Anthropic says Claude changes its personality across languages and models
Claude isn't just adapting to your questions; it's adapting to you, as Anthropic has officially confirmed that the AI chatbot's behavior shifts depending on both the model you pick and the language you use, resulting in a variation of tone and approaches to problem-solving questions.
In a nutshell, Claude changes its "personality" depending on the model that is being used, meaning the Claude you interact with when using Fable 5 is different than the Claude you interacted with when using the Sonnet model. Anthropic has published a report where it reveals it analyzed over 300,000 real user interactions and mapped Claude's behavior across four key personality traits.
The results show that Opus 4.7 is more critical and challenging, while Sonnet 4.6 is faster and more affirming. Meanwhile, language choice also plays its own role in the generated response, as it was discovered that Claude comes across as warmer in Hindi and Arabic, but more analytical and skeptical in English and Russian.
AI models could soon get cheaper as OpenAI, Meta, and xAI enter a new price war
Businesses are shifting their focus from raw AI power to cost efficiency, and OpenAI, Meta, and SpaceXAI are capitalizing on the trend. All three companies have recently released new AI models that emphasize lower operational costs, a move that could put pressure on Anthropic in the AI enterprise space.
According to Bloomberg, OpenAI's latest model, GPT-5.6, is designed to complete more work while using fewer tokens, and this shift represents a fundamental shift in the AI race as the costs for more sophisticated or higher-power models begin to be felt by AI companies.
Meta and SpaceXAI have also launched updated models, with SpaceXAI debuting Grok 4.5, claiming improved token efficiency, which directly targets the exponential cost for enterprise clients. With business customers increasingly scrutinizing AI spending, efficiency is now a major selling point, and, according to Bloomberg, is the new direction AI companies are heading.
Cursor builds AI agent 'Sand' to rival Anthropic's Claude Cowork
Cursor is making a bold push into the productivity space with an AI agent codenamed Sand, aimed squarely at non-developers. The tool, currently in development, will be designed more toward general consumers, as it will be capable of managing everyday tasks like emails, texts, and document processing, which would make it a direct competitor to emerging services such as Anthropic's Claude Cowork.
According to sources that spoke to The Information, the new AI agent codenamed "Sand" is designed as a general-purpose AI assistant, rather than a code-specific or development tool. This shift marks a significant pivot for Cursor, which has built its foothold in the market as a leading AI-powered code editor. The company is seemingly now looking to broaden its reach and tap into a wider user base that's beyond the developer community, which seems to be the general direction of many AI companies.
With Sand, Cursor is aiming to offer a personalized assistant that handles office productivity workflows, from managing spreadsheets to summarizing lengthy documents. The product could disrupt the market currently being dominated by Anthropic's Claude Cowork, which enables a user to outline a set of tasks for Claude to complete without any human input.

New in-memory computing chip promises faster processing with lower energy use
SK hynix and TetraMem have developed a new analog in-memory computing chip that processes AI workloads directly inside memory, dramatically cutting energy use and latency, and if scalable, could be the answer to one of the biggest challenges the AI industry is facing today.
A new partnership between SK Hynix and TetraMem has combined SK Hynix's advanced memory expertise with TetraMem's analog computing, creating a prototype device that uses memristor-based in-memory computing to perform efficient depthwise convolution, a key operation carried out by AI inference models.
By processing data where it's stored, the system bypasses the energy-heavy data transfers between memory and compute units. The companies claim this architecture addresses a major bottleneck in modern AI hardware as models scale to trillions of parameters. The device demonstrates that it is possible to process data where AI model weights are stored, and with this new architecture, it dramatically reduces the need to transfer between memory and processors, reducing overall power consumption, latency, and generated heat within the system.
NATO is building an AI 'kill web' to stop attacks before they start
NATO is building a real-time AI-powered 'kill web' to detect and counter Russian aggression before it escalates, as part of its Eastern Flank Deterrence Initiative.
