10 Things That Matter in AI Right Now technologyreview.com

LLMs+ technologyreview.com

When ChatGPT launched as an experimental prototype in late 2022, OpenAI’s chatbot became an everyday everything app for hundreds of millions of people. LLMs like ChatGPT were the new future: The entire tech industry was consumed by the inferno, with companies racing to spin up rival products. The ashes of the old tech world still…

Supercharged scams technologyreview.com

When ChatGPT was released to the public in late 2022, it opened people’s eyes to how easily generative AI could churn out vast amounts of human-seeming text from simple prompts. This quickly caught the attention of criminals, who soon began using large language models to produce malicious emails—both the untargeted spam kind and more sophisticated,…

World models technologyreview.com

AI systems have already gained impressive mastery over the digital world, but the physical world is still humanity’s domain. As it turns out, building an AI system that can compose a novel or code an app is far easier than developing one that can fold laundry or navigate a city street. To get there, many…

Weaponized deepfakes technologyreview.com

For years, experts have warned that deepfakes—AI-generated videos, images, or audio recordings of people doing or saying things they haven’t actually done in real life—could be deployed in malicious ways. These dangers are now here. Improvements in deepfake technology, and the widespread availability of easy-to-use and cheap (or free) generative models, have made it easier…

the UK AI Safety Institute discovered a ‘universal jailbreak’ that bypassed safety filters across all malicious cyber queries in just six hours of expert red-teaming… if a government body like AISI identifies a critical vulnerability, developers should have a legal obligation to delay release.

Tom’s Hardware tomshardware.com

Google’s TPU 8t delivers approximately 12.6 FP4 PFLOPs per socket, still trailing NVIDIA’s Vera Rubin (35 PFLOPs) and AMD’s MI455X (40 PFLOPs) by a ratio of roughly 3:1… Google’s decision to use HBM3e instead of HBM4 for the 8t resulted in an 11.5% reduction in memory bandwidth compared to theoretical targets — a trade-off likely made to improve manufacturing yields and lower costs.

Hyperframe Research hyperframeresearch.com

Google claims a 97% ‘goodput’ (actual training efficiency)… these assertions are currently ‘the hardest to independently verify’ until production workloads are deployed.

TheElec thelec.net

Broadcom remains the primary partner for the high-performance TPU 8t, while MediaTek has been brought in to co-design the TPU 8i… ending Broadcom’s decade-long exclusivity in the TPU program and potentially reducing per-chip costs by up to 30%.

Nand Research nand-research.com

The TPU 8i triples on-chip SRAM to 384 MB and doubles interconnect bandwidth to 19.2 Tb/s, allowing the chip to host large KV Caches directly on silicon, drastically reducing the latency of agentic workflows.
