousands of decisions and having a vision for the final product, which I guess you could communicate through voice eventually. Again, I'm intrigued, not convinced yet. I'll keep my eyes on this as it matures. I want to add that we're going to get a new OpenAI model soon. They announced some GPT-4 GPT-5.6 models this week, but only certain organizations in the US have that for now. So we'll see, but that's going to be the new frontier model family upgrading from GPT-5.5 now, which is also amazing, but probably at like Opus 4.8 or Sonnet 5 level. And yeah, those are pretty much all the stories and use cases I wanted to show you this week. Leave me a comment on what you wish was in this video or what we covered on the channel. It's been a while since I asked for ideas. I always love hearing from you guys. And yeah, that's pretty much it. I hope this was helpful. My name is Igor Pogany, and I hope You have a wonderful week.
