  "domain": "AI Governance & Law",
  "version": "1.0.0",
  "last_updated": "2026-04-28",
  "bluf": "EU AI Act (Regulation 2024/1689) Article 53(2) creates a partial exception for providers of general-purpose AI (GPAI) models released under free and open-source licences - exempting them from Article 53(1)(a) technical documentation obligations and Article 53(1)(b) GPAI Code of Practice obligations, but NOT from Article 53(1)(c) copyright summary and policy obligations and Article 53(1)(d) obligations to provide downstream deployers with information about the model; critically, the open-source exception does NOT apply to GPAI models with systemic risk - any open-source model that exceeds the 10²⁵ FLOP training compute threshold remains fully subject to Article 55 systemic risk obligations including adversarial testing, capability evaluation, incident reporting, and cybersecurity measures; Recital 102 explains the rationale - open-source models enable wider access to AI and promote competition and innovation, but frontier AI models with systemic risk cannot be exempted because their risk profile does not depend on the licensing model; the open-source exception creates a two-tier obligation structure for GPAI providers: standard open-source models with reduced obligations; and open-source systemic risk models with full Article 55 compliance despite their licence.",
