Gen AI services

Generative AI, engineered for production

LLM integration, retrieval, agents and multimodal systems — built with the guardrails, observability and evals that keep them working after the launch day.

What we build

Six capability tiers

Organised by architectural layer, not by sales slogan. Every tier has a defined set of deliverables.

Foundation

LLM integration & evaluation

Model selection, prompt engineering, context-window strategy, and eval harnesses. Model-agnostic — we pick based on cost, latency, licensing and benchmark fit for your task.

Typical deliverables

  • Model shortlist with cost / latency / eval trade-off brief
  • Production prompt library with version history
  • Regression eval suite in CI
  • Secrets + key rotation policy
Knowledge

Retrieval-Augmented Generation (RAG)

Turn your documents, databases and ticket history into grounded, citable answers. Hybrid dense + sparse retrieval, re-ranking, and provenance on every response.

Typical deliverables

  • Ingestion pipeline with incremental re-index
  • Hybrid vector + keyword retrieval
  • Reranking + citation layer
  • Hallucination & groundedness metrics
Autonomy

Agents & multi-step workflows

Agentic systems that plan, call tools, handle errors and hand off to humans. Budget-bounded, observable, and rollback-safe — built for customer-facing throughput, not leaderboard demos.

Typical deliverables

  • Tool & function schemas with JSON-schema validation
  • Step-level tracing and replay
  • Budget & max-steps guardrails
  • Human-in-the-loop escalation path
Multimodal

Vision, speech & document AI

OCR, invoice & contract parsing, product-image understanding, call transcription, video summarisation. One pipeline across text, image, audio and video.

Typical deliverables

  • Document extraction with confidence scores
  • Vision classification & grounding
  • Realtime transcription (Whisper-class)
  • Structured-output validation
Developer AI

Internal copilots & code tooling

Private copilots that understand your codebase, docs and runbooks. IDE plugins, PR reviewers, and bespoke chat surfaces — trained and retrieved against your SSOT, not the public web.

Typical deliverables

  • Repo-grounded retrieval index
  • IDE & PR integrations
  • Role-scoped access controls
  • Usage & acceptance-rate telemetry
Predictive

Forecasting & ML models

Churn, demand, fraud, recommendation, propensity. Trained on your data, evaluated against your business metric, retrained on a schedule you can audit.

Typical deliverables

  • Feature store & leakage review
  • Champion / challenger training loop
  • Model card & bias audit
  • Drift monitoring & auto-retrain

Engagement

From brief to operating AI

A structured path that de-risks AI adoption at every stage.

  1. Stage 015–10 days

    Discovery & scoping

    Workflow audit, data review, and a one-page scope with a measurable eval target. Engineering sign-off before any code ships.

  2. Stage 022 weeks

    Working prototype

    End-to-end prototype on real data. Proves out the riskiest assumption first so the business case is decidable in a fortnight.

  3. Stage 034–8 weeks

    Production engineering

    Guardrails, rate limits, caching, fallbacks, observability, security review. Everything between a demo and an SLA.

  4. Stage 04Ongoing

    Operate & improve

    Weekly eval review, prompt / retrieval / model iteration, drift and cost monitoring. Change tracked against the eval score.

Discovery

Book a Gen AI discovery

Two-week, fixed-scope discovery. You leave with a scoped architecture, an eval target, and a costed build plan — whether or not you engage Cord4 for the build.
