I asked this!!!!!!!!!!!! 🤯

[Ishan Sharma @Ishansharma7390]

I've been trying out the Gemini 4 Argon model and I think it is exceptionally better at writing scripts, posts, and articles compared to GPT-6 Astra or Opus 5.5. It feels a lot more human.

Has anyone else experienced this?

@topphamilia We are building a third place where people can hangout, meet real people and make new connections.

AI benchmarks are like school report cards.

One AI might be great at coding. Another might be better at solving problems or using your computer.

The best AI is the one that gets your job done.

Anyway, back to building.

Lots of discussion out there about our next model(!), so I wanted to give an early look as soon as possible. Introducing Gemini 4 Argon!

It shows frontier performance in complex workflows, cyber defense and software engineering. Teams are using it extensively at Google, from coding to quantum computing, great feedback.

Here’s a look at the benchmarks:

Listen Brooo!!!!

AI can give you 10x more output. It cannot give you taste.

The most important skill over the next 12 to 18 months is not prompting. It is judgment.

Back in August, when the first two tickets for our event "Match or Memories" sold, I could not stop smiling at my phone.

Nothing beats the feeling when an idea in your head turns into real people actually paying to show up.

The HYROX experiment https://t.co/49RnsFBVzP inflates this month's revenue, but it's the best month ever for my marketplace https://t.co/MZc8tGa5LQ ($53K) and my SaaS https://t.co/3EDxln5U2Q ($31K).

I do everything solo, and I'm not going to lie, I'm fucking proud of myself.

Since I was a kid, I've been told to focus on one thing. I find that boring. I want to play and try a bunch of things.

I never felt confident because nothing really worked out for 7 years. I ended up being average at everything: coding, marketing, design...

But building 37 startups (https://t.co/4zCWHGJWRq) taught me something far more important: resilience, discipline, and optimism.

Over the past decade, those skills have compounded. I now run a tiny portfolio of startups making $1M+/year, sleep 8 hours a night, work out 2 hours a day, and spend plenty of time with my wife.

Anything is possible if you're hungry.

Believe in yourself.
