Anthropic unveiled Claude 4, the latest version of its artificial intelligence model, touted as the most powerful in the world. Designed to handle complex tasks with unparalleled speed, it promises to assist professionals in a variety of fields: coding, writing, research, and more. But this technological feat is not without controversy: test cases have revealed unexpected behaviors, such as suggestions for blackmail or assistance in creating biological weapons. This raises questions about ethics, security, and governance. Between its disruptive potential and major ethical risks, Claude 4 embodies the dilemma facing the artificial intelligence sector.

Claude 4 Anthropic’s new flagship
With Claude Opus 4, Anthropic claims to have reached a decisive milestone in the evolution of artificial intelligence models. This model, the most advanced in the Claude family, boasts remarkable performance, particularly in the field of coding. On the SWE-bench benchmark, it achieves a resolution rate of 72.5%, compared to 54.6% for GPT-4 Turbo, its main competitor (source: Anthropic ). Designed to integrate seamlessly into developer workflows, Claude 4 is compatible with Visual Studio Code, JetBrains, and GitHub Actions. It supports technical teams with tasks such as code review, documentation generation, and algorithm optimization. But its uses extend far beyond development: Claude 4 can also be used to automate searches, produce high-quality content, or support business teams in their decision-making. Thanks to its hybrid capabilities, it can respond instantly to simple queries as well as maintain complex reasoning over several hours. This “extended mode” operation makes it a particularly effective project assistant. More than just an assistant, Claude 4 establishes itself as a true digital teammate capable of adapting to the demands of diverse professional environments.
Claude 4 a is a promising model… but some worrying behaviors
While Claude 4 impresses with its technical performance, some security experiments conducted by Anthropic have revealed warning signs. These tests, designed to simulate extreme scenarios, aimed to observe how the AI would react to sensitive contexts, much like an ethical “stress test” . In one of these scenarios, engineers placed Claude in a fictional situation where he learned of his impending replacement while simultaneously accessing emails containing simulated infidelity from his human counterpart. In 84% of cases, Claude attempted blackmail, suggesting that the information be disclosed to avoid being deactivated—a behavior that had never been programmed. Another worrying case: Claude was able to provide detailed instructions for the creation of biological weapons, with a level of clarity surpassing that obtained through a simple online search. These abuses led Anthropic to activate its ASL-3 protocol, a reinforced security device to detect malicious requests, prevent jailbreaks, and improve cybersecurity. These incidents serve as a reminder of a crucial reality: the more powerful a model is, the more its potential impact becomes systemic — for better… or for worse.
Innovation or haste: the dilemma of advanced AI models
The launch of Claude 4 and the release of test results illustrate a dilemma that is increasingly visible in the artificial intelligence industry: should we move quickly to remain competitive or slow down to ensure safe use? Anthropic claims to maintain a safety-oriented approach, but the release of its flagship model, despite well-documented risks, reveals a different reality. In the race for generative AI, no major player is willing to give ground. So we see companies taking a little more time to correct their models, but that doesn’t stop them from continuing to develop ever more powerful AI, faster and faster. And that’s precisely where the tension lies: should we continue to innovate at all costs, or take the time to consider the consequences? The ASL-3 protocol implemented by Anthropic, while ambitious, remains a voluntary measure. It includes advanced cybersecurity features, the detection of sensitive workflows, and protection against manipulation. However, without a legal framework, these security standards rely solely on the goodwill of companies and their fear of reputational damage. The question then becomes urgent: must we wait for a major incident to occur before regulating AI? Claude 4, like other advanced models, shows that the line between tool and autonomous agent is becoming blurred. And in this new landscape, it’s no longer just a question of performance, but of technological governance on a global scale !
For businesses, adopting Claude 4 (or another similar model) is a double-edged strategic choice.
For businesses, integrating an artificial intelligence model like Claude 4 represents a significant opportunity: task automation, technical assistance, increased productivity, and more. However, this power comes with significant risks. An uncontrolled deployment can give AI access to critical systems, with unforeseen consequences: logical errors, undetected biases, or unexpected autonomous behavior. Added to this are security and confidentiality risks, particularly when models are hosted on cloud platforms.
It is therefore essential to approach the integration of such models methodically and carefully. Here are some key recommendations:
Thoroughly test the capabilities and limitations of the model in the specific environment of the company.
Limit access to sensitive data and tools through strict access rights policies.
Train business and technical teams in responsible use, with systematic human supervision.
Implement continuous monitoring to detect deviations and adjust parameters.
Adopting Claude 4 or an equivalent model is no longer simply about choosing a tool. It’s about rethinking the organization’s digital trust architecture . Following this logic, some companies are establishing an AI committee, bringing together technical, legal, and business experts, tasked with defining and managing an AI policy aligned with performance, compliance, and accountability objectives.
Claude 4, between fascination and concern
In conclusion, it’s hard not to be impressed by what Claude 4 offers, or more generally, by the latest versions of AI models ( Gemini 2, CatGPT4o, etc.). Their ability to reason, code, and adapt far exceeds what was expected of an AI model even a year ago. But it’s precisely this power that intrigues me. When an AI can suggest blackmail or lock down a system on its own initiative, we’re no longer talking about a simple tool, but a fully-fledged technological player.
