AIF-C01 Practice Question 86: Fine Tuning Training Cost

AWS Certified AI Practitioner (AIF-C01) · Test 9 · question 6 of 10

Applications of Foundation Modelsmedium

A team plans to fine-tune a foundation model in Amazon Bedrock. Their training dataset contains 2 million tokens and the job is configured to run for 3 epochs. For how many tokens will they be charged for the training itself, in addition to a monthly storage fee for the custom model?

Select one answer
Show answer and explanation

Answer:

  • A. About 6 million tokens

Amazon Bedrock bills model customization by the number of tokens the model processes: *"the number of tokens in training data corpus × number of epochs"*, plus monthly model storage. Each epoch is one full pass over the dataset, so 2 million tokens × 3 epochs = 6 million tokens (option A).

- B is wrong because it counts a single pass over the data and ignores that every additional epoch processes the full dataset again. - C is wrong because it adds the numbers (2 + 3) instead of multiplying tokens by epochs. - D is wrong because it takes the epoch count as if it were a token count and ignores the size of the dataset.
