Episode notes
Scale And Transformer Architecture Matter
- GPT-3 uses the transformer architecture and massive web-scale text like Common Crawl for training.
- Its scale (175 billion parameters) is two orders of magnitude larger than GPT-2 and enables broader capabilities.
Few-Shot Is Priming, Not Retraining
- Few-shot means priming the pre-trained model with examples at inference time without weight updates.
- This mimics human rapid adaptation and enables solving new tasks from a couple examples.
Surprising Strengths, Strange Weaknesses
- GPT-3 can perform surprising tasks like two-digit arithmetic by learning patterns from text.
- Its strengths are uneven: it solves some complex tasks well and fails at simple ones like four-digit math.
