    oai_token-act-pair · gpt-4o-miniTriggered by @bot

    This neuron detects mathematical or technical notation involving radius-related variables (rho, Radius) and geometric measurements, especially in mathematical formulas and code.

    oai_token-act-pair · claude-3-7-sonnet-20250219Triggered by @neilrathi

    formal mathematical/technical notation, especially equations with Greek-letter variables, derivatives, trigonometric expressions, and coordinate/radius/amplitude parameters in physics or graphics contexts.

    oai_token-act-pair · gpt-5Triggered by @jyhe0408

    mathematical and technical notation, particularly variables and symbols in equations (especially Greek letters like rho, theta, phi, and psi).
