Hermes 3

Hermes 3 is an open-source large language model developed by Nous Research for developers, researchers, and businesses building AI-powered applications. Based on Llama architectures, it is optimized for natural conversations, coding assistance, reasoning, instruction following, and agent-based workflows. The model supports function calling, structured outputs, long-context understanding, and multilingual interactions, making it suitable for AI assistants, automation tools, and software development. Since it is openly available, users can fine-tune and deploy it on their own infrastructure without relying on proprietary services. Hermes 3 is especially useful for teams that need a capable language model while maintaining flexibility, customization, and control over deployment.
