It is long (four documents, 230 control objectives, more than 500 pages) and new, so will take some time to work through properly. Of interest, the U.S. Treasury also released an [AI Lexicon](https://fsscc.org/wp-content/uploads/2026/02/AIEOG-AI-Lexicon-February-2026.pdf), created by the Artificial Intelligence Executive Oversight Group (described in the document). It is different to [NIST’s Trustworthy AI Glossary](https://riskinsights.com.au/blog/curated-insight-nist-trustworthy-ai-glossary): - shorter, at 9 pages (vs 22) - maps a single definition to each term (vs multiple definitions per term) - is meant to be FS focused (e.g. it defines “Algorithmic trading system”).   ## Highlights (of the Lexicon) It adopts definitions from NIST (e.g. from the [Risk Management Framework for Information Systems and Organisations](https://nvlpubs.nist.gov/nistpubs/SpecialPublications/NIST.SP.800-37r2.pdf)), the Comptroller’s Handbook ([Model Risk Management](https://www.occ.treas.gov/publications-and-resources/publications/comptrollers-handbook/files/model-risk-management/pub-ch-model-risk.pdf)), and other sources. Notably, it: - was “developed to promote a shared vocabulary for communication and collaboration on AI related matters in the financial sector.” - “compiles commonly used risk management and technical terms that have specific meanings in the context of AI use in financial services.” - is “an optional tool and is not intended for use…” in legal interpretations, etc.   It could help reduce arguments within (and between) teams and become a handy reference point.   The AI lexicon is available here: [https://fsscc.org/wp-content/uploads/2026/02/AIEOG-AI-Lexicon-February-2026.pdf](https://fsscc.org/wp-content/uploads/2026/02/AIEOG-AI-Lexicon-February-2026.pdf) If you have the time and inclination, the FS AI RMF is here: [https://cyberriskinstitute.org/artificial-intelligence-risk-management/](https://cyberriskinstitute.org/artificial-intelligence-risk-management/)   --- Disclaimer: The info in this article is not legal advice.
