Remember when a calculator doing fractions felt like magic? My niece handed me one of those TI graphing calculators back in the early 90s and I thought, well, that's about as smart as a device needs to get. We've come a long way since then.

Anthropic's Opus 5 model just scored a perfect 42 out of 42 on the 2026 Math Olympiad tasks. That kind of result makes you sit up straight. According to Geeky Gadgets, the model is delivering state-of-the-art reasoning performance at half the cost of its bigger sibling, Claude Fable 5. Half the cost. That's a big deal.

I wrote about Opus 5 when it launched earlier this week, and I mentioned it felt like we were approaching a "smartphone moment" for AI, where the price finally makes sense for regular people. A perfect Math Olympiad score at this price point just reinforces that feeling for me.

Now let me be clear about something. Benchmarks are benchmarks. They're tests designed to push a system to its limits under controlled conditions. The Math Olympiad is genuinely hard stuff. These aren't basic algebra problems, they're the kind of puzzles that make talented mathematicians stare at a whiteboard for hours. A model nailing all 42 tells you the reasoning engine is the real deal.

But what I care about, and what I'll keep watching for, is how this translates into everyday use. Can it help my granddaughter Jess brainstorm her college essays without sounding like a robot ate a thesaurus? Can it actually explain a concept clearly when someone is stuck? Can it draft an email that sounds like a human wrote it? Those are the tests that matter to me.

The pricing angle is where this gets really interesting. When capable AI models drop to half their previous cost, it changes who can realistically use them. It's the difference between a tool that sits in an enterprise budget and one that a small business owner, a student, or a curious grandparent might actually pull out of their pocket.

My colleague Marcus could tell you exactly what's happening under the hood to make reasoning this sharp at this price. I just know what I see. A model that's getting smarter while getting cheaper... that's a combination we don't see often enough in tech.

I'll keep watching how Opus 5 performs once more people have spent real time with it. For now, a perfect score on the Math Olympiad is worth your attention.
