Tt\mathcal T_t

Why this formula appears here

where πθ,t\pi_{\theta,t} is the model policy at time t ; HtH_t is the harness and its context/state machinery; Tt\mathcal T_t is the available tool set; PtP_t is the permission and sandbox policy; EtE_t is the execution environment; VtV_t is the collection of verification functions; and UtU_t represents user and institutional authority. The time index is essential. OpenAI can update the model, CLI, documentation, or cloud runtime without changing the product name.
