The problem with @perplexity_ai:
You ask it question like 'What is the best framework for x' and you get nice report with pros and cons which is really helpful (imho), but there is no link to any of the frameworks. Now I have to go to google and search for the framework I choose.
I wonder when o1-preview was available for the first time inside OpenAI. Must be something like early 2024 because the leak was November 2023. Nice from Sam to let everyone catch up.
