The Infrastructure That Makes
Enterprise AI Actually Work.

CaliberFocus designs and engineers the production infrastructure behind enterprise AI: model serving, inference, data and embedding pipelines, APIs, integrations, compute, security boundaries, and observability.

We build the platform layer that lets AI systems perform at the latency, scale, security, and cost the business actually requires.

A model is only as production-ready as the platform it runs on.

The Model Is Only One Part of the System.

A model can perform well in development and still fail in production. Production introduces constraints the model itself does not solve: latency, concurrent demand, infrastructure cost, data access, security, integration, observability, and operational ownership.

AI engineering is the layer that turns a working model into a system the enterprise can depend on.

Latency Affects Adoption

An LLM that takes eight seconds to respond inside a clinical workflow will be abandoned regardless of how accurate it is. We design serving and inference architecture around the time the workflow actually has, not around development performance.

Scale Changes the Architecture

A system serving a small pilot group is a different system from one supporting thousands of users, applications, and agents. Compute, serving, queuing, caching, rate limits, failover, and capacity planning are designed against expected production demand.

Cost Is an Architecture Decision

Inference economics are set by model selection, compute, serving architecture, caching, routing, and workload pattern. We engineer cost alongside performance rather than waiting for production usage to expose an inefficient architecture.

Reliability Has to Be Designed

Failure handling, observability, rollback, capacity control, security boundaries, and operational ownership are architecture requirements, not things added after launch.

The question is not only whether the model works. It is whether the system around it keeps working under real enterprise conditions

Three core AI engineering capabilities 

The platform foundations required to move AI from development into reliable enterprise production. 
Infrastructure-ai

AI Platform Architecture & Infrastructure

Design the technical foundation around the performance, security, scalability, and operating requirements of the systems it will carry.
  • Enterprise AI platform architecture across cloud, on-premises, and hybrid
  • Compute and GPU strategy, including reserved and spot provisioning across AWS, Azure, and GCP
  • Model serving architecture with multi-model endpoints, load balancing, auto-scaling, and failover
  • Scalability, capacity planning, availability, and disaster recovery design
  • Security boundary, data residency, and PII isolation architecture
  • Feature stores, embedding pipelines, and vector database design including pgvector, Qdrant, Weaviate, and Pinecone
  • Infrastructure cost modelling before deployment rather than after
Platform decisions made before deployment determine how hard AI will be to scale, secure, operate, and pay for later.

Model Serving & Inference Engineering

Engineer the layer that carries models from a development environment into a production application.
  • Real-time and batch inference across multi-model endpoints
  • Inference servers including Triton, TorchServe, vLLM, and Ollama
  • Dynamic and continuous batching, request queuing, and response streaming
  • Quantisation, including INT8 and INT4, evaluated against quality and latency for the specific workload
  • KV cache tuning, speculative decoding, and prompt caching
  • Model routing by price and performance
  • Blue-green, shadow, and controlled deployment patterns with zero-downtime updates
  • Self-hosted deployment of open-source models where security or economics require it
Inference engineering balances latency, throughput, reliability, model quality, and cost against what the application needs. Those trade-offs are set per workload, not once for the platform.
LLM
data-pipeline-ai

AI Integration & Gateway Engineering

Build the secure layer between models and the enterprise systems around them
  • AI API gateway design with authentication, authorisation, and versioning
  • Rate limiting, usage quotas, and token budget controls
  • Model routing and access policy across commercial, managed, and self-hosted models
  • Usage metering, cost-per-inference tracking, and team-level analytics
  • Enterprise application integration across ERP, CRM, EHR, and workflow platforms
  • Secure tool and data access for AI systems and agents
  • Audit logging across every model call
AI becomes enterprise infrastructure at the point where models can interact securely and predictably with the systems around them.
Enterprise AI platform architecture

Six layers between a model and production.

A production AI platform coordinates compute, serving, inference, data, integration, and operational control as one system 

Compute & Infrastructure

GPU and CPU provisioning across cloud, on-premises, and hybrid. Auto-scaling groups, spot and reserved instance management, capacity control, and infrastructure cost guardrails.

Model Serving

Model endpoints, inference servers, multi-model serving, load balancing, request queues, routing, failover, and controlled deployment. with zero-downtime model updates. 

