    Everyone's talking about how easy it is to build AI agents. The hard part nobody talks about? Evaluation. In the LLM era, you don't need data to build. You just prompt. But you still need data to know if what you built actually works. The current process: hand your agent to

    GODEL is available on hugging face. Looking for a large open-source pre-trained language model for dialog? GODEL leverages grounded pretraining designed to better support finetuning phases that require information external to the current conversation (e.g. database or document).

    Congrats Dr. Weiyan Shi! Weiyan is my first PhD student that graduated from Columbia. It was a pity that we couldn't do this type of celebration last year with my two Davis PhD graduates.

    This is why I encourage cleaning existing datasets and creating better new datasets. After all, we are solving problems not building models to fit data sets. We cleaned MultiWOZ recently and will publish a tech report along with the cleaned data soon.

    Jaime was not only a great researcher but a great department chair. I still remember him paying a semester of my tuition when I left one of my advisors in the mid of my PhD. He is a kind person who believes in students. Jaime will be remembered.
