LLM Integration

You already have a product, a codebase and users. Integration work is about fitting model capability into that reality — behind feature flags, with fallbacks, cost ceilings and a way to roll back.

Capabilities

What this includes

Provider abstraction

One interface across OpenAI, Anthropic, Google and open-weight models so you are never locked to a vendor or a price change.

Streaming interfaces

Token streaming, partial rendering and cancellation that make latency feel like responsiveness.

Prompt management

Versioned, reviewable prompts stored as configuration rather than buried in code.

Cost controls

Per-tenant budgets, rate limits, caching and automatic downgrade paths under load.

Fallback chains

Automatic failover between providers when one degrades or rate-limits.

Structured outputs

Schema-validated responses your existing code can consume safely.

Outcomes

What you end up with

  • Model capability shipped behind feature flags
  • No vendor lock-in
  • Predictable cost per request
  • Rollback in minutes, not days

Questions

Frequently asked

Which provider should we use?

Usually more than one. We benchmark candidates on your actual workload and keep a fallback configured — provider performance and pricing move constantly.

Can you work inside our existing codebase?

Yes. Most integration work happens in your repository, in your style, reviewed by your engineers.
