Benchmarking Popular Opensource LLMs: Llama2, Falcon, and Mistral

In this blog, we will show the summary of various open-source LLMs that we have benchmarked. We benchmarked these models from a latency, cost, and requests per second perspective. This will help you evaluate if it can be a good choice based on the business requirements. Please note that we don't cover the qualitative performance in this article - there are different methods to compare LLMs which can be found here.

Use cases Benchmarked

The key use cases across which we benchmarked are:

1. 1500 Input tokens, 100 output tokens (Similar to Retrieval Augmented Generation use cases)
2. 50 Input tokens, 500 output tokens (Generation Heavy use cases)

Benchmarking Setup

For benchmarking, we have used locust, an open-source load-testing tool. Locust works by creating users/workers to send requests in parallel. At the beginning of each test, we can set the Number of Users and Spawn Rate. Here the Number of Users signify the Maximum number of users that can spawn/run concurrently, whereas the Spawn Rate signifies how many users will be spawned per second.

In each benchmarking test for a deployment config, we started from 1 user and kept increasing the Number of Users gradually till we saw a steady increase in the RPS. During the test, we also plotted the response times (in ms) and total requests per second.

In each of the 2 deployment configurations, we have used the huggingface text-generation-inference model server having version=0.9.4. The following are the parameters passed to the text-generation-inference image for different model configurations:

2. LLama2-7B
3. LLama2-13B
4. LLama2-70B
5. Falcon-40B-Instruct

The following table shows a summary of benchmarking LLMs:
