Artificial intelligence startup Hugging Face recently announced that its H4 team, consisting of two members, is dedicated to developing tools and "recipes" to assist the AI community in building AI chatbots similar to ChatGPT. H4 has released multiple large-scale open-source language models, including the recently launched chat-specific model Zephyr-7B-α. The team plans to release a manual this month, disclosing the full code and dataset used to build Zephyr. Supported by Hugging Face's internal team and relying on GPU clusters for model training, H4 intends to continue updating the manual with the release of future AI models.
