About
OpenHermes 2.5 Mistral 7B is an advanced large language model developed by Teknium, building on the previous version, OpenHermes 2. Utilizing a transformer architecture, it's fine-tuned on over one million entries, combining code and non-code data, primarily composed of GPT-4 generated text. This enhances its human-like response capabilities across diverse contexts. It excels in conversational AI with its multi-turn dialogue support through the ChatML format, significantly improves in code generation tasks with a high HumanEval score, and performs robustly on benchmarks like GPT4All and AGIEval. Additionally, it offers various quantization options for optimized hardware performance and is adept at real-time data processing, making it ideal for customer service and immediate data analysis applications.
OpenHermes 2.5 Mistral 7B is an open-source model in the OpenHermes 2 family. The structured metadata tracks a 32k-token context window. This page tracks provider routes through Together AI and Fireworks AI, with the cheapest tracked route listed at $0.2 input and $0.2 output per 1M tokens. Headline tracked benchmarks include Google-Proof Q&A 38.6, HellaSwag 86.0, and HumanEval 54.8.
