LLM Integration

Frontier models, wired into systems your business already runs.

The model is not the integration. The integration is auth, streaming, cost controls, eval gates, provider routing, fallbacks, regional residency, and a feedback loop into the next prompt change. We build the integration.

LLM integration is the work between “the API responds” and “the feature ships to a regulated production environment.” It includes auth (SSO, per-tenant rate limits), streaming (SSE/WebSocket plumbing through your stack), cost controls (caching, prompt size budgets, model fallback), eval gates (regression on prompt or model change), and provider routing (per-task model choice, regional pinning, failover).

What you get

An integration platform, not a one-off feature.

  • A production LLM integration

    Auth, streaming, cost controls, retry logic, fallback routing — running in your environment, owned by your team after handover.

  • Eval gates in CI

    Prompt and model changes can't deploy without passing your eval suite. Drift is caught before users feel it.

  • Cost engineering

    Caching strategies (semantic + standard), prompt size budgets, model selection per task. Most engagements cut spend 30–50% versus the naive integration.

  • Provider portability

    Switch models without rewriting application code. Per-task routing across OpenAI, Anthropic, Bedrock, Vertex, Azure, OpenRouter, vLLM.

  • Compliance posture

    Region pinning (EU, US, regulated jurisdictions), audit logging, no-retention agreements. Designed around the audit, not retrofitted.

What we ship

The plumbing, in detail.

Provider clients
Thin, typed wrappers around OpenAI, Anthropic, Bedrock, Vertex, Azure OpenAI, OpenRouter, and self-hosted (vLLM, TGI).
Routing
Per-task model selection, fallbacks, region pinning, retry-with-degrade. Configured in code, observable in traces.
Caching
Semantic cache (vector-based) for high-volume reads. Standard request cache where keys allow.
Cost telemetry
Per-tenant, per-feature, per-model. Surfaced in your existing observability stack (Datadog, Honeycomb, Grafana).
Eval
Prompt eval suite + LLM-as-judge for quality drift. CI-integrated. Blocks deploy on regression.
Compliance plumbing
Region pinning, request/response logging with PII redaction, no-train guarantees, model attestation tracking.

Proof
A global asset manager wanted research-assistant features inside their existing portfolio platform. We integrated three model providers behind a routing layer, added a semantic cache that cut spend ~40%, and shipped eval gates that caught two prompt regressions before they reached production.

Frequently asked

What buyers actually ask

Can you deploy on-premise or in our VPC?
Yes. We've shipped on AWS Bedrock private endpoints, Azure OpenAI in customer tenants, GCP Vertex with VPC-SC, and self-hosted vLLM/TGI in customer Kubernetes. Choice depends on residency, latency, and cost constraints.
What does an LLM feature actually cost?
Depends on tokens per call × calls per day × your model mix. Most enterprise features land between $0.005 and $0.10 per call after we apply caching and prompt-size discipline. We give you a forecast on day one of the engagement.
SOC 2, HIPAA, ISO 27001 — can you work within these?
Yes. The integration is designed around the compliance constraint, not retrofitted. We've shipped under SOC 2 Type II audits and HIPAA BAAs.
How do you handle prompt regressions when you swap models?
Eval suite + golden set. Every prompt and every model change runs against the suite in CI. Drift is visible before deploy.
