Published on September 26, 2026, the note presents JAZ, a framework using a single recursive code primitive for agent loops, and reports a claim of lower cost and better performance than two alternatives.
A September 26, 2026 publication describes JAZ as a recursive-agent system built around a single code primitive for running loops. The cited preview characterizes its agents as able to use tools and switch between workflow steps.
The publication claims JAZ can outperform Letta and ACE at lower cost; this is the source's claim, not a conclusion verified here. The comparison may interest engineers assessing whether simpler loops can replace frameworks specialized in memory and self-improvement. Consult the original publication and check its methods, tasks, metrics, and costs before drawing conclusions.
