Introduction to OpenHermes 2.5 - A Cutting Edge AI Model

The AI landscape has seen massive advances in recent years, with innovative new models being developed at a rapid pace. One of the latest buzzworthy models is OpenHermes 2.5 - an open source AI system that demonstrates extremely impressive capabilities despite its relatively small size.

In this post, we'll provide an overview of OpenHermes 2.5, discuss its key features and performance benchmarks, provide a step-by-step guide on using the model, and compare it to other leading AI systems like LLAMa-213B and GPT-4.

What is OpenHermes 2.5?

OpenHermes 2.5 Mistral 7B is a cutting edge Mistral fine-tuned model based on the Mistral 7B architecture. It has achieved further performance improvements by undergoing additional training on primarily GPT-4 generated data, as well as other high-quality datasets. Specifically, OpenHermes 2.5 was trained on 100,000 entries of GPT-4 generated text, which accounted for around 7-14% of its total training data. The remainder of its dataset came from sources like Glaive AI, a16z, and dozens of other organizations and individuals. This supplementary training on synthetic GPT-4 data has led to considerable boosts in OpenHermes 2.5's capabilities, allowing it to excel across a diverse range of AI benchmarks and tasks.

Key Features of OpenHermes 2.5

Here are some of the key capabilities and features of OpenHermes 2.5:

  • State-of-the-art performance in benchmarks like BigBench, TruthfulQA, and HellaSwag
  • Significantly improved abilities compared to the base Mistral 7B model
  • Surpasses OpenChat 3.5 despite being a smaller model
  • Strong performance in coding tasks and code generation
  • Refusal to provide unethical or illegal information, demonstrating improved ethics

Benchmark Results and Performance of OpenHermes 2.5

Numerous benchmarks have been conducted to evaluate OpenHermes 2.5 against other leading AI models. The results demonstrate that it achieves state-of-the-art performance despite its relatively small size.

In BigBench, TruthfulQA, and HellaSwag evaluations, OpenHermes 2.5 attained the highest scores among all Mistral fine-tuned models. It even exceeded the performance of OpenChat 3.5, which is considered comparable to ChatGPT.

Tests focused specifically on coding also show promising results. In HumanEval coding tasks, OpenHermes 2.5 scored around 4 times higher than LLAMa-27B, indicating a significant enhancement in code generation abilities thanks to its training on GPT-4 generated code data.

How to Use OpenHermes 2.5

Using OpenHermes 2.5 is straightforward with the right tools. Here is a simple step-by-step guide to start leveraging this powerful AI model on your own computer:

Downloading and Loading the Model
