Enlightening thread on Proton's new LLM
social.cryptography.dog/@ansuz

ansuz / ऐरन (@ansuz@social.cryptography.dog)
I know that a bunch of people in my general region of the fediverse already stopped using #Proton because of their CEO's fascist inclinations, and that if you're following me you're probably already sick of generative AI. Even so, I feel like this is worth pointing out if only for harm reduction. Proton has introduced their own LLM model, or perhaps an integration of an existing "open-source" model (the OSI's definition, presumably) which they haven't credited: https://proton.me/blog/lumo-ai …

Towards Provable (In)Secure Model Weight Release Schemes
Recent secure weight release schemes claim to enable open-source model distribution while protecting model ownership and preventing misuse. However, these approaches lack rigorous security foundations and provide only informal security guarantees. Inspired by established works in cryptography, we formalize the security of weight release schemes by introducing several concrete security definitions. We then demonstrate our definition's utility through a case study of TaylorMLP, a prominent secure…

DefElement: an encyclopedia of finite element definitions
DefElement is an online encyclopedia of finite element definitions that was created and is maintained by the authors of this paper. DefElement aims to make information about elements defined in the literature easily available in a standard format. There are a number of open-source finite element libraries available, and it can be difficult to check that an implementation of an element in a library matches the element's definition in the literature or implementation in another library, especiall…

A Formal Model of the Economic Impacts of AI Openness Regulation
Regulatory frameworks, such as the EU AI Act, encourage openness of general-purpose AI models by offering legal exemptions for "open-source" models. Despite this legislative attention on openness, the definition of open-source foundation models remains ambiguous. This paper models the strategic interactions among the creator of a general-purpose model (the generalist) and the entity that fine-tunes the general-purpose model to a specialized domain or task (the specialist), in response to regula…