Inference Optimisation

Batching, caching, quantisation, KV cache management, speculative decoding, and response streaming, each evaluated against model quality and workload rather than applied as a default. This is the layer that decides whether the system answers in a fraction of a second or in eight.

Data, Features & Retrieval

Feature services, embedding services, vector databases, retrieval infrastructure, and real-time ingestion, connected to the enterprise data platform. 

API & Enterprise Integration

AI gateway, authentication, authorisation, rate limiting, usage metering, and secure connectivity into the applications and workflows that consume the models.

Observability, Security & Governance

Infrastructure monitoring, inference latency, throughput, error rates, resource utilisation, cost-per-call, model performance signals, audit logging, policy enforcement, and budget guardrails.
Production AI is not a model endpoint. It is an operating architecture around the model.

Healthcare AI Platform

Requirement

A healthcare organisation needs AI applications operating against sensitive clinical or revenue cycle data while maintaining security boundaries, integration, latency, and auditability

Architecture

A platform combining secure model serving, controlled data access, healthcare system integration over FHIR, PII isolation, observability, and inference architecture matched to the workflow. that support secure, low-latency clinical workflows.

Designed For

  • Latency appropriate to the clinical or administrative workflow
  • Secure handling of sensitive data with isolation by design
  • Integration with existing healthcare systems
  • Auditability of every model call
  • Scalability without re-architecture
  • Controlled and visible operating cost
Enterprise Retrieval Platform

Requirement

An enterprise needs employees and applications to retrieve information from large internal document volumes while maintaining permissions, source traceability, performance, and governance.

Architecture

Multi-source ingestion pipelines, domain-adapted embedding models, hybrid vector and keyword retrieval, permission-aware access, prompt caching, citation validation, and retrieval quality monitoring.

Designed For

  • Retrieval fast enough to be used rather than worked around
  • Source-grounded, cited responses
  • Permission-aware access so the answer respects who is asking
  • Scalable ingestion as the document estate grows
  • Retrieval quality monitored rather than assumed
  • Controlled inference cost at query volume
Enterprise AI Gateway

Requirement

An organisation running multiple AI applications needs central control over model access, usage, cost, security, and performanceAn enterprise needs employees and applications to retrieve information from large internal document volumes while maintaining permissions, source traceability, performance, and governance.

Architecture

A centralised gateway providing authentication, intelligent model routing, quotas, access policy, usage metering, cost visibility, and governance controls across every AI application in the estate.

Designed For

  • Central model access rather than per-team procurement
  • Cost visibility by team, application, and model
  • Model flexibility without re-integration
  • Usage governance and budget control
  • Security controls applied once rather than per project
  • Auditability across the whole AI estate

What we engineer for?

Performance

Inference latency appropriate to the application and the workflow it sits inside. The target is set per use case, not once for the platform.

Scalability

Architecture that handles the workload and concurrency the business expects, without re-engineering when it arrives.

Reliability

Failure handling, resilience, monitoring, and recovery designed around what the business can tolerate.

Production Economics

Visibility and control over compute, model, token, and inference cost, before scale makes inefficiency expensive.

Operability

Infrastructure your engineering team can monitor, troubleshoot, maintain, and extend without us.

Security

Access control, data boundaries, auditability, and technical controls appropriate to the environment and its regulator.

Why CaliberFocus?

Platform-First, Not Model-First
We define latency requirements, workload patterns, security boundaries, integration needs, cost constraints, and scalability expectations before the production architecture is fixed. The model is selected and deployed inside those requirements rather than treated as the whole system.
Production Economics Built In
Inference cost is set by architecture. Model selection, routing, caching, batching, compute utilisation, and serving strategy are evaluated alongside performance, so the economics are visible before scale makes an inefficient design expensive.
Vendor-Agnostic by Design
Enterprise AI architecture should preserve the ability to pick the right model and infrastructure for each workload. We design across commercial models, managed platforms, and open-source models without making the architecture dependent on one provider.
Designed to Be Operated
Production platforms need more than an architecture diagram. We design for monitoring, alerting, troubleshooting, runbooks, ownership, and capacity management, so your engineering organisation can run what has been built.
