New to this? What the scores and labels mean

0 to 100: Our score for one job, like writing or coding, compared with everything else out today. 100 is the best available today. For AI models we build it from public data, such as Arena's blind votes and Epoch AI's independent tests; apps and tools are scored on our own checklist. The same tool can score differently for different jobs, and where two likely ranges overlap, we call it a tie.
Our verdict: Use it: a top choice for most people. Worth trying: good, and worth a go. Depends: good for some people or one kind of job. Wait: too early to tell, or not out for everyone yet. Skip: something else does the job better.
First look: Just released. We say what it is and whether to bother, and give it a score once public results exist.
No score yet: None of the public sources we use covers it yet, or the only evidence is from a source whose numbers we can't use, so we describe it in words instead.
Best buy: Nothing cheaper scores as well for that job.
Best free: The best score for that job that costs nothing, through a free plan or by running on your own computer.
Pay as you go: No monthly plan: you pay for each use, usually through a developer account.
Checked: The day we last confirmed the score and the price against the sources. Prices change often, so check the date.
AI model: The engine underneath, like GPT or Claude. You use it through an app or, if you code, directly.
Open source: Free to download and run on your own computer, so nothing leaves your machine.
