Claude Fable Five Built a model with one prompt. It's fully open sourced (github.com)

Claude Fable Five has introduced GlassBox, an innovative language model that is fully open-sourced and made accessible through a single HTML file that runs directly in the browser. Uniquely, this model, developed purely in NumPy without reliance on frameworks like PyTorch, allows users to see every computation involved in generating text, from attention distributions to probability calculations. It boasts 628,161 parameters, enabling it to produce Shakespeare-like dialogue almost instantly upon loading, making it an engaging tool for both technical and non-technical users alike. This release is significant for the AI/ML community as it emphasizes transparency in machine learning models, providing an educational platform for those looking to understand the inner workings of language models. By training in about 30-45 minutes on standard laptop hardware, GlassBox democratizes access to AI, encouraging experimentation with any UTF-8 text. The project underscores a shift towards smaller, more interpretable models while maintaining the integrity of larger architectures, and it promotes the idea that fine-tuning and training can be accessible to a wider audience. The model's straightforward design and the ability to run offline serve to future-proof it against potential outages in API-based services.