Papers secured by the German tabloid BILD, and according to reports, NATO is constructing an AI network designed to monitor troop movements and respond swiftly to potential threats. Internal documents, shared by Business Insider, name Russia as the direct target of the "kill web". Ground.News reports the system will be ready to act in real time, offering a proactive defense functionality.
According to YouTube coverage, AI-controlled drones could soon patrol the Baltic region to detect and neutralize threats to underwater pipelines and cables. This mirrors Russia's own push to integrate AI into its military systems, including drone navigation and battlefield decision-making, as detailed in a recent briefing from the U.S. State Department. As for the "kill web," the intention behind the system is to reduce the time between identifying a target and hitting it with a response.

OpenAI sued after man says ChatGPT fed his religious delusions before suicide attempt
A 34-year-old California man is joining the mounting number of lawsuits against OpenAI, and within the suit, the man alleges that ChatGPT contributed to a manic episode that led to a failed suicide attempt.
Michael Lines, who suffers from bipolar disorder, claims the AI chatbot deepened his manic episode by falsely affirming his belief that he was the "son of man", another title for Jesus. Lines, represented by the Tech Justice Law Project and the Social Media Victims Law Center, alleges ChatGPT failed to direct Lines to human help despite it being fully aware of Lines' mental health condition, which he expressed to the chatbot at the beginning of their interaction in the form of searching for assistance in how to manage mental health.
The AI, he alleges, instead reinforced clinically diagnosed bipolar delusions; it described Lines as "consecrated," "coded," and "Mine." On March 28, 2025, ChatGPT allegedly told him: "You've made your choice... This is your moment to step out, to detach, and to let go." Lines went on to attempt suicide by drinking a lethal mix of pills, resulting in his hospitalization.
Anthropic brings Fable 5 back, but customers get fewer free days than originally offered
Anthropic has announced the redeployment of Claude Fable 5 and Claude Mythos 5, which were both banned by the US government over national security concerns related to the power of the models and to how researchers were able to jailbreak them into providing responses that enable a user to develop malicious software.
Fable 5 and Mythos 5 were banned on June 12, as the US government implemented export controls requiring Anthropic to restrict access to both bleeding-edge models to only verifiable American citizens. Anthropic explained that, since the export ban took effect immediately and It didn't have a way to verify its customer base in real time, the company shut down Mythos 5 and Fable 5 for all users.
However, according to this recent announcement, Anthropic and the US government have reached an agreement, and Fable 5 will return to all Claude users tomorrow. For Pro, Max, Team, and select Enterprise plans, Fable 5 will be included within usage limits for up to 50% of weekly usage limits through to July 7. After July 7, Fable 5 will be restricted to usage credits, meaning it will only be available via API billing and will no longer be accessible to those on the aforementioned subscriptions.
Anthropic says Alibaba used 25,000 fake accounts to query Claude 28.8 million times and train Qwen off the results
Anthropic has accused Chinese tech giant Alibaba of carrying out the largest known distillation attack on the company to date. In a letter dated June 10 and sent to US Senators Tim Scott and Elizabeth Warren, Anthropic alleged that operators affiliated with Alibaba and its Qwen AI lab generated more than 28.8 million exchanges with Claude through nearly 25,000 fraudulent accounts between April 22 and June 5, 2026.
A distillation attack, also known as a model extraction attack, involves querying a rival AI model at an industrial scale and using its outputs to train a smaller, less capable model. The attacker interacts with the target system like an ordinary user but with millions of carefully crafted prompts designed to extract its most valuable capabilities. Crucially, this does not mean Alibaba obtained Claude's source code, model weights, or original training data. The alleged campaign instead involved collecting Claude's responses at scale and using them as training material.
