PageIndex is a vectorless RAG framework that uses LLMs for retrieval. Developers often ask: Which LLM works best with PageIndex? Today, we're launching the PageIndex Benchmark, starting with financial QA and comparing leading LLMs on accuracy and cost. Congratulations to @MiniMax_AI on M3.1 Flash and @GeminiApp on Gemini 4 Argon for achieving impressive accuracy–cost trade-offs!
