The Opportunity

Problem

Freelancers building custom AI solutions struggle to charge fair prices as clients demand rates comparable to free LLMs, severely eroding profit margins.

Solution

EdgeBench lets freelancers input client prompts, runs them on free LLMs like GPT-4o-mini, simulates custom AI improvements, and generates shareable comparison reports. Clients see quantifiable gaps in accuracy, speed, and cost. This demo tool closes deals by proving custom value before building.
