Introducing Openhermes 2.5: Comprehending the Power of Messenger of Gods
Introduction
Welcome to our exploration of OpenHermes 2.5, a groundbreaking dataset developed by Teknium. This blog dives into the features, applications, and advancements of this state-of-the-art model extension.
What Is Openhermes 2.5?
Basic Background of Openhermes 2.5
Developed by Teknium, Openhermes 2.5 is an extension and an improvement of the Open Hermes 1 dataset. It is characterized by a much larger scale, greater diversity, and higher quality, with a compilation of over 1 million synthetically generated instruction and chat samples.
Key Features of Openhermes 2.5
- It is a compilation of various open source datasets and custom-created synthetic datasets.
- The dataset has been integrated with Lilac, a data curation and exploration platform, and is available on HuggingFace for exploration, curation, and text embedding searches.
- Openhermes 2.5 includes contributions from multiple sources, such as Airoboros 2.2, CamelAI Domain Expert Datasets, ChatBot Arena, Collective Cognition, and others, each providing a unique set of data that enriches the overall dataset.
- The structure of Openhermes 2.5 follows a sharegpt format, which is a list of dictionaries. Each entry includes a “conversations” list with dictionaries for each turn, indicating the role (e.g., “system”, “human”, “gpt”) and the text value of the conversation.
Dataset Sources of OpenHermes 2.5
OpenHermes 2.5 incorporates data from a wide range of sources, each contributing to the dataset’s comprehensiveness and utility in training LLMs. Some notable sources include:
- Airoboros 2.2: A dataset by Jon Durbin.
- CamelAI Domain Expert Datasets: Covering Physics, Math, Chemistry, and Biology.
- ChatBot Arena: A GPT-4 specific dataset.
- Collective Cognition: A dataset by Teknium.

What Is OpenHermes-2.5-Mistral-7B?
Explanation
- Continuation of OpenHermes 2: OpenHermes 2.5 Mistral 7B is a state of the art Mistral Fine-tune. It builds upon the previous OpenHermes 2 model, indicating a progression in its development and capabilities.
- Training on Code Datasets: A significant portion of the training data (an estimated 7–14% of the total dataset) consists of code instructions. This training on code has had a positive impact on the model’s performance.
- Training Data: OpenHermes 2.5 was trained on 1 million entries, primarily generated by GPT-4, along with other high-quality data from various open datasets across the AI landscape. This diverse training data likely contributes to the model’s broad capabilities.
- Data Filtering and Format Conversion: Extensive filtering was applied to the public datasets used for training. All data formats were converted to ShareGPT, which was then further transformed by axolotl to use ChatML. This process of standardization and transformation ensures consistency in the training data and may contribute to the model’s improved performance.
Benchmark Performances of OpenHermes-2.5-Mistral-7B
- TruthfulQA, AGIEval, and GPT4All Suite: The model has seen a boost in performance on these non-code benchmarks, suggesting that training on code datasets has generalized well to other areas.
- BigBench: Interestingly, while the model’s score on the BigBench benchmark decreased, the overall net gain in performance across other benchmarks is still significant, indicating an improvement in the model’s capabilities.
- Humaneval Score Improvement: The model’s performance on the humaneval benchmark, which measures the model’s ability to perform human-like evaluations, has improved from 43% at Pass 1 with Open Hermes 2 to 50.7% at Pass 1 with OpenHermes 2.5. This is a substantial increase and reflects the model’s enhanced ability to generate more human-like responses.
