What this part means
A raised number can be a power. When it is a label or bound, it selects a case or the upper limit of a sum; the formula’s structure distinguishes these uses.
Its job in the formula
A raised mark can be a power or an index. Its position and the surrounding notation determine which.

The passage around this formula
normalizing each sampled response’s reward against the mean and standard deviation of a group of G responses to the same prompt rather than against a separately trained critic network [ 13 ] . Lambert and colleagues, building the fully open Tulu 3 post-training recipe, named the general approach explicitly, describing it as “a novel method we call Reinforcement Learning with Verifiable Rewards,” and used it alongside supervised fine-tuning and preference optimization rather than as a wholesale replacement for either [ 15 ] . The clearest large-scale demonstration is DeepSeek-R1: Guo and colleagues report training a model with reinforcement learning alone against a purely rule-based reward —…

An exponent tells how a base is used in multiplication. In x³, x is the base and 3 is the exponent: x³ = x × x × x.
