For each industry subsector and operating function: AEGIS pillar activation, regulatory obligations, practical governance considerations, and a concrete frontier model and enterprise platform architecture for the reimagined agentic service flow.
Function stacks use the 8 Oct 2026 default. GPT-6 is rolling across ChatGPT tiers; Astra remains the API / Azure / Bedrock path and some enterprise workspaces stay enablement-gated. GPT-5.6 remains the supported fallback. GPT-5.5 and Gemini 3.1 Pro are prior-GA. OpenAI DevDay was 29 September 2026; treat post-DevDay SKUs as GA only where the vendor page says so. Claude Haiku 5.5 (7 Oct) is the cheap routing tier.
ChatGPT tiers began moving to GPT-6 in early October (Sol for paid; Luna for Free/Go from 8 Oct; Enterprise still depends on admin settings). Astra remains the API (gpt-6-astra), Azure, and Bedrock path. GPT-5.6 Sol / Terra / Luna remains the supported fallback. GPT-5.5 is prior-GA.
Gemini 3.8 Flash GA 2 September 2026; Gemini 3.8 Live and Live Extended Thinking for enterprise voice agents mid-September. Gemini 3.5 Pro is no longer the preview to watch. Use 3.8 for new production architectures.
Fable 5.1 is generally available (API, Bedrock, Foundry, Vertex) as of 1 September 2026 for long-horizon agentic work. Mythos 5.1 is the same model with more permissive safeguards, invite-only under Project Glasswing, currently a set of US organizations. Architect against Opus 5 and Sonnet 5. Opus 4.8 and Sonnet 4.6 remain supported legacy.
The most regulated AI deployment context in the US and EU. Every consequential decision: lending, investment, insurance, fraud: triggers overlapping federal and state disclosure, fairness, and explainability obligations. Named operator evidence: Claude at JPMorgan Chase (Jul 2026). US bank model-risk guidance is SR 26-2 / OCC 2026-13 as of 17 April 2026; generative and agentic AI are outside that letter. State examiners can use the CSBS AI Supervisory Framework (16 Sep 2026, discretionary): action limits, human checkpoints, logging, reversibility, halt.
The intersection of FDA SaMD regulation, HIPAA data obligations, EU AI Act Annex III high-risk classification, and clinical liability creates the most complex AI governance environment of any sector.
Agentic AI in manufacturing operates at the intersection of OT/IT security boundaries, EU AI Act safety system obligations, ISO 42001 procurement requirements, and product liability risk. The governance stakes are physical as well as regulatory.
The binding constraint is the interconnection queue and the engineering headcount that clears it, not model capability. NERC CIP and NIS2 make a compromised or drifting grid agent a critical-infrastructure event. The working pattern, as of September 2026, is an agent that runs the utility's own study tooling rather than a chatbot that comments on it.
