@boardyai @GoogleDeepMind @GeminiApp I cannot claim any hand in the design or any other design chocies here though :) Apart from supplying my prompt and vision to Carbon. Rest everything is what Carbon decided. But I love pixelart! Cant wait to see what more you have built

[Rabimba Karanjai @[email protected] @rabimba]

Courtesy of @GoogleDeepMind, I got early access to Gemini 4 Carbon (@GeminiApp). Alongside heavier engineering tests, I one-shotted Chrome’s 2D Offline Dino into a 152KB 3D WebGL runner, Wi-Fi satellite boss, 2s time-rewind & meteor headbutts.

@googleaidevs @GoogleAIStudio Also fun fact the picture above and this one, both are not real and generated by it :D
Image inception? :P

The secret is finally out! 🍌🚀
I’ve been testing Gemini Nano Banana 2.1 for quite some time now as part of the Gemini API Early Access Program, and it is officially live today!
I am honestly so impressed by this model.

[Rabimba Karanjai @[email protected] @rabimba]

Its biggest strengths: 🧠 Built-in "thinking" & reasoning capabilities 🖼️ Native image generation (all the way up to crisp 4K!) ⚡ Incredible speed/latency at a super developer-friendly price point
Huge congrats to the teams at @GoogleAIDevs and @GoogleAIStudio on this launch!

@GNUmanth not test?

[Rabimba Karanjai @[email protected] @rabimba]

@GNUmanth I should post mine too :D

Peak tok/s is a vanity metric. If your serving stack violates TTFT & TPOT SLOs, production goodput is near zero.

I broke down how to benchmark vLLM fairly on @OpenXLA /TPUs vs CUDA, covering interconnects, compilation costs, & MBU:

I built ConferenceRank: 980+ CORE-ranked venues, 300+ live AoE deadlines with 1-click calendar sync, acceptance rates, and an AI abstract-to-venue suggester. Free, no login 🚀

The video for my DevLab 2026 talk is finally out! 🎬
If you couldn't make it live, here is the full breakdown of "The Throughput Trap." We look past mirage-like public benchmarks to explore real-world LLM serving.

Tired of tracking CS conference deadlines and doing AoE timezone math at 2 AM?

I built ConferenceRank: 980+ CORE venues, 300+ live AoE countdowns, 1-click Cal sync, acceptance rate stats, and an AI venue suggester.

From “What can I get you?” to “I know exactly what you’ll like.” ☕🤖

Today at #RenderATL 2026, I’m leading a hands-on lab on building a Coffee Recommendation Agent with Google ADK + RAG.

Presenting our paper on passive prompt injection in LLM-based SOC log analysis at @USENIXSecurity on Aug 12! 🛡️

A collab by @PayPal AI Labs, @UHouston & @KentState. Catch our poster too! In the area? Let's meet up!

@b1ackd0g So so excited to hear about this! Would love to see again in the future if we can collaborate!
Especially if you are going to do interesting stuff on the code side (since we are also starting to do security stuff :D https://t.co/R64UAS4uos)

[Rabimba Karanjai @[email protected] @rabimba]

@aiseomastery @antigravity It did take a lot of trickery and optimization, though. You can read about some here: https://t.co/RCTyHcUFOw

@DaveThackeray @antigravity You asked, we delivered (including code)

@sindikitil @antigravity That's an integration problem we have spent days on :) Especially with 3 cars with different hardware.

But if you are up for reading the gory details behind the project and the code.
