How it works

Four routes.
One proxy endpoint.

ROUTE A
Semantic Cache
Stores LLM responses and returns cached answers for semantically similar questions — even if the wording differs.
↓ up to 100% cost on repeated queries
ROUTE B
Prompt Compression
LLMLingua 2 compresses verbose prompts by up to 50% before sending, reducing input token cost immediately.
↓ up to 50% on input tokens
ROUTE C
Model Router
Analyses each request and routes simple tasks to cheaper models (gpt-4o-mini, Gemini Flash) in under 1ms.
↓ up to 90% per routed request
ROUTE D
Context Pruning
Summarises old conversation turns when context exceeds 8K tokens, preventing runaway costs in long agent threads.
↓ up to 60% on long conversations
Integration

Two env vars.
Everything else is automatic.

Works with OpenAI SDK, LangChain, AutoGen, CrewAI, Vercel AI SDK, and any tool with a custom base URL setting.