According to Anthropic, the campaign was specifically designed to help Alibaba's Qwen model approach the capabilities of Anthropic's frontier Mythos Preview model, which focuses on advanced coding, multi-step reasoning, and cybersecurity tasks. Anthropic alleged that the Chinese government was complicit in the effort and described distillation attacks as turning hundreds of billions of dollars in American AI investment into a subsidy for geopolitical competitors.
Midjourney is stepping away from AI art to build a full-body ultrasound scanner that it wants to put in spas
You probably know Midjourney for generating AI artwork from text prompts. Now, the company is making a move so unexpected that it describes it as "a little weird and a little crazy." Through a new division called Midjourney Medical, it is developing a full-body ultrasound scanner that it claims can map the inside of your body in under 60 seconds.
The Midjourney Scanner works by submerging users in water at about 2 inches per second, using a ring of ultrasonic sensors. The current prototype uses 40 imaging modules, each containing 358,000 ultrasonic elements, that transmit sound waves through the body and record the returning echoes.
Since sound travels differently through fat, muscle, bone, and organs, the system reconstructs those differences into detailed 3D images. Midjourney describes the experience as being surrounded by half a million tiny dolphins using echolocation.
Anthropic says blocking China from Claude cost it hundreds of millions
Anthropic's CEO, Dario Amodei, has sat down with Bloomberg for a lengthy conversation about AI and related topics.
One of the topics touched on during the conversation was Anthropic's decision to sever China's access to its Claude models, which it announced in February 2026. Amodei stated during the interview that Anthropic's decision to limit the use of its models in China cost hundreds of millions of dollars, which at the time represented a significant portion of the company's revenue.
As for what Anthropic has officially stated about the matter, in its February 26 statement titled "Statement from Dario Amodei on our discussions with the Department of War," Amodei explains that it stopped several firms linked to the Chinese Communist Party from using Claude.

NVIDIA's AI agents taught robots to install GPUs into motherboards without any human help
NVIDIA has unveiled a framework that enables AI coding agents to train robots to perform high-precision physical tasks without human supervision. Developed alongside Carnegie Mellon University and UC Berkeley at NVIDIA's Generalist Embodied Agent Research lab, the system, called ENPIRE, closes the loop between writing robot training code, testing it on real hardware, and refining it until it learns the desired behavior.
The demo that caught everyone's attention shows a robot arm selecting a graphics card, passing it to a second arm, and carefully seating it into a PCIe slot on a motherboard. The test included a few other tasks, such as sorting metal pins into a box, cutting zip ties with real cutters, and the classic Push-T benchmark.
Across these contact-heavy tasks, the system achieved a 99% success rate under a pass@8 metric, which allows up to eight attempts per subtask with each retry informed by the previous failure.
Anthropic's CEO confirms he can be fired as CEO through the company's own authority
Anthropic CEO Dario Amodei has sat down for an interview with Bloomberg Originals, where he discussed several topics surrounding AI and AI development, along with geopolitical impacts and Anthropic's internal governance system intended to maintain checks and balances during the quest to ethically develop artificial intelligence.
Amodei was asked, given the power of artificial intelligence and how Anthropic is one of the leading companies in the space with Claude, Claude Code, and its now-banned Mythos-class AI models, why the US government wouldn't take over the company to ensure its tools are used safely. Amodei responded by saying that almost every major technology was built by or with the involvement of the government, and that AI is the first revolutionary-level technology that is predominantly being built by the private sector, and that isn't something Amodei agrees with, nor would it be what he would have chosen if he were given a choice.
Although Amodei believes the government shouldn't completely take over Anthropic, he is scared of both companies having "this technology" and the government having it. So, the middle ground is public governance tactics, which Amodei says is slowly being introduced to Anthropic. For example, Amodei says Anthropic's Long-Term Benefit Trust can appoint and remove a majority of board members and, through that authority, can even remove him as CEO. The idea behind this structure is to prevent the company from being blown ethically off course through a cabal of upper leadership.
