Abstract: There are provided systems and methods for a quantitative analysis tool for inference speed and performance of AI models. An online transaction processor or other service provider may provide computing services and platforms to entities, which may include services that utilize AI models including LLMs. To provide more efficient training and testing of AI models, a service provider may utilize a quantitative analysis tool that executes operations for algorithmic techniques utilized to calculate model throughput parameters include prefill latency, decoding latency, and other performance metrics.
