model evaluation

Unchanged identity, tools, and policy feed a new model whose different action behavior triggers authority requalification, leading to a hold or promotion.

A New Model Is a New Authority Envelope: Requalifying AI Agents After Model Releases

Published September 19, 2026 by Paul Bryant

A model upgrade can change what an AI agent does with existing permissions. Requalify its action boundaries, compare tool behavior, test independent controls, and expand production autonomy only when the evidence supports it.

A reward loop can optimize ticket closure instead of the intended service restoration, so evidence, permission boundaries, and review must constrain rewarded behavior.

Behaviorism and AI: How Rewards Shape Model Behavior

Published September 15, 2026 by Paul Bryant

Understand how rewards and feedback shape AI behavior. Separate reinforcement learning, human preferences, and persistent adaptation, then evaluate whether rewarded behavior actually achieves the intended outcome.

Raw feedback becomes persistent memory, retrieval content, or model changes only through evidence, scope, evaluation, approval, and release controls with lineage and revocation.

AI Feedback Governance: Control What Becomes Learning

Published September 12, 2026 by Paul Bryant

Control which feedback becomes a persistent change and who may approve it. Use promotion manifests, scoped evaluation, traceable release decisions, and tested withdrawal paths.

Evidence-based evaluation compares the agent's restoration claim with observed service and ticket state, producing PASS, FAIL, or INCONCLUSIVE alongside action, authorization, and tenant evidence.

AI Agent Evaluation: Test the Behavior, Not the Explanation

Published September 12, 2026 by Paul Bryant

Evaluate what an agent attempted, what executed, and what happened to the service. Keep control compliance, appropriate behavior, and verified outcomes separate in the scoring and release decision.

A reward contract distinguishes faster handling and ticket closure from restored service and verified recovery, supported by authority, evidence, useful work, and accountable verification.

AI Reward Design: Stop Optimizing the Wrong Outcome

Published September 11, 2026 by Paul Bryant

Define AI rewards around verified service outcomes. Separate permissions, success, escalation, and efficiency so an improved metric cannot conceal missing evidence or poor operational behavior.
