JAZ framework lets LLMs run complex tasks with minimal code

Researchers introduced JAZ, a lightweight agent framework that lets language models handle tasks usually requiring extra systems like memory or self-improvement. The framework uses a single invoke primitive, where the LLM generates executable code on the fly, including recursive calls. JAZ avoids custom tools or external systems, relying only on prompting.

Key points

  • JAZ uses an `invoke` primitive where LLMs generate executable code without manual tool design
  • Outperformed Letta (MemGPT) by 8% on recall tasks at half the cost in StuLife benchmark
  • Beat ACE by 4% on self-improvement tasks in AppWorld, per the authors

JAZ outperformed existing agents like Letta (MemGPT) by 8% on long-term recall tasks in the StuLife benchmark, using half the resources. It also beat ACE by 4% on self-improvement tasks in AppWorld, the authors claim. The paper argues that a minimalist design—just the agent loop plus constraints—can replace specialized systems for many workflows.
