About The Prompt Bench
A free, ad-free, sourced site about prompting AI, running models locally, and tracking what's coming next — published by a small German software studio.

Site mission
Make prompting clearer and the model landscape legible
The Prompt Bench exists to make the AI you actually use clearer: what prompts work, which local models are usable today, how the popular ones compare, and what's rumored to ship next.
The site is free to read, has no ads, and is built to be genuinely useful in a working session. Every page should leave you with a usable technique, a runnable command, a comparison table you can act on, or a sourced read of where the field is heading.
We do not generate listicles, we do not pretend to predict the future, and we do not republish leaks without dates and sources. Anything dated says so, in writing, near the top.
Who we are
Who We Are
The Prompt Bench is published by ai51 UG, a small software studio in northern Germany. Our team includes two physics PhDs, and most of our day-to-day is building software that helps people learn.
We started prompting models seriously around the same time everyone else did, and we kept noticing the same gap: most prompting content is generic, most local-model content goes stale in weeks, and most rumor coverage is shareable without being trustworthy.
This site is our attempt to fix that for ourselves first — documented carefully enough that we'd send it to a colleague — and then leave it open for anyone to read.

The Prompt Bench Editorial
Pieces are written or edited by the ai51 team. We sign articles under one editorial banner because the bench is the brand, not the byline. Where a piece reflects strong personal opinion or first-hand testing, the author is named inline.
