Prism routes simple queries to Gemini Flash or Claude Haiku, and complex queries to Claude Sonnet or Opus. Classification is rule-based and runs per request. Your code doesn't change — just swap the base URL.
Prism is an OpenAI-compatible HTTP API proxy at api.prism.ssimplifi.com/v1. It classifies each request as simple, code, reasoning, or complex, then routes it to the cheapest model capable of handling it — across Anthropic Claude (Opus, Sonnet, Haiku), OpenAI (GPT-4o, GPT-4o-mini), and Google Gemini (2.5 Pro, 2.5 Flash). Integration is a one-line URL change; the request and response formats are identical to the OpenAI Chat Completions API. Three-layer response caching, session memory, and automatic provider failover are built in.
Prism classifies your query and routes it to the cheapest model that can handle it well.

Most production AI traffic is repeat traffic. Prism stacks three caching layers and skips the model when the answer already exists.
Byte-identical request → previous response. Sub-10ms, zero model cost. Catches the 5–15% of traffic that repeats verbatim.
Same meaning, different words. Cosine-similarity match against your prior responses. Catches the 30–60% of near-duplicates that exact misses.
Anthropic prompt caching + OpenAI cached input. 60–90% off the input tokens of stable system prompts, even on cache misses.
Stacked, these layers typically cut total AI spend in half on top of routing savings. Read the math →
