LLM Integration Consulting

Expert consulting for integrating Large Language Models into your products and workflows

Large Language Models are not features. They are infrastructure components that must be integrated carefully — or they become expensive, unreliable, and risky.

H-Studio provides LLM Integration Consulting for companies that want to embed Large Language Models into real products, internal systems, and business workflows — securely, predictably, and at scale.

We focus on architecture, governance, and production readiness — not demos.

What LLM Integration Really Means

Integrating an LLM is not just "calling an API".

Real integration requires:

correct placement in system architecture
control over prompts, context, and outputs
data boundaries and access rules
latency and cost management
fallback and error handling
compliance and auditability

Without this, LLMs:

hallucinate
leak data
break workflows
become unmaintainable

What We Help You Integrate

Product & Platform Use Cases

AI features inside SaaS products
AI copilots and assistants
semantic search & Q&A
AI-powered forms and workflows

Internal & Operational Use Cases

knowledge assistants
document processing
reporting & analysis
customer support automation
engineering & ops copilots

Our LLM Integration Approach

1.

Architecture & Use-Case Validation

We define:

where LLMs add value
where they should not be used
which model types fit the task
latency, cost, and reliability targets

LLMs must fit your system — not the other way around.

2.

Prompt & Context Engineering

We design:

prompt templates
system instructions
guardrails & constraints
context windows & memory strategies

This ensures:

predictable outputs
domain consistency
reduced hallucinations
3.

Data & Knowledge Integration

We connect LLMs to:

databases
documents
APIs
internal systems

Often via:

RAG architectures
controlled retrieval layers
role-based access
4.

Governance, Safety & Compliance

Enterprise-ready LLM integration includes:

data isolation
access control
logging & traceability
usage limits
fallback logic
GDPR-aware data handling
5.

Production Readiness

We help you with:

deployment strategies
monitoring & evaluation
cost optimization
performance tuning
vendor abstraction (no lock-in)

Typical Problems We Solve

"The AI gives random answers"
"We don't know what data the model sees"
"Costs are exploding"
"Latency is too high"
"Legal / compliance blocked the rollout"
"We can't maintain prompts at scale"

Who This Service Is For

SaaS companies adding AI features
enterprises integrating AI into workflows
teams moving beyond prototypes
regulated industries
CTOs and product leaders

FAQ

What's the difference between LLM integration and just using an API?

Using an API is making a call. LLM integration means embedding LLMs as system components with proper architecture, control, governance, and production readiness. Integration includes prompt engineering, context management, data boundaries, fallback logic, monitoring, and compliance — not just API calls.

How do you prevent LLMs from hallucinating?

We use prompt engineering, guardrails, context constraints, RAG architectures for grounding, confidence thresholds, and fallback logic. We also design system instructions that enforce factual accuracy and domain consistency. Hallucination prevention is built into the integration architecture.

Can you integrate LLMs with our existing systems?

Yes — we integrate LLMs with databases, APIs, CRM/ERP systems, document stores, knowledge bases, and internal services. We use RAG architectures, controlled retrieval, and role-based access to connect LLMs to your existing infrastructure securely.

How do you handle GDPR and data privacy?

We implement data isolation, access control, logging, data minimization, and GDPR-aware data handling. We use EU-based infrastructure where required, ensure data boundaries are respected, and provide audit trails. All LLM integrations are designed with compliance from the start.

How long does LLM integration take?

A basic LLM integration (architecture + prompt engineering + basic governance) typically takes 4-8 weeks. Complex integrations with multiple systems, extensive RAG architectures, and enterprise governance can take 12-20 weeks. We start with an architecture review to define scope and timeline.

Can you help us avoid vendor lock-in?

Yes — we design vendor abstraction layers, use standard interfaces, and implement fallback strategies that allow switching between LLM providers (OpenAI, Anthropic, local models) without rewriting your integration. This gives you flexibility and cost control.

We provide LLM integration consulting services for businesses across Germany. Our Berlin-based team specializes in Large Language Model integration, LLM architecture, prompt engineering, RAG systems, enterprise AI integration, and production-ready LLM implementations.
