BudgetMem introduces a multi-stage modular pipeline (Filter → Parallel Extraction → Summary) for runtime memory extraction. A lightweight, RL-trained router makes query-aware decisions at each module, selecting budget tiers (LOW/MID/HIGH) to balance performance and cost. This dynamic approach avoids wasteful offline preprocessing and ensures computation is triggered only when needed, based on the current query and intermediate states.
BudgetMem offers three complementary tiering strategies:
- Implementation Tiering: Varies module implementation complexity, from lightweight heuristics (LOW) to BERT-based models (MID) and full LLM-based processing (HIGH), directly impacting computational budget and quality.
- Reasoning Tiering: Adjusts the inference behavior within a fixed model, moving from direct generation (LOW) to Chain-of-Thought (MID) and multi-step/reflection-style reasoning (HIGH) for more deliberative processing.
- Capacity Tiering: Changes the underlying model size used for a module (e.g., small, medium, large LLMs), offering a direct trade-off between model capacity, performance, and cost.
BudgetMem consistently achieves superior accuracy-cost frontiers compared to baselines, demonstrating significant gains in high-performance settings and better efficiency under tight budgets.
- Implementation and Capacity Tiering provide broader cost ranges, making them suitable for exploring wide budget coverage and pushing performance boundaries.
- Reasoning Tiering offers fine-grained quality control within a more concentrated cost region, ideal for refining performance at similar cost levels.
- Reward-scale alignment and optimal retrieval size (e.g., 5 chunks) are crucial for stable training and balancing evidence sufficiency against context noise.
Unlocking Cost Efficiency
Up to 60% Reduced Memory Extraction CostsBudgetMem's query-aware, on-demand memory extraction significantly reduces computational overhead compared to traditional offline preprocessing, leading to substantial cost savings across diverse tasks and LLM backbones. This efficiency allows for higher quality outputs at tighter budgets.
| Tiering Strategy | Focus | Cost-Performance Impact |
|---|---|---|
| Implementation Tiering | Varying module implementation (heuristics to LLM-based) | Broad cost range, rapid performance gains at moderate budgets, suitable for wide budget coverage. |
| Reasoning Tiering | Varying inference behavior (direct to multi-step reflection) | Concentrated cost range, provides fine-grained quality improvements at similar costs. |
| Capacity Tiering | Varying module model size (small to large LMs) | Broad cost range, achieves best quality in high-budget regimes, excellent for pushing performance boundaries. |

Reinforcement Learning for Dynamic Routing
The core of BudgetMem's adaptability lies in its lightweight router, trained with reinforcement learning to make query-aware, module-wise tier selections. This dynamic routing balances task performance against memory extraction cost, ensuring optimal resource allocation. A critical component for stable training and meaningful cost-performance control is reward-scale alignment, which normalizes disparate reward magnitudes.
