Design of a ChatGPT System
Explore the design of a ChatGPT-like system, examining its key components and the workflow.
We have identified the requirements, storage needs, and foundational components. Now, we will detail the system design to understand how these components ensure real-time, context-aware conversations.
High-level design of ChatGPT
The high-level design illustrates how the system handles real-time conversations. The following workflow outlines the component interactions.
The workflow for the high-level design is provided below:
User input: The user submits a text prompt via the interface or API.
Gateway processing: The API gateway authenticates the request, applies rate limiting, manages the session, and forwards the prompt to the model server.
Model inference: The AI model processes the prompt using conversation history. Responses are cached for retrieval and logged in the database.
Response delivery: The generated response is returned to the user via the API gateway.
Feedback loop: User feedback is collected to improve system performance and fine-tune future models. ...
Is a typical cache (like LRU or TTL-based) sufficient for storing AI-generated responses?
Let’s examine the specific components that enable this architecture.
