Welcome, humans.

If you're building stuff with AI in 2026 (and honestly, even if you have no software experience, you should be playing around with this stuff!), you need to know where the industry's headed, and how to avoid the common mistakes that trip people up.

Speaking of which, @maddiedreese just dropped an incredibly useful thread on beginner vibe coding mistakes that's genuinely worth reading. Forgetting favicons, skipping mobile testing, not reading API docs, etc. Basically, all the stuff that'll save you hours if you catch it early. Definitely worth a read!

ChatGPT Health, AI doctors in Utah, and AI disease detection…

NEWS BRIEF: Why this might be the biggest week in AI healthcare yet

Grant here. Over the weekend, my sink clogged. I (perhaps unwisely) combined an enzyme cleaner with some soap and hot water, and a scary red chemical goo (with a scary chemical smell) started emanating from the drain.

So I did what any rational person would do: I opened ChatGPT, started a live video session, and asked it if I was about to die.

Bold? Yes. Stupid? Also yes. But it walked me through what was causing the smell, confirmed I wasn't about to pass out from toxic fumes (and gave me some precautions to take), and helped me survive until the plumber arrived Tuesday. Thanks, Chat!

Which is why OpenAI's announcement of ChatGPT Health this week hit different.

Here's what's actually new: ChatGPT Health is a new, dedicated space with its own privacy architecture for sharing your medical record:

Health conversations stored separately, not used for model training, protected by purpose-built encryption.
You can now connect actual medical records and wellness apps like Apple Health, so ChatGPT can reference your real health data when answering questions.
OpenAI worked with 260 physicians across 60 countries who provided feedback 600,000+ times to shape how the model responds.

The scale of impact here is staggering: 230+ million people already ask ChatGPT health questions weekly.

But it's also personal: In her own announcement post, OpenAI CPO Fidji Simo shared that ChatGPT once flagged a dangerous antibiotic interaction that her hospital's resident had missed because she only had 5 minutes to review the chart. That's the gap in care this product is designed to fill. Sign up for ChatGPT Health waitlist here.

Meanwhile, Utah became the first state to let AI prescribe drugs.

The state partnered with Doctronic to let AI autonomously renew prescriptions for chronic conditions via 190 eligible medications (excluding opioids and injectables).
The AI matched physician recommendations 99.2% of the time in testing.
Now, a dozen other states are expected to follow in 2026.

And from Stanford: AI can now predict disease from a single night's sleep. A new Nature Medicine study introduced SleepFM, trained on 585,000+ hours of sleep data. From one overnight recording, it predicts dementia (0.85 accuracy), heart attack (0.81), heart failure (0.80), and all-cause mortality (0.84). That's years before symptoms appear.

And the WSJ reported that 27% of US health systems are now paying for commercial AI licenses; 3x the broader economy. Epic's AI appeal tool now runs in 1,000 hospitals, and Northwestern radiologists cut X-ray report time from 75 to 45 seconds (time is money, friends).

The reality check: AI still misses nearly one-third of breast cancers in dense tissue. That number was improved over time with additional guradrails to catch what the AI missed, but it proves AI still works best alongside humans; each catches what the other misses. They say you need to get a second opinion, after all.

Our take: I've been thinking about the AI backlash lately. It's really an anti-big corporation backlash. Who hates the concept of a doctor in their pocket? But people who hate AI hate that it answers dumb, or that it might replace and surveil them.

Well, healthcare AI isn't replacing doctors; it's filling a gap in care that just doesn't exist. You can't have a real doctor in your pocket (unless they're tiny!). Meanwhile, wait times to see one stretch months. Rural areas face severe shortages. And even when you see a doctor, they typically only have 5 minutes with your chart.

Make no mistake, the AI available today can save your life in a given situation (with the right context). But the AI that's coming next can help you live a better one: predicting disease before it strikes, making sure your pills never lapse, and monitoring patterns you and your doctor might never notice otherwise.

This is the future we want and deserve: personalized medicine, always available, actually accurate. We can have it, if we do it right.

That last part is the key question that needs to be solved.

Prompt Tip of the Day

If you haven't tried Claude Code yet (because, y'know, you're not a coder?), this 47-min video from Peter Yang (we love Peter's videos!) might convince you to start. He interviews product coach Teresa Torres, who uses Claude Code to run her entire life.

What is Claude Code? Unlike chatting in a browser, Claude Code can read your files, execute commands, search the web, and remember context across projects. Think of it as hiring a $100/month assistant who lives inside your computer.

What Teresa does with it is wild:

Types "today" and Claude generates her complete to-do list—checking her Trello, scanning deadlines, even pulling relevant academic research.
Writes with Claude as a thought partner (like 9,000-word blog posts).
Asks Claude to do odd jobs like "what keywords should I target?" and does SEO research by analyzing what's ranking.
Has Claude interview her about her business, then auto-generate context files so she never repeats herself.

The key insight: Teresa treats Claude Code like pair programming for everything; writing, research, task management, strategy. The video walks through her exact setup, including how she organizes context files so Claude knows about her business without crowding every conversation.

Our favorite tip: Whenever you find yourself explaining context to Claude, stop and ask: "Will I ever have to explain this again?" If yes, have Claude save it to a file. You'll never repeat yourself twice.

Also, after every session, she says to ask Claude "What did you learn about me that we should add to a context file?" Let Claude maintain its own memory. Def watch this one.

Around the Horn

xAI raised $20B, blowing past its $15B target, with backing from NVIDIA, Cisco, and Qatar's sovereign wealth fund; the company said it ended 2025 with over 1M H100-equivalent GPUs, ~600M monthly users across X and Grok, and Grok 5 already in training.
Caterpillar partnered with NVIDIA to bring AI to its construction equipment, piloting an AI assistant called "Cat AI" (me-ow) in its mini excavators and demoing digital twin technology at CES.
Anthropic is reportedly raising $10B at a $350B valuation, nearly doubling its value from a $183 billion round just three months ago.
Google and Character.AI negotiated the tech industry's first major settlements in cases where teenagers died by suicide or harmed themselves after interacting with Character.AI's chatbots.
Ford announced an AI assistant coming to its app and vehicles, along with a next-generation BlueCruise system that's 30% cheaper and will enable eyes-off driving by 2028.
