About each tool

Folkbench

Folkbench probes AI API relays per model and publishes success rate, response time and listed price with source-typed fields and per-run reports. It also ships Folkbench Switch, an open-source desktop app that writes a chosen Base URL and key into Claude Code, Codex or Gemini CLI after a diff preview.

GPT-4

GPT-4 represents OpenAI's legendary reasoning milestone model. It was the first modern model to demonstrate high-level academic intelligence, passing bar exams, advanced placement science tests, and complex logic puzzles with elite scores.While succeeded by faster models, its architectural solidity, logical precision,…
