Kudzika Kwakadzika
Normal language models generate one token per forward pass, which is slow because each step must wait for the previous one. Medusa adds lightweight feed-forward heads on top of the frozen base model; each head predicts a token a few positions ahead (head 1 predicts the next token, head 2 the token after, and so on). These predictions form a tree of candidate continuations. The full model then verifies the whole tree in one pass using a 'tree attention' mask, accepting the longest prefix that matches what the model would have produced anyway. For Medusa-1, the backbone stays frozen and original-model rejection sampling can preserve the base model's output distribution, enabling lossless inference acceleration. Medusa-2 jointly trains the heads and backbone with a special recipe that preserves the backbone's next-token capability while improving head prediction. The paper also studies typical acceptance, which can increase acceptance and maintain similar generation quality but does not make the same exact distribution-matching guarantee.

Nekuonesa fungidziro idzi mukupfuura kamwe chete, inomhanyisa kugadzirwa kwemavara zvingangoita 2-3x pasina kuchinja kugovera kwemodhi.
Misoro yekuwedzera yeMedusa inofanotaura chii?
Musoro wega wega weMedusa unofanotaura chiratidzo akati wandei mune ramangwana, saka akati wandei tokeni anogona kutaurwa kamwechete.
Under which Medusa configuration does the paper describe lossless inference acceleration?
The Medusa paper identifies Medusa-1, which freezes the backbone, as enabling lossless acceleration; exact rejection sampling verifies accepted candidates against the base model distribution.
