KI-Beratung: LLM API Integration
Large language models like GPT-4, Claude, or Gemini only deliver their value when connected to your systems. We integrate LLM APIs cleanly into your existing software landscape – with robust error handling, caching strategies, and clear cost limits, so your product runs reliably and API consumption stays manageable.
Challenges you'll recognise
- Your LLM prototype works in testing but isn't production-ready and reliable yet.
- API costs scale uncontrollably with usage and are becoming a real problem.
- You're unsure which data is allowed to pass through external API services and which isn't.
Stable API Connection
An LLM API integration that works in the prototype but fails under load or generates unexpectedly high costs isn't a success. We build production-ready integrations with robust error handling, rate limit management, retry logic, and monitoring. Your system runs reliably – even when the API side has temporary issues.
Keeping Costs Under Control
API costs can escalate quickly when caching, prompt optimization, and usage limits aren't considered from the start. We implement cost limits, caching layers, and efficient prompt designs so your LLM usage remains scalable and economical.
Model Selection and Fallbacks
Not every task needs the most powerful model. We help you choose the right model for each use case – and build fallback logic that switches to an alternative if one model is unavailable. Reliability and cost-consciousness go hand in hand.
Privacy and Compliance
Which data is allowed to pass through external API services, and which isn't? We clarify this before integration and build appropriate data masking, anonymization, or on-premise alternatives. Compliance is part of the architecture decision, not an afterthought.
Good to know
Production-Ready
Error handling, retry logic, rate limit management, and monitoring – we build LLM integrations that work reliably under real load conditions.
Cost Control
Caching, prompt optimization, and model routing keep API costs manageable. Clear limits and alerts prevent unpleasant billing surprises.
Privacy-Compliant
Data masking, anonymization, and on-premise alternatives ensure compliance – you decide which data flows through external APIs.
