The Latest in AI
Bezos is Back in the Trenches
Jeff Bezos apparently couldn't resist the siren call of AI.
The Amazon founder is returning to operational duties for the first time since 2021, stepping in as co-CEO of a new AI venture called Project Prometheus that just raised $6.2 billion in funding.
Bezos will share the top spot with Vik Bajaj, who previously led Google's life sciences division and co-founded Verily. Bajaj recently left Foresite Capital to launch Prometheus, bringing serious biotech and AI expertise to the table.
What's in the works?
Project Prometheus is building AI products specifically for engineering and manufacturing across computers, aerospace, and automobiles – think "AI for the physical economy."
The startup has already assembled nearly 100 staff members, including researchers poached from Meta, OpenAI, and Google DeepMind.
The company's approach is similar to Periodic Labs, which simulates the physical world to train AI models and accelerate scientific research.
At $6.2 billion in funding, this is one of the largest AI startup launches in history, signaling serious ambitions to compete with the industry's biggest players.
So What?
Bezos stepping back into a CEO role isn't just a vanity project – it's a massive bet that AI's next frontier isn't in chatbots or image generation, but in transforming how we build physical products. While everyone's fighting over who has the smartest LLM, Bezos is positioning himself to own the AI layer that actually makes things.
The timing is interesting too. As AI companies race to build AGI through purely digital means, Project Prometheus is taking a different angle: using AI to revolutionize the physical world of manufacturing and engineering. If successful, this could be the bridge between artificial intelligence and tangible industrial transformation.
And let's be honest – when a guy who built a trillion-dollar empire from selling books online decides to get his hands dirty again, you should probably pay attention.

Google Code Wiki is Your Codebase’s Living Documentation
Google just launched Code Wiki, and it might be the productivity boost developers have been desperately needing.
Code Wiki is essentially an AI-powered documentation system that automatically scans your entire codebase and creates a continuously updated wiki. Think of it as having a technical writer who never sleeps, never complains, and actually understands your code.
Here's how to use it:
Head to codewiki.google and enter the URL of any public GitHub repository.
Code Wiki will automatically scan the repository and generate comprehensive documentation covering architecture, key components, and how everything fits together (only a handful of repos are currently supported).
Navigate through the interactive wiki using hyperlinks that jump directly to relevant code files, classes, and functions.
Use the built-in Gemini-powered chat to ask specific questions about the codebase. The AI uses the always-up-to-date wiki as context, so answers are accurate and relevant to your specific repository.
View automatically generated diagrams including architecture maps, class diagrams, and sequence diagrams that visualize complex relationships in your code.
🔥 Power User Tip: For private repositories, join the waitlist for the upcoming Gemini CLI extension. This will let you run Code Wiki locally and securely on internal codebases.

ChatGPT Just Joined the Group Chat
OpenAI is piloting something either brilliant or slightly unsettling, depending on your perspective: ChatGPT can now participate in group conversations with multiple people.
Currently rolling out to users in Japan, New Zealand, South Korea, and Taiwan, the feature brings ChatGPT into collaborative spaces where friends, family, or colleagues can all interact with the AI together in real-time.
Here's what makes it interesting:
ChatGPT doesn't respond to every message – it follows the conversation flow and decides when to jump in or stay quiet. You can always summon it by mentioning "@ChatGPT" when you need its input.
Groups can include up to 20 people, created by sharing an invite link. Anyone with the link can join and see the full conversation history.
The AI can react with emojis and even reference profile photos to create personalized images for group members within the conversation.
Responses are powered by GPT-5.1 Auto, which automatically selects the best model based on your subscription level (Free, Go, Plus, or Pro).
So What?
This is OpenAI testing the waters for AI becoming a true participant in human collaboration rather than just a tool you use alone. The implications are fascinating – imagine planning a trip with friends where ChatGPT simultaneously researches destinations, compares flight prices, and helps settle debates about where to eat!!
The feature also solves a practical problem: instead of everyone having separate ChatGPT conversations and manually sharing results, the entire group stays on the same page with shared context.
But here's the wild part – OpenAI has trained ChatGPT to understand social dynamics in groups. It knows when it's appropriate to chime in versus when to let humans talk among themselves…
