OpenRouter vs OpenAI: Which Should You Use?
FreshRank gives you the flexibility to choose between FreshRank Agent (no API key), OpenAI (direct connection), or OpenRouter (access to 450+ models). This guide will help you understand when to bring your own OpenAI or OpenRouter API key instead of using FreshRank Agent.
Pro Feature: OpenRouter support with 450+ AI models is available in FreshRank AI Pro. FreshRank Agent and OpenAI are available in both the free and Pro versions.
If you want the simplest setup, choose FreshRank Agent. It works without an API key and uses the request allowance included with your plan.
