Read Online | Sign Up | Advertise | | | Good morning, AI enthusiasts. xAI just pulled off one of the boldest moves in tech with its SpaceX merger. But behind the scenes, the people who helped build the company keep walking out the door. | The departure of Tony Wu and Jimmy Ba now makes five co-founders gone in under a year — a pace of turnover that's raising questions about what's happening inside Musk's AI operation as it scales into orbit. | Reminder: Our next live workshop is today at 2 PM EST! Join for pt. 1 of our Agentic Workflows Bootcamp, where you'll learn automation and evaluation techniques that actually deliver results. RSVP here. | | In today's AI rundown: | xAI's cofounder exodus continues Ex-GitHub CEO's startup lands $60M Improve Claude Code with "Insights" feature Harvard finds AI tools expand workloads 4 new AI tools, community workflows, and more

| The Rundown: xAI co-founders, Tony Wu and Jimmy Ba, just announced their departures from Elon Musk's AI startup, making them the fourth and fifth founding members to walk away from the company, coming right after its SpaceX mega-merger. | The details: | Wu posted on X that it's "time for my next chapter", saying a "small team armed with AIs can move mountains and redefine what's possible". Wu led Grok's reasoning efforts and reported directly to Musk, joining xAI from Google in 2023, with no reason given for his departure. Ba announced his departure late Tuesday, saying that 2026 will be the "busiest and most consequential year for the future of our species." Musk had reportedly "grown frustrated" with delays to new Grok models in recent weeks, with its anticipated 4.20 update still awaiting release.
| Why it matters: xAI has a SpaceX merger in motion, accelerating model competition, deepfake blowback, and now a wave of senior exits is a lot of fires for a startup whose ambitions just jumped to space-based data centers. If there is anyone used to juggling chaotic situations, it's Elon — but this leadership exodus is starting to raise questions. |

| | TOGETHER WITH LAMBDA | | | The Rundown: AI changed meaningfully in 2025, not just in research, but in production. Lambda's 2025 AI wrapped breaks down the shifts that defined the year, from reasoning models and larger context windows to multimodal capabilities, open-source viability, and inference-first workloads. | Key shifts covered: | Reasoning, long-context, and multimodal models Open-source and MoE-driven efficiency gains Inference overtaking training in production

| The Rundown: Ex-GitHub CEO Thomas Dohmke raised a record $60M seed round for Entire, an open-source developer platform designed to track and manage AI-generated code that is increasingly being shipped without humans reading it themselves. | The details: | Dohmke left Microsoft-owned GitHub last August after four years, saying the dev tools he built weren't made for a world where agents write the code. Entire's first release is Checkpoints, which logs AI agent actions like prompts and decisions while coding, so devs can better audit the outputs. The tool works with both Claude Code and Gemini CLI, with OpenAI's Codex and GitHub support coming soon. The $60M seed round is the largest ever for a dev tools startup, putting the company's initial valuation at $300M at launch.
| Why it matters: Dohmke helped lead the platform where most of the world's code lives, and him now building the agentic tooling layer is a strong signal of where the industry is heading. As AI generates more code than humans can review, helping devs trust and manage the output could be just as important as the agents themselves. |

| | AI TRAINING | | | The Rundown: In this guide, you will learn how to use the Claude Code's "insights" feature to improve your coding habits. This hidden, built-in report gives you feedback directly from Claude Code, and will even build you custom skills and agent instructions. | Step-by-step: | Open a new terminal session. Run the command claude /insights. Claude should begin working on your insights report. When it's done, it will give you a link to a file named report.html. Copy it into an empty folder. Open your code editor (we use Cursor). Start the webpage with cmd + shift + p and find the "Open Live Server" tool. You'll see the report outlining what worked, what didn't, and how to improve. Use the "Existing CC Features to Try" section for new project instructions.
| Pro tip: You can also give the HTML to Claude/ChatGPT and have the assistant run it. |

| The Rundown: A new Harvard Business Review research found that AI tools at a U.S. tech company didn't lighten employee workloads over 8 months, but actually grew them, with workers taking on broader tasks, logging more hours, and multitasking more. | The details: | The study tracked ~200 employees who adopted AI on their own, observing work habits and conducting 40+ in-depth interviews over eight months. Workers utilizing AI expanded well beyond their roles, with the tech making unfamiliar work feel doable. The study also noted AI blurring lines between work and rest, with employees firing off prompts after hours or during breaks. Engineers also reported spending more time reviewing and coaching colleagues on AI-assisted code, with "vibe-coding" help requests piling up.
| Why it matters: AI was supposed to free workers up, not quietly pile more on their plates — but that's exactly what Harvard found happening. The tech's productivity gains are real, but so is the tradeoff of broader roles, blurred boundaries, and a new work pace that is changing more quickly than many employees are likely ready for. |

| | | | | 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 Devin P. in Talladega, AL: | "I'm a blind person, so I use screen readers to use computers and phones. Even though the Android apps for a lot of AI apps could be more accessible to me, the CLI coding packages, like Codex and Gemini CLI, are pretty nice. I first used Gemini to make Termux, a Linux Terminal app for Android, more accessible, resulting in Talking Termux. | I then had AI set up Emacs with a speech system called Emacspeak, dealing with Termux's differences to Linux, and the lack of a TCLX package. After all that, I wanted to have some fun, so I had Codex create ElMUD, a way to play some online text-based games, including sounds for some of them." | How do you use AI? Tell us here. |
