Article Summary
LiquidAI announced the release of QAD Q4_0 GGUFs for their LFM2.5 series models (230M to 2.6B parameters). These checkpoints utilize Quantization-Aware Distillation (QAD), a technique that preserves the high performance of a large 'teacher' model while keeping the small 'student' model quantized (Q4_0). Benchmark comparisons show that the QAD checkpoints significantly minimize the accuracy loss typically associated with quantization, retaining over 96% of the full BF16 baseline accuracy across various benchmarks (GPQA Diamond, MMLU-Pro, etc.). Crucially, these models maintain the speed and low memory footprint of native Q4_0 GGUFs while offering comparable or better performance than existing post-training quantization methods.Key Points
- The new QAD Q4_0 checkpoints significantly reduce the performance drop associated with quantizing smaller LLMs (LFM2.5) for edge deployment.
- Users can achieve highly accurate performance (retaining ~97% of BF16 baseline) while maintaining the fast, low-memory characteristics of Q4_0 GGUFs.
- The models demonstrate optimized throughput improvements across various edge hardware targets, including consumer CPUs and mobile ARM chips.
