Artificial Analysis

Artificial Analysis is an independent company that tests AI models and publishes the results for free. Its Intelligence Index gives each language model one score based on a set of hard tests, next to how fast it writes and what a typical task costs. It covers more than 500 models, from ChatGPT and Claude to open models you can run yourself, and the companies that serve them.

It also ranks image, video, speech and music models, using blind votes where people pick the better result without knowing which model made it, and it tests coding agents too. The Model Recommender suggests a model based on whether you care most about quality, speed or price. AI labs, journalists and investors quote its charts all the time, and developers can pull the data through a free API.

The catch is that it's a reference site. You check it before choosing, then do your work elsewhere. It tells you which model scores best on its tests, which isn't always the one that writes best for your business. Use it to shortlist, then try the top two or three on your own prompts.

Ways Artificial Analysis can slot into your week.

1. 1

   Check a new model on launch day

   When a new model is announced, see where it lands on the Intelligence Index before you switch.

2. 2

   Choose the cheapest model that's good enough

   Compare price per task against score to pick a model for a chatbot or automation.

3. 3

   Pick an image or voice model

   Use the image and text-to-speech leaderboards to shortlist tools before you sign up.

Use it alongside LMArena when choosing models, then OpenRouter or the model makers' own apps to try them. It doesn't replace testing on your own work.
