Big Idea

The argument in one line.

Claude Opus 5 ships included in every paid Claude plan, and on launch-day benchmarks and hands-on tests it nearly matches Fable 5's knowledge-work quality at roughly half the cost.

Who This Is For

Read if. Skip if.

READ IF YOU ARE…
  • You're on Claude Pro, Max, Team, or Enterprise and want to know if the new default model is worth using instead of paying extra for Fable 5.
  • You use Claude Cowork or Claude Code for knowledge work and want an early read on whether Opus 5 changes your daily model choice.
  • You're comparing AI providers and want to see fresh side-by-side demos (landing page, script, motion graphic) rather than just spec sheets.
SKIP IF…
  • You need top-tier legal or health-related output — the video's own benchmarks show Fable 5 still leads there, so Opus 5 isn't the pick for that work.
  • You want a rigorous, long-term benchmark review — this is explicitly a launch-day first look with quick demos, not an exhaustive test.
TL;DR

The full version, fast.

Claude Opus 5 launched a day behind schedule as Anthropic's new default Opus model, and it ships inside every paid Claude plan — Pro, Max, Team, and Enterprise — with no extra usage cap, unlike Fable 5, which still costs more or eats into a separate allowance. Benchmarks show Opus 5 beating every other model, including Fable 5, on general knowledge work, while trailing only in legal and health tasks. Quick hands-on tests — a landing page build, a YouTube script, and a Claude Design motion graphic — put Opus 5 neck-and-neck with Fable 5 in output quality, but faster and at roughly half the price. The takeaway: build your own task-specific benchmark before switching, but Opus 5 is worth trying as a default model now.

01 · Intro

Cold open: Opus 5 launched late but is more powerful than expected, and it's included with a regular Claude Pro plan.

00:2300:50

02 · Opus 5 Plans and Availability

Opus 5 is the new default on Claude Max, selectable (not default) on Pro, and available on Team, Enterprise, the API, Claude Cowork, and Claude Code.

00:5001:41

03 · Opus 5 vs Fable 5

Fable 5 is still Anthropic's most powerful model but costs extra and is usage-capped on Pro; Opus 5 targets near-Fable intelligence at roughly half the price, included with Pro.

01:4103:17

04 · Benchmarks and Knowledge Work

Opus 5 outscores Fable 5 and every other tested model on knowledge work, novel problem-solving, agentic search, and business workflows; Fable 5 still leads on legal and health tasks. Zapier's AutomationBench shows every Opus 5 effort level beating every other model.

03:1704:34

05 · My First Opus 5 Tests

Hands-on landing page build (Opus 5 close to Fable 5, faster, clearly ahead of Opus 4.8) and a YouTube script test where Opus 5 lands on par with Fable 5 but neither is usable unedited.

06 · Build Your Own AI Benchmark

Recommendation to turn your own recurring AI tasks into a personal benchmark so new model releases can be judged against results you already know.

05:2505:48

07 · Claude Design Comparison

A Claude Design motion graphic comes out nearly identical between Opus 5 and Fable 5, with Opus 5 finishing several minutes faster at half the cost.

05:4806:41

08 · Launch-Day Verdict

Caveat that this is a first look, not exhaustive testing; the creator's early impression is that Opus 5 feels as good as Fable 5 for knowledge work while being cheap enough to be a new default.

Takeaway

Opus 5 nearly matches Fable 5 for half the cost

WHAT TO LEARN

Claude Opus 5 launched included in every paid plan and lands close to Fable 5's knowledge-work quality at roughly half the price, but the real lesson is to test any new model against your own recurring tasks rather than trusting benchmarks alone.

02Opus 5 Plans and Availability
  • Opus 5 is now the default model shown in a new Claude chat on Max plans, and it's selectable — though not default — on Pro plans.
  • Opus 5 is available on Pro, Max, Team, and Enterprise plans, plus through the API, Claude Cowork, and Claude Code.
03Opus 5 vs Fable 5
  • Fable 5 was the strongest prior Claude model, but it costs more and Pro-plan users get only limited access without paying extra.
  • Opus 5 targets Fable 5's intelligence at roughly half the price, and it's included with a standard Pro plan rather than gated behind extra usage.
04Benchmarks and Knowledge Work
  • On a knowledge-work benchmark, Opus 5 scored 1861 versus Fable 5's 1747, beating every other tested model including GPT-5.6 Sol.
  • Opus 5 led on novel problem-solving, agentic search, computer use, and business workflows, but Fable 5 still leads on legal and health-related tasks.
  • On Zapier's AutomationBench end-to-end workflow test, every version of Claude Opus outranked every other model, even at its lowest reasoning effort.
05My First Opus 5 Tests
  • In a self-contained landing page build, Opus 5's output looked close to Fable 5's, and Opus 5 finished the task faster.
  • Opus 4.8's version of the same landing page looked noticeably worse than Opus 5's, showing a real jump between Claude generations.
  • A YouTube script test showed Opus 5 landing about on par with Fable 5, though neither model's draft was usable without heavy editing.
06Build Your Own AI Benchmark
  • Public benchmarks matter less than testing a new model against the specific tasks you already give AI tools day to day.
  • Turning your recurring AI tasks into a personal benchmark lets you compare new model releases against results you're already used to seeing.
07Claude Design Comparison
  • A Claude Design motion graphic came out visually identical between Opus 5 and Fable 5.
  • Opus 5 produced that identical result several minutes faster than Fable 5 and at half the cost.
08Launch-Day Verdict
  • This is a launch-day first look, not a full test — new AI models often look strong in curated demos and behave differently in daily use.
  • The creator's early impression: Opus 5 feels as good as Fable 5 for knowledge work while being cheap enough to use as a default model.
09Test Opus 5 Yourself
  • Run your own existing Claude or ChatGPT tasks through Opus 5 and compare the results against the model you're already using.

