The effect of psychedelics is often described as an increase in fluidity – of being, in some non-specific sense, more free to wander out of usual habit patterns. This essay presents an analogy to a feature of LLMs, namely the temperature parameter, that allows a precise characterisation of this increased fluidity. It begins with a semi-technical description of how this parameter affects the operation of an LLM, and then draws a parallel to how psychedelics affect human experience at multiple levels from perception to thought patterns and life reflections, before concluding by placing this analogy inside a larger project of using the internal mechanism of AI to better understand our own minds.
