SpecServe is a novel system that accelerates LLM inference through adaptive speculative decoding, dynamically optimizing performance based on workload conditions.

• Leverages lightweight draft models with heavyweight LLM verification
• Adaptively adjusts speculation length based on current system load
• Achieves up to 2.3× throughput improvement while meeting latency SLOs
• Includes ingenious scheduling policies that optimize resource allocation

This research enables more efficient LLM deployment in production environments, allowing engineering teams to maintain performance standards while reducing computing costs and energy consumption.
