BudgetBench Protocol Evaluates Memory Strategies for Local LLM Agents

2026-09-25

A new protocol, BudgetBench, has been introduced to evaluate memory strategies for local large language model agents by treating the per-call input-token budget as a key variable. The system aims to measure quality, budget utilization, latency, and budget-violation rates.

A new protocol called BudgetBench has been introduced to evaluate memory strategies for local large language model agents. It treats the per-call input-token budget as a key variable to measure quality, budget utilization, latency, and budget-violation rates.

Key facts

  • BudgetBench is a protocol and harness for evaluating memory strategies in local large language model agents.
  • The protocol treats the per-call input-token budget as the independent variable for comparison.
  • Outcomes recorded include quality, budget utilization, latency, and budget-violation rates.
  • Pilot studies revealed budget-compliance failures and non-monotonic quality curves.
  • The protocol features a swappable MemoryStrategy contract and explicit budget enforcement.
