2. Purpose
Qué IA uso is a free informational website that compares artificial intelligence models and tools based on public data: independent tests, rankings, official prices and news. Access is free and requires no registration. Using the site means accepting this legal notice; if you do not agree, please do not use it.
3. Disclaimer of warranties and liability
The information is provided for informational purposes only. Scores, rankings, prices and features come from public third-party sources (Artificial Analysis, LMArena, Hugging Face, OpenRouter, official pricing pages, among others) and are reviewed frequently, but they may contain errors, be incomplete or have changed since the last update. Euro prices calculated from dollars are approximate (ECB reference exchange rate).
Nothing published here constitutes professional advice (technical, legal, financial or purchasing). Before signing up for a service or making a decision, check the current terms and prices on each provider's official website.
The owner does not guarantee the continuous availability of the site or the absence of errors, and is not liable for any damage that may arise from the use of the published information, except where the law does not allow such liability to be excluded.
