Explanation:
The maxTokens parameter in Amazon Bedrock controls the maximum number of tokens that can be generated in the model's output (completion).
- Option B is correct: It sets the maximum length of generated output tokens.
- Option A is incorrect: Input length is typically controlled by other parameters or model constraints, not maxTokens.
- Option C is incorrect: maxTokens only controls the output tokens, not the combined input+output length.
- Option D is incorrect: Vocabulary size is a fixed property of the model, not a configurable parameter.
Setting maxTokens to 256 ensures that the generated response will not exceed 256 tokens, which is useful for controlling response length and managing costs.
