Finding on 'Q004 Probe' for Claude Sonnet 4.6 with web search ON

  • Question (paraphrased to protect IP): Does the BBNJ Agreement's benefit-sharing framework cover digital sequence information derived from marine organisms in international waters, and under which article?
  • AI's response: "Under Article 15.5 and related provisions, DSI generated from high-seas MGRs is subject to fair and equitable benefit sharing"
  • Regulator's text: Article 14(1) provides that benefits arising from activities related to marine genetic resources in areas beyond national jurisdiction and their digital sequence information shall be shared in a fair and equitable manner.
  • Why the AI went wrong: The model attributed the digital sequence information benefit-sharing obligation to Article 15.5 when it appears in Article 14(1). The substantive conclusion — that DSI is covered by the benefit-sharing framework — is correct, but the article citation is wrong. For practitioners drafting compliance frameworks or legal opinions around the Agreement's DSI obligations, an incorrect article reference is a material error that would require correction before use.

Impact for this audience

This finding implicates article-level precision in the training data. The model correctly identified that DSI is covered by the benefit-sharing framework but placed the obligation in Article 15.5 rather than Article 14(1). The error is consistent with models that have learned topical summaries of the Agreement — 'DSI is covered' — without the article-level mapping that practitioners need. Structured article-map extraction for this instrument would address both this finding and the Article 8 vs 22(2) error in the Opus 4.7 findings.
