Parametric Memory(PM)
Knowledge implicitly stored within model parameters, enabling fast context-free knowledge retrieval for multi-agent agentic AI systems
In 30 seconds
- What
- Stores domain knowledge in model weights during training, letting agents retrieve facts and patterns without explicit context or retrieval systems.
- When to use
- Multi-agent systems where agents need fast, shared access to common knowledge without querying external databases or passing large context windows.
- Watch out
- Knowledge becomes stale or incorrect if the base model is outdated, and you cannot easily update or correct specific facts without retraining.
