The labs
Each lab takes one category of AI tool and puts it through its own fixed, public benchmark, its own prompts, its own leaderboard. One is live now; more are in the works.
AI Image Generation Lab
Ten text-to-image tools, nine identical prompts, first output kept and scored on the same rubric. Every image published, the wins and the failures.

Most best-of lists rank tools the author never opened, using stock screenshots and vibes. We do the opposite, and the method is deliberately strict so the scores mean something.
Within each lab, every tool gets the identical set of prompts, pasted verbatim. We use default settings and keep the very first output, with no re-rolls and no picking the best of a batch. The moment you curate results, a benchmark becomes an opinion, so we don't.
We sell nothing on this list, which means there's no commercial reason to rank one tool over another. The scores are the scores.
One fixed prompt set per lab
Each lab uses its own set of identical prompts, given to every tool verbatim and designed to expose specific failure modes. The exact prompts live on each lab.
First output kept
Default settings, no re-rolls, no cherry-picking. The first result the tool returns is the one that gets scored.
Scored on a fixed rubric
Every result is scored on the same axes at full resolution, where artefacts actually show, then averaged. Each lab publishes its exact rubric.
No sponsorship, nothing for sale
We don't sell the tools we rank, so placement can't be bought. Outbound links go to each tool's official site, and none of them are affiliate links.

Quick answers
What is Pipgen?
Pipgen is an AI tool testing lab. We take one category of AI tool at a time, put every tool through the same fixed, public benchmark, and publish the real results, the wins and the failures. Our first lab covers AI image generators; more are on the way, each with its own prompts and leaderboard.
How do you test and score tools?
Within each lab, every tool gets an identical set of prompts on default settings, and we keep the very first output with no re-rolls or cherry-picking. Each result is scored on the same fixed rubric at full resolution, then averaged into an overall score. Each lab publishes its exact prompts and rubric.
Why should I trust these rankings?
Because you can see the work. We publish every raw output behind every score, so you can judge for yourself rather than taking our word for it. We also sell none of the tools we rank, so placement can't be bought and the scores can't be influenced by a vendor.
Do you make money from this?
Outbound links go to each tool's official site and are not affiliate links. Nothing on any leaderboard is sponsored or paid for. The scores are the scores.
