📄 Description

Problem

cloud-0024 asks for the FP16 memory footprint of a 7B parameter model.

The correct calculation: 7B params x 2 bytes (FP16) = 14 GB

Option at correct_index: 2 states "12 GB" and "7x more memory." But 7x more than the 1B model (2 GB) is 14 GB, not 12 GB. The option contradicts its own reasoning.

Option at index 3 correctly states 14 GB.

Fix

Changed correct_index from 2 to 3. No other changes.

Test plan

  • Math verified: 7,000,000,000 x 2 = 14,000,000,000 bytes = 14 GB
