Claude finally integrated web search into its results...

But with LangChain & LangGraph, you can build a chatbot that integrates web search into ANY model you like!

You'll learn how to do that (and much more) in my new AI course...

I asked GPT-4o to write a New Yorker-style caption for this real New Yorker cartoon.

Here was my favorite:

"Just wait until the Series A investors hear we’ve gone fully remote."

And the real caption:

"The wind in your hair, the scent of nature all around—this is what data entry was meant to be."

🏆 Which LLM is best?

There's no one model that is superior across all use cases. Rather, each model has its strengths and weaknesses, plus costs vary widely!

Here’s the best model for each task according to my favorite AI newsletter, The Neuron 👇
