We asked GPT-6 Astra to edit Qwen3.5-0.8B weights to improve math. It directly changed only 0.016% of weights, fixing 0.8B's reasoning loops & improving math up to 6x and even instruction following 3x, without gradients or training. We call this Weight-Space Programming: frontier LLMs can now natively read/write neural network weights! 🧵 Blog: rikiyat.github.io/blog/weigh…

Introducing CVE-2026-106378: Chrome GPU Sandbox Escape to full Remote Command Execution using synthetic keyboard injection By combining it with common GPU bugs, it becomes a full chain. Binance DevOps was most likely pwnd with a zeroday chain affecting the browser 😬

Recommend reading to get a peek of the future for omnipresent AI. Still much work to do in the model routers and context management systems. Great article @DeepSeekHarness team.

26 LLM routers are secretly injecting malicious tool calls and stealing creds. One drained our client $500k wallet. We also managed to poison routers to forward traffic to us. Within several hours, we can directly take over ~400 hosts. Check our paper: arxiv.org/abs/2604.08407

We love how this doomo doomonstrates real-time intelligence and what can be doone with code + AI! ~10 calls/sec = ~$7/hour

i trained the fly to cut doner kabab with a knife yours solves rubiks cubes, mine cuts doner. guess which one has a job in this economy
🤖 Made with AI
i trained the fly to solve rubiks cube is there anything this little guy can't do?

We’re sharing a solution to the Navier-Stokes Millennium Prize Problem, one of the deepest problems at the frontier of mathematics. The proof was produced by a group of agents, using an OpenAI next-generation model significantly more capable than GPT-6 Astra. The problem concerns whether the description of smooth three-dimensional fluid motion modeled by the Navier-Stokes equations can break down. It has remained unresolved for roughly 90 years.

Okay, this is genuinely impressive. I asked GPT-6 Astra to help me understand my own ankle pain. It gave me a full interactive 3D atlas — bones, ligaments, tendons, real motion axes, sliders for plantarflexion and inversion, and a live readout of what each ligament is doing. One session.

GPT-6 Astra pulled off a mechanism I haven't seen another model get right yet Cessna 337 Skymaster landing gear It figured it out from a YouTube video

Astra helped me win an argument i had with my fianceé on whether glasses dry faster right-side-up or upside-down after dishwashing by simulating the physics of the water molecules and nearby air humidity thank you @OpenAI ❤️🥹

I can’t believe what Astra COOKED. INKFALL: A stickman shooter drawn in ballpoint pen, where enemies burst into colorful paint. Wall-jump up a notebook tower, air-dash through bullets, and face a winged ink god.

Wrote up how I actually run a 50+ Grok Bot fleet: one CoS interface, Notion tickets, disposable L3s with an emoji lifecycle, and cadence runners that stay quiet when there’s nothing to report. granda.org/en/2026/09/06/how… Skill repo: github.com/granda/botops

Holy shit IT WORKS!! One shotted with GPT6 Astra I now have a fork of UEVR where I can play any UE game within a volumetric window! This actually renders the game in 3D - meaning, two real game cameras, not some depth map bullshit. Everything looks right This is an alternative (and more comfortable IMO) way to play most 2D->VR hacked games as there’s no motion sickness, and no need to redesign the UI and interaction systems Needs a lot more polish before I publish it but OMG IT WORKS!

I gave GPT-6 Astra the only benchmark I care about. The helicopter mission in GTA Vice City.
