VehicleLab v1.0 released!

One of the cool features is video export: sharing a test simulation video showing 4DOF suspension model showing how car would behave when it meets predefined sinusidal bumps! #vehicledynamics #simulation #DigitalTwin

[Varad Karkhanis @varadkarkhanis]

@krupakotecha_ Sounds like this will be the reality soon!

[Varad Karkhanis @varadkarkhanis]

@aapakari I think this is that time

If you love exploring automotive related simulations, let me know your f/b on vehiclelab.

@Vinkarkhanis This is really cool!

[Varad Karkhanis @varadkarkhanis]

Big updates!

[OpenAI @OpenAI]

We’re releasing a broad range of new mathematical results produced by an internal frontier model.

We’ve been consulting with the independent Advisory Group on Mathematics and Artificial Intelligence at the Institute for Advanced Study, and we have drawn on their advice and public recommendations to inform how we release these results.

New image model from Google is here!

[Google @Google]

Meet Nano Banana 2.1, our latest image generation and editing model 🍌

This upgraded version outperforms our previous models across the board, with notable leaps in visual design, mask-based editing, and subject consistency to help you create more natural-looking images.

[Varad Karkhanis @varadkarkhanis]

This is a great game my brother built. I invite all of you to come and try it out. Any feedback is welcome!

[Vinayak Karkhanis @Vinkarkhanis]

Today’s Wanderlane dev preview: clearer turns, a gentle parking countdown, warm chai-stall lighting and a postcard to keep. Sound on for the arrival chime. ☕🚗

@Vinkarkhanis Tea breaks are essential!

[Varad Karkhanis @varadkarkhanis]

@ayesha_fatiima Can certainly be built, but software stack itself will evolve. Compilers would not be needed anymore beyond AGI world, ai/si will directly write machine level code!

[Varad Karkhanis @varadkarkhanis]

AI models are getting seriously good at engineering visualization.
I used GPT-6.1 Sol to create this short educational video explaining the quarter-car model behind VehicleLab.
Sometimes, before running a simulation, it helps to first see and understand the model.
The video was generated from code using Three.js → deterministic frames → MP4, with narration and sound design.
No screen recording. Just a small experiment.
Pretty amazing to see what today’s AI models can build. 🚗⚙️

GPT6.1 sol: early review.
Using this model on 'high' setting for my vehicle lab work from past couple of days. Some of the prs that it is bringing for my review involves complex engineering and math work. I must say so far 6.1sol is mostly matching astra level intelligence while super token efficient. Still more elaborate tests are pending, but thought of sharing early review. Feel free to share your experience as well.

[Varad Karkhanis @varadkarkhanis]

This is the power of today's ai models- capable of coding everything in 3.js, probably we figured out a new way to generate educational videos?

[Vinayak Karkhanis @Vinkarkhanis]

From Mercury’s craters to Saturn’s rings—and beyond Neptune. ☀️🪐
I built this 4-minute solar system journey with Three.js, featuring detailed planets, voice-over explanations, and imagined planet sounds.
Which planet would you visit?

@Vinkarkhanis Very informative!

[Varad Karkhanis @varadkarkhanis]

@Vinkarkhanis Great work!

[Varad Karkhanis @varadkarkhanis]

@Vinkarkhanis Sundar.

[Varad Karkhanis @varadkarkhanis]

@Vinkarkhanis It is fun game!

[Varad Karkhanis @varadkarkhanis]

@Vinkarkhanis Lolz

[Varad Karkhanis @varadkarkhanis]

And this comes...

[Google DeepMind @GoogleDeepMind]

Introducing Gemini 4 Argon – our new frontier model.

It’s built for complex workflows across coding, enterprise knowledge work, and cybersecurity defense – rolling out today to a set of trusted testers through our Fairwind Program.

[Varad Karkhanis @varadkarkhanis]

@Vinkarkhanis Makes sense

[Varad Karkhanis @varadkarkhanis]

@Vinkarkhanis since you are using both codex and GitHub copilot to use astra, do you see any difference in performance if harness is changed?
