A 16-year-old developer named Afonso has detailed the year-long process of training his own 780 billion parameter language model, Ganymede 1.1. He emphasized that using a mixture-of-experts (MoE) architecture was crucial for managing compute limitations, and that data cleaning proved more time-consuming than training itself. Afonso also highlighted the importance of building safety features into the model from the outset and noted that distributed training across multiple data centers was essential for accessing the necessary GPU resources. The Ganymede 1.1 model, which features a 1 million token context window and supports tool calling, is currently available for free use via chat and an OpenAI-compatible API. AI
