What this part means
The lower label selects a particular version, component, or indexed member of the quantity. For example, x₀ and xₜ can be values at different positions.
Its job in the formula
A subscript distinguishes a version, component, step, or member of a quantity. It does not automatically mean multiplication.

The passage around this formula
Autoregressive decoding sits at the far left of that graph. Generating one token requires reading essentially every weight and the accumulated key-value cache once, and performing roughly two arithmetic operations per parameter. At one byte per weight the intensity is about two operations per byte; at four bits per weight, about four. Pope and colleagues formalised this partitioning problem for large transformers and showed how latency, throughput and cost trade off under different sharding strategies, with generation and prefill behaving as different regimes [ 3 ] . The bound that matters on a device follows immediately: if W bytes of weights and cache must cross the memory bus for each…

A subscript is a label attached below a symbol. It often selects a time step, component, category, or member of a sequence.
