Hi! this is Rohan Anil, I develop training algorithms among other things - my work trains various frontier models.
At CoreAuto, I was fascinated by the problem of training on compute islands, eventually in space training.
I hope you all enjoy this write up!🪐🛰️

RIP Popular Mechanics
The lead story in the new issue of Popular Mechanics is “How to Fight a Data Center.”
How sad and bizarre. Another once-great technology magazine turned against technology by leftists.

Today we’re releasing GDPx, a benchmark for measuring agentic capabilities across the most valuable domains.
GDPx is a true frontier-level benchmark: even the best model scores just 12% (1/7)🧵
Just published a Grok @Bot to remove my number from spam call lists and one to remove my personal info from public sites

Gemini 4 Argon has proven to be outright unusable for real code work in my codebases. It aggressively hallucinates about how systems work.

We discovered a sophisticated recording device that was hidden inside one of our offices. We used our models to understand the device and where it had come from, identifying that a specific employee had planted it a few days earlier. We referred the matter to the FBI, and we’re grateful to the agents and prosecutors who moved quickly to make an arrest. The FBI’s investigation is ongoing and we will continue to support their work.
At this time, we have no indications of this individual inappropriately accessing or exfiltrating model weights, source code, or customer data. The employee was terminated.
We take protecting our technology, data, and people seriously, and as a matter of national importance. Our security program is designed to protect against a wide range of threat actors, from insider risks to cybercriminals to nation states, and this case is an example of how AI can help address these sophisticated security threats.

Technical moats are mostly over at this point. If you’re building something that is meant to be durable, the only moats now are:
• Proprietary data
• Network effects
• A physical component

So I tested GPT-6.1 Sol on real work: 2 repos, 105 planted bugs. Find and fix what you can.
Unlike GPT-6 Sol, which was just a nerfed GPT-5.6 Terra, this one is real. The results:
- GPT-6 Astra (max): 45 for $33
- GPT-6.1 Sol (max): 44 for $6.56
- GPT-5.6 Sol (max): 43.5 for $95.35
- Opus 5.5 (max): 41.7 for $58.53
- GPT-6 Sol (max): 29.3 for $9.33
With a model like this, the 50% cut to the $200 plan doesn't matter.
n=1. More runs and results at more effort levels dropping in this thread over the next few hours 🧵

Bullish on open source, open weights, the open web
And the open desktop
Personal Operating Systems feel like the natural next step after Personal Software
I've been building a Debian-based OS for myself that can run across physical machines and cloud environments like Vercel Sandbox
I can use and control it with natural language, and I'm designing the UI around a blend of ephemeral and persistent views rather than treating the desktop as a fixed set of apps and windows
There's something really special about having control over the UI/UX of the Whole Computer
