Fireworks has developed the 3D FireOptimizer as part of its FireOptimizer toolkit to assist in optimizing LLM serving by automatically navigating complex tradeoffs between speed, cost, and quality, tailored to unique workload requirements. This tool examines various factors such as model architecture, hardware selection, quantization, speculation strategies, and parallelism to determine optimal configurations without requiring users to manually sift through an extensive array of possibilities. By leveraging performance data, rule-based heuristics, and customer-specific tuning, 3D FireOptimizer identifies configurations that enhance quality, throughput, and latency, thereby offering significant improvements over baseline setups. Through case studies, Fireworks demonstrates the tool's ability to improve performance in different scenarios like code completion and chatbot applications, emphasizing its practical utility in real-world production environments.
