Continual learning for AI agents occurs at three layers: model, harness, and context, enabling systems to improve over time

intermediate Published 5 Apr 2026
Action Steps
  1. Identify the three layers of agentic systems: model, harness, and context
  2. Understand the techniques for updating model weights, such as SFT and RL
  3. Recognize the challenge of catastrophic forgetting and its impact on model performance
  4. Explore the concept of harnesses and their role in driving agents
  5. Consider the importance of context in configuring and improving agents
Who Needs to Know This

AI engineers, researchers, and developers can benefit from understanding these layers to build more effective agentic systems, and product managers can use this knowledge to design better AI-powered products

Key Insight

💡 Continual learning is not limited to updating model weights, but can also occur at the harness and context layers
