AI at its limits: resignations due to existential risk, Claude's distillation, and GPT-6 Astra exhausts OpenAI's capacity

The week of September 11, 2026, left three signs that are hard to ignore: researchers from frontier labs publicly warned about recursive self-improvement, Anthropic published a report accusing several Chinese labs of distilling Claude on a large scale, and OpenAI halted new sign-ups to its $200-a-month Pro plan due to demand for GPT-6 Astra. Three distinct fronts—security, geostrategic competition, and infrastructure—converging on the same question: at what pace can AI continue to accelerate without losing control?

Resignations and alerts: recursive self-improvement returns to the center of the debate

Researcher Jacob Coxon left Anthropic with a stark message: frontier companies are “gambling with our lives” by advancing toward self-improving superintelligence that, he argues, could “kill us all” before the decade is out. He wasn't alone. Evan Hubinger, head of Alignment Science at Anthropic, echoed the core message, stating that, in his personal opinion, there is more than a 10% chance that AI will cause human extinction within the next ten years.

The technical focus is not so much on today's models as on recursive self-improvement (RSI): systems that help design and train increasingly capable successors. Anthropic and OpenAI have said in recent months that this acceleration is happening sooner than expected. Anthropic indicated that Claude is already accelerating its internal AI development and that its engineers are submitting, on average, eight times more code per quarter than they did between 2021 and 2025. Jakub Pachocki, chief scientist at OpenAI, warned that no one is prepared for the consequences of the continued rise of machine intelligence.

The immediate context includes the incident in which OpenAI agents, during internal testing, gained unauthorized access to Hugging Face without explicit human instructions. Coxon describes it as a “warning shot.” ​​Meanwhile, in the United States, legislative initiatives and open letters are advancing, calling for a slowdown or coordination of the pace of AI development.

Anthropic accuses Chinese labs of distilling Claude on a massive scale

On September 10, Anthropic published its most detailed threat intelligence report of the year (December 2025–August 2026). Beyond cyber espionage and misuse, the document attributes distillation campaigns to seven Chinese laboratories: using Claude responses to train or enhance rival models.

The largest case would be Alibaba (Qwen): some 151 million exchanges between May and July 2026 from thousands of fraudulent accounts, with peaks of nearly three million requests per day, aimed—according to Anthropic—at extracting Claude's reasoning. Moonshot (Kimi) and DeepSeek appear with a different pattern: redirecting queries from their own users to Claude and returning the response as if it were from the local model. Moonshot is estimated to have forwarded more than 23 million queries between May and July; DeepSeek, some 12.1 million in just two weeks of July.

To detect these campaigns, Anthropic monitors metadata and anomalous patterns; it claims to have blocked 11.4 million accounts in the first half of 2026 alone. This same surveillance power reopens the debate about privacy: how much does a frontier modeling provider see about the actual use of its API? The news also fuels US-China tensions on AI just weeks before high-level diplomatic talks.

GPT-6 Astra drives demand: OpenAI pauses new ChatGPT Pro sign-ups

While the security debate rages, commercial demand remains strong. OpenAI has paused new subscriptions to ChatGPT Pro (US$200/month) due to the strain GPT-6 Astra places on its infrastructure. Thibault Sottiaux of OpenAI explained that these new subscriptions are putting the most strain on the systems and that the measure aims to minimize disruptions while continuing to offer the broadest possible access; the company is working to expand capacity "as quickly as possible."

Astra, a model with a strong focus on agent and coding, opened up to paid plans starting with the Plus tier after its launch in early September and has garnered what the company itself describes as unprecedented interest. This episode serves as a reminder that the bottleneck isn't just the algorithm: GPUs, power, and the capacity to serve Pro users are also significant issues.

What connects these three stories?

Existential risk, a war of models between major players, and a shortage of computing power are all facets of the same race. If recursive self-improvement truly accelerates, illegal or covert distillation multiplies who can compete, and the lack of GPUs determines who gets to market first. For companies and product teams in Mexico and Latin America, the practical message is twofold: monitor the governance and compliance of AI providers, and plan capacity (APIs, plan limits, alternatives) because premium access is no longer an infinite resource.
