Qi Meng is an AI system that designs entire processor chips end to end from natural language spec to to physical layout. Their QiMeng-CPU-v1 produced a 32-bit RISC-V CPU, matching Intel 486 performance with over four million logic gates, in just five hours. QiMeng-CPU-v2, rivals an Arm Cortex A53 from the 2010s, and the whole thing runs on a domain specific model that learns the graph structures of circuits the way GPT learns text. The appeal of Qi Meng is that this open-source effort has three key interconnected layers melding LLM chip design smarts, a hardware and software design agent, and various chip design apps. The paper shows that the system can do in days what takes human teams weeks to achieve. the paper https://arxiv.org/pdf/2506.05007

The hardware efficiency gains are honestly the most interesting part of the paper. The main reason DeepSeek-V4 is so cheap to run comes down to how they completely bypassed the quadratic cost of standard attention for massive context windows. They built a hybrid attention architecture that interleaves Compressed Sparse Attention and Heavily Compressed Attention. Standard models keep every single token in the KV cache which absolutely kills memory. CSA fixes this by compressing the KV cache of multiple tokens into a single entry and then uses a sparse routing mechanism to only compute attention over the top-k most relevant compressed blocks. HCA takes it a step further by compressing an even larger number of tokens into one entry but computes dense attention over them. So, a 1.6T parameter Pro model only uses a third of the compute FLOPs and 10% of the KV cache memory compared to DeepSeek-V3.2 at a one million token context. They also aggressively pushed low-precision formats applying FP4 quantization-aware training to the Mixture-of-Experts weights and the attention Query-Key paths. MoE models are notoriously memory bound because you have to constantly shuttle massive expert weights into the GPU cores. Dropping these to FP4 slashes the memory bandwidth bottleneck and lets the model run way faster during inference without ruining accuracy since they handle the quantization dynamically during training. On the infrastructure side they wrote a custom fused kernel using TileLang that overlaps communication and computation. When running expert parallelism across multiple GPUs you usually hit a wall waiting for the network. DeepSeek slices the experts into micro-waves so the GPU is crunching matrix math on the first wave while the network is simultaneously pulling the data for the second wave. They basically hid the network latency behind the compute time which means you do not need super expensive interconnects to get peak hardware utilization out of the cluster.

You type any topic, and it renders a clickable, sometimes animated image explaining it — similar to prompting ChatGPT or Claude, but the output is visual rather than text. According to [LinkedIn](https://www.linkedin.com/posts/dan-zinkin_flipbook-the-infinite-visual-browser-flipbook-activity-7453062289869533184-1ESi), the tool was built by Zain Shah and team. It describes itself as "an infinite visual browser generated entirely on demand in real time."

A directory created by the Centers for Medicare and Medicaid Services (CMS) has exposed the Social Security numbers of a number of US healthcare providers. The Trump administration introduced a new Medicare portal as part of plans to modernize US healthcare technology. However, a database that was part of the directory was left publicly accessible, and exposed providers’ names and Social Security numbers.

Self-styled free speech warrior Elon Musk’s X (Twitter) banned me after I published a copy of the Donald Trump campaign’s JD Vance research dossier. X says that I’ve been suspended for “violating our rules against posting private information,” citing a tweet linking to my story about the JD Vance dossier. First, I never published any private information on X. I linked to an article I wrote here, linking to a document of controversial provenance, one that I didn’t want to alter for that very reason. On the one hand, this is a very funny end to my Twitter journey. On the other hand, I no longer have access to the primary channel by which I disseminate primarily news (and shitposts of course) to the general public. This chilling effect on speech is exactly why we published the Vance Dossier in its entirety. **Not a single media organization was willing to publish a document that would have been a no-brainer during or prior to the heyday of Edward Snowden’s disclosures. That illustrates the dramatic shift in attitudes about what the news media thinks the public should know**, and the role the mainstream plays in steadily ceding that territory to the national security threat machine. Media’s job, I believe, is to push back against these various forms of censorship. I’ll keep doing that here on this newsletter, where you can find me going forward. If you agree with what I laid out, I hope you’ll subscribe.
