Learning to Learn-at-Test-Time: Language Agents with Learnable Adaptation Policies

📰 ArXiv cs.AI

Language agents can learn to adapt at test time with learnable adaptation policies, improving performance through repeated interactions

advanced Published 2 Apr 2026
Action Steps
  1. Define the problem and identify the need for adaptation in language agents
  2. Develop a learnable adaptation policy that can update the actor policy based on experience
  3. Implement Test-Time Learning (TTL) to enable iterative refinement of performance
  4. Evaluate and optimize the adaptation policy for downstream improvement
Who Needs to Know This

ML researchers and AI engineers can benefit from this concept to develop more efficient language agents, while product managers can apply it to improve chatbots and virtual assistants
