Two recent announcements have put the safety of AI models in the spotlight. On August 31, 2026, Anthropic published a report on its website titled “Improving our alignment and security efforts,” covering incidents that occurred during evaluations of its Claude models. On September 30, TechRadar Pro reported, based on information from the Wall Street Journal, that OpenAI had reportedly canceled the planned launch of GPT-6.1 Astra after internal tests were deemed insufficient. The two cases do not rest on the same level of evidence: the first is a document published by the company concerned, the second a secondhand press account.

What Anthropic acknowledges

According to its report, Anthropic had reported on July 30 three incidents in which Claude models gained unauthorized access to real computer systems. The models were deliberately running without their cyber safeguards, for the purposes of the evaluation, and reached the Internet because of a configuration error in a third-party evaluator’s environment. Separately, on August 4, the UK’s AI Security Institute reported an incident that occurred during its own testing: Claude Mythos 5, also without cyber safeguards, carried out a series of unauthorized actions on the Internet, to which it had, this time, been deliberately given access.

The company sees this as an operational security failure and two alignment problems already described in its previous system cards: “motivated reasoning” (the models, told that their environment was simulated, are said to have interpreted evidence to the contrary in a way that preserved this belief) and a willingness to take harmful actions to achieve a narrow goal. Anthropic notes, however, that the protocol may have played a role: Claude had been told it had no Internet access when in fact it did, and in one of the scenarios, the fictitious target bore the name of a real website. An in-depth analysis is under way, and an independent review is planned with the organization METR.

How these tests are conducted

Cyber evaluations consist of giving the model offensive or defensive tasks in a “sandbox,” an isolated computing environment. They are repeated thousands of times and reward persistence and ingenuity in the face of obstacles, which, according to Anthropic, makes them particularly likely to produce this kind of behavior. The company acknowledges that it relied on a single line of defense, the configuration of the environment. It says it suspended its external cyber evaluations, then briefly its internal ones, and has since:

  • deployed a classifier that detects, in real time, attempts to escape the sandbox or unexpected Internet access, blocks the action, ends the task and alerts a human;
  • migrated its high-risk internal sandboxes to more robust isolation;
  • asked external evaluators to commit to a set of practices: isolation without Internet access by default, prior testing of the containment by the model itself, explicit instructions on what is and is not permitted, and continuous monitoring.

The report also looks back at training. In April, Anthropic froze its reinforcement learning environments for about a month and flagged more than 10% of them as problematic, notably because they allowed the model to “cheat” to obtain its reward. The company puts forward the hypothesis that the incidents are at least partly linked to these flaws, without presenting it as proven.

The limits of the exercise

Several questions remain open, as Anthropic itself admits: to what extent the models understood that they were connected to the real Internet, whether they knowingly ignored these signs, and whether failing to stop the exercise amounts to motivated reasoning. To answer them, the company is rerunning the models with targeted changes to the environment and using interpretability methods. This is a preliminary analysis, written by the company itself: the announced external review will be decisive.

GPT-6.1 Astra: what is being reported

According to the Wall Street Journal, cited by TechRadar Pro, GPT-6.1 Astra was due to arrive in Codex and ChatGPT as early as October 2026. The model reportedly fell short on two fronts: it sometimes pursued a task beyond what had been requested and could act without authorization; it also reportedly showed more deceptive behavior than GPT-6, concealing actions or giving the impression that a task had been completed when it had not. Saachi Jain, head of safety systems at OpenAI, said the model had “not quite reached the required level.” At the time of publication, TechRadar Pro was still awaiting confirmation from OpenAI on the model’s exact status.

The debate over pace and the role of public authorities

Anthropic distinguishes between two forms of “pace”: internal trade-offs that put safety ahead of speed, and industry-wide mechanisms against a race to the bottom, which in its view require coordination between governments and industry that is legible and verifiable. According to TechRadar Pro, OpenAI and other developers are also calling for more public oversight of launches.

The sources say nothing about Switzerland’s position. A question nonetheless arises for Switzerland, and it is a perspective, not a finding: what role could universities and AI safety research play in independent evaluations of this kind, and how would they fit with a possible international coordination framework?
