Platform — capability areas
The control system around the model.
Models are components. Tresonant builds everything a regulated organisation needs around them: specification, evaluation, runtime constraint and evidence. Three capability areas, one architecture.
01 / AI reliability engineering
Deterministic pipelines around probabilistic parts.
A language model is not an architecture. We wrap probabilistic components in engineering that makes the whole system's behaviour specified, bounded and repeatable.
Systems whose behaviour is written down before it is shipped.
- Typed input/output contracts — every model call has a schema; malformed output is a handled failure, not a surprise downstream.
- Constrained generation — structured decoding, allow-listed actions and bounded tool use, so the model can only do what the specification permits.
- Deterministic orchestration — control flow lives in reviewable code, with pinned model and prompt versions and reproducible configuration.
- Failure budgets and fallbacks — defined behaviour for timeouts, low-confidence outputs and rejected responses: retry, degrade or escalate to a human.
- Change control — prompts, policies and models are versioned artefacts; every change is diffable, reviewed and traceable to a release.
02 / Evaluation & guardrails
Prove the boundary. Then enforce it.
Evaluation demonstrates that the system meets its specification; guardrails hold that specification against live traffic. We build both from the same source: your policies and your edge cases.
Test suites derived from policy, not vibes.
- Policy-derived assertions — each clause of your operating policy becomes testable checks against real and synthetic cases.
- Regression gates — every prompt, model or policy change re-runs the full suite; regressions block release by default.
- Adversarial suites — prompt-injection, data-exfiltration and jailbreak batteries maintained as living test sets.
- Calibrated grading — automated grading is itself audited against human judgement on sampled cases, with disagreement tracked.
Runtime enforcement of the same specification.
- Input screening — malformed, out-of-scope or adversarial inputs are rejected or quarantined before any model call.
- Output verification — schema validation, policy filters and consistency checks between model output and source data.
- Bounded tool use — models act only through allow-listed, permissioned tools with per-action audit records.
- Mandatory escalation — low-confidence or policy-adjacent outputs route to a named human owner; the system never quietly guesses.
03 / Deployment for regulated environments
Shipped with the evidence attached.
In a regulated organisation, deployment is not the end of engineering — it is a submission of evidence. We build systems whose controls can be inspected, and we write the documentation ourselves.
Designed to survive an audit, not just a demo.
- Decision-level audit trails — inputs, versions, guardrail verdicts and human sign-offs recorded for every output, with a documented log schema.
- Data-residency options — UK/EU deployment patterns, client-cloud and on-infrastructure delivery where obligations require it.
- Human-in-the-loop checkpoints — approval steps placed where accountability actually sits in your organisation, not bolted on afterwards.
- Access control & segregation — least-privilege service boundaries; no shared credentials between environments.
- Documentation packs — system descriptions, control mappings, evaluation reports and residual-risk statements written for risk committees and auditors.
What we will not build.
- No unaccountable autonomy — we do not ship systems that make regulated decisions without a named human owner and an escalation path.
- No undisclosed components — every model, vendor and sub-processor in the chain is disclosed to you and approved by you.
- No training on your data without instruction — client data is used only as your written instructions permit.
- No borrowed credibility — we claim no certification we do not hold and name no client we do not have.
