LLM Integration

Production LLM features inside your product—prompting, routing, caching, and cost/latency controls.

LLM Integration puts model calls behind clean application interfaces. We design prompts and structured outputs, add caching and fallback models where useful, and instrument cost and latency so AI features remain operable as usage grows.

Who it’s for

  • Product engineering teams adding AI features
  • Platforms needing multi-model routing
  • Teams replacing prototype notebooks with production paths

Problems we address

  • Model calls are scattered through the codebase
  • Costs and latency are invisible until the bill arrives
  • Prompt changes have no review or rollback story

Expected outcomes

  • Centralized LLM client with structured interfaces
  • Observability for tokens, latency, and errors
  • Prompt versioning and safe rollout patterns
