Layered memory for long-horizon research agents
A post dated April 19, 2026 describes ML-Master 2.0’s Hierarchical Cognitive Caching, with short-, medium-, and long-term memory, and reports a 56.44% medal rate on MLE-Bench after a 24-hour run.

What happened and what to do
In a post published on April 19, 2026, the ML-Master 2.0 team describes Hierarchical Cognitive Caching: short-, medium-, and long-term memory for retaining research information across experiments and sessions. The team reports a 56.44% medal rate on MLE-Bench after a 24-hour run.
A company using agents for long-running tasks could implement tiered state storage, retention and retrieval rules, and monitoring for consistency across sessions. The solution should be evaluated on representative tasks using continuity, retrieval, and cost metrics, without assuming the reported result will transfer to another setting.
How the consultancy can help
Wendelmaques can diagnose how a company’s agents preserve state and context, define a suitable memory architecture, and deliver an implementation with monitoring and operations scoped to the use case.
