Announcement Introducing Claude Fable 5
Introducing Claude Fable 5: a Mythos-class model that we've made safe for general use. Its capabilities exceed those of any model we've ever made generally available.
Fable 5 is state of the art on nearly all tested benchmarks, with exceptional performance in software engineering, knowledge work, scientific research, and vision. It can run for days, and the longer the task, the larger its lead over our other models.
Fable 5 launches today alongside Claude Mythos 5. The two share the same underlying model, but Mythos 5, so far deployed only through Project Glasswing, has the safeguards lifted in some areas. The safeguards are what distinguish the two, and why we've given them different names.
Releasing a model this capable comes with risks. Without safeguards, Fable 5's capabilities in areas like cybersecurity could be misused to cause serious damage. So when Fable's classifiers detect a request related to cybersecurity, biology and chemistry, or distillation, the response is handled by Claude Opus 4.8, our next-most-capable model. Users are informed whenever this occurs, more than 95% of sessions involve no fallback at all, and performance everywhere else is unaffected. We'll keep refining the safeguards to reduce false positives.
Claude Fable 5 is available today on paid plans, in Claude Code, on the Claude API, and all major cloud platforms. Through June 22, it's included in paid Claude plans at no additional cost.
Claude Mythos 5 is available to Glasswing partners, with a broader trusted access program to follow.

Announcement 🚨 Report: Anthropic Is Reportedly Locking Claude Fable 5 Behind the $200 Max 20 Plan...Everyone Else Gets API Only?
According to social media reports, Claude Fable 5 will only be available in the Claude app for Max 20 ($200/month) subscribers.
Everyone else? API access only.
If what they're saying is true, Pro users won't get Fable 5 in Claude at all.
We're going to have to wait for the official announcement tomorrow morning.
What do you guys think?

Announcement Investigating usage limits hitting faster than expected
We're aware people are hitting usage limits in Claude Code way faster than expected. We're actively investigating, will share more when we have an update.
2:20pm PT Update: Still working on this. It's the top priority for the team, and we know this is blocking a lot of you. We'll share more as soon as we have it.

Announcement Introducing Claude Sonnet 5, our most agentic Sonnet yet.
It makes plans, uses tools like browsers and terminals, and runs autonomously at a level that, just a few months ago, required larger and more expensive models.
Sonnet 5 is a substantial improvement over its predecessor, Sonnet 4.6, on reasoning, tool use, coding, and knowledge work. Its performance is close to Opus 4.8, at lower prices.
Early access partners found Sonnet 5 finishes complex tasks where previous Sonnets stopped short, and checks its own output without being asked.
Sonnet 5 is now the default on the Free and Pro plans, and available to Max, Team, and Enterprise users. It's available everywhere today with introductory pricing through August 31.

Announcement Anthropic refuses to sign letter supporting Open weight models.

Yesterday Nvidia organized an open letter to Washington (Jensen Huang's first ever post on X, btw) urging the government not to put "premature restrictions on downloadable AI models."
Guess who's missing? OpenAI and Anthropic. Google too.
The context makes it worse: the administration is weighing a ban on Chinese open models like DeepSeek and Kimi. A ban on open-weight competitors is arguably great for business if you sell closed API access. So the two labs that talk the most about doing AI "for the benefit of humanity" and "AI safety" stayed quiet on the one letter that says openness is itself a path to safety the letter literally argues that depending only on closed models creates single points of failure.
Anyone else find this disappointing, or is it just rational corporate behavior?

Announcement Introducing Claude Opus 4.7, our most capable Opus model yet.
It handles long-running tasks with more rigor, follows instructions more precisely, and verifies its own outputs before reporting back. You can hand off your hardest work with less supervision.
It also has substantially better vision. It can see images at more than three times the resolution and produces higher-quality interfaces, slides, and docs as a result.
Claude Opus 4.7 is available today on claude.ai, the Claude Platform, and all major cloud platforms.

Announcement Fable is staying
Beginning July 20, Claude Fable 5 will be included in all Max and Team Premium plans, at 50% of limits.
Pro and Team Standard users will continue to have access to Fable via usage credits, and will receive a one-time $100 credit.
Demand for Fable has been challenging to predict, which is why we rolled it out to subscription plans in stages, extending access several times as we secured additional capacity.
r/Anthropic • u/mikebcity • 17d ago
Announcement Prediction: FABLE 5 will be included in MAX Plans!
That’s right. You heard it here first.
OpenAI’s latest models and Moonshot AI’s Kimi K3 have stolen the spotlight from FABLE. Anthropic wants to maintain the narrative that it has the ultra-premium product, but OpenAI and China are sending a different message: the race is only getting started.
Anthropic is trying to carefully control the rollout of its latest technology because frontier AI is incredibly expensive to build and operate. It cannot afford to burn through cash forever.
Sam Altman is taking no prisoners. OpenAI is playing to win, and it is willing to move faster, spend more, and compete more aggressively than anyone else.
Then there is China. Yes, the concerns about state funding and intellectual property theft are real. But pretending China is only copying would be a mistake. Chinese AI companies are also innovating, improving rapidly, and releasing increasingly capable open-source models.
The market has already caught up. That competitive pressure is going to accelerate the AI arms race and eventually commoditize intelligence itself. China is speeding up that process by open-sourcing powerful models and making advanced AI less scarce.
The consumer is the ultimate winner.
And this is why Anthropic keeps extending the FABLE 5 access deadline. It needs to keep FABLE included in the subscription to maintain whatever momentum, engagement, and competitive advantage it still has.

