LLMTest: Automated LLM Model Selection and Fallback Tool for Developers
By
Tom Jacquesson
A baker's-dozen of insight crammed into one ring.
Summary
LLMTest is a tool created by maker Tom to help developers and "vibe coders" automatically select the best LLM models for AI-powered features in their applications. It solves the problem of manually testing 300+ models across providers like OpenRouter and Claude. The tool automatically picks better models (faster, cheaper, better quality), sets up fallbacks when LLM providers fail or APIs are overloaded, and integrates through a single API and MCP functions for use with Claude or Codex.

I was constantly trying to figure out which LLM models to choose to power AI features in my products.
LLMTest helps devs and vibe coders automatically: ✅ Pick better models for AI-powered features (faster, cheaper, better, sometimes all 3 combined) ↪️ Automatically add fallbacks when LLM providers fail
