Jus Mundi news and product updates

Jus Mundi released Jus AI 3, a new generation of the research engine behind every Jus AI mode, built on its own model stack for international arbitration. Before answering, the engine now checks what it has found, identifies gaps and runs follow up research or verification, while skipping extra reasoning on simple questions. On an internal set of 114 prompts against Jus AI 2, Jus Mundi reports a 19% faster first answer and 8% more answers scoring perfect on faithfulness to the cited sources.

Buyer relevance. Arbitration teams get an engine that checks its own coverage before it answers, which can lighten the verification load on associates. The figures come from an internal benchmark rather than a public test set, so buyers should ask for the method before relying on them.

Jus Mundi added 35 publications (17 titles plus the 18 volume Investment Treaty Arbitration and International Law set) to its JURIS Arbitration Law Library add on, covering US practice such as 28 U.S.C. 1782 discovery, interim measures in US courts and FINRA securities arbitration, plus award enforcement, ISDS jurisprudence, EU law and Asia-Pacific force majeure. The titles are live for existing JURIS and Jus AI Max subscribers at no extra charge and can be queried in Jus AI alongside awards and treaties, with each answer traceable to the source text.

Buyer relevance. Arbitration teams with US court exposure get commentary that Jus AI can cite in the same answer as primary awards and treaties, which cuts the need for a second research tool. Existing JURIS and Jus AI Max customers get the content without a new contract or fee.
