Tip: Manifest LLM Router Scores Requests Across 600+ Models in <2ms to Save 40-70% on Agent Costs

GitHub·medium signal

Manifest (6.6K stars) is an open-source LLM router that uses a 23-dimension algorithm to route each agent query to the cheapest model that can handle it, typically saving 40-70% with no quality loss. It can route eligible requests through flat-rate subscriptions (Claude Max, ChatGPT Plus) first, only falling back to pay-per-token when quotas are exhausted. Runs locally with zero data leaving your machine. Particularly useful for agent loops where most subtasks don't need a frontier model.
