UnverifiedSystem prompts (System Prompt) can constrain large model behavior to a specific role, style, and output format.77% similarUnverifiedIn the standard large language model interaction architecture, the system prompt is injected into the model's context at the beginning of each conversation to define the model's role, behavioral boundaries, and task rules.72% similarUnverifiedThe context window of a large language model determines the upper limit of information the model can process in a single inference.71% similarUnverifiedEach inference call to a large model is an independent forward pass; the model weights are completely fixed during inference and there is no mechanism to preserve state across conversation sessions.71% similar
