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.

AIAugment Code is selling select assets, including Cosmos, Auggie CLI, and the Code Context Engine, to Harness, and the product team is moving to Harness. The company says Harness's integrated platform delivers these capabilities to customers more effectively than building them independently. Harness describes itself as building the Autonomous SDLC Platform for shipping AI-written code across enterprises.

Why it matters: The announcement shows how a coding AI company is folding its products into a larger software delivery platform, a shift that shapes how enterprise teams will buy these tools.

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.

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.

AITypeSafe AI launched Jev on September 15, a model that classifies inputs into preset outputs rather than generating text. Its founder says about 25% of Fortune Global 500 companies use it and daily token volume reached one trillion, with a reported funding round of up to $1 billion under discussion. Similar products have followed from OpenAI, Databricks, Cloudflare and Amazon.

AIPearson is acquiring Workera, a company that measures workers' skills in tasks and job roles to show businesses where employees are strong and where they need development. Andrew Ng, who served as Workera's chairman, says the combination under CEO Kian Katanforoosh and Pearson leadership could support more people and businesses.

AIOpenAI's Fidji Simo says she is excited to invest in the project and argues education needs a new model. The post offers no further detail, but the quoted background describes The Horowitz Andreessen Academy, a San Francisco school for high school graduates that raised $42M led by a16z.

AIQianjue Technology founder Gao Haichuan argues that robotics will not see one breakthrough that suddenly lifts the whole industry, and he judges the company by deployment results rather than research papers. Qianjue, founded in 2023, has completed a Series A+ round worth a nine-figure RMB sum, with first orders coming from restaurant, cleaning, and hotel service robots. Gao says customers care about task completion, failure rates, and price rather than whether a predictive world model is used.
