About

Quantslant is an independent publication about artificial intelligence: news, hands-on guides, model comparisons and benchmarks, written for people who actually use these tools at work.

Who runs it

Quantslant is a small independent publication edited and published by Piotr Olszewski. There is no newsroom and no investor behind it: one editor, a test setup, and scripts that fetch prices and service status automatically.

AI tools help with research and first drafts. Choosing topics, running the tests, editing, checking facts and deciding what gets published stay with the editor - and so does the responsibility for every article.

One editor, several languages

I am Piotr Olszewski. I run Quantslant as part of the same independent publishing project as Promptowy and its other language editions. These sites do not have separate national newsrooms. I use AI and automated tools to help prepare, translate and maintain content; I remain responsible for what is published.

Some articles are localized versions of earlier Promptowy articles. A translation is not a new experiment. When reading a test, check its date, method, sources and limitations. Publishing another language version does not make historical results current.

How we work

• Primary sources first. Company announcements, papers, documentation and official price lists. A number we cannot trace back to a source does not get published.
• Tests on real tasks. Models and tools get the same prompts and files, and results are published with the date of the test. The method is described in How we test.
• Dated prices. API prices come from the OpenRouter price list, read automatically every day; subscription prices come from official pricing pages.
• Corrections in the open. When something is wrong, we fix it and say so. See our corrections policy and editorial standards.

What you will find here

• AI news - what changed today, with sources.
• Guides to AI tools - what each tool does, what it costs and when to pick something else.
• Benchmarks and tests - our own measurements.
• API prices by model, model-vs-model comparisons and the AI model ranking.

Shop, ads and independence

Quantslant is run alongside Kinetyra, a shop with vouchers for AI tools. When an article mentions a tool sold there, the article says so. The site also shows Google AdSense ads, and some links to AI tools are partner links, marked as such. None of this decides what we write or how a tool comes out in a test.

Quantslant is published from Warsaw, Poland, and written in English for a global audience. Questions, corrections and tips: contact. The rules for using the site are in the terms of use and the privacy policy.
