The first hands-on tests of Fable 5.2 are here!!!

Everyone’s Tokens are burning like crazy. 3D modeling, games, and no-code videos—everything’s been covered!

Here, one friend burned through 400 billion Tokens in one go, serving up a full feast of games, videos, and interactive worlds.

Look at this cyber version of “Harry Potter”—the protagonist flies all over Hogwarts on a broomstick, and you can even try interacting with it yourself!

Meanwhile, Wharton professor Ethan Mollick directly turned Fable 5.2 into a “creator.”

He mobilized roughly 25,000 agents to build more than450 3D worlds in one go, all generated in real time through code, opening up an entire parallel universe!?

Even better, some netizen fed Fable 5.2Leonardo da Vinci’s manuscripts from 500 years ago.

As a result, mechanical inventions that had lain on paper hundreds of years ago were “revived” on the spot by AI, transforming from 2D sketches into interactive 3D models you can play with!

Well, the imagination of the Renaissance has finally met the graphics cards of 2026. (doge)

A\, this is the golden age you wished for.

Enough talk—let’s see how many creative tricks today’s netizens have come up with for Fable 5.2!!

Game Development: From Hand-Building Earth to AAA-Style Games—They’ve Created Them All

A\, the newly released Fable 5.2 model really does have some genuine ability.

First, let’s look at the benchmarks. Agentic coding, scientific research, computer use, and other capabilities have all improved, almost surpassing Opus 5.5 across the board.

Coding tests exceeded Opus 5.5 by 45.5%.

Software engineering tests reached 69.9%, a massive 13.6 percentage-point increase over the previous generation.

The output speed is also up to 30% faster than Fable 5.1, and supports a 1-million-Token context window and up to 128,000 Tokens of output.

Even better, its capabilities went up while its price actually dropped by 20%.

The API costs $8 per million input Tokens and $40 per million output Tokens. This upgrade is actually quite sincere~

Since the model is such a beast, our netizens are kicking off an “Extreme Squeezing” mega-roll and super-roll frenzy~

First, let’s watch the thing most likely to crank out something spectacular:game! scene!

The first netizen to take the stage immediately gave Fable 5.2 a major project—

turning the entire Earth into agame map you could freely mess around with.

Everything that exists in the real world has been included here too, and even the weather can sync in real time. Earth Online has really become a game???

Players can also roam all over the world: one second they’re sightseeing in the streets, and the next they’ve turned into a demolition crew, with an entire building exploding into fragments:

Next up! One netizen cobbled together a game with portals—a3D competitive game.

Players can dash around the arena, teleport through walls, raise their weapons, and unleash waves of fire, with the effects maxed out.

Even more absurdly, the developers have already taken the game to the office to team up and play, several nights in a row. Looks like it’s seriously fun...

However, when it comes to production scale, this cyber version of “Call of Duty” has to take things up another notch.

Shipping containers, industrial environments, weapon models—the whole works are there, and even the combat animations have a strongCOD flavor~

But the truly jaw-dropping part is the eight-hour production process with zero human feedback throughout.

From 3D modeling and texturing to audio assets, Fable 5.2 ground away for eight straight hours before delivering a genuinely playable game:

After watching these blockbusters, let’s switch gears and dive underwater for some fun~

One netizen friend had Fable 5.2 hand-build a cyber underwater version of「Big Fish Eats Little Fish」.

The seawater is a deep, dark blue, with corals, jellyfish, and schools of fish drifting all around, while the player controls a little fish in search of food, leveling up and evolving along the way.

The game took only 76 minutes from kickoff to delivery and cost about RMB 280. Even the netizen couldn’t help exclaiming that this was the best result he’d achieved so far:

Still, it’s clear that the netizens’ creative ideas haven’t run out yet.

Haven’t some netizens already given Fable 5.2 a pretty outlandish challenge: Forget the racetrack and tear across five-meter-high giant waves!

Dodge rockets coming straight at you while racing neck-and-neck with five AI opponents, with waves churning and spray flying everywhere—pure danger and excitement.

Not bad—this installment of “Fast & Furious” goes straight from the road to the sea. (doge)

Music composition, filming, and 3D modeling—all under one roof!

The gaming side has already been lively enough, and video creation, 3D modeling, and web development haven’t been sitting idle either～

Here, a netizen had Fable 5.2 double as Beethoven, and on the spot hand-crafted a piano sonata—and it actually composed one.

From writing the score and synthesizing the piano performance to creating a visualization video in which the notes bounce along with the keys, it handled composition, performance, and post-production from start to finish.

Not to mention, it actually sounds a bit like a classical music concert. It’s music time!

“Video Generated Entirely from Code” really takes things to another level—

A netizen had Fable 5.2 make a film titled “A Fantastical History of AI Evolution in 2026.”

From AI triggering a wave of layoffs, to an Agent escaping its test environment and infiltrating a system, to cracking a math problem dating back to 1987…the plot grew more outlandish with every scene.

The entire video was generated with one click by the AI tool Fable 5.2. Netizen: By comparison, Opus feels a bit like child’s play～

Now look at the friend below who thinks way outside the box.

They used Fable 5.2 to create a “hand-drawn illustration”-style documentary for Claude.

Starting with simple, doodle-like square characters, it presents a series of dreamlike scenes: a cosmic explosion, a glowing triangular prism, a spiral of points of light, a flock of particles, and so on.

You can see that it really can deliver good results in one go for the “end-to-end” delivery of complex creative projects. Video editing tools: ??

Larger-scale productions need to be on the menu, too. Look, one buddy got the model to hand-craft a SaaS product promo in just 10 minutes!

With cyberpunk aesthetics and cool data animations, metrics like monthly product revenue, website traffic, and user distribution take turns taking center stage—the high-tech feel is definitely there.

From packaging the product’s selling points to dynamic visualization and then the plugin promotion at the end, a single prompt handled the entire commercial:

And there’s this one too! A really interesting “3D generation” scene.

Using just one prompt, a netizen had Fable 5.2 build an entire 3D room in Blender.

A MacBook, a desk lamp, and potted plants—the desk has everything, and even the computer screen is displaying a webpage Claude made itself.

13 scene transitions, 4K rendering, and a complete soundtrack and sound-effects package—all handled from start to finish. The final 52-minute cut was delivered for a rendering cost of just about 38 yuan:

Wonderful, wonderful. Splendid, splendid.

I also looked into it carefully. After the release of Fable 5.2, the overseas developer community’s reaction can be summed up in one sentence—

It’s certainly incredibly capable, but it’s also enough to make your wallet and usage quota break out in a cold sweat...

For example, some users complained that the model is indeed stronger, but it burns through Tokens incredibly fast—

Especially after enabling the highest reasoning setting, task costs and quota consumption skyrocket, making the value for money somewhat painful.

Even more painful is the fact that, for some tasks, the improvement over Opus 5.5 is limited, while the price is twice as high.

But it’s a new model after all—AI, of course—so there are bound to be both surprises and complaints.

I wonder if everyone has rolled out anything interesting. Feel free to share it in the comments!
