Tokenflood – simulate arbitrary loads on instruction-tuned LLMs

Hi everyone, I just released an open source load testing tool for LLMs: https://github.com/twerkmeister/tokenflood === What is it and what problems does it solve? === Tokenflood is a load testing tool for instruction-tuned LLMs hat can simulate arbitrary LLM loads in terms of prompt, prefix, and output lengths and requests per second. Instead of first collecting prompt data for different load types, you can configure the desired parameters for your load test and you are good to go. It also let's you assess the latency effects of potential prompt parameter changes before…

In plain words

Tokenflood is an open-source load testing tool designed for instruction-tuned large language models. It allows developers to simulate arbitrary loads by configuring prompt length, prefix length, output length, and requests per second without needing to collect real prompt data first. The tool helps teams building latency-sensitive LLM applications test self-hosted model setups and evaluate how changes to prompt parameters would affect performance before implementation.

From the sources

Tokenflood allows you to 1) figure out how to slash LLM latency by adjusting prompt parameters 2) assess the load curve of LLM providers before going to production with them
