MCCFR · JAX · GTO LLM COACH

Poker Trainer

A machine-learning challenge based on the realization that large language models are inherently bad at playing games of incomplete information with large possibility spaces. The challenge: build a neural network that can not only play poker as a training opponent but also work together with the LLM to provide insights about game-theory-optimal play. Working toward a multi-day run on a 64× A100 cluster on Vast.ai to distill the solver data into a neural net.

MULTI-TERMINAL · GEMINI LIVE · SPATIAL UI

JOLENE

A multi-terminal UI prototype. When I'm coding with multiple terminals, context switching is crucial, and I find that spatial separation or spatial anchoring of terminals can aid in my context switching between projects. This prototype was an attempt to push that concept further by having 16 terminals at once, maintaining their relative spatial positions to each other rather than a list of most-recent chat conversations, as is the paradigm for many current AI chat experiences. Also used Gemini Live to allow switching between terminals using just voice.
