Generation 1 — Standalone Models (2018–2022)

Generation 1 — Standalone Models (2018–2022)

Short summary

Generation 1 LLMs (2018–2022) are stateless models wrapped in three layers: UI creates smooth interaction, Orchestration manages memory/context/routing via conversation replay, and the Model predicts tokens sequentially. Perceived memory is an illusion—the orchestration layer simulates continuity by replaying history, not the model itself.

  • Generation 1 models (GPT-3, Claude, Gemini) are stateless—each prompt is processed independently with no persistent memory
  • The 3-layer architecture (UI + Orchestration + Model) separates concerns; orchestration creates the illusion of memory by replaying conversation history
  • The model layer only predicts tokens; continuity, safety filtering, routing, and context management happen entirely in the orchestration layer
