A Patchwork of Governance: Anthropic’s Fable 5.1
Word count: 491
1. AI Model: Claude Fable 5.1: Anthropic board: non-state
Source of authority: Anthropic creates its own authority as a Delaware-based corporation and through creating the infrastructure of Claude including its own safeguards.
Governing instrument: Anthropic governs itself with its own board and Responsibility Scaling Policy (RSP). Its latest risk report is from August 2026 and its most updated Responsible Scaling Policy is from July 8, 2026. It’s worth noting Anthropic references catastrophic risk/harm/damages 20 times in its report.
Interest/Value it purports to protect: According to its own RSP it purports “Anticipating and securing against emerging threats that accompany increasingly powerful models.” In other words, preventing misuse and catastrophic risk.
One weakness in its accountability: Anthropic governs itself. There is no external oversight board to say whether or not it is doing a good or even basic job.
2. SB-53 Artificial intelligence models: large developers: California State/Public
Source of authority: Article IV of California Constitution, the “Artificial intelligence models: large developers” bill passed both houses and Governor Newsom signed it September 29, 2025.
Governing instrument: California Constitution
Interest/Value it purports to protect: The public from “catastrophic risk” as described from Chapter 138, Section 1, by requiring “a summary of any assessment of catastrophic risk, as defined, resulting from internal use of its frontier models, as specified.”
One weakness in its accountability: AI companies, including Anthropic, create their own framework against which they are evaluated. Section (1) 22757.12. (a).
3. Executive Order 14409: Federal/Public
Source of authority: Article II of the Constitution. It is worth noting there is no comprehensive federal law governing AI in the United States, just Executive Orders.
Governing instrument: Executive Order 14409
Interest/Value it purports to protect: National security & cybersecurity
“(a) develop and maintain a classified benchmarking process to assess the advanced cyber capabilities of AI models and determine the threshold at which an AI model should be designated a “covered frontier model” for the purposes of this order, sharing such assessments with AI developers and researchers as appropriate.”
One weakness in its accountability: Benchmarks judging the models are classified and set by NSA director, and no court section 5(c) no rights enforceable in court – also it’s a “voluntary framework.”
4. European Union: Regulation (EU) 2024/1689 of the European Parliament and of the Council
Source of authority: AI Act / Treaty on the Functioning of the EU Articles 16 and 114
Governing instrument: AI Act, Regulation (EU) 2024/1689, Chapter V on general AI models.
Interest/Value it purports to protect: Article 1 (1) “to promote the uptake of human centric and trustworthy artificial intelligence (AI)” to ensure the protection of health, safety, and fundamental rights.
One weakness in its accountability: AI companies check their own work. Article 43 (2) “providers shall follow the conformity assessment procedure based on internal control as referred to in Annex VI, which does not provide for the involvement of a notified body.”
