A language model processes a sequence of tokens one by one. To compute the representation for the current token, it uses an attention mechanism that only considers a local context. This context consists of the current token plus a fixed number of the most recent preceding tokens. The total number of tokens in this context is defined by a 'window size' parameter.

Given the sequence [T1, T2, T3, T4, T5, T6, T7, T8, T9, T10] and a window size of 4, which specific tokens form the context when the model is processing token T8?
