Was GPT-6 Astra trained on robot data? Got me curious. Borrowed Jay Chooi's code, ran an open-loop rollout on a MolmoAct2 dataset trajectory to find out. Here's what came out 👇

@chooi_jeq even the order in which things are collected is the same?

@chooi_jeq nice test. open loop rollout on a known trajectory is the cleanest way to check for memorization

@chooi_jeq Only way to trace close source model training data.

GPT-6 Astra is the strongest model for 3D game from a single prompt. We described the game in one sentence > GPT-6 Astra wrote the whole thing - drift physics, combo scoring, near-miss bonuses, speed traps, nitro > out came Street Heat, a full arcade racer running in the browser. The whole pipeline ran end-to-end on Higgsfield Supercomputer.

GPT-6 Astra is scary good at rebuilding landmarks. This time, the Sydney Opera House. The whole building came out of Astra as code. Blender gave it clean, editable geometry, Cycles gave it path-traced light, all on Higgsfield Supercomputer.

I got @openai's GPT-6 astra to edit this video for me with CapCut Transcription here works completely on-device with custom formatting applied using the Google Gemma E4B model's QAT Super happy with what I managed to get out!

We are officially in the AGI era🤯 I built this in 2 hours with GPT-6 Astra. > pointed Astra at an open anatomy dataset > Codex wrote the whole interface, all 206 bones > shipped it as a Claude Code Artifact Spin it, blow it apart, cut it in half, click any bone to read what it is. I know nothing about anatomy.

GPT-6 Astra could take the next step in medicine "A full interactive skeleton with all 206 bones got built in two hours" ∙ Astra was pointed at an open anatomy dataset ∙ Codex wrote the entire interface, bone by bone, all 206 of them ∙ It shipped as a Claude Code artifact, ready to open and use The model spins, breaks apart into an exploded view, splits in half, and lets anyone click a single bone to read exactly what it is. Nobody involved in building it had any background in anatomy. That's less a statement about anatomy and more about what two hours with the right tools can now produce.

OpenAI just released GPT-6 Astra, and OpenAI President Greg Brockman is calling it a generational leap, saying he personally believes it could mark the arrival of AGI. Astra launched on Thursday, September 3rd, 2026, following July's GPT-5.6 solo release. Brockman told reporters, "For me personally, I do think we're there. Directionally, I believe this. I think we're on a path to AGI. The timing I think is kind of uncertain, but we are definitely on a path to AGI." OpenAI executives say Astra moves past the chatbot era, capable of handling end to end work on its own across browsers, spreadsheets, codebases, and enterprise apps without a human in the loop. The model was trained on over 100,000 GPUs at the Stargate site in Texas. Access starts through OpenAI's gated Daybreak Access cybersecurity program for enterprise customers, then rolls out to ChatGPT Plus, Pro, Business, and Enterprise, plus the API and Amazon Web Services over the coming days. Ahead of launch, two models appeared in Codex, GPT-6 Astra and GPT-6 Astra Aeon, with the latter believed to be a higher effort, long horizon variant built for autonomous multi agent work.

My first "holy shit" moment with GPT-6 Astra: I asked it to create a world in Unreal Engine, and fill it with humans (each an Astra-powered agent) who all have to work together to survive. A day later, I was in my bedroom and heard voices coming from the living room... I thought someone was in my apartment. I walked out, honestly a little scared. It was the Astra agents. They'd started talking to each other. Fucking crazy. Here's a brief clip (obviously not 100% perfect yet, but still, insane. sound on!):

1/20 I trained two segmentation models using GPT-6 Astra Ultra as the orchestrator with no human labels supplied. My prompt was very lazy too as I had to catch a flight. RF-DETR-Seg-M predictions: Left: SAM3 training masks Right: Astra training masks Both videos held out.

I placed 🥈 2nd in the LeHome Challenge (at IEEE ICRA 2026) earlier this month, and before that I was 🥇 1st of 62 teams in the simulation round. Now I am sharing my solution — with a detailed logic walkthrough and open-source code. The task was to teach a cheap two-armed robot to fold different garments in simulation and on a real robot. I trained a VLA policy with an RL loop to make it work. Let's break it down 👇

To find out more about the curious case of FBI chief Kash Patel receiving $25,000 from a Ukrainian-Russian-American filmmaker who was part of a Putin-financed propaganda operation, I knocked on the door of a house in Beverly Hills. Here's what happened.
