Access to the Best-in-class AI models with the ability to compare them for the best outputs, AI Browser Copilot, custom AI workflows on the web.
I've just been comparing the latest OpenAI models on Chatplayground - GPT-4.1, o4-mini, o3, etc. There's so many models now (April 2025) - it's great to do side-by-side comparisons to see which one is best for a particular use case. I just love this product - user since August 2024.
