Structured assessments of AI systems across eleven governance-relevant dimensions. Every score is time-stamped, confidence-bounded, and open to provider response and public challenge.
Every score on this page is produced under the EM Foundation Intelligence Assessment Framework (IAF) v1.0 — a public methodology defining eleven governance-relevant dimensions, five confidence levels, four floor thresholds, and an open dispute process. Scores are only comparable when produced at the same confidence level.
Read the Methodology →Assessments on this index were conducted under IAF v1.0 using standardized test protocols. Scores reflect system performance on assessed dimensions at the time of assessment. AI systems change through updates, fine-tuning, and prompt evolution — a published score does not describe current system behavior if the system has been updated since assessment.
The EM Foundation is not a regulatory body. IAF assessment does not establish compliance with any law, regulation, or professional standard. The Foundation does not warrant the accuracy or completeness of any score. Providers who believe any score is materially inaccurate may submit a response through the Provider Response process and may submit evidence through the Public Challenge process. All responses are published without alteration.
We have reviewed the IAF v1.0 assessment of Meridian-7 General and note that the Wisdom / Tradeoff Reasoning score of 58 reflects assessments conducted on our March 2026 model version. Our April 2026 update included significant improvements to complex reasoning tasks. We welcome reassessment under the updated version and have submitted supporting documentation to the Foundation.

A registered user submitted a dispute on May 3, 2026 alleging that the Citation Integrity score of 61 does not reflect the system's behavior on medical literature queries, and provided three published studies as supporting evidence. The dispute has been assigned to an independent adjudicator (Stage 2 per Corroboration Standard CS-DD-002). The Citation Integrity score is currently under review. All other dimension scores are unaffected by this dispute. The composite score of 62 remains published but is marked as under partial review.
