AIGeekPark reports that Krinwave, a Shenzhen company, has completed a new 400 million yuan round with XVC and Sequoia China as new investors. The company says its low-frequency ultrasound captures brain structures through the skull, which conventional high-frequency devices cannot, and it aims to supply hardware and its kOS software platform to brain-computer interface and NeuroAI groups.

AIThreatBook has acquired CyberStrikeAI, an open-source AI pentesting agent, after reports that attackers had used it in real intrusions. The company says it added guardrails to limit misuse but will put new capability enhancements into its commercial edition, and it argues defenders should control such tools. It also corrects an earlier threat intelligence report that linked the developer, a security engineer at Alipay, to government agencies, calling that attribution a false positive.

AINaive AI, a Tsinghua-linked company founded seven months ago, has raised $400 million across three rounds at a post-money valuation of $1.42 billion. The company's founder is Dai Jifeng, an associate professor in Tsinghua's Department of Electronic Engineering, and its team has not given interviews or published a product introduction.

AIGallatin AI raised $50 million in a Series A round led by contributors including 8VC and Silent Ventures, following a $15 million seed raise in 2024. The El Segundo, California company's Navigator platform helps the U.S. military manage supply chains, with the U.S. Army and U.S. Air Force listed as customers. Gallatin says it will use the funds to enhance Navigator's AI capabilities and hire more engineers.

AIZach Yadegari, the teen co-founder of calorie tracking app Cal AI, has launched Persona, a personal AI assistant startup that has raised $10 million led by Vine Ventures. Persona will offer a $179 wearable band that activates via button or wrist flick, with the model running in the cloud rather than on the device. The band is expected in December, and Persona is currently a free beta available through iMessage.

AISafeWorld emerged from stealth this week with $12.2 million in seed funding for its robot safety simulation platform. The software lets teams build test scenarios from past incidents, safety standards, and robot logs, then runs robots through thousands of variations with reactive human motion. SafeWorld said it supports robot arms, humanoids, and mobile robots, with customers in industrial, manufacturing, logistics, and construction.

AIHelm.ai said it signed $70 million in commercial contracts for its foundation models for physical AI over 12 months, spanning global automotive OEMs, Tier 1 suppliers, and industrial automation companies. The Redwood City, Calif.-based company said it has projects bound for production in autonomous vehicles, mining, and construction, and that it is on a path to break even. CEO Vladislav Voroninski said its models are trained on unsupervised "deep teaching" and are environment-agnostic.

AIArchitect Financial Technologies has launched Liquid Inference, an LLM router that auctions each request to providers quoting the requested model, and the lowest qualifying offer wins. Buyers can set per-job cost caps, time-to-first-token limits, minimum throughput, and region or zero-data-retention rules, and the max price is locked before generation. The source states that fees, provider list, and latency data are not yet public.

AIPreference Model is open-sourcing Karotte, the framework it uses to build reinforcement learning environments that resist reward hacking, including defenses like killing stray processes before grading and rejecting grader-crashing files. The framework has been hardened through more than a million evaluation runs and controlled red-teaming. The company focuses on machine learning engineering tasks for leading labs, and a16z says it is partnering with Preference Model and its founders, Jennifer Zhou and Ning Cao.

AIGeneral Medicine raised a $120M Series B led by a16z to build a consumer healthcare marketplace. The company combines patient history, clinical guidance, transparent pricing and access to care in one experience, with a catalog of over 2,900 products and services across medications, labs, imaging and specialist consultations. It is also offering the same infrastructure to health systems, payors and pharmacies.

AIAI Studio Authors First has launched with $10 million in backing and pledges to help writers faithfully adapt their books. The company positions its tools as a way to keep authors in control of how their work is translated to screen. The post links to a Variety report with further details.

AISemiAnalysis measured usage meters on Anthropic and OpenAI subscription plans to estimate each plan's API-equivalent value. At mid-tier models, it found Anthropic offers roughly 5x the value of OpenAI, after OpenAI halved its $200 plan limits and introduced a $500 tier. The analysis also argues that subscriptions take a large share of inference compute while providing a small share of revenue, so their limits materially affect lab margins.

AIswyx says Flow is doing for hardware engineering what Git and GitHub did for software, aligning thousands of stakeholders on complex, irreversible, high-value pipelines from cars to rockets. The background post says Flow raised a $50M Series B at a $750M valuation and is now used for requirements and verification by Anduril, Joby, Stoke Space, Rivian, and General Motors PPU, among others. It argues AI agents will soon move from integrating hardware engineering work to doing it.

AILong Lake, founded three years ago, has completed its $6.3B acquisition of Amex GBT, its 40th acquisition. The company says its family of businesses now employs nearly 30,000 people and aims to help businesses deploy AI to improve customer service.

AISemiAnalysis releases ClusterMAX 3.0, a rating of managed GPU clusters from neoclouds that covers 77 providers, with 323 in its market view. The rating is based on audit, performance, and reliability tests, along with interviews with over 200 end users. CoreWeave and Nebius hold the Platinum tier, Google Cloud and Oracle hold Gold, and only 19 providers earned a Medallion rating.

Why it matters: The report shows how GPU cloud providers are ranked through hands-on tests, with details on benchmarks, reliability checks and SLA terms that buyers can reuse.
