The "T" in GPT stands for this neural network architecture introduced in 2017 that revolutionized natural language processing through self-attention mechanisms.
Difficulty: EasyThis attention variant adds linear bias terms based on position distance instead of learned embeddings, enabling extrapolation to longer sequences without additional training.
Difficulty: MediumThis initialization scheme scales weights by 1/√d to prevent output variance from exploding with layer depth, standard for attention projections.
Difficulty: HardWhen you type a message to an AI assistant, each word or word-piece is converted into one of these basic units that the model actually processes.
Difficulty: EasyThis OpenAI paper introduced in-context learning by demonstrating that GPT-3's 175 billion parameters enabled task performance through examples alone, without gradient updates.
Difficulty: MediumThis research paper demonstrated that attention patterns in middle layers often attend strongly to the first token regardless of content, acting as a "no-op" attention pattern.
Difficulty: HardThis technique uses human ratings of AI responses to train a reward model, which then guides the AI to produce more helpful and safer outputs.
Difficulty: EasyThis technique used in RLHF training constrains how far the updated policy can deviate from the reference policy at each step, preventing catastrophic forgetting of pre-trained capabilities.
Difficulty: Medium
