It's not only Harvard. Universities worldwide have made conracts with AI companies, paying to get more tokens and/or tokens for more advanced LLMs. And yet, some people have "their" research stopped because they run out of tokens. All of this in the current times of scarce and dwindling funding.

In case you'd like to try reading more than marketing claims and press coverage, this review article covers what makes it feel like LLMs do more than stringing together tokens: doi.org/10.5281/zeno... Includes recent research showing the brittleness of 'reasoning' that experts here refer to
Although text-generating large language models have existed since 2018, it is only in the last few years that people have started to talk to them in earnest. The main reason is a series of innovations that enabled engineers to better tailor model output to human preferences and present it in a chat interface. Suddenly language models seemed to be much more than synthetic text extruding machine s (Bender and Hanna 2025) : they behaved as if following instructions, responded in ways that felt intuitive , and even seemed to have a mind of their own (Kockelman 2024). This interactivity, to a large degree enabled by unseen human labour, turned out to be tremendously compelling. My aim here is to demystify this phenomenon and so contribute some  interactional building blocks to the sprawling edifice of critical AI literacies (Guest et al. 2026).Research that looks behind the curtains of benchmark results finds something quite different. One study by Anthropic researchers found that chain-of-thought traces often “systematically misrepresent the true reason for a model’s prediction” and identified a range of biasing features that made explanation-shaped model output “plausible yet systematically unfaithful” (Turpin et al. 2023, emphasis theirs) . Another study found that large language models, even if they deliver plausible output, “often arrive at correct answers through incorrect reasoning” (Nguyen et al. 2024). Even when tested on simple syllogistic reasoning , model performance is highly brittle and susceptible to stylistic perturbations (Ariyani et al. 2025) . In multiple choice question answering, the simple inclusion of an answer like “none of the other answers”, which requires real reasoning rather than stumbling around in latent space, leads to average model performance dropping from 66% correct to 31% correct on MMLU questions  (Salido et al. 2026) . Meanwhile correct answers turn out to be hard to come by for truly new problems: when eight state -of-the-art models were tested on a set of brand new reasoning problems from the 2025 USA Math Olympiad, all performed dismally , and inspecting the “reasoning traces”, researchers found failures of logic, wrong assumptions, inability to choose between approaches, and miscalculations (Petrov et al. 2025).

noblogs.org maintainers Collettivo Autistici / Inventati, have been declared terrorist organisation by the U.S. cavallette.noblogs.org/2026/08/10076
Today we were made aware that the US Government has targeted a small, volunteer-run, technology collective from Italy with disproportionate sanctions as anyone can read in the Treasury Department Statement, the State Department Statement and the related Executive Order.

We deny all allegations included in the statements, while we strongly affirm our dedication to providing a platform of tools for digital self-defense, addressing the need of free communication for activists and other individuals, groups and associations.

We will not back down, we will keep doing what we have been doing all these years and we will do whatever is in our possibility to counter the false allegations made by a politically desperate administration with the sole intention of swaying people and media attention away from their own violence and warmongering. 

Antifascism and anticapitalism are not terrorism. Protesting is not terrorism. And everyone has the right to speak out and to struggle for humanity.

"The incidents have rattled security specialists and computer scientists.
