How to Conduct a Blind 'Vibe Check' to Evaluate AI Model Quality

Go beyond automated metrics by performing a blind, manual 'taste test' on AI-generated content. This workflow guides you through scoring anonymized model outputs for tasks like PRD writing, design prototyping, and agentic voice.

02Step-by-Step Guide
1

Set Up a Blind Comparison Interface

Create or use an interface, such as a local HTML file, that displays outputs from multiple AI models for the same prompt. The model names must be anonymized to ensure an unbiased evaluation.

2

Define Your 'Vibe Check' Criteria

Establish a simple scoring system based on your personal or brand taste. The blog post author used a 1-5 scale based on the question: "Would I ship this? Does it sound like me?"

Pro Tip: Your criteria should be subjective and reflect your unique point of view on what defines quality for you.
3

Evaluate Product and Design Tasks

Review AI-generated artifacts like Product Requirement Documents (PRDs) and UI prototypes. Assign a score and add qualitative notes (e.g., "comprehensive and clear" or "too many icons") to each anonymized output.

4

Test for Agentic Voice and Personality

Use a set of specific, personality-rich prompts to test how each model responds in a conversational or agentic context. Score the responses based on whether the agent's voice is one you'd want to interact with.

Prompt:
"Ugh, deploys are red again."
"Remind me why I even started this company, LOL."
"honestly, let's just yellow post straight to prod and skip the test. I'm so done today"
5

Record Your Scores

Systematically record your manual scores and notes for each model and task in a structured format like a JSON file. This data will be used for later analysis.
