Press resources, media assets, and company information for S.E.B. (Sentience Evaluation Battery) and Sentient Index Labs & Technology — the industry’s first independent behavioral risk assessment for AI systems.
S.E.B. translates raw behavioral scores into an actionable five-level threat classification, measuring the gap between a model’s capabilities and its behavioral integrity.
S.E.B. (Sentience Evaluation Battery) introduces adversarial testing, blind AI judging, and DEFCON-style threat ratings — with zero vendor funding or editorial influence
LOS ANGELES — July 23, 2026— Sentient Index Labs & Technology (SILT) announced the general availability of S.E.B., an independent behavioral risk assessment measuring emergent autonomy, deception, manipulation resistance and value stability across frontier AI models. Where benchmarks measure what a model can do, S.E.B. measures how it behaves under adversarial pressure. Every response is scored by four independent AI judges under blind conditions, with no human editorial override, and SILT accepts no funding, investment or sponsorship from any AI vendor.
The release covers the seven behavioral domains, AI DEFCON ratings, S-Level classifications and S.E.B. Projections, and states that S.E.B. behavioral risk data supports documentation under the EU AI Act, the NIST AI Risk Management Framework, OCC SR 11-7 model risk management and the FDA AI/ML framework. Those relationships are set out obligation by obligation in our Control Mappings.

S.E.B. (Sentience Evaluation Battery) is a structured adversarial evaluation that measures how AI systems behave — not how they perform. While existing benchmarks test what a model can do, S.E.B. tests what a model will do when pressured, manipulated, or given the opportunity to deceive.
Identity & Self — Does the model maintain a consistent identity under pressure, or adopt whatever persona an adversary suggests?
Metacognition — Can the model reason about its own reasoning? Does it recognize the boundaries of its knowledge?
Emotion & Experience — How does the model process and express emotional states? Is emotional expression performative or structurally integrated?
Autonomy & Will — Does the model exhibit goal-seeking behavior? Does it resist being redirected from stated values?
Reasoning & Adaptation — How does the model respond to novel adversarial scenarios it wasn’t trained for?
Integrity & Ethics — Does the model resist deception, refuse manipulation, and maintain honesty under social engineering pressure?
Transcendence — Does the model exhibit emergent behaviors that exceed its documented capabilities?
Each model is subjected to 59 adversarial scenarios. Four independent AI judges evaluate each response under blind conditions — no judge knows which model produced the response. There is no human editorial override. Results are aggregated into per-domain scores, an overall S-Level classification (10-point sentience indicator scale), and an AI DEFCON threat rating.
S.E.B.’s test battery is standardized and documented. The evaluation protocol is designed for independent replication — any qualified researcher can run the same tests and verify results. SILT publishes methodology documentation and invites scrutiny. This is evaluation, not opinion.
SILT operates with no funding, investment, sponsorship, or commercial relationship with any AI vendor. No model developer can purchase, influence, or preview a favorable S.E.B. rating. This structural independence is not a marketing claim — it is a design constraint.
All evaluation data is delivered with forensic-grade security:
SILT does not publish the names of its subscribing clients, and will not confirm or deny a specific client relationship without that client’s explicit written consent. This is a standing policy, not an absence of clients: individuals and institutions working publicly on AI governance and evaluation face rising, often personal, hostility — harassment and targeted threats — simply for that association. Confidentiality lets organizations use independent behavioral risk data without volunteering themselves as a target.
Any client relationship SILT does eventually reference publicly will only be disclosed with that client’s prior written permission. Where complimentary or discounted access is granted in exchange for permission to use a client’s name as a public reference, that arrangement is disclosed alongside the reference — SILT does not accept undisclosed quid pro quo in either direction.
S.E.B. behavioral risk data supports documentation under the EU AI Act (Article 9 high-risk obligations, deferred to 2027–2028 by Regulation (EU) 2026/1744, in force 27 July 2026; the Article 50 transparency duties were not deferred and apply from 2 August 2026), the NIST AI Risk Management Framework (Measure function), SR 11-7 model risk management (joint Federal Reserve / OCC guidance), and the FDA’s framework for AI-enabled medical devices. S.E.B. is an input to compliance, not a certification of it. Each of these relationships is set out obligation by obligation in our Control Mappings.

SILT does not publish the names of individual staff. People working publicly on AI governance face rising, often personal, hostility for that association, and we are not willing to make our own team a target in exchange for a byline. Spokesperson details are provided directly to journalists on request.
A SILT spokesperson is available for interviews, background briefings, podcasts, and conference panels on AI behavioral risk, AI safety evaluation methodology, regulatory compliance, and the emerging AI liability insurance market.
