Opus 4.8 is out and it's an absolute

smash home run. They implemented so many

changes and a lot of these were hidden.

They weren't even in the announcement.

In this video, we're going to go over

every single one of those changes. I'll

tell you exactly what you need to do to

take advantage of all these changes and

then we'll even run some fun tests with

it. If you stick with me until the end,

you are going to be a master of the most

powerful technology that's out there

right now, Claude Opus 4.8. Let's go.

Here we go. We are not a channel where

we sit here for 20 minutes reading blog

posts. Let's quickly go through all the

changes then we'll get straight into the

product. First things you need to know,

it smashes all the benchmarks. It beats

ChatGPT 5.5 and all the other models in

all the benchmarks. Google's not even

close. No one else is even close. This

destroyed all the benchmarks. I actually

believe this is a kind of watered-down

version of Mythos. I'll go into that a

little bit. I'll go in a little bit, but

I actually believe this is Mythos but

kind of a little bit weaker. It's the

same cost. This is mind-blowing and I

think this is a result of all the

compute Elon Musk just gave to Claude,

but it is the same cost as Opus 4.7,

which is this is the first release in

quite a bit of time where the price

didn't go up. For both OpenAI and

Anthropic, all their new releases, the

price ticked up slowly and slowly and

slowly. This is the first one in a while

where the cost did not go up, which

again, just a few weeks ago, Elon sold

to Anthropic tens of billions of dollars

of compute. I think that is a direct

result of that deal, which is really

amazing. Here's a big one and also a big

reason I think Elon's helped out

Anthropic a lot. Their fast mode is

cheaper. A big reason I have been using

ChatGPT 5.5 inside Codex more the last

couple weeks is their fast mode is dirt

cheap. You get way better performance

for not that much more money. Claude,

their fast mode was six times more

expensive, which is untenable. Their

limits were already low, so their fast

mode wasn't worth it. Now their fast

mode is three times cheaper than it was

before, which if we do the advanced

algebra here, comes out to just two

times more expensive than the regular

mode, if my math is correct there. So

their {slash} fast mode is actually

affordable if you're on the $200 plan,

and we'll go into exact recommendations

right after this, so stick around. Beats

Claude GPT 5.5. I thought 5.5 was the

first model ever that beat Opus at

coding, but this one came right back and

beat it. Four times less hallucinations.

So this is a big one, and this is a big

reason why I think this is actually just

Mythos, but watered down a little bit,

is this is one of the things they showed

off with Mythos was the reduction in

hallucinations, about four times

reductions. It's matching Mythos in a

lot of things they advertised before.

And for those who are new to the

channel, kind of new to the AI world,

Mythos is this model that Claude has

been advertising now for a couple

months. They've been advertising it some

sort of doomsday model that's

outrageously good that can hack any

website. They've been teasing us a bit.

It appears we're getting closer and

closer. One big thing to notice also, in

their announcement blog post, this

wasn't in the tweet as well, they expect

to bring Mythos class models to all the

customers in coming weeks, which means

they're doing it. They're actually going

to release Mythos. Again, I think Elon

must saved Anthropic from the dead here.

They were starting to lose in every

single facet because their lack of

compute, and now they're going to

release Mythos. I don't think it's any

coincidence that they're increasing

limits, making prices cheaper, and

releasing super powerful models within

weeks of buying tens of billions of

dollars of compute from Elon Musk. Now

from a new functionality perspective,

here's the two big things, and we're

going to demo this when we get into the

product. Dynamic workflows in Ultra

Code. What are these two things? Why are

they so big and important? Dynamic work

flows is now Claude code's ability to

tackle months of work in just a day.

What does that mean? If you give Opus 48

a very complex task, a big juicy meaty

girthy complex task, it will now spin up

between tens to thousands of sub agents

to tackle that task. Say you were trying

to implement a really big new feature or

one shot a big app. Before, if you gave

it to Opus, it would just have one agent

go there and add some code, take some

code away, add some code, do some

research, add some code. Now it's going

to take literally thousands of those

agents, send them out. They're all going

to be touching different pieces of your

code base, doing research, testing

things out. And simultaneously, these

tens of thousands of agents are going to

be writing code, testing, using the app,

doing regression tests, a whole bunch of

things. It's going to be really really

powerful, and that is now in Opus 48.

Again, this is going to allow you to do

months of work in just one afternoon.

And then you have ultra-code mode, which

is basically giving the keys of the

kingdom to Claude code, to Opus 48, and

saying, "Hey, use dynamic work flows

whenever you want." This is only You're

only using this if you got that $200 a

month plan. So this is Opus 48. I'm

going to go into my exact

recommendations of how to use it in a

second. Then we'll go into the product

and demo it out. But again, absolutely

massive changes here. Let's go into the

recommendations. Number one, switch all

tasks to Opus 48. There's no reason not

to. There's no reason not to go in to

Claude code right now, pull it open, and

choose Opus 48. Now you can choose the

million context if you want. I find the

million context you don't absolutely

have to use it. I find once you start to

fill up that million context window, the

performance actually degrades a good

amount. So, I'm actually an Opus 4 8,

which is the regular context type of

guy. From a effort perspective, I'm

recommending doing a high by default,

and then when you are building out much

bigger things, switching to extra or

max. But, I would by default stay in

high, and then only switch to extra and

max when you have to. Despite the fact

that Papa Elon allowed Anthropic to have

much more compute and capacity, it's

still not as high capacity as ChatGPT.

So, I'm sticking with high for default,

then doing extra and max if necessary.

When it comes to Hermes and open claw, I

wouldn't move it to Opus 4 8 just yet.

