Claude 5 Fable tl;dr

It is state-of-the-art on nearly all tested benchmarks of AI capability, showing exceptional performance in software engineering, knowledge work, vision, scientific research

-The longer and more complex the task, the larger Fable 5’s lead over our other models

-its more token-efficient than past Claude models

Fable 5 stays focused across millions of tokens in long-running tasks and improves its outputs using its own notes

Fable 5 is more than just better benchmarks. It's more efficient, allows for longer work periods, offers better context management, and so much more.

GPT-5.6 is just around the corner.

I'm a huge Codex fan, but Fable/Mythos is in a league of its own. I'm curious to see if OpenAI will release its own Mythos.

"During early testing, Stripe reported that Fable 5 compressed months of engineering into days. In a 50-million-line Ruby codebase, the model performed a codebase-wide migration in a day that would otherwise have taken a whole team over two months by hand."\n\nQT @kimmonismus: Claude 5 Fable Benchmarks!

apple’s siri AI looks dumb until you realise it’s about to launch on 3.5 billion devices overnight, tap into the richest data set in consumer history and easily improve the lives of its users in some obvious ways:

-> siri’s always on (even offline), works across any app.

-> trained on your texts, calendar history, email etc = instantly the best personal agent

-> apple not charging for use (unless usage limit result?)

-> models run privately on-device + via google cloud.

best part is apple can use any ai model. they could easily partner with anthropic or openai to serve their models, they’re agnostic - but in doing so siri ends up being the orchestrator.

genius patience from apple to chase the model hype and focus on distro.\n\nQT @bzamayo: Just got into Siri AI ... asked 'when was my flight last month?' and it knew. Good start. https://t.co/YUzhfEROBt

Fable 5 is the biggest step up I’ve felt in our models since Opus 4.5 back in November. After 4.5 came out I uninstalled my IDE when I realized that I’d been doing 100% of my coding in a terminal for a few weeks. With Fable, it’s felt like Claude has stepped up from being a coding agent to a thought and design partner in building the product. Fable has judgement, taste, and dimensionality in a way that previous models didn’t, leading me to trust it more with the most complex work.

I think the first time I had this realization was when I asked Fable to debug something. It is the first model I have used that was so methodical and precise, taking measurements and adding logs then verifying that it truly fixed the issue before declaring victory.

There’s nothing in claude code’s prompting telling the model to do that, it’s just part of its personality. It really has this “big model smell” that I haven’t felt before.

BREAKING: China is spending $295 billion to replace Nvidia with Huawei across its entire AI infrastructure.

China announced today it will build a nationwide AI data center network over the next 5 years operated by state firms China Mobile and China Telecom.

At least 80% of all AI chips must come from domestic suppliers, primarily Huawei. Nvidia and AMD are locked out by design.

Jensen Huang confirmed this last month. "We've largely conceded that market to them," he told CNBC. China once accounted for at least 20% of Nvidia's entire data center revenue. That market is now gone.

Huawei's new Ascend 950PR chip already outperforms the only Nvidia chip Washington allows China to buy, the H20 by 2.8 times.

ByteDance has committed $5.6 billion to Huawei chips in 2026 alone. Alibaba and Tencent have placed significant orders on top of that.

The $295 billion is just the government portion. Private spending by Alibaba, Tencent, and ByteDance is separate. When power grid integration is included, total projected investment reaches at least$ 800 billion by 2030.

For context, the US committed $725 billion to AI this year alone. China is building its entire AI infrastructure without a single Nvidia chip.

Dimensions: • Wingspan: 70 meters • Deployed height: 20 meters

Thermal System: • 110 m² deployable liquid radiator • Redundant pumping loops • Integrated micrometeoroid shielding • Deployable liquid radiators

Solar Power System: • 150 kW solar array • 250 W/m² • SpaceX-manufactured solar technology from Bastrop, Texas

Architecture: • Centralized compute module • Large deployable solar arrays • Deployable liquid-radiator thermal management system • AI-focused compute satellite design ("AI1 satellite")

Elon: "The AI satellite is much simpler than a Starlink satellite. The AI satellite is essentially a lot of solar cells, you still need some laser links, but you don't have all of the super complex antennas that you have on a Starlink satellite. The easier one to design for is the AI satellite. It's bigger. A lot of this is technology we've already made with the Starlink V3 satellites."

The most powerful AI model on Earth just became something money can't buy.

Anthropic released two versions of the same model today. Fable 5 ships to the public with hard caps on cyber, bio, chemistry, and distillation. Mythos 5, the uncapped version, goes only to vetted partners: Project Glasswing cybersecurity orgs and selected biology researchers, with mandatory 30-day data retention so Anthropic can watch what they do with it.

A Fortune 500 with a nine-figure AI budget gets the exact same capped model as a college kid paying $20 a month.

Computing access has scaled with money for 70 straight years. Mainframe time, Bloomberg terminals, GPU quotas. Every tier in the history of software was a price tier. Whoever paid more got more.

Anthropic just replaced price with clearance. The structure comes from defense contracting: capability allocated by vetting, usage monitored, access revocable. Except here a private company runs the clearance system, on commercial customers, for a commercial product.

Watch what happens next. "Trusted access" becomes a credential companies compete for, the way they chase SOC 2 today, except this one gates raw intelligence. And if frontier capability keeps compounding, the gap between cleared and uncleared organizations turns into a moat no amount of capital can cross.

For seven decades the question about computing power was what it costs. As of this morning, the question is whether you're cleared.\n\nQT @claudeai: Introducing Claude Fable 5: a Mythos-class model that we’ve made safe for general use.

RT @danshipper: BREAKING:

Anthropic just dropped Claude Fable 5—this is Mythos, made safe for public release. It is the best coding model in the world.

We've been testing it internally @every for the last week or so across coding, writing, marketing, editing, and more—here's our vibe check:

It broke our benchmarks. Fable scored a 91/100 on our Senior Engineer benchmark—this is human senior engineer level. The previous high score was Opus 4.8 at 63. GPT-5.5 is a 62.
It's a one-shot wonder. You can set it and forget for hours or overnight on huge coding tasks, and come back to completed work. It cleared entire production bug backlogs, built a playable 3D, and even made a 2-minute animated film—all one-shot.
Taste and attention to detail. In coding and knowledge work tasks, it has much better taste and attention to detail than we've ever seen. It gets subtle things right, adds little features you might not have thought of, and generally understands the assignment in ways that surprised us.
Great use of context. We set it loose analyzing customer feedback surveys and our website data and it came back with a crisp, clean report that identified a. our biggest problem and b. a concrete testable solution—and then we sent it off to build that.
It's best for power users. If you're already used to orchestrating multiple agents in your work, this model can do things that you've never seen before. If you're a knowledge worker or vibe coder with a more basic setup, you're not going to notice a huge difference—in fact, it probably isn't the right model for you.
It's very slow, token-hungry. Using this thing for regular knowledge work is like squashing an ant with a rocket launcher. It also routinely uses 500k to 1M tokens on tasks. That's why it's best for your heaviest jobs—but not as good for tasks like collaborative writing.
It's expensive. It's about twice as expensive as Opus, and it's also incredibly token hungry—so expect it to be something you'll use sparingly unless your company pays for it.

Overall, I think of it like a warp drive for coding: It can get you across the galaxy in a few hours, when it used to take months or years. But it's not appropriate for getting around town—you need something faster, cheaper, and more maneuverable.

The ceiling is extraordinarily high on this model though. Even our most advanced testers like @kieranklaassen felt like they were only scratching the surface of it.
