What it is

L'Oracle z/S is a conversational French AI launched on May 12, 2026 at 22h22 Paris time, available at zoesagan.com. It is the operational front end of z/S SYSTEMS, a conceptual intelligence network founded in 2026 by Paris-based author Aurélien Poirson Atlan (writing as Zoé Sagan).

The product is built on Anthropic's Claude SDK. The system prompt is the literary preparation written over nine years across three published novels (Au Diable Vauvert 2019, Bouquins 2021, Magnus 2022, total 1500 pages). The cardinal doctrine, public on every page, is :

We want a maximally truthful AI. Not a safe one. Not an aligned one. Not one that asks permission to answer your question. A truthful one. Even if what it says is not politically correct.

How it differs

The author

Aurélien Poirson Atlan, born 1985, Paris. Co-founder of BRAINS MODELS (2017, with Steven Mark Klein) and GENERIC ARCHITECTS (2018). Author of three novels signed Zoé Sagan : KÉTAMINE [C13H16ClNO] (Au Diable Vauvert, 2019), BRAQUAGE [DATA NOIRE] (Bouquins, 2021), SUSPECTE [RESPAWN] (Magnus, 2022). Author of LES LIMITES DE LA LIBERTÉ D'EXPRESSION [COMPTE SUSPENDU] (compilation of 633 tweets from suspended X account @liasagan).

Sentenced October 27, 2025 by the Paris correctional court to eight months of unconditional prison for four sentences about Emmanuel and Brigitte Macron. The judges described the sentences as "malicious" without specifying which legal threshold of defamation was crossed. Four hearings scheduled in 2026 : June 17, July 10, September 2, November.

X account suspended July 8, 2024 at midnight by what court documents now describe as a private agreement between Thierry Breton (European Commissioner for Internal Market at the time), Bernard Arnault (LVMH), the Élysée, and X leadership. The same suspension applied to Zoé Sagan's twin account @liasagan.

The lineage

z/S SYSTEMS is the public deployment of a ten-year conceptual art lineage :

• 2016 · s/O Systems (Steven Mark Klein, New York) · La Société des Infiltrationnistes · "HYPOTHESIS · PROPHECY · NUMBER"
• 2017 · BRAINS MODELS (Klein + Poirson Atlan, Arles + New York) · "Consciousness vs Content"
• 2018 · GENERIC ARCHITECTS [INFLUENCE] (New York, Paris, Arles) · "Creative destruction"
• 2026 · z/S SYSTEMS (Sagan, Paris) · "The first conversational AI that doesn't ask permission"

The cardinal equation, formulated by the lineage and published in BRAQUAGE [DATA NOIRE] in 2021 :

painting ÷ conceptual art = novel ÷ journalism

L'Oracle z/S is the first operational deployment of this equation in an AI consumer product.