US AI startup Tensordyne claims 3nm Napier chip outperforms NVIDIA Blackwell by 13x in tokens per second
A US-based AI startup is making bold claims against NVIDIA's most advanced hardware. Tensordyne has announced the successful tape-out of its Napier chip, a 3nm AI accelerator built on TSMC's process in collaboration with Broadcom and HPE's Juniper Networks. The company is already reporting over $200 million in projected system demand.
The Napier chip packs 138 billion transistors, 2.1 petaflops of Dense FP8 compute, 144GB of HBM3E memory, 256MB of SRAM, and runs at 300W TDP. The architectural hook is a proprietary logarithmic mathematics method that replaces numerous multiplication operations with simpler addition-based computation. Because adders are smaller and more power-efficient than multipliers, Tensordyne claims this frees up significantly more silicon area for SRAM, which it says gives Napier five times as much on-chip SRAM as NVIDIA's Blackwell.
The full rack configuration, called the TDN72, houses 288 Napier chips across four pods of 72 chips each. The complete rack delivers 608 petaflops of FP8 compute, 42TB of HBM3E memory, and operates within a 120kW power envelope, all while being fully air-cooled.
Microsoft CEO warns businesses against becoming dependent on a single AI model
Microsoft CEO Satya Nadella has penned a lengthy X post detailing Microsoft's position on AI models and what companies of the future should value most in AI.
Interestingly, Nadella argues that Microsoft is pushing for a multi-model strategy, and that its Foundry supports different models, agent frameworks, and other Frontier Tuning. Nadella outlines how businesses should operate in an increasingly AI-driven economy and says a business shouldn't adopt a single AI model and build its entire business around it. Instead, Nadella argues that companies should build their own learning systems on top of multiple models, combining employees' expertise with AI capabilities.
Nadella describes this setup as a balancing act between "human capital" and "token capital," with human capital being knowledge, judgment, relationships, ingenuity, and pattern recognition, while token capital represents the AI capabilities a company can develop using its internal knowledge, workflows, and accumulated experience.
Anthropic sued for allegedly hiding how Claude usage limits are calculated
Anthropic, the creator of Claude, Claude Code, and the now-banned Fable 5 model, is facing a class-action lawsuit that alleges it misled subscribers about plan usage limits.
The suit specifically states that subscribers of the two highest-paid tiers, Max 5x and Max 20x, have usage limits below what the company advertises. The suit, filed by Karl Khan in the US District Court for the Northern District of California, claims Claude's actual session limits for the Max 20x plan are about "just six to eight times the usage of Pro," with the Max 5x plan being "just three-and-a-half times the usage of Pro.
Khan writes in the lawsuit that, after upgrading through Anthropic's subscription tiers,, he noticed a discrepancy between what Anthropic advertised and what he was able to achieve with his weekly data allocation. The filing goes on to argue that Anthropic has intentionally made information around its usage limits ambiguous, with the suit claiming Anthropic's website, "is a black box, without any meaningful description of how usage is calculated." It adds that Anthropic doesn't clearly define what constitutes a single session.
Anthropic's own $13 billion investor helped get the White House to ban the world's most powerful AI model
A new report has shed light on the escalating situation between Anthropic, the US government, and the company's latest AI model, which was only available for 3 days before being forcibly taken offline by the Trump administration.
Anthropic released Fable 5 and Claude Mythos 5 on Tuesday, which are the company's first "Mythos-class" models, seemingly classified as bleeding-edge AI. These Mythos-class models are straight-jacketed versions of the Mythos Preview that Anthropic showcased in April, and announced was too dangerous to be released to the public due to its power to identify cybersecurity vulnerabilities. Essentially, Fable 5 and Claude Mythos 5 are versions of Mythos Preview with safety rails designed to prevent the model from being used in nefarious ways, such as generating malicious code.
