  1. How does speculative decoding speed up generation from a large model?
    • Iyo diki dhizaini modhi inofungidzira akati wandei ma tokeni ayo hombe modhi inosimbisa mukuenderana
    • Kumanikidza muenzaniso kusvika hafu yehukuru hwayo zvachose
    • Kubvisa iyo yekutarisisa michina
    • Kudzidzira modhi pane mamwe data
  2. For a large model at low batch size, why can one-token autoregressive decoding be slow?
    • Each token requires internet access
    • Repeated reads of large model weights can make decoding memory-bandwidth bound
    • The model permanently stores a full copy of every possible output
    • The tokenizer performs the model’s matrix multiplications
  3. In greedy speculative decoding, what happens at the first token where draft and target predictions disagree?
    • The whole conversation is thrown away and restarted from scratch
    • Iyo dhizaini modhi inodzidziswa zvakare nekukurumidza
    • The matching prefix is kept, the target token is used at the mismatch, and later draft tokens are discarded
    • The goho quality zvachose degrades
  4. Under exact speculative sampling, how does the output distribution compare with sampling from the target model alone?
    • It is always lower quality but faster
    • It is identical only when the draft model is larger
    • It becomes deterministic regardless of target sampling
    • It is identical in distribution
  5. Chii chinonyanya kutarisisa kukurumidza kubva pakufungidzira decoding?
    • Mwero wekugamuchirwa wefungidziro dzemodhi
    • Ruvara rweGPU
    • Hurefu hwezita remuenzaniso
    • Nguva yezuva
  6. Chii chinonzi Medusa neEAGLE zvakafanana semafambiro?
    • Vanoda quantum hardware
    • Ivo vanobvisa kudiwa kweyakasiyana yakamira dhizaini modhi
    • Vanodzima iyo inotarirwa modhi
    • Vanoshanda chete pamifananidzo
  7. What should a serving team measure before claiming speculative decoding will speed up its workload?
    • Only the target model’s parameter count
    • Only whether the draft produces fluent text
    • Draft cost, target verification cost, accepted tokens and end-to-end latency under representative traffic
    • The number of tokenizer files
  8. In exact speculative sampling, what happens when a proposed token is rejected?
    • The whole conversation is discarded
    • The target model is permanently changed
    • The rejected token is kept without verification
    • A correction step samples from the distribution needed to preserve the target model’s output distribution
