Anthropic's new models exposed: Claude Fable 5.5 and a new Opus codenamed Obsidian 3

How long has it even been since Opus 5.5 was released, and there are already new models—and two of them???

Right now, these new models have quietly entered early testing, and some of the actual test result images posted by netizens are pretty outrageous.

This latest leak, once again, came out of X and the Discord community.

At first, someone noticed that an entry called claude-fable-5-5 briefly appeared in Azure's model catalog. Although it was quickly deleted, screenshots were already everywhere.

Then came a flood of all kinds of actual test screenshots.

The most classic one, naturally, is our pelican on a bicycle.

Although the previous model's results were already very good, seeing Fable 5.5's output still makes you go weak at the knees.

Too outrageous.

The texture of this image, the lighting and shadow details—if you hadn't told me, I'd have thought it was generated by Image 2.5.

Zoom in on the details and it's even scarier.

Would you believe it??? The pelican even has a fish in its beak.

On the beach, there are tracks left by bicycle wheels, and the bicycle wheels even have lighting and shadows??

Are you rendering Minecraft here?

But I have to say, I think the pelican-on-a-bicycle test is really pointless now—it's been trained on too much.

But this one is still okay. To be honest, I didn't see much to it; it's about the same as the previous model.

(ps: this is the just-released, not-yet-dumbed-down version)

But comparing them, you can still tell that Fable 5.5 really does have a lot more detail than Opus 5.5—that's probably the strength of a well-rounded model.

That's about it. The news just came out not long ago, so we'll have to keep waiting for more actual test images.

But just as everyone was still marveling at Fable 5.5, another bombshell arrived.

A new Opus model is also on the way.

This is a bit much.

A developer found a model codenamed Obsidian 3 on a benchmark platform, scoring slightly higher than the current Opus 5.5.

First Google releases a new model every two weeks, and the old man finally makes it back to the throne—then Anthropic is ready to strike the moment it pokes its head out.

Just a few days ago, Anthropic officially publicly submitted an S-1 prospectus to the U.S. SEC, initiating the IPO process.

And the scale is quite staggering.

The valuation being discussed in the market has already reached $1.5 trillion to $2 trillion, and it is expected to surpass Mom's SpaceX to become one of the largest IPOs in history.

On the eve of going public, showing the market that you have the most cutting-edge technology and the fastest product iteration speed is the most direct and effective flex.

But really, to be honest, Anthropic's prospectus doesn't need to waste words on all this stuff.

Just put the model release plan log on it, and OK, why bother explaining profit margins (bushi).

So many netizens speculate that the two new models Anthropic just exposed will probably be dropped around the IPO as a bombshell.

However, some well-informed people say directly that everyone doesn't need to wait that long—

at the fastest, one or two weeks.
