Sentient Index Labs & Technology (SILT) announced the general availability of S.E.B. (Sentience Evaluation Battery), the first independent behavioral risk assessment for AI systems, measuring emergent autonomy, deception, manipulation resistance, and value stability. The battery runs 58 tests across seven behavioral domains, scored by four independent AI judges under blind protocols with no human editorial override. Inter-rater agreement stands at Krippendorff's alpha = 0.856. S.E.B. currently evaluates frontier models from OpenAI, Anthropic, Google, xAI, and DeepSeek. Results are delivered as AI DEFCON ratings, S-Level classifications (a 10-point sentience-indicator scale), and S.E.B. Projections. SILT accepts no funding, investment, or sponsorship from any AI vendor, and no model developer can purchase, influence, or preview a rating. S.E.B. behavioral risk data supports documentation under the EU AI Act (Article 9 high-risk obligations, phasing in 2027–2028), the NIST AI Risk Management Framework, OCC SR 11-7 model risk management, and the FDA AI/ML (SaMD) framework. Evaluations are available now by subscription at silt-seb.com.
