What is PickLLM?
PickLLM lets you compare OpenAI model outputs side by side using your prompt. Supports GPT-4.1, GPT-4o, o4-mini, o1, and more. Uses your API key via a minimal proxy (not storing key). Customize models and settings. Built for quick, no-setup testing.
Problem
Users previously needed to manually compare outputs from different OpenAI models, which is time-consuming and inefficient, requiring switching between platforms or custom scripts.
Solution
A comparison tool enabling users to input a prompt once and view outputs from multiple OpenAI models (e.g., GPT-4o, GPT-4.1) side by side, using their own API key via a secure minimal proxy.
Customers
Developers, data scientists, AI researchers, and product managers working on AI-driven applications requiring rapid model testing and optimization.
Unique Features
Real-time side-by-side comparison without API key storage, supports customization of models/settings, and instant no-setup testing.
User Comments
Saves hours of manual testing
Intuitive interface for model selection
Secure API key handling
Helps identify cost-performance tradeoffs
Essential for prompt engineering
