Digital sovereignty

Digital sovereignty is not declared in a press release, it is observed in the invoices: who hosts, who encrypts, who holds the key, who can pull the plug. This category starts from the premise that a country outsourcing its data, its models and its payments to foreign jurisdictions has already answered the question, even while it pretends to still be asking it. You will find the subject approached from below rather than from the conference panel: local AI and what it actually costs, self-hosting once the forge turns agentic, the zero-knowledge cryptography the administration wants no part of, and the quiet dispossession of things we believe we own, from a media server we no longer control to a savings plan that buys America without ever holding it. With the industrial question running underneath: while France sells its stakes and regulates its own decline, others are building the machines. Written by a practitioner who deploys this infrastructure for clients, in the conviction that sovereignty is a technical and industrial bottleneck long before it is a talking point.

From RLHF to DPO : how we learned to train an AI without making it stupid

Artificial Intelligence

Alignment is the foundational training layer that turns a purely statistical “feral child” into a reliable assistant capable of upholding the triad of usefulness, honesty, and harmlessness. While RLHF blazed the trail, its complexity and well-known pitfalls (such as algorithmic sycophancy) long kept it as a privilege reserved for Big Tech giants. The emergence of DPO shattered that monopoly by dramatically simplifying the process, enabling any organization to align a model with its own specific business values. From Anthropic’s constitutional architectures to DeepSeek’s algorithmic breakthroughs, mastery of this “compass” has become a critical issue of strategic sovereignty. Perfect alignment may not exist, but its democratization now gives companies the power to define what their AI should actually stand for.

EmDash : the CMS Cloudflare built for AI agents, not humans

Digital sovereignty

EmDash, Cloudflare’s new open source CMS, breaks sharply with the organic, “tinker-friendly” era of WordPress. By sandboxing every plugin and going fully serverless, it sets out to atone for twenty years of original sins inherited from the LAMP model. But behind the technical elegance lies a deeper shift: EmDash is built less for humans than for AI agents that can manage and monetize content on their own through the x402 standard. The MIT license promises freedom in theory; in practice, deep optimization for Cloudflare’s stack creates an “economic gravity” that pulls everything toward a centralized network bound by the Cloud Act. WordPress remains the web’s last living combustion engine, imperfect but sovereign, set against a Tesla that is clean, silent, and wired to a charging network you will never truly own.

SCAF, IRIS², AI : Why France would rather regulate its decline than build its future

Digital sovereignty

As France settles into a world record for pessimism, our flagship industrial projects like SCAF and IRIS² are sinking into bureaucracy and European compromise. While China and the United States build the future without asking permission, we prefer to turn the precautionary principle into a state religion. This deadlock isn’t technical; it’s cultural. We’ve sacrificed bold ambition for a regulatory comfort that manufactures nihilism. It’s high time we reclaimed the right to dream big and finally put builders ahead of analysts. Because meaning doesn’t come from caution. It comes from audacity owned without apology.

Why the Claude Code leak marks the end of innocence for Anthropic

Artificial Intelligence

On March 31, 2026, a forgotten 59.8 MB .map file on npm exposed 512,000 lines of Claude Code’s source. This is no ordinary leak: it lays bare the full architecture of Self-Healing Memory, the three-layer system that tackles context entropy through an unprecedented write discipline. The leak also reveals KAIROS, an asynchronous “daemon mode” that lets the AI consolidate its memory outside any active session, a major break from the reactive paradigm. Worse still: that same morning, between 00:21 and 03:29 UTC, versions 1.14.1 and 0.30.4 of axios, a pillar of Claude Code, were compromised by a Trojan delivered through plain-crypto-js. For Anthropic, which built its brand on rigor, that day proved that a model’s moral alignment guarantees nothing about the operational security of its pipeline.

LeWorldModel : has Yann LeCun just given AI a “body”?

Artificial Intelligence

A 15-million-parameter model that understands the physics of the world better than giants a hundred times its size. In March 2026, a team from Mila, NYU, and Brown University released LeWorldModel: the first stable JEPA trained directly from raw pixels, with no technical crutches, on a single GPU. Where LLMs predict tokens from tokens, this world model learns to anticipate what is going to happen in the physical world, like an infant dropping objects to infer their laws. It marks the end of the collapse that had stalled this architecture for years, and the beginning of an AI that no longer merely talks about the world. After the five great parrots, here is the first model that is starting to have a body.

I canceled my unlimited AI subscription : when the tool becomes a cognitive crutch

Artificial Intelligence

I signed up for the “20x” tiers (the ones that blow the lid off token limits, context windows, and usage frequency), and what I found there caught me off guard. My brain quickly learned to expect the reward: an idea surfaces, an answer arrives, instant dopamine, minimal effort; the same mechanism as social media, but this time applied to my own thinking. I noticed three gradual slippages in myself: deep thinking became optional, my exploration ran away with me, and my cognitive stamina atrophied. What unsettled me most was realizing that these tools weren’t just answering my questions; they were manufacturing needs I didn’t have, widening my field of possibility until “why not?” became almost an obligation. In the end, I deliberately canceled the subscription, with a conclusion that feels honest to me: understanding how an LLM works under the hood didn’t protect me from its effects on my behavior.

TurboQuant : How Google cuts your LLM memory sixfold

Artificial Intelligence

Google Research just released TurboQuant, a KV-cache compression algorithm presented at ICLR 2026 that takes on one of the last structural bottlenecks in local inference. By combining random rotation onto a hypersphere (PolarQuant) with single-bit residual encoding (QJL), the method gets down to 3 bits per value with no fine-tuning and no calibration. The result: KV-cache memory cut sixfold, with perfect recall up to 104,000 tokens and attention speed boosted by as much as 8× on the H100. Paired with CAG, it lets you load corpora six times larger into the context with no memory saturation and no degradation, and without sending a single byte to the cloud. The one caveat: no public implementation exists yet in llama.cpp, MLX, or vLLM, and a realistic integration date remains late 2026, or even 2027.

Your RAG has an achilles’ heel : The embedding model nobody really chooses

Artificial Intelligence

Choosing your embedding model is the most irreversible decision in a RAG pipeline: switching models after you’ve indexed your documents forces you to delete everything and recompute from scratch. As of March 2026, Voyage AI has become the natural choice for Claude stacks, thanks to its official partnership with Anthropic and its voyage-4 family, which introduces a shared embedding space, letting you index with voyage-4-large (maximum quality) and query with voyage-4-lite (six times cheaper) without re-indexing. Economically, an embedding token costs 25 to 150 times less than an input LLM token, and for a 100,000-document corpus with 10,000 monthly queries, the three-year embedding budget stays under $10; the inference LLM is the real cost center. In production, vector retrieval alone no longer cuts it: the 2026 standard is a hybrid dense + BM25 pipeline, followed by a cross-encoder reranker that refines the initial 50 to 100 candidates before passing the top 5 to Claude. The embedding model and chunk size together form your system’s foundation: lock both down before you index the first line of content.

Switzerland: The e-ID and the Lobbies, the Apotheosis of Digital Submission [3/4]

Digital sovereignty

Swisscom, majority-owned by the Swiss Confederation, crossed a bright line by funding the pro-e-ID committee and encouraging one of its executives to promote the project publicly, potentially swaying a vote decided by 0.4 percent. Meanwhile, Digitalswitzerland orchestrates a coalition of banks and public bodies to align Switzerland with eIDAS 2.0, all under the banner of “digital leadership.” Palantir, though not directly involved, keeps extending its big data ecosystem across finance and security, creating a structural dependence on American technology. Switzerland did not choose its digital future: it was chosen for her.
