xAI sues ex-engineer for trade secret theft

PLUS: AI stethoscope spots hidden heart problems

Good morning, AI enthusiasts. Elon Musk’s xAI has made headlines suing OpenAI, Microsoft, Apple, and half of Silicon Valley… But its latest lawsuit hits closer to home.

The company is now suing a former engineer who allegedly downloaded Grok's secrets, sold his equity, and was set to walk straight into OpenAI's arms — making for a dark turn in the increasingly cutthroat AI talent wars.

In today’s AI rundown:

  • xAI sues ex-engineer over trade secret theft

  • Meta’s superintelligence team faces departures

  • Create designs with Genspark AI Designer

  • AI stethoscope spots hidden heart problems

  • 4 new AI tools, community workflows, and more

LATEST DEVELOPMENTS

XAI

The Rundown: Elon Musk's xAI just filed a lawsuit against former engineer Xuechen Li, accusing him of allegedly stealing Grok trade secrets days before selling millions of dollars in equity and resigning to join OpenAI.

The details:

  • Li accepted an OAI position in July that was set to start in mid-August, selling $7M in xAI stock and resigning from the company shortly after.

  • xAI said Li stole “cutting-edge AI tech with features superior to those offered by ChatGPT,” downloading confidential trade secrets to his personal devices.

  • xAI claims Li admitted to stealing the data during a meeting with the company on Aug. 14, while also trying to cover tracks by deleting logs and renaming files.

  • Li joined xAI in 2024 as one of the first 20 engineers at the company, working on developing and training its Grok language model.

  • xAI is seeking an injunction to block Li from working at OpenAI and any other competitor while the case is outstanding, alongside monetary damages.

Why it matters: The AI talent wars are out of control, and so is the temptation to monetize insider knowledge, with engineers carrying billions in IP both in their heads and on their laptops. The fact that this also involves an xAI to OpenAI move will likely only deepen tensions between Elon Musk and his former company.

META

The Rundown: Meta’s high-profile Superintelligence Labs team is facing a series of early departures and reported turmoil in its relationship with data provider Scale AI, hinting at a chaotic start for the new division after a summer of major overhauls.

The details:

  • Shengjia Zhao reportedly threatened to quit days after joining MSL, set on returning to OpenAI before eventually being given the chief scientist title.

  • Meta researchers view Scale AI's data as inferior, according to TechCrunch, opting for competitors despite the $14.3B investment in Wang's company.

  • Several of Meta’s new hires have already departed or never actually started, with at least two returning to OpenAI.

Why it matters: The story of the summer has been Meta’s poaching and the seemingly infinite amount of money being thrown towards reinventing its AI efforts — and while the vibes were strong externally surrounding the new talent infusion, it’s becoming clear that building a team and executing on Zuck’s vision will take more than just cash.

AI TRAINING

The Rundown: In this tutorial, you will learn how to use Genspark AI Designer to create posters, t-shirts, websites, and more from single prompts — it's like having design agents that search for inspiration before generating your custom layouts.

Step-by-step:

  1. Go to Genspark AI Designer and click into the prompt box

  2. Describe your design: "Create a t-shirt for a company boss that says 'The buck stops here'" or "Design a website for my tennis coaching business"

  3. Watch as Genspark's agents search the web for inspiration, analyze layouts, and then present 4 design options (from minimalist to bold vintage styles)

  4. Refine with follow-ups like "make it viral" or "make it modern minimalist" to improve results

  5. Download the mockup or take it to the GenSpark Developer Agent to convert designs into actual code

Pro tip: The free plan gives 200 credits daily that burn fast — use one-shot prompts wisely, then iterate with specific refinements like "highlight testimonials" or "add booking feature" for production-ready designs.

PRESENTED BY H COMPANY

The Rundown: Backed by a historic $220M seed round, H Company just open-sourced Holo1 — the open-source action model behind Surfer H that is now the top-ranked web-browsing agent on WebVoyager.

With Holo1, you can:

  • Automate multi-step browser workflows to reclaim hours of repetitive work

  • Experience SOTA accuracy that outperforms OpenAI’s Operator, Gemini Flash, & more

  • Integrate instantly with RAG workflows, RPA suites, and multi-agent hubs

  • Trim costs with full browsing flows at just $0.11 – $0.13 per run

Holo 1 is now freely available for deployment, fine-tuning, and scaling — learn more here.

AI RESEARCH

The Rundown: Researchers from Imperial College London published a study on using an AI-powered stethoscope that can detect major heart issues in just seconds, finding significant increases in potential life-saving early diagnoses over traditional tools.

The details:

  • The study tested the card-sized device across 200 doctors’ offices with over 12,000 patients, finding 2x rates of heart failure detection.

  • The AI analyzes heartbeat patterns and blood flow variations undetectable to human ears while simultaneously capturing ECG readings.

  • The cloud-based AI algorithms process waveform data from over 12,000 patient recordings to flag at-risk individuals within seconds.

  • Patients examined with the device also showed 3.5x higher detection of atrial fibrillation and nearly double the diagnosis rate for valve disease.

Why it matters: Like other AI medical tools, the key upgrade with the AI stethoscope, which is set to be rolled out across the UK, is proactive prevention. This implementation is also a great example of how a tool invented (and barely changed) since the 1800s can gain incredible powers with a bit of AI integrated into the design.

QUICK HITS

  • ⚙️ Grok Code Fast - xAI’s new speedy, SOTA coding model

  • 🗣️ Command A Translate - Cohere’s frontier enterprise translation model

  • 📞 gpt-realtime - OpenAI’s model for creating production-ready voice agents

  • 🎨 USO - ByteDance’s open-source image style editing model

Meta has reportedly discussed partnerships with Google and OpenAI to have third-party models power its Meta AI chatbot while the company trains its next-gen system.

ByteDance released USO, an open ‘style-subject optimized customization model’ that can preserve subjects and apply new artistic styles to create customized images.

UCLA researchers developed optical generative AI models, which create images using light beams instead of processors, capable of faster, energy-efficient outputs.

Higgsfield AI launched Higgsfield Speak 2.0, a new upgrade to its custom avatar tool with more realistic motion, advanced lip-sync, and enhanced video control.

A study found that exposing readers to AI-detection quizzes led to an increase in visits to trusted news sites, suggesting quality journalism may benefit from AI content.

Meta is facing backlash after the images and likenesses of celebrities like Taylor Swift and Scarlett Johansson were used for AI chatbots on its platform without permission.

COMMUNITY

Every newsletter, we showcase how a reader is using AI to work smarter, save time, or make life easier.

Today’s workflow comes from reader Jody W. in Nova Scotia, Canada:

"As an adult with ADHD, I use AI to keep things moving. It helps me get through the tasks that usually slow me down or stop me altogether, like organizing hours, writing up quotes, or keeping projects on track. Instead of getting stuck, I can keep my momentum and stay productive. I've always had a million great ideas and have never really been able to take action on them because of my scattered mind. Now with my AI assistance, I tackle complex problems with ease and have honestly never been more productive."
