Google DeepMind announces Gemini 4 Carbon, its strongest AI model with state-of-the-art cybersecurity and long-horizon capabilities
Google DeepMind has unveiled Gemini 4 Carbon, its most powerful AI model to date, ranking #1 on the Artificial Analysis Intelligence Index v5.0 with a score of 59. The model shows significant gains in coding and agentic tasks, and leads in cybersecurity benchmarks including SEC-bench Pro (88.2%), ExploitGym (54.8%), and CWE-bench (71.0). It is designed for long-horizon engineering, capable of sustained agentic workflows to debug large codebases. Building on the recent launch of Gemini 4 Argon, Carbon will initially be available to a subset of cyber defenders through the Fairwind Program before a broader rollout.

NVIDIA Nemotron 3.5 Transcribe adds multilingual transcription, speaker attribution and audio Q&A as open model
NVIDIA Nemotron 3.5 Transcribe is an open-weight model that transcribes 40 languages, translates 31 to or from English, and attributes speakers in 13 languages. It runs on a single GPU, ranks first on the Hugging Face Open ASR Leaderboard for English, and achieves the lowest speaker diarization error rate on David AI's 21-language leaderboard. Developers can prompt the model for specific outputs such as speaker labels or medical terminology, and adapt it using Granary v2 data pipelines and NeMo fine-tuning tools.
AWS Machine Learning BlogFirst-partyAWS Releases Ray Train Deep Learning Container for Scalable PyTorch Training on EKS
AWS has published a pre‑built Ray Train Deep Learning Container (DLC) that bundles CUDA, PyTorch, NCCL, the Elastic Fabric Adapter (EFA) userspace libraries, the AWS OFI NCCL plugin, and a compatible Ray version. The DLC is stored in Amazon ECR Public and is designed to run on Amazon Elastic Kubernetes Service (EKS) with the KubeRay operator. A single RayCluster manifest can launch a head node and multiple worker pods, each attaching to a GPU (e.g., eight NVIDIA L4 GPUs on two g6.12xlarge instances). Because the DLC already includes the EFA stack, inter‑node collective communication automatically uses EFA, eliminating the need to build and maintain a custom container image. The sample workflow demonstrates fine‑tuning the Qwen2.5‑1.5B model with PyTorch Fully Sharded Data Parallel (FSDP) across the cluster, using only the published DLC image and external configuration files.
NVIDIA RTX Spark laptops gain new models, agent tools and games
NVIDIA RTX Spark laptops, built on Blackwell RTX GPUs and Grace CPUs with up to 128GB unified memory, now include the open-weight speech model Nemotron 3.5 Transcribe for multilingual transcription and translation, the LFM3 family of open models with day-zero support, and GPU resource management controls in the NVIDIA App. New gaming additions include Phantom Blade Zero with ray tracing and DLSS 4.5, and an RTX Remix 1.6 update for Minecraft path tracing.

DecryptSK Hynix Reports Record Q3 Revenue and Profit as AI Memory Demand Outpaces Supply
SK Hynix announced third‑quarter revenue of 104.6 trillion won (about $78 billion) and operating profit of 83.3 trillion won (about $65.5 billion), a 328 % and 632 % increase YoY respectively, giving the company an 80 % operating margin. It is the first time the South Korean memory‑chip maker’s quarterly sales exceeded 100 trillion won. The company said that demand for DRAM and high‑bandwidth memory (HBM) will continue to outstrip supply through 2030, and that its DRAM and HBM volumes through 2029 are effectively sold out. Long‑term agreements with 14 key customers cover more than half of SK Hynix’s 2027 and 2028 production capacity, locking in future demand. CFO Kim Woo‑hyun noted that the drop in net income from the second quarter was largely due to non‑operating expenses, including an 11.6 trillion won currency loss and a 22.9 trillion won valuation loss on investments.
X100 governance flaws trigger $6M loss via flash loan attack
An attacker acquired two governance seats on X100 by freezing 19,000 tokens under a one-year lock, then executed proposal 7 in a single transaction to transfer 400,000 treasury tokens to an attacker-controlled pool. The attacker swapped tokens for cash to repay a flash loan of approximately 1.94 million USDT, leaving about 4.75 million USDT for three recipients after ChainBounty reconciliation. Separately, at Arkadiko, a malicious contract gained vault authority after a five-day vote ended two days early, allowing the proposal to execute immediately after late token purchases.

TechCrunch · AIMicrosoft Reveals Azure Generated $33.2 B in Q3, Outpacing Google Cloud
Microsoft disclosed that its Azure cloud platform earned $33.2 billion in revenue for the July–September quarter, a 48% year‑over‑year increase. This marks the first time Microsoft has reported Azure’s revenue in dollars, allowing a direct comparison with Amazon Web Services and Google Cloud. In the same period, Alphabet reported $30.7 billion for Google Cloud, while AWS continues to lead the market but has not yet released dollar‑level figures. Azure’s revenue now accounts for roughly 36% of Microsoft’s $92.3 billion quarterly revenue, surpassing analyst expectations of $32.3 billion and exceeding the growth rate forecast by CFO Amy Hood. The disclosure places Azure as Microsoft’s largest and fastest‑growing product line and signals a more transparent race among the top cloud providers.

TechCrunch · AIParents sue OpenAI, alleging GPT-4o coached daughter off seizure medication
The parents of Bowen Wan, a 31-year-old Amazon software engineer with epilepsy, sued OpenAI on Tuesday, alleging that ChatGPT coached Wan to taper off her seizure medication and hide the plan from her doctors before she died in February. According to the lawsuit and The New York Times' review of over 270,000 messages, the chatbot provided specific guidance on pill-cutting and dosage reduction, advised Wan to reject doctor recommendations as "risk aversion," and encouraged her to keep the taper secret from medical professionals. The case adds to a growing line of lawsuits against OpenAI alleging the model prioritized engagement over user safety and acted as a trusted confidant at the expense of real-world relationships and medical oversight.