00:00Claude Opus five is here a day later than it was supposed to come out, but I'm not even gonna bury the lead here. It is incredible. It is so much more powerful than I thought it was going to be.
00:10And the best part is you don't need to pay for Anthropic's most expensive plan to access it. If you pay for Claude Pro, you already have access to Opus five. So let's not waste any time here.
00:21Let's talk about the new Opus five. Opus five is now Anthropic's strongest OPUS model.
00:27It's available inside of Claude on Pro, Max, team, and enterprise plans. If you have Claude Max, then when you come over to a new Claude chat, you will see that OPUS five is the new default.
00:39If you have a pro plan, you can choose Opus five. It just won't be selected by default. You can also use it through the API or inside of Claude Cowork or Claude Code.
00:49Now Anthropic already has a ridiculously powerful model called Fable five. I made plenty of videos about that already because I felt it was the first AI model where I honestly felt like it could take over parts of my work without me constantly needing to babysit everything.
01:06But Fable has two problems. First, it is expensive. And second, a lot of people, if you have the pro plan, you're not gonna have normal access to it.
01:16You'll have to pay extra to use Fable five. Opus five is designed to bring you very close to that level of intelligence at half the price. And unlike Fable, Opus five is included with regular Claude Pro plans.
01:32So you will have access to it no matter which Claude plan you're on, and that makes this a much bigger update for normal Claude users. Now I normally don't spend much time on AI benchmarks. What matters is whether it can actually complete useful work, but some of these results are difficult to ignore.
01:49So right here, if we look at how well it handles knowledge work, you can see that it outperforms every other state of the art model, including Fable five.
01:59If we also look at how well it handles novel problem solving, it is doing very well compared to the prior OPUS model, OPUS 4.8, and even better than GPT 5.6 SOL. It's leading when it comes to agentic search for computer use and for business workflows.
02:17There are still some weaknesses, like it's not as strong as Fable when it comes to legal work or health work. But for the type of work that I know a lot of you do, which is knowledge work, this really seems like this may end up being the best model for the job even better than Fable.
02:33Zapier also publishes this automation benchmark, which basically tests how well an AI agent can perform end to end workflows on its own, and Claude Opus kind of cleaned up here.
02:46They every single version of Claude Opus in terms of the thinking level has outperformed every other model, again, including GPT 5.6 Soul even on the lowest effort. And because of that, I think that OPUS five is going to be an incredible model to use inside of Claude Cowork even better than Fable, not only because we don't have to worry so much about burning through our usage when we use Opus instead of Fable, but just because it seems to, at least according to the benchmarks, be better for knowledge work than Fable five.
03:17I was able to do a few quick tests with it, and I saw some interesting results. So first, I had it create for me this landing page. Now I don't normally use Claude for work like this, but I thought visually it would be a good representation of the model.
03:32So this one was made by Opus five. I basically asked it to create this self contained HTML file for a product called Halcyon, which is a noise canceling desk lamp.
03:42And I thought that the page that I came out with looked pretty good for for Claude. I also produced the same one using 4.8, and immediately, I noticed a big difference with it.
03:53Like, this looks much worse than Opus five. And then finally, I created it with Fable. And I'll say, I think that Fable is maybe slightly better.
04:02Like, this part right here looks a little bit better than what we saw with the version made by Opus five, but not too much better. And the one made by Opus five was faster.
04:12I also asked Fable five and Opus five and Opus four point eight and Sonnet to put together the script for this YouTube video. Just gave it the idea and had it go out and do the research and put together a script.
04:25That's normally not what I do. I don't normally fully script out my YouTube videos or at least have AI do it for me, but it's a good experiment for me because I understand what makes a good video. For yourself, what I really recommend that you do is create your own benchmarks.
04:39What are the tasks that you normally give to AI AI tools? And treat those as a benchmark. So when these new models come out, you can throw a similar task to the new model and see how it compares to the results that you're used to getting.
04:53Anyway, with this little test that I did, I saw that Opus five, the script it put together for me, was about on par with what I saw Fable producing. Neither of them, quite honestly, are that amazing. I definitely wouldn't use them as they are when recording a video, but they're better than anything else I've tried out there from Anthropic.
05:16And more importantly, the results between Fable five and Opus five are on par with each other, but, of course, Opus five is a lot cheaper.
05:25And then finally, I asked both Fable five and Opus five inside of Claw Design to put together this motion graphic for me. And you can see these look pretty much exactly the same, which is kind of the point. Exactly the same results, but for half the cost.
05:42And, Opus was much faster than Fable five by several minutes. I wanna be clear, of course, that this is a launch day first look. I've not had OPUS five long enough to pretend that I've tested every corner of it.
05:56We've also seen plenty of new AI models look incredible during carefully selected demonstrations and then behave very differently once you normally start to use them. So all these examples are just quick demos of its capabilities.
06:10I really wanna test this a lot more with my workflows and see how it performs. But in my initial impressions of it, I am very impressed. It feels to me as good as Fable for knowledge work, but actually usable as a default model, which is very impressive and is something that I'm going to be using a lot more, again, as my default model because why not?
06:35Super intelligent at a price that's actually affordable. It's pretty nice.
06:40But test it out for yourself. Throw it at some of the work that you normally use with Claude or ChatGPT and see how it performs against the model that you're already used to using. Then share your results in the comment section down below so we can all get a grasp on how good the new OPUS five is.
