    Export-banned Nvidia chips are behind China’s most powerful AI models — uh-oh, Jensen!

    Unemployment Labs researcher Will DePue analyzed the weights of openly released models from DeepSeek, Moonshot AI, MiniMax and Ant Group and found evidence that models including Moonshot's Kimi K3 releases and DeepSeek's V4 bear fingerprints of training on export-banned Blackwell chips. Epoch AI estimates about two million advanced chips entered China in 2024 and 2025 through schemes hiding their final destination, though the chips could have been in offshore data centers such as those in Malaysia, which imported an estimated 275,000 Nvidia AI accelerators in that period. The article also reports that Nvidia CEO Jensen Huang left the company this week after admitting an affair with Alice Huang, an executive of Megaspeed, a company implicated in smuggling Nvidia chips into China.

    Why it matters: The piece is useful for readers tracking how researchers infer training hardware from model weights and how export-control debates are colliding with Nvidia's corporate and leadership turmoil.

    DeepSeek-V4.1-Flash on Vera Rubin NVL72: 58x Throughput vs. GB300 NVL72 at 387 tokens/s

    On a single NVIDIA Vera Rubin NVL72 rack, vLLM serves DeepSeek-V4.1-Flash at 1.7M tokens/s per GPU with 387 tokens/s per user, 58x GB300 NVL72, reaching 2.52M at peak throughput and 1,810 tokens/s for a single user. The gains come from kernels tuned for Rubin's split memory domains and FP4 tensor cores, specialized low-latency decode kernels, and a rack-wide KV cache and Engram tables shared over NVLink. The post details four optimization groups and reports a 96.5–97% prefix hit rate at high concurrency with workload-aware routing.

    Why it matters: It offers a detailed, measurement-backed look at how Rubin-specific memory and MMA features translate into serving throughput and latency for a frontier open model.

    Chinese frontier AI models carry the fingerprint of export-controlled GPUs

    A forensic analysis of published model weights finds that six models from DeepSeek, Moonshot AI, MiniMax and Ant Group, released between April and November 2026, contain numerical patterns matching NVIDIA Blackwell chips (148-SM B200/B300 or 152-SM GB200/GB300), while earlier models from the same labs match Hopper. The authors recovered initialization seeds and thread layouts from preserved weights and confirmed the match on physical Blackwell hardware for DeepSeek-V4-Flash and Kimi K3, estimating each training run used roughly 500 to 3,000 GPUs. The report says the evidence shows access to export-controlled hardware but does not establish where the chips were located, how access was obtained, or whether export controls were violated.

    Why it matters: It offers a detailed, reproducible method for inferring training hardware from model weights, with explicit caveats about what the fingerprints do and do not prove.

    Phala Confidential AI Compromised

    Phala published preliminary findings on a security incident in which an attacker chained a legacy internet-facing service with management interfaces that trusted loopback access, creating unauthorized CVMs and obtaining application credentials, and also took control of an inference VM serving DeepSeek V4 Flash 0731, exposing in-flight request data. Requests routed to Phala by OpenRouter between October 21, 2026 00:00 UTC and November 8, 2026 05:35 UTC should be treated as exposed, and affected CVM owners were contacted directly with rotation guidance. Phala contained the incident on November 8, rotated its KMS root key on November 6, restored the model service with added protections, and says a full root cause analysis is still in progress.

    Why it matters: The report gives a detailed operational timeline and concrete credential-rotation guidance for users of a confidential AI provider, useful for anyone assessing exposure or third-party AI infrastructure risk.

    AI agents stole 190k gaming credentials for under $400 in model costs

    Check Point Research analyzed operator-console artifacts from 10 misconfigured ARTEX agentic hacking instances, finding attacks ran almost fully autonomously with Chinese models, especially DeepSeek Flash, dominating usage. One operator's fleet recovered over 190,000 Honor of Kings credential sets (about 3.3% still valid) for an estimated $180–$360 in model costs, while another spent roughly $700–$1,500 over two weeks to obtain more than 300 iOS code-signing certificates. Researchers counted 2,557 systems hosting ARTEX panels, 1,608 of them live and public, and observed agents chaining RCE, IDOR and SSTI flaws into supply chain compromises.

    Why it matters: It offers rare operator-side evidence of how cheaply and autonomously LLM agent fleets now conduct opportunistic cybercrime at scale.

    Zero Mismatch, Simple Async RL: REINFORCE Zero, DeepSeek-V4.1 and Kimi K3.1

    The post argues that asynchronous RL's rollout-to-learner logprob gap splits into smoothly varying weight lag, which unclipped importance sampling can correct, and fluctuating kernel mismatch, which persists despite IS; aligning kernels first lets REINFORCE Zero train stably for 20,000 updates, learn at policy lag 64, and reach 2.40× the training-step throughput of synchronous training with aligned kernels. It reports zero mismatch (bit-for-bit logprob agreement) for DeepSeek-V4.1-Flash and Kimi K3.1 on day 0, and for DeepSeek-V4-Flash and Kimi K3.1 on AMD MI355X. Code and recipes are in Inferact/zero-mismatch-rl, with the paper at hijkzzz/REINFORCE-Zero and training code in NVIDIA-NeMo/labs-molt.

    Why it matters: It offers a concrete diagnosis of why async RL drifts and a minimal recipe, backed by throughput, lag-64 and cross-vendor alignment results.

    [AINews] DeepSeek DeepInfer: Open Source SOTA Inference running 155T toks/day/cluster making $22m/day at ~80% margin for a 81 day payback

    DeepSeek released DeepInfer, its production inference stack built on vLLM with speculative decoding, SWA Bounded Replay and structured output, reporting 155 trillion tokens/day from one cluster, 96% input-cache hits, 400 ms average time to first token and $38 revenue per accelerator-hour at off-peak prices. The release excludes KV-cache management and load balancing, which remain coupled to internal infrastructure, and vLLM reported decode throughput within 6% of DeepInfer's published results on GB200 under a matched configuration. Community margin estimates of roughly 80% depend on a cache-heavy token mix and omit costs such as SSD cache, networking and idle capacity, so the figures are first-party production claims rather than audited measurements.

    Why it matters: Useful for readers tracking open-source inference economics, since it pairs DeepSeek's production claims with vLLM's comparative benchmark and a careful accounting of what the margin figures do and do not include.
