alleryStart learning →The base pretrained model fine-tuned for InstructGPT is
AGPT-2 with 1.5 billion parameters
BGPT-3 with up to 175B parameters
CT5 with 11 billion parameters total
DLLaMA with 70 billion parameters
Answer & Solution
Correct answer: B. GPT-3 with up to 175B parameters
The starting checkpoint is GPT-3 (up to 175B).
InstructGPT is fine-tuned variants of these checkpoints — not pretrained from scratch.
