The Stanford OVAL
Knowledge Assistant
We build LLM-Augmented Cognition Systems (LLM-CSys) that combine the expressive language skills of LLMs with the interpretability and reliability of software systems. We connect LLMs with databases, compilers, and executive functions to create assistants that are more trustworthy and helpful.
ABOUT OUR WORK
Standalone LLMs are like the speech centers in our brains. They
rely on the prefrontal cortex for executive functions (attention, long-term planning) to communicate effectively.
- Professor Monica Lam
RECENT TALK
"Controlling and Grounding Large Language Models for Conversational Assistants"
Generative AI and Foundation Models Workshop, Stanford Computer Forum, April 12, 2023
We invite students, researchers, and corporations to join us to advance the state of the art in conversational agents research and to apply the technology to real-world use cases.
