LARGE-LANGUAGE MODELS
A stable frontier-model foundation for agentic commercial work.
SEQUESTO runs most work on one primary model family and upgrades deliberately to the latest capable release. The architecture can evolve as models improve, but the priority is stability, quality, and consistency for the teams working on top of it.
This layer is less about chasing providers and more about giving the rest of the platform a dependable intelligence foundation.
MODEL FOUNDATION
Stability before switching.
Most day-to-day work runs on one primary model family. That gives the platform predictable behaviour, cleaner evaluation loops, and less operational drift than constantly jumping between providers.
FRONTIER QUALITY
Frontier class by design.
The chosen model layer has to perform where commercial teams feel it most: understanding long documents, following structure, using tools correctly, and maintaining quality through multi-step work.
AGENTIC EXECUTION
One foundation, many executions.
James and the sub-agents may take on different jobs, but most of that work still relies on the same underlying model family. The architecture can route special cases when needed without turning model choice into daily operational overhead.
FUTURE-PROOF
Future-proof architecture.
The model market will keep moving. SEQUESTO absorbs that change at the platform layer so customer workflows, knowledge, and working habits do not need to be rebuilt every time the landscape shifts.

Agentic Harness
The Agentic Harness is the substrate behind how work gets executed in SEQUESTO aOS. It governs tool use, function calling, memory, reasoning, observability, and runtime safety so each task is assembled around the user’s request instead of pushed through one static chain.
Learn more →Agent Force
Agent Force is the specialist layer on top of the harness. James orchestrates the work, while specialist agents handle extraction, drafting support, review support, and document operations across tenders, questionnaires, and structured commercial work. The heavy lifting scales, but the final wording and approval stay human.
Learn more →Security & Governance
This layer is about proving what happened, controlling who can do what, and meeting enterprise security expectations without turning governance into a separate project. Traceability, usage visibility, access controls, SSO, ISO 27001, and SOC 2 Type II all support that goal.
