Answers and explanations appear as you take the quiz.

  1. What distinguishes an 'open-weights' model from a fully open-source model under the OSI definition?
    • Weights are released, but data, code or open terms may not be
    • There is no meaningful difference between the two terms
    • Open-weights models cannot be downloaded or run by anyone at all
    • Open-source models never release their trained weights
  2. A team can download a model checkpoint. What should it check before using the model in a product?
    • Assume downloading grants every commercial and redistribution right
    • The permissions and restrictions in the license for that exact release
    • Rely only on the model family name
    • Treat the download page as a replacement for license terms
  3. Why might a downloaded model need more than its weight file for compatible inference?
    • A weight file must include every training example
    • Only the original author can load any model
    • Architecture, tokenizer or preprocessing, configuration and runtime determine how weights are interpreted
    • A model cannot run without a cloud account
  4. How can fine-tuning affect a model’s refusal behavior?
    • It guarantees every refusal is preserved
    • It makes the model permanently unable to answer benign requests
    • It remotely updates the original provider’s hosted model
    • It can change refusal behavior, so the adapted model should be reevaluated
  5. What is an important benefit of open weights for researchers?
    • They can inspect activations and run fine-tuning experiments
    • They receive guaranteed higher scores on every benchmark
    • They no longer need any computing hardware at all
    • They get free access to closed models' training data
  6. What should an operator keep when modifying an open-weight model?
    • Only a public download counter
    • A record of modifications and a rollback version
    • A claim that all adaptations are compliant
    • The base model’s marketing slogan
  7. Which claim is supported by access to model weights alone?
    • The training data are public
    • The model can be reproduced exactly
    • The parameters can be downloaded under the release’s terms, but other components may still be missing
    • Every use is permitted commercially
  8. What should a team check before using a quantized open-weight checkpoint?
    • Only the model family name
    • That quantization guarantees identical quality
    • That the checkpoint needs no tokenizer or runtime
    • Its task behavior and resource use on the intended hardware
