Claims

AI agents mostly confuse memory storage with genuine learning from experience.
Simple full-context learning outperforms more specialized agent memory architectures on the proposed benchmark.
Claude Sonnet 4.6 achieves leading results using plain context rather than specialized memory systems.
The paper introduces a new test specifically designed to evaluate whether AI agents truly improve with accumulated experience.

Key quotes

This paper proposes a new test to see whether AI agents truly get better as they gain experience and finds they mostly still confuse memory with learning. Shows that simple full-context learning beats the more specialized memory systems, with Claude Sonnet 4.6 using plain [context].
