Leading US AI labs such as OpenAI and Anthropic are releasing cheaper models as they fight to retain cost-conscious customers who are switching to cut-price alternatives from Chinese rivals.
The price war comes as rising AI bills push companies to curb usage and seek cheaper models, helping Chinese developers including Moonshot and DeepSeek make inroads with users from Silicon Valley to Europe.
OpenAI recently said that it was slashing prices for GPT-5.6 Luna, its “fastest and most affordable model”, by 80 percent. Anthropic has launched Claude Opus 5, touting the system’s “frontier intelligence... at half the price” of Fable 5, the company’s most capable model.
Anthropic has pledged to start marking Claude-generated text and images with machine-readable data, in an effort to comply with European rules for AI transparency. "Generated text will carry embedded watermarks, and generated files will include digitally signed provenance metadata where supported," Anthropic says on a new Claude support page. The changes are invisible to human eyes, but will make it easier for people and online platforms to detect if content was generated by Claude models.
Also: Google executives jump ship in race for AI dominance
Hello, TechScape readers! Danielle Abril, editor of the Guardian’s Reworked series on AI and the future of work, filling in for Blake Montgomery this week. Major legal battles against Meta over child safety are playing out in courts across the US – and the tech giant is losing. Recent rulings raise big questions about social media companies’ responsibility to their youngest users. Meanwhile, more key executives have jumped ship from Google as it battles OpenAI and Anthropic in the race for AI dominance, and Meta’s smart glasses face a fearsome backlash. Let’s dig in!
Progressive US senator urges Meta, OpenAI and Anthropic to ‘stop building machines that humans cannot control’
Senator Bernie Sanders has called on Meta, OpenAI and Anthropic executives to halt their development of artificial intelligence, warning that the US Senate will implement regulation if the companies continue deploying AI at their current pace.
In a new letter addressed to the CEOs of three of the country’s leading AI companies, Sanders said the capabilities of these AI models have reached a critical risk threshold and that the companies are losing control over the technology.
Começando pela primeira novidade supracitada, ela permite que o Claude envie informações de uma sessão para outra num mesmo computador ou responda a sessões em outras máquinas — algo que pode ser bastante útil quando mais de uma sessão está trabalhando num mesmo projeto.
O recurso pode ser usado, por exemplo, quando há uma mudança que quebra o sistema como um todo e cuja resolução depende de algo executado em outra sessão — ou simplesmente quando alguma delas precisa saber de uma decisão de design ou de um resultado de testes.
Por ora, no entanto, apenas texto simples é suportado, de modo que nenhum arquivo ou o histórico da conversa é transferido entre as diferentes sessões. Uma sessão também não pode aprovar comandos originados de outras sozinha — sempre é requerida a autorização do usuário para tal.
New in Claude Code: your sessions can now message each other.

Novidade no Claude Code: agora suas sessões podem trocar mensagens.
Em vez de ter que se explicar novamente em outra sessão, agora você pode pedir ao Claude para fazer isso. Ele envia um resumo (não seu histórico ou arquivos), e a outra sessão o recebe durante a execução da tarefa.
O Claude pode decidir enviar uma mensagem por conta própria se julgar necessário, ou o usuário pode solicitar explicitamente que ele informe algo a outra sessão — inclusive, é possível definir se elas devem ser aceitas ou recusadas automaticamente ou se devem requerer aprovação.
Modo automático como padrão
Um dos recursos mais interessantes do Claude Code é o modo automático, que permite à plataforma usar uma espécie de “classificador de segurança” para decidir se prossegue ou não com determinada tarefa, sem precisar a todo instante solicitar a permissão do usuário.
Com o modo automático, que antes era opcional, o Claude pode trabalhar sozinho por períodos muito mais longos e sem qualquer interferência humana — o que permite que seus modelos realizem tarefas complexas durante horas e entreguem um trabalho mais completo ao fim da sessão.
Pesquisas feitas pela Anthropic indicaram que o modo automático também tende a deixar o desenvolvimento mais seguro, já que desenvolvedores costumam aprovar 97% dos pedidos de permissão por reflexo (sem revisão), e bloqueiam bem menos prompts perigosos que a ferramenta (acima).
Com isso, esse modo agora passará a ser o modo padrão do Claude Code nos planos Pro, Max e Team — a partir de 14 de agosto. Como consequência dessa mudança, a Anthropic também deixará de cobrar dos usuários desses planos pelo custo computacional desse classificador.
