Unique: Qwen2.5-1.5B's small parameter count (1.5B) enables large batch sizes on consumer GPUs, and its efficient attention implementation (RoPE, grouped query attention) reduces per-token memory overhead. vLLM's dynamic batching automatically groups variable-length requests, eliminating manual padding logic.

vs others: Achieves 5-10x higher throughput than sequential inference on the same GPU; smaller model size allows larger batch sizes than 7B+ models, making it ideal for high-concurrency services.