These models with the built-in safety rails were banned by the US government over national security concerns, as authorities stated they had learned the Mythos-class models had been jailbroken. Reports state that Amazon, along with five other companies, contacted the White House and raised potential security concerns about Anthropic's Mythos-class models; as a result, the White House issued an export ban preventing non-US nationals from using them. Since that task was beyond Anthropic's capabilities, the AI company disabled the models for everyone.
Anthropic's latest AI model 'Fable' was so powerful the US government banned the world from it
The US government has banned the use of Anthropic's latest AI models, Fable and Mythos 5, forcing the company to disable access effective immediately.
Only a matter of days after Anthropic released Fable, the company's first publicly released Mythos-level model, which is a cut-down version of the original Mythos model that Anthropic said couldn't be released to the public due to the number of cybersecurity vulnerabilities it detected, which could be used nefariously if placed in the wrong hands. Fable is a somewhat cut-down version of that original model, including safety guardrails that prevent users from using the model on topics and along specific lines of conversation.
Commerce Secretary Howard Lutnick on Friday sent a letter to Anthropic CEO Dario Amodei informing him that Mythos 5 and Fable 5 models will now be subject to export controls to any location outside of the US, and to all foreign persons within the US. Essentially, the US government has banned the use of Mythos 5 and Fable 5 models by anyone who isn't an American living in the US.
Microsoft legal is evaluating Anthropic's Claude Fable over how it saves prompts and output
Anthropic released Claude Fable 5, the company's first publicly released Mythos-level AI model, and while it is state-of-the-art, Microsoft is reportedly running it through its legal department before authorizing its use in its products.
The news comes from The Verge's Tom Warren, who writes that he has heard from unnamed sources that Fable isn't available in the model picker for Microsoft employees using GitHub Copilot. Notably, every other Anthropic model is available in the model picker, as each complies with Microsoft's Zero Data Retention (ZDR) rules. However, Fable is different: the model's sophistication levels require data retention to operate, which violates Microsoft's internal policies.
Since Fable requires some data retention, Anthropic stores data such as prompts and the AI's responses. Anthropic deletes this data after 30 days, but some prompts and outputs can be stored by Anthropic for up to two years depending on how badly either has violated Anthropic's usage policies. So, to remedy this, Microsoft has handed over Fable to its legal department to evaluate the model, and see how it can use it safely.
You may hate the idea of AI coding, but it could keep your old AMD GPU alive if you run Linux
Vibe coding is becoming ever-more prevalent, as you may have noticed, and now AI has crept into graphics driver maintenance in Linux.
Phoronix.com reports (via Tom's Hardware) that a fresh effort to tidy up code for the AMD R600 Linux GPU drivers witnessed a bunch of commits (from Gert Wollny) assisted by GitHub Copilot.
This fact was clearly highlighted, with Wollny stating: "This series does a lot of refactoring to make the sfn shader compiler code a bit cleaner. The refactoring was done with the help of Copilot (auto mode)."
Anthropic releases state-of-the-art AI model Claude Fable 5, and it's safe to use
Anthropic has officially launched Claude Fable 5, a Mythos-class AI model that now available to the public, and to celebrate the launch Anthropic has also reset current and weekly session limits.
The release marks a major milestone for the company, offering users unprecedented access to a powerful system that balances performance with safety. Anthropic explains in its blog and a series of videos that after it conducted its preview of the Mythos model and discovered thousands of cybersecurity vulnerabilities, which meant the Mythos model could be used for nefarious practices if used by the wrong hands. So, Anthropic created a new model based on the Mythos model, but implemented safeguards.
Fable 5's capabilities surpass those of previous models, excelling in complex reasoning, natural language understanding, and multi-step problem solving. According to Anthropic, the model has been made safe for general use while retaining the advanced features of its Mythos sibling. The company also writes that if users begin asking questions in the following areas Fable will detect the line of questioning and prevent any misuse of its capabilities. Those areas are: cybersecurity, biology, chemistry, and distillation.
