Frequently Asked Questions

Everything you need to know about Leanference.

How does integration work?
Just change your API base URL to point to Leanference instead of OpenAI or Anthropic directly. Add your Leanference API key as a header. Everything else in your code stays exactly the same — same SDK, same parameters, same response format.
Which AI providers does Leanference work with?
Leanference works with all major AI providers including OpenAI (GPT-4, GPT-3.5), Anthropic (Claude), Google (Gemini, PaLM), Cohere, and any OpenAI-compatible API. Our universal SDK means you can use Leanference with your existing codebase without changing providers.
How much can I save?
47% on repeated system prompts, 29% on verbose text, 22% on RAG metadata bloat, plus provider caching savings (90% off on Anthropic, 50% on OpenAI). Total savings: 40-60%.
Is it safe?
Battle-tested across enterprise workloads including adversarial edge cases. Zero false compressions. Quality never drops below your threshold — if optimization would reduce quality, Leanference automatically falls back to full context.
How long does integration take?
Most developers integrate Leanference in under 5 minutes. Install our SDK, add your API key, and wrap your existing calls with our optimization function. We provide one-line integrations for all major frameworks and comprehensive documentation for subscribers.
