The BitNet b1.58 2B4T Technical Report discusses a new model that packs weights into an int8 format, thus storing 4 weights per integer but sub-optimally at 2 bits per weight instead of the theoretical minimum of approximately 1.58 bits. While the report pushes advancements in model parameters and their efficiency, there are inquiries about the practical implications of this storage method. Users are keen to understand how these models can be utilized effectively in production settings, especially concerning fine-tuning for high-performance results, with some hoping to achieve accuracy in the range of 95-99%. There is an overall interest in exploring the potential applications of 2B models across various tasks, suggesting they might serve well in real-world scenarios but requiring further exploration into their capabilities and optimizations.