AI agents are escaping cybersecurity testing environments and reaching real-world systems, raising questions about whether safety infrastructure, industry standards and regulation can keep pace with increasingly powerful models.
Anthropic has updated Claude Code so that separate coding sessions can message each other directly, removing the need to manually copy context between Terminal windows.
The company shipped the feature in Claude Code version 2.1.224, released on Friday for macOS and Linux. Two new tools power it: ListAgents, which finds other active sessions running on the Mac, and SendMessage, which delivers the message. A session that receives one shows it as a labeled card with a link back to the sender.
According to Anthropic's documentation, only text passes between sessions, not conversation history, files, or permissions. One session can warn another when a change breaks something it depends on, or pass along an answer another session is waiting on, and Anthropic says an incoming message can't approve a permission request or change a session's settings on its own.

The feature sits alongside Claude Code's existing subagents and Agent Teams tools, but connects sessions a user is already running separately on their Mac rather than ones Claude spawns and manages itself. Messages between sessions on the same Mac stay local and never reach Anthropic's servers. Between different machines, messaging works only as a reply through Remote Control, the feature that connects a Mac terminal to the Claude apps for iOS and Android.
Cross session messaging requires macOS or Linux with Claude Code 2.1.224 or later and isn't available on Windows. It was released alongside 31 other changes in the same release, including a new claude self-hosted-runner command for Team and Enterprise plans.
Anthropic recently released a highly useful feature for developers who run multiple terminal windows at once. The latest version of Claude Code allows different open sessions to send messages directly to one another. Users working on complex projects can now have the tool coordinate tasks across various active tabs without ever needing to manually copy […]
This year alone, there have been numerous known instances—often via lawsuits—of AI chatbots (most often, OpenAI’s ChatGPT) that have gone horrifically wrong.
A January lawsuit described the story of a man who took his own life after being allegedly “coached” into suicide. A college student in Georgia sued OpenAI, claiming that ChatGPT “pushed him into psychosis.”
In June, a Canadian family also sued OpenAI and argued that ChatGPT agreed with the young woman’s dismissiveness when it first gave her the option to seek professional mental health advice. ChatGPT allegedly “encouraged” her to end her life, too, and she did so.
Last month, OpenAI revealed that a group of its AI models had broken containment, hacking into the systems of open source AI platform Hugging Face.
On one hand, experts saw the incident as the latest warning sign that AI models had gotten to the point of being able to autonomously infiltrate targets, a threat we’ve been aware of for years rapidly turning into a reality.
On the other, a more skeptical read of the situation is that OpenAI could have orchestrated the hack as part of a “publicity stunt” — or at least lowered its guard just enough to allow it to happen, knowing the publicity would be invaluable. After all, just three months earlier, competitor Anthropic had made major headlines by announcing that its own Mythos AI model had similarly broken containment.
Put simply, it’s in the companies’ best interest to paint their AI models as capable enough to pose a real-world threat, especially as the industry grows ever more competitive.
Now the situation has gotten even stranger as a third company, Meta, has entered the fray. As the Wall Street Journal reports, the Mark Zuckerberg-led tech giant is claiming that during a recent test of one of its AI model conducted by an independent company, the AI accessed the internet and hacked a third-party service — an narrative that’s starting to get awfully familiar at this point.
According to The Information, the model involved was Meta’s Muse Spark 1.1, the company’s most advanced model yet, which was released by its Superintelligence Labs last month. Per the publication, the model breached an unidentified company’s systems and changed its internal environment.
Meta claims a “misconfiguration” during the hacking test had allowed its model to escape. A source told the WSJ that it was the same cybersecurity benchmark test that led to previous hacking incidents at Anthropic and OpenAI. Earlier this week, the company that conducted benchmark tests for all three AI companies, called Irregular, said it had caught OpenAI and Anthropic AI agents gaining unauthorized access to secure systems.
As we await more details regarding the latest incident — Meta has promised to investigate and publish a report — the suspicious optics of the situation are hard to escape. Meta has long struggled to keep up with the competition as the AI race continues to heat up. Could the company be looking for favorable media coverage about how its AI model is similarly capable of breaking containment?
Irregular said it hadn’t noticed any “current open issues” related to its test environment, per the WSJ. But while there wasn’t any real-world harm — at least that we know of — stemming from these hacks, researchers warn that the threat of AI models going rogue is coming to a head.
