Qwen3.5-4B inference accelerated with quantization and speculative decoding

By PulseAugur Editorial · [1 sources] ·

Researchers have developed an efficient inference system for the Qwen3.5-4B language model, achieving a 6.978x speedup on an NVIDIA A10G GPU. Their approach combines a quantized target model with speculative decoding, employing quantization-aware distillation to maintain accuracy. A specialized drafter model, optimized for the quantized target, was trained in two stages to accelerate decoding. This method also incorporates quantization and sliding-window attention to reduce overhead and improve long-context latency, ultimately ranking third in the Efficient Qwen Competition. AI

IMPACT This research offers practical insights into optimizing LLM inference for resource-constrained environments, potentially lowering deployment costs.
