🔑 增強重點摘要

• •Custom instructions and memory features leverage a long-term retrieval mechanism that allows the model to persist user preferences across distinct sessions, moving beyond the standard stateless transformer architecture.
• •Privacy controls allow users to explicitly manage, view, and delete stored memories, addressing data sovereignty concerns regarding how personal context is utilized for model fine-tuning and inference.
• •The implementation of these features utilizes a vector-based storage system that enables the model to perform semantic searches over a user's historical interactions to retrieve relevant context before generating a response.

🛠️ 技術深入

• •Memory mechanism: Employs a retrieval-augmented generation (RAG) architecture where user-provided facts are indexed and queried based on semantic similarity to the current prompt.
• •Custom Instructions: Operates as a system-level prompt injection that prepends user-defined constraints to the conversation's system message, effectively steering the model's persona and output format.
• •Data Lifecycle: Memories are stored in a dedicated database separate from the primary model weights, allowing for real-time updates without requiring model retraining or fine-tuning.