This is a big mistake a lot of people

make is they try to force their agents

into using latest version Opus the

moment it comes out. The issue is this

invariably leads to errors, leads to

crashes, and errors and crashes in open

claw and Hermes are not the most fun to

solve. I would wait until the official

releases, which typically come within 24

hours of the release of the model. So,

once it officially releases, then you

switch it over, and you'll have way less

crashes and and way less bad

reliability. As for the slash fast mode

and the new ultra code mode, I'm only

using those if you're on the $200 a

month plan. And even if you're on the

$200 a month plan, I don't know if I'm

using it for every single prompt. Like

ChatGPT Codex, I'm using fast mode for

literally everything cuz they give you

so much capacity. Claude, their limits

still aren't as high as ChatGPT. So, for

me, I actually have extra usage on,

which means once I get past limits, I

just pay through the API. So, I'm

actually going to be using fast and

ultra code for almost everything. But,

for you, if you don't have the extra

capacity or if you're not on $200 a

month plan, then I wouldn't use these

modes. Totally up to you. And here's the

last recommendation before we get into

products and we do some cool demos. You

need to lock the hell in. You need to

lock the hell in. I've been working with

a lot of people lately, watching how

they vibe code, seeing what they do. One

issue I'm seeing is AI is enabling a lot

of people to get wildly distracted. They

will send a prompt to their AI, and then

they will go and doom scroll for an

hour, despite the fact that their AI

finished the task like 50 minutes

earlier. You cannot get distracted. If

you can get into a flow state and lock

the F in, you are going to get so much

more done. I truly believe the number

one indicator of how successful someone

will be in 2026 is their level of focus.

Do not allow this extra power to mean

you can slack off more. Use this extra

power to get more done. So, really work

on your focus, put the phone away, close

social media, close Twitter, close

YouTube, and just lock in, and you'll

get so much more out of this tech. Now,

let's jump into the product and build

some cool things out. I'm using Claude

Code Desktop. You can use the CLI or the

extension to take advantage of Opus 4.8

right now. I'm going to run one of the

world famous Alex Finn benchmarks on

this model. This is a benchmark I've ran

on every single model. Up until now,

Opus 4.7's actually been king with by

far the best scores in all four of these

tests. We're going to run the 3D

first-person shooter test here, see how

it does, see how it compares to the

other models. If you want to run this

benchmark yourself, I'll put the uh

prompt for this down below, so you can

run your own world famous Alex Finn

benchmark. I'm going to hit enter on

this, and I'm going to send it off, and

we're going to see how it does.

Basically, what we're going to have it

do is we're giving it creative freedom.

We're saying build a 3D first-person

shooter using 3.js. Do whatever you

want. Make it as creative as humanly

possible. Add power-ups. Do whatever you

want. We'll see how good Opus does here.

Side note, remote control is active. I

There's actually a setting in Claude

Code not many people know about. You

should be using the setting. It turns

remote control on by default for every

single chat. What this allows you to do

is whenever you spin up a new chat in

Claude, you can actually go on your

phone, go into the code section in the

top left, and as you can see here, that

chat I just started is now on the

screen. Create the stylistic 3D

first-person shooter. So, I can now go

mobile whenever I want with every single

chat I start. So, make sure to turn that

on. A little tip for you there. A little

bonus tip. Go in the settings, turn on

remote control is active. The only thing

I ask for for that tip is you tip me

with a like down below, subscribe if you

learned anything so far, turn on

notifications, and I'm going to do a

full boot camp by an Opus 48 tomorrow in

the Vibe Coding Academy. Make sure to

join that number one AI community on

planet Earth. Link down below. Best

decision you'll ever make in your entire

life. All right, looks like it's done.

It even tested itself, which is sick.

Let's see how this is. Neon Assault.

It's always neon themed. I have no idea

why. First model that makes a non-neon

themed game, I'm going to give it a 10

out of 10. Here we go.

Let's engage. This is nice. This is

nice. These graphics are very, very

nice. Much better I mean, if you're this

is your first time watching my channel,

you might think, "What the hell is this

guy talking about? This sucks. This

isn't Cyberpunk 2027." But, if you

compare this to the default apps that

previous models have built, this is

pretty nice with from the walls to the

ground. These are the enemies. Oh, to

the way the gun shoots, to the way you

can see hit markers on the enemies. I

assume these are Even the power-ups look

nicer.

Wave two. So, they got combos, they got

waves.

This is for sure an upgrade and probably

the best version of this we've seen yet.

Oh, this is an enemy. Okay.

This is probably a step above what 47

gave to me. Probably just a small step.

So, I'm going to give it a 9.1. I'm

going to run the next three benchmarks

probably on a live stream in the next

week. If you want to see that, make sure

to turn on notifications down below for

that. Again, here's a reminder on my

recommendations. You want to be jumping

on this now. When they release new

technology, you have a distinct

advantage if you start using it right

away. Your competition probably isn't

using Opus 4. They're probably not using

the dynamic mode that sends out tens of

thousands of sub agents. They're

probably not using that. So, if you go

and you use this tech and you build out

really, really cool things, you are

going to have a distinct advantage over

the rest of the field. So, you want to

make sure today, carve off some time in

your calendar, go on do not disturb

mode, close out all the doom scrolls you

got, the tickety talks, the Twitters,

all of that, and lock in and use this

and build cool things cuz you have an

advantage right now over everyone else

if you take advantage of all these

different features and functionality

they just released. Let me know what you

want next about Claude. Do you want

tutorials and I build really complex

apps? Do you want deep dives in a

functionality? Do you want more

benchmarking to see if it's the best?

Let me know down in the comments. I'm

super curious what you want. All my

videos are based on your feedback. I

hope this is helpful. See you in the

next video.
