Simulate end-to-end multi-turn chat sessions and complete RAG pipelines with embeddings, rerankers, and prompt caching.
In multi-turn chat, previous turns are cached after turn 1 at up to 90% discount on Claude 3.5 Sonnet, DeepSeek, and Gemini.
How to Accurately Estimate LLM API Spend
1. Measure Real Token Ratios
In production, conversational and RAG apps usually have an input-to-output token ratio between 3:1 and 8:1. Long system prompts and retrieved documents drive up input tokens, while responses are usually concise.
2. Exploit Prompt Caching
For repetitive system prompts (e.g., 2,000 token instructions), caching provides up to 90% discounts on Anthropic Claude 3.5 and 50% on OpenAI GPT-4o.
3. Implement Model Cascading
Route 70% of mundane queries (formatting, sentiment, intent detection) to low-cost models like GPT-4o Mini or Gemini 1.5 Flash ($0.15/1M), saving expensive flagship calls for hard reasoning.
