Nvidia, Intel and ARM have published a draft specification for a common AI interchange format aimed at faster and more efficient system development. The proposed “8-bit floating point” standard, known as FP8, will potentially accelerate both training and operating the systems by reducing memory usage and optimizing interconnect bandwidth. The lower precision number format is a key factor in driving efficiency. Transformer networks, in particular, benefit from an 8-bit floating point precision, and having a common interchange format should facilitate interoperability advances for both hardware and software platforms.

Ethereum developers prepared with diligence and attention to detail, but the industry was still on pins and needles as engineers scanned for snags and, though unlikely, braced for the possibility of systemwide collapse. Huge in scale, it was a high-wire act transitioning a live network. Read more

Executives from four social media giants defended the privacy, security and content moderation protocols of their platforms to the Senate Homeland Security Committee Wednesday.

ByteDance, which owns TikTok, is based in Beijing, and its potential censorship of user content was another area of concern. Questions for the group — which included representatives from Meta Platforms, YouTube and Twitter — ranged from extremists to biometrics. Read more
