A quick suggestions for newbies, just like myself. i would like to mention that openAi is the best chat model to use as it well integrated into n8n relative to other models, but for other reasons such as testing out if ai automation is your "thing", whatsoever. you can use other models such as gemimi model 2.0 flash thinking etc. via ai agents or 'basic llm chain" you can also twerk your way around other functionalities such as using structured output parser to process your output as json etc. Good luck to everyone!!!
