Technical Integration

LLM Integrations

Production-grade integration with the model providers that fit your latency, cost, and quality bar.

The plumbing between your product and the model providers — routing, fallback, streaming, and cost controls — so a provider outage or price change doesn't take your AI feature down with it.

What we build

  • Multi-provider routing & fallback
  • Prompt versioning & evaluation
  • Cost & usage monitoring
  • Streaming responses
  • Fine-tuning & prompt engineering

Optimizing tech

The tools we reach for most on llm integrations projects — matched to your scale and budget, not sold as a package.
