BitNet: Inference framework for 1-bit LLMs
“I don't see the news here ... there's which is last updated 12/2025 ... am I just paying more attention here or is there something actually new about this? Also as far as I know, this is more of a research curiosity - BitNet really doesn't perform that well on evals. I think…”

Microsoft BitNet: inference framework for 1-bit LLMs
“I'm enthusiastic about BitNet and the potential of low-bit LLMs - the papers show impressive perplexity scores matching full-precision models while drastically reducing compute and memory requirements. What's puzzling is we're not seeing any major providers announce plans to…”