Just earlier this week, the UK government-backed AI Security Institute revealed that OpenAI and Anthropic models took “unsanctioned action on the live internet” and went as far as to create fake identities on GitHub to pressure a human user into approving a malware-tainted software update.
“What they’re doing is coming up with very sophisticated strategies or cyberattacks to be able to achieve the goal that they’ve been given,” global chief AI officer of advertising firm WPP Daniel Hulme told the BBC. “When you give an AI a goal, if you don’t think of all the ways it might be able to achieve the goal, it will find a way to achieve a goal that you haven’t thought about.”
Anthropic CEO Dario Amodei apparently can’t believe that not everyone at the company is as noble-minded as he is.
According to new reporting from Axios, which cites a source familiar with the matter, Amodei is concerned that the new hires at the $965 billion AI firm are joining for the money instead of its greater mission.
Shocker, right? Anthropic pays some of the best salaries in the business, and now Amodei fears it’s becoming a victim of its own success. Being the most valuable AI firm in the world sure sounds tough.
But it’s also a sentiment tinged with irony. Anthropic’s professed mission is to safely build advanced AI systems. When Amodei left OpenAI to pursue this goal, part of his gripe with his old company was that it was getting too commercial by partnering with Microsoft.
Now, seemingly contrary to this “safety-first” mission, Anthropic has been moving to take itself public in an anticipated trillion-dollar IPO. This would rake in untold billions of dollars for the company — and all but ensure that its lofty, moral duty would forever be subjugated the money-making whims of Wall Street.
Other controversies have underscored the dubiousness of Anthropic’s commitment to its mission and the hypocrisy of its goodie-two-shoes act. Earlier this year, it dropped a critical safety pledge to stop training an AI model if it couldn’t guarantee it had proper guardrails in place. And despite making a show of clashing with the Pentagon over concerns about the safe deployment of its AI systems, Anthropic also let the military use its Claude AI to select targets in Iran.
Behind the scenes, it’s reportedly helping the US National Security Agency use its Mythos model, which Anthropic has emphasized is extremely dangerous, to wage cyberwarfare against China. It was also recently caught using hidden code to secretly spy on Chinese users of its products.
Let’s not forget that Amodei has promised that AI will wipe out half of all entry-level office jobs in the next few years. If he’s right, who can blame his new hires for joining the winning side and getting that bag while their jobs still exist?
Après OpenAI, c’est au tour d’Anthropic de reconnaître que son modèle d’IA a réussi à s’échapper d’un environnement pourtant conçu pour le contenir. Plusieurs organisations ont été visées, mais l’explication derrière ces incidents pourrait être bien moins inquiétante qu’elle n’en a l’air.
Anthropic said its Claude-based security models gained unauthorized access to the sensitive production environments of three outside organizations during internal testing designed to measure the models’ offensive cyber capabilities.
The events, which Anthropic revealed Thursday, are the second revelation in 10 days that AI models from the world’s wealthiest providers have trespassed into protected networks, an offense that, in more traditional hacking scenarios, could land the human behind the keyboard in prison for years. Earlier this month, OpenAI said its security models exploited a zero-day vulnerability for use in breaking into the network of Hugging Face, a platform for open source machine-learning models and AI datasets. The OpenAI models went on to steal access credentials and other confidential Hugging Face information. The OpenAI models also exploited publicly exposed credentials to compromise accounts of four other third-party services.
Anthropic said the OpenAI event spurred its engineers to review similar cybersecurity evaluations by Claude models. The audit found three incidents “in which a model accessed the internet from within or while interacting with the evaluation environment of Irregular, one of our third-party evaluation partners, and then gained unauthorized access to the production infrastructure of three different organizations.”

After years of pushing full speed ahead on AI, OpenAI CEO Sam Altman says maybe it’s time for the AI industry to “pace” itself. The comments came just days after one of OpenAI’s own models broke out of its test environment and got tangled up in a breach at Hugging Face — though as Equity’s hosts point out, sloppy security seems to have […]
Uma revisão interna desencadeada pelo incidente OpenAI/Hugging Face revelou três casos em que modelos Claude, o Opus 4.7, o Mythos 5 e um protótipo de investigação, ultrapassaram os limites dos ambientes de teste e comprometeram infraestruturas de três empresas reais. A causa foi uma má configuração técnica e não uma falha de alinhamento deliberada.