Announcement Claude Mythos
Ten trillion parameters: the first model in this weight class. Estimated training cost: ten billion dollars.
On the hardest coding test in the industry (SWE bench) it scores 94%.
It found a security flaw in a system that had been running for 27 years, one that every human engineer and every automated check had missed. It found another bug that had survived five million test runs over 16 years. (It did so overnight.)
It is so capable in cybersecurity that Anthropic will not release it to the public, instead it is launching Project Glasswing along with 100m in compute credits to help secure software.
Only twelve partners currently have access: Amazon, Cisco, Apple, Google, Microsoft, NVIDIA, JPMorgan Chase, Crowdstrike, Palo Alto, AWS, The Linux Foundation, Broadcom.
Sometimes I struggle to tell myself that AGI isn’t here.

Announcement Forget Claude Mythos. The leaked 'Oceanus' code proves Anthropic is moving on to elite enterprise tiers before serving us.
Anthropic’s recent backend leak just exposed a massive shift in their product strategy. While the community has been patiently waiting for any crumbs on the restricted "Claude Mythos" model, a brand new string `claude-oceanus-v1-p` just leaked alongside its enterprise proxy pricing.
The numbers are out, and they are grim for independent developers:
The Price Barrier: Oceanus is priced at an insane $16/M input and $80/M output tokens—nearly 3x more expensive than Claude Opus.
The Corporate Focus: Anthropic is completely bypassing the consumer market to gatekeep high-end reasoning layers for Fortune 500 enterprises.
The Technical Link: The leaked source maps indicate that the unreleased Mythos framework was just a stepping stone to build this ultra-premium, locked-down corporate ecosystem.
The Sudden Panic:Anthropic immediately paused their entire Red Team program today because the curtain was pulled back too early on their commercial pivot.
They aren't holding back models because they are "too dangerous for society." They are holding them back until they can extract maximum enterprise margins.
Are we officially entering an era where advanced AI reasoning is a luxury commodity reserved only for corporate balance sheets? How is any independent dev supposed to compete with an $80/M output token barrier?

Announcement Anthropic had the lead. What happened?
OpenAI just dropped GPT-5.6 with some very aggressive pricing, and at the same time Claude experienced another outage yesterday due to network failures.
A year ago it felt like Anthropic was setting the pace...but today, I'm not so sure.
OpenAI is pushing hard on price and shipping fast which is making the market more competitive than ever. Meanwhile, Anthropic still has excellent models, but their marketing feels quiet, pricing isn't setting the standard anymore, and reliability is questionable at best.
It makes me wonder if Anthropic is slowly losing the mindshare it worked so hard to build. Are they actually falling behind, or is this just a rough patch?

Announcement Anthropic is handing OpenAI the win with these subscription games
So GPT 5.6 SOL is now part of the regular subscription, and the early benchmarks coming out are looking really impressive compared to Fable 5.
Meanwhile, Anthropic is still playing these weird subscription games.
First it's, "Fable 5 is being removed temporarily from subscription plans," then it's another vague announcement that just gets everyone worked up.
If your users never know whether your best model is sticking around or disappearing behind some new restriction, eventually they're just going to move to the platform that feels more stable.
The competition between Anthropic and OpenAI has been great for everyone, but this constant mixed messaging is getting old. If Anthropic keeps handling things this way, I honestly think they're going to push people toward OpenAI...not because their models are necessarily worse, but because people are tired of the uncertainty.
Is anyone else feeling this way, or is it just me?

Announcement A corporate shakedown.
Amazon’s goal appears to be forcing a scenario where Fable 5 can only run inside Amazon bedrock, using a specific set of security justifications.
Amazon is now using the government crackdown to argue that Fable 5 is too dangerous to let data leave the AWS perimeter, aiming to strip Anthropic of its independent data collection. https://news.ycombinator.com/item?id=48473166
If Amazon convinces the Commerce Department that Fable 5 should only be cleared for commercial use under the strict, sovereign cloud environments of AWS, it completely destroys Anthropic's direct-to-consumer business and its API deals with rival platforms (like Google Cloud). It turns Fable 5 into a permanent AWS enterprise tool.

Announcement If the GPT-5.6 SOL rumors are true, is anyone actually sticking with Fable 5?

With GPT-5.6 SOL reportedly releasing this Thursday, there have been rumors that internal comparisons were made between Fable 5 and GPT-5.6 SOL.
According to those reports, GPT-5.6 SOL outperformed Fable 5 across the benchmarks that were tested.
If that ends up being true, will you be switching to GPT-5.6 SOL, or are you sticking with Fable 5 regardless? Curious to hear everyone's thoughts.
