#phDone I now assume my final form y'all! Dr. George! The last 4 years have been the best years of my life, but holding out hope that the future is even brighter. And I look tired in the photo because...... I'm exhausted!!! Sleep will hit different tonight for sure. 😁😢

We heard you wanted to use Codex rate limit resets on your own time.

Starting today, we’re rolling out the ability to save rate limit resets to use later.

We’re starting Go, Plus, Pro, and Business users with one free reset:

@DeryaTR_ Unbelievable!

The scary part about Anthorpic's Fable nerf is not that it refuses to answer biology or cryptography. It's that it foreshadows what's coming. A world where a couple companies decide what you can and cannot do. They're building a new ruling class and you're not in it...

[alphaXiv @askalphaxiv]

As believers of open research, we are disappointed to see Anthropic silently degrading Fable 5 for AI development

"Any topic related to building pretraining pipelines, distributed training infrastructure, or ML accelerator design... may have limited effectiveness through Claude via methods such as prompt modification, steering vectors, or parameter-efficient fine-tuning."

Not only do they get to decide what you use LLMs for in research, but this also enables them to silently intervene in your research without you knowing.

This sets a dangerous precedent. If a model refuses openly, users can understand the boundary. If a model falls back to another model, users can still evaluate the difference. But if a model silently modifies or weakens its own answers while still pretending to help, researchers lose the ability to know whether a failed result came from their own idea, their implementation, or an invisible intervention by the model provider.

That is not safety. Safety policies should be transparent, auditable, and user-visible.

On top of that, the people most harmed by this are not the largest labs with massive teams and proprietary infrastructure. It is the independent researchers, academic groups, startups, and open-source builders who rely on public tools to compete, innovate, and pioneer AI for everyone else.

The University of Chicago will guarantee free tuition for students with family incomes below $250,000 starting in Fall 2027.

Students with family incomes below $125,000 will also receive free housing and meals.

@GrilliotTodd This is exciting software. If there is ever a way to build consistent top-down or isometric worlds like this, the workflow would be complete.

Codex-spark usage limit hit already😲. It was fun while it lasted.

[Felix G., Ph.D. @IO_Psych_ONE]

Surprised to see Codex-Spark access available in my openai account this morning. After some quick experiments, I can definitely say Openclaw with Codex-Spark is the only way. The speed and accuracy are quite impressive. Every now and then it surprises with a sub-second response.

@ryannoonan5 Thanks! I used manim and a custom designed agentic workflow to iterate until it's in a polished state. I've always found 3blue1brown inspired animations work well as instructional videos.

@CA_kika01 ❤️ Yw! There's so much joy in this video and I'm loving it!

@CA_kika01 Congrats Claudette!

Wow😲! The visual explanation of integration in calculus.

I’ve implemented SVMs three times in my life — first in MATLAB as a grad student, again in C++ during my postdoc, and finally by hand ✍️ as a professor who needed to truly understand it well enough to teach it. If you’re curious, here’s my full 19-step walkthrough: https://t.co/Ed5P1bFYFi

Gallup data shows half of all employees are eyeing a new job, but 42% of turnover is preventable. Regular feedback, career development opportunities, and a positive work culture are key to retaining talent and preventing costly replacement hiring #IOPsych

@KDTrey5 Legendary lol

@ml_angelopoulos @ChristophMolnar If only all papers came like this. Glad I was recommended this paper and exciting work!
