Every statement that passed quotation and attribution checks. Mix any filter with any other: certainty 1/5, debate potential 5/5, or both at once.
why aren't all 2 resolved? a statement only gets an assessment when the public record can support or contradict it. opinions and what-ifs never can, and 0 checkable ones are still open, waiting for their date. predictions held up or didn't; assertions are supported or contradicted. on every card: ▮▮▮▮▮ certainty · ▮▮▮▮▮ debate potential. speakers are clickable
Quantization, speculative decoding, and prefill-decode disaggregation each yield 2x speedups
“Going from BF-sixteen to NVFP four is, it's not quite a two X, right? It's like, I think it's about like 30, 30 to 40% from 16 to eight, and then another 30 to 40% multiplied from eight to four. So that doesn't quite get you a two X, but like roughly a two X. …”
TurboQuant is inefficient on high-bandwidth data center GPUs like NVIDIA B200
“TurboQuant would not be like, it would not be used. Like Nvidia made it clear that this is not a good optimization. And we've seen it firsthand where the overhead of doing dequantization, quantization of You know, in the kernel itself, the turbo-quant kernel, …”
