JAZ and evaluating recursive agent loops
Published on September 26, 2026, the post describes JAZ, a minimalist framework that uses a single recursive primitive for agent loops, and claims it may outperform Letta and ACE at lower cost.

What happened and what to do
On September 26, 2026, the post described JAZ as a system that uses a single recursive code primitive to run agent loops. Its preview mentions agents that use tools and alternate workflow steps. The post claims the system may outperform Letta and ACE at lower cost, but the supplied text gives no metrics; this is a claim to evaluate, not an independently confirmed result.
A company can test whether simpler loops meet its process needs before adopting frameworks focused on memory and self-improvement. A pilot could compare cost, answer quality, tool use, reliability, and maintainability across representative workflows, using criteria and limits defined in advance.
How the consultancy can help
Wendelmaques can assess workflows and evaluation criteria, design a controlled comparison of approaches, and implement a pilot with monitoring for cost, quality, and reliability. The scope can include operating the solution on the client’s infrastructure.
