Input Tokens — the LLM reading of Earth

The starting point of every forward pass: a tokenized input sequence, not yet placed into the embedded space. Just as Earth is the fixed point of departure and return, token input is where exitus (ascent through the layers) begins and reditus (the generated token folded back into the sequence) ends.

Earth (Terra) — Center

The central (and spherical) Earth is surrounded by a series of hollow and transparent globes, one above the other, and each of course larger than the one below. Earth itself does not move — it is the fixed low point from which the medieval imagination ascends through the spheres, and to which the LLM's generation cycle always returns.
