The post NVIDIA Launches GenAI-Perf for Optimizing Generative AI Model Performance appeared on BitcoinEthereumNews.com.

Timothy Morano Aug 02, 2024 02:46 NVIDIA introduces GenAI-Perf, a new tool for benchmarking generative AI models, enhancing performance measurement and optimization. NVIDIA has unveiled a new tool, GenAI-Perf, aimed at enhancing the performance measurement and optimization of generative AI models. According to the NVIDIA Technical Blog, this tool is incorporated into the latest release of NVIDIA Triton and is designed to aid machine learning engineers in finding the optimal balance between latency and throughput, especially crucial for large language models (LLMs). Key Metrics for LLM Performance When dealing with LLMs, performance metrics extend beyond traditional latency and throughput. Key metrics include: Time to first token: The time between when a request is sent and the receipt of the first response. Output token throughput: The number of output tokens generated per second. Inter-token latency: The time between intermediate responses divided by the number of generated tokens. These metrics are essential for applications where quick and consistent performance is paramount, with time to first token often being the highest priority. Introducing GenAI-Perf GenAI-Perf is designed to accurately measure these specific metrics, helping users determine optimal configurations for peak performance and cost-effectiveness. The tool supports industry-standard datasets like OpenOrca and CNN_dailymail and facilitates standardized performance evaluations across various inference engines through an OpenAI-compatible API. GenAI-Perf is intended to be the default benchmarking tool for all NVIDIA generative AI offerings, including NVIDIA NIM, NVIDIA Triton Inference Server, and NVIDIA TensorRT-LLM. This facilitates easy comparisons among different serving solutions that support the OpenAI-compatible API. Supported Endpoints and Usage Currently, GenAI-Perf supports three OpenAI endpoint APIs: Chat, Chat Completions, and Embeddings. As new model types emerge, additional endpoints will be introduced. GenAI-Perf is also open source, accepting community contributions. To get started with GenAI-Perf, users can install the latest Triton Inference Server SDK container from…
