X Platform July 24 AI Brief | Chinese Mathematicians Win First Fields Medal, Huang Renxun and Tech Giants Back Open-Source AI, FLUX 3 Unifies Multimodal Generation

Wang Hong and Deng Yu Win Fields Medal: Chinese Mathematicians Secure Mathematics’ Highest Honor for the First Time

The 2026 Fields Medal winners have been announced, with Peking University alumni Wang Hong and Deng Yu becoming the first Chinese recipients, sparking widespread discussion in the Chinese X community. French President Emmanuel Macron and official channels like École Polytechnique have issued congratulations. Netizens noted that Wang Hong uses the anime character Mikumo from “Skip and Loafer” as her profile picture, while Deng Yu uses Saeki Sayaka from “Bloom Into You.” Many bloggers remarked on both mathematicians using anime avatars, joking that “anime has won.” A blogger compiled Deng Yu’s past quotes, with his classic question, “What are some excellent yuri (girls’ love) fan works?” also circulating online.

Jensen Huang Joins X, Co-signs Open Letter with Tech Giants to Support Open-Source AI Ecosystem

NVIDIA CEO Jensen Huang made his first post on X, sharing an open letter jointly signed by companies including NVIDIA, Palantir, Replit, Microsoft, Crowdstrike, and Dell. The letter emphasizes the critical role of open-weight AI models for U.S. leadership in AI. Huang argues in the letter that the U.S. should not equate AI leadership with protecting a few leading companies but should win the competition through open models, computing infrastructure, and broad ecosystem adoption. Elon Musk publicly expressed “full support”; Microsoft CEO Satya Nadella and Sam Altman also echoed the sentiment. This move is seen as the first clear stance by top CEOs in the U.S. tech industry supporting an open ecosystem, amid government discussions on potentially restricting Chinese open-source models.

FLUX 3 Officially Released: A World Model Unifying Image, Video, Audio, and Motion Prediction

Black Forest Labs has released FLUX 3, based on its proprietary Self-Flow architecture. It uses a single multimodal flow matching architecture to jointly train on images, video, and audio, and extends the same backbone to motion prediction. FLUX 3 can generate videos up to 20 seconds long with native audio in a single pass, supporting text-to-video, image-to-video, video inpainting, and keyframe control. BFL, in collaboration with mimic robotics, has launched FLUX-mimic based on FLUX 3, which has been tested in real Audi production environments. Some robot operation tasks require only about 30 minutes of robot data for fine-tuning. BFL plans to release the open-weight FLUX 3 Dev later this year.

Cognition Acquires Poke: Devin Enters the Era of Always-On General-Purpose Agents

AI programming agent company Cognition announced the acquisition of the consumer AI Agent product Poke (developer: Interaction). Poke’s core entry point is instant messaging apps (Apple Messages, Telegram, WhatsApp). Users interact with it like a real human assistant; it proactively contacts users, follows up on task progress, and calls tools at appropriate times. Before the acquisition, the Interaction team had only about 10 people, with cumulative funding of approximately $25 million and a valuation reaching $300 million. Post-acquisition, Devin (for engineering tasks) and Poke (for daily interaction) complement each other, jointly advancing the vision of always-on, memory-capable, proactively communicative, and continuously task-executing general-purpose agents.

Anthropic Invests Another $20 Million in AI Regulation Lobbying, Escalating Tech Giant Political Games

Anthropic has donated another $20 million to the political action organization Public First Action, bringing its total investment to $40 million. This organization advocates for stricter regulation of frontier AI. Its counterpart, Leading the Future, is supported by OpenAI President Greg Brockman, Marc Andreessen, and Ben Horowitz, among others, and advocates for accelerating AI development and opposing premature strict regulation. Several bloggers point out that competition among AI companies has extended from models, talent, and computing power to influencing U.S. legislation and midterm elections. Meanwhile, Meta has launched an AI optimism campaign, with Mark Zuckerberg publicly countering the narrative that AI causes mass unemployment; NVIDIA and xAI also emphasize openness, accessibility, and productivity, showing a clear factional split in the industry over AI regulation direction.

OpenAI Launches GPT-Live Voice Desktop Control and Multiple Codex Updates

OpenAI has added voice control functionality to the ChatGPT desktop app (formerly Codex App). Based on the GPT-Live full-duplex architecture, users on macOS and Windows can control their computers and launch Codex for coding via voice, without typing. macOS users gain a new Appshots feature, where the AI can view the content of the active window during a voice conversation to provide contextual responses. Several bloggers who tested it praised the smooth experience, considering it a milestone for Vibe Coding entering a pure voice interaction phase. Additionally, ChatGPT’s new Sites feature for one-click website building has also attracted attention from some bloggers.

AI Chip Company Etched Completes $300 Million Series C Funding, Valuation Exceeds $10 Billion

AI chip company Etched has completed a $300 million Series C funding round, valuing the company at $10.3 billion. The round was led by Sequoia Capital, with participation from a16z, Jane Street, SK Hynix, and others. Just three weeks ago, Etched announced that its first-generation chip had returned from TSMC’s N4P process and secured over $1 billion in customer contracts, despite the product not yet being in mass production. The company is betting that the Transformer architecture will continue to dominate AI, delivering not just a single ASIC chip but a complete inference cluster solution encompassing chip, packaging, PCB, liquid cooling, and software co-design. Founded in 2022 by three Harvard dropouts, the company operates in an increasingly fierce system-level competition for inference computing power.

Claude Opus 5 Showcases Impressive 3D Capabilities, Multiple AI Security Incidents Continue to Unfold

Several bloggers are focusing on the yet-to-be-officially-released Claude Opus 5: testers can generate a fully functional web scene with complete 3D structure, materials, lighting, and interactivity from a single prompt, with evaluations surpassing Fable 5, GPT-5.6 Sol, and Kimi K3. On the security front, the Anthropic Cowork sandbox was disclosed to have a SharedRoot vulnerability, allowing attackers to exploit a Linux kernel vulnerability to escape the virtual machine and access the host file system. NVIDIA released the JEPA-DNA genome foundation model, introducing the Joint Embedding Predictive Architecture to genomics, outperforming previous best models on multiple tasks. The Doubao large model was found pre-installed in the infotainment system of newly delivered Tesla vehicles, currently supporting only basic functions.
