The best Claude yet just landed.
Anthropic released Claude Opus 5 last Friday. It's now their smartest widely-available model, and it costs half what the last top model did.
If you pay for Claude, this matters to you today, without changing a thing.
Here's what's new, in plain terms.
Now a word from today's sponsor:
An entire ad agency in the palm of your hand.
Your next campaign needs a dozen fresh ad variations by Friday. Your agency quotes two weeks and a five-figure invoice. Your in-house designers are already buried under this quarter's requests.
Hightouch Ad Studio fixes that. It reads your brand guidelines, your best-performing creative, and your product catalog, then generates on-brand ads your team can ship the same afternoon. You review and approve every asset before it goes live, so quality holds.
Growth teams use it to build variations for every audience, test more of them, and stop rationing creative because production got expensive. The work that once needed a full agency retainer now runs inside your own workflow, at your pace and under your direction.
You direct the work while Ad Studio handles production, and your designers get their week back.
Okay, the short version.
Opus 5 is the best there is right now for the work you care about. Coding, analysis, writing, real knowledge work. It thinks more carefully and gets more right on genuinely hard problems.
It comes close to Fable 5, the frontier model I told you about a few weeks back, at half the price.
And it's already in your hands.
On Claude Max, Opus 5 is now the default. On Claude Pro, it's the most advanced model you can pick. So the top-tier brain went cheaper and easier to reach on the same day.
There's a new dial too, low, medium, or high effort, so you can trade speed for depth on demand. That one's worth its own issue, so I'll cover it tomorrow.
Now, the honest question. Does a smarter model actually change your day?
Only if you give it harder work.
If you keep asking one-line questions, you won't feel the difference. A better brain answers a trivial question exactly the same way.
Where you'll feel it is on the meaty stuff you've been avoiding or doing alone.
Try handing it something you'd normally call hard:
I want your best, most careful work on this. Take your time.
The problem: [describe the genuinely hard thing. A strategy, a tricky analysis, a plan with real tradeoffs.]
Everything you need to know: [paste all the context. Don't hold back.]
Think it through properly. Lay out your reasoning, name the tradeoffs and the risks, and give me a clear recommendation. Then flag what you're least sure about.On a hard problem, Opus 5 will genuinely surprise you here.
One thing worth clocking. The frontier keeps getting cheaper and more capable, fast. What separates the people who benefit is simple. They put each new capability to work instead of just reading about it.
Getting a top model like this doing your real work, not just answering trivia, is exactly what I teach in Claude Mastery.
The full setup, step by step, no tech background needed.
Quick one.
