LLM router 1

AI API router optimizing spend by dynamically routing prompts based on difficulty OrcaRouter is an AI API gateway and multi-model LLM router that dynamically routes user prompts to the most cost-effective and appropriate model across OpenAI, Anthropic, Gemini, and over 200 other models. By instantly grading every prompt for difficulty, OrcaRouter directs complex reasoning tasks to frontier models while routing routine requests to cheaper, open-source alternatives. This process allows developers to slash their AI spending by approximately 40% while preserving high-quality results. It features an OpenAI-compatible API, meaning integration requires changing just a single line of code to swap the base URL and API key. OrcaRouter provides transparent 'glass-box' routing by logging the difficulty grade, model selection, and provider for each request with zero token markup, passing the original provider costs directly to the user.
