According to the The Wall Street Journal, the export control directive that led to Anthropic cutting off access to Fable 5 and Mythos 5 was triggered in part by cybersecurity research from Amazon and conversations between CEO Andy Jassy and the White House. According to the report, the paper from Amazon claims that, through a series of prompts, it was able to get Fable 5 to serve up information that could be used in cyberattacks. Amazon has yet to respond to a request for comment.

Shortly after Jassy shared the company's findings with the government, it made the call to block its use by foreign nationals. Complicating this issue is that man …

Amazon CEO Andy Jassy may have been the source of security concerns that led Anthropic to cut off worldwide access to two models on Friday.

On Friday evening, the government ordered Anthropic to block access to Fable 5 and Mythos 5 for all foreign nations, both inside and outside the US, due to national security concerns. That order included employees of Anthropic. To meet those demands, the company has completely cut off access to the models for all customers.

In a statement, Anthropic said that while it was complying with the order, the government "did not provide specific details of its national security concern." Instead, it claims that any evidence of potential jailbreak was provided verbally, and that the vulnerabilities discovered were minor and available via other model …

Learn what Claude Code is, how Anthropic’s AI coding agent works, where it excels, its limits, pricing concerns, and who should use it.

The IPO market is back, and it’s not the same companies leading the charge. FAANG had a good run, but a new acronym is taking over: MANGOS — Meta (or Microsoft, depending on who you ask), Anthropic, Nvidia, Google, OpenAI, and SpaceX. Half of that bunch is heading to public markets in the same window, and it’s a stress test for investors, for valuations, and for […]

O Claude Fable 5 é a primeira versão pública da classe Mythos da Anthropic e supera todos os modelos anteriores em praticamente todos os benchmarks testados. Mas chegou ao mercado com salvaguardas tão conservadoras que perguntas básicas de biologia ativam o sistema de segurança.

The partnership will see TCS creating a business unit focused on deploying Anthropic's AI models to its customers.

Anthropic has apologized for stealthily throttling its new AI model, Claude Fable 5, with hidden guardrails that undermine both researchers and rivals using it to develop competing systems. The company says it is reversing course and will be more transparent about when the restrictions kick in, even if that means Fable refuses more queries.

Fable is the first widely available model in Anthropic's Mythos class of AI systems, a group the company has spent months warning are too dangerous for public release. Anthropic says it has addressed some of those risks by launching Fable with safeguards that prevent it from responding to certain "high-r …

OpenAI may soon make its artificial intelligence services cheaper. The Wall Street Journal reported on Wednesday, citing sources

If founders and other business leaders weren't already envious of Dario Amodei, who sits atop one of the world's fastest-growing AI companies, they're going to be seriously envious now.

Anthropic just released Claude Fable 5, calling it the most powerful AI model it has ever made widely available and praising its skills in biology, among others. But the model won't answer basic biology questions - the kind you'd expect a high schooler to handle. Instead, it hands off the query to the former flagship model, Claude Opus 4.8.

It isn't because Fable doesn't know the answers. It's because Anthropic won't let it, by design.

Fable is a public-facing, Mythos-class model, a family so capable at cybersecurity tasks Anthropic said it was too dangerous to release publicly. But while Anthropic has spent much of the extended Mythos rol …

OpenAI has confidentially filed a draft S-1 with the SEC, opening the door to an IPO as Anthropic and other AI firms eye public markets.

Anthropic released Claude Fable, its first Mythos-class AI model, yesterday and it's already causing concerns inside Microsoft. Sources tell me that Microsoft is limiting the use of Claude Fable 5 for employees because of Anthropic's new data retention requirements.

While Microsoft quickly rolled out Claude Fable 5 to its GitHub Copilot and Foundry customers, I'm told the model isn't available in the model picker that Microsoft employees use for internal versions of GitHub Copilot. All other Claude models are still available internally at Microsoft, because they operate under Zero Data Retention (ZDR) rules.

I understand that Microsoft ha …

Cybersecurity researchers are complaining that Anthropic's new model Fable has guardrails that are too strict for any cybersecurity work.

Instead of spending a year raising a formal venture fund, the Sabertooth VC founder used a captive network of LPs to invest in startups like Anthropic, Anduril, and SpaceX.

Anthropic's Claude Fable 5 is going to be a big hit with the web's vibe coders.

If those same AI workloads can be handled by cheaper models without affecting quality, it would mean a massive shift in the economics of AI.

Anthropic is releasing Claude Fable 5, its first Mythos-class model available to the public. The model comes with guardrails that block responses in high-risk areas like cybersecurity and biology.
