Enterprise AI Analysis: GAMMA: Global Bit Allocation for Mixed-Precision Models under Arbitrary Budgets
Optimizing LLM Deployment with Global Bit Allocation
GAMMA is a novel framework for mixed-precision quantization in LLMs, optimizing bit allocation without retraining. It improves budget-accuracy trade-offs, particularly in low-bit regimes, and offers significant performance gains over existing methods by reusing learned sensitivity scores across different budgets, reducing per-budget adaptation from hours to minutes.

GAMMA's Two-Stage Pipeline for Optimal Bit Allocation
GAMMA employs a sophisticated two-stage approach to optimize mixed-precision quantization for large language models. This method avoids the pitfalls of quantization-aware training by learning bit-selection preferences in a post-training pipeline.

Re-solve for New Budgets
Stage I involves learning budget-aware precision preferences for each linear module through a differentiable relaxation. An augmented Lagrangian constraint enforces exact budget compliance, moving beyond soft penalties that can lead to misalignments. Stage II then converts these learned soft preferences into exact, budget-feasible discrete assignments using integer programming. A key innovation is score reuse: a single training run generates preferences that serve arbitrary deployment targets, requiring only minutes to re-solve the integer program for new budgets.
Superior Accuracy Across LLMs and Bit Regimes
GAMMA demonstrates significant performance gains, especially in extreme low-bit compression scenarios, preventing capability collapse often seen in uniform quantization. This allows for practical LLM deployment at substantially smaller memory footprints without compromising accuracy.

Average Accuracy at 3.0 bits (Qwen3-8B)
GAMMA consistently outperforms fixed-precision and search-based mixed-precision baselines, especially under extreme compression, achieving significant accuracy improvements. It matches fixed 3-bit quality at 2.5-bit average precision.
Across Llama and Qwen models (8B-32B), GAMMA outperforms both fixed-precision baselines (up to +12.99 Avg.) and search-based mixed-precision methods (up to +7.00 Avg.). Notably, it can match fixed 3-bit quality at 2.5-bit average precision, pushing practical deployment toward lower-bit regimes effectively.
Unprecedented Efficiency: Rapid Adaptation for Diverse Budgets
GAMMA fundamentally redefines efficiency in mixed-precision quantization by decoupling sensitivity learning from budget-specific allocations. This results in dramatically reduced adaptation times and robust performance across varying deployment scenarios.

GAMMA significantly reduces per-budget adaptation time from hours to minutes by reusing learned allocation scores, making it highly efficient for diverse deployment targets. This is achieved through a post-training pipeline without weight retraining. A single training run serves arbitrary deployment targets, making it ideal for dynamic resource allocation needs in enterprise environments.
