Excited to share my latest blog series on generative models, specifically diffusion models! I've included the basic math and code to help you understand the concepts. Check it out here: https://t.co/geYR9oVLr3 #generativemodels #diffusionmodels #machinelearning #AI

This is nothing. At Fermi we are removing all distinctions between who can code and who cannot. We are building a team that operates like how companies of AI age would. Coding is just a mechanism, if you can dream big reach out to us. @fermi_ai

you don't need a time machine, you can still try out your chops at JEE questions, like I did this morning, with
@fermi_ai -- students use it to solve the questions
@GeminiApp generates and see where they can do better...

[Fermi @fermi_ai]

Watching them lean in, pick up the stylus, engage in productive struggle, try again, and smile when things clicked was a reminder of what we’re really building. 
Not shortcuts. Not answers.
Just the love of learning, and the confidence to tackle harder problems.

Most AI tools are just answer machines. At Fermi, we encourage the productive struggle that serves as a bridge to mastery. Wanna know how? Hear directly from one of our learners.
Stop Prompting, Start Learning!

The problem is not the questions.
The problem is the system that produces them.

Don’t strip details away to make a complex topic “simple.”
The goal is to make it easier to understand without losing the depth.

I switched to AI Engineering 2 years ago!

It was the best career move I ever made.

If you want to start today, here's a roadmap:

[Aravind Srinivas @AravSrinivas]

No amount of money can buy you the feeling of pouring all your energy into something and sleep drained of all mental energy and wake up with the excitement to go do it again. If you’re going thru that dynamic already, don’t be a sell out. Persist and shape the world to your liking.

Skip India Movement

AI founders finally skipping selling to Indian customers after doing PoCs after PoCs and then being requested for even more "free" PoCs.

There is a limit to this and founders are saying screw it and skipping selling to Indian customers. Enough is enough. Even unicorns are using these startup founders (who are 10x better than their internal teams) for freebies.

I guess somethings never change!

PS: This is based on primary data :)

When you ask 500 AI personas who they'll vote for, 90% of them choose Kamala over Trump... Here's how I used @DSPyOSS to completely remove bias:

[Nikki Haley @NikkiHaley]

Terrorists launched an attack that killed dozens of Indian citizens. India had every right to retaliate and defend itself.

Pakistan does not get to play the victim. No country gets a pass for supporting terrorist activity.

OPENAI ROADMAP UPDATE FOR GPT-4.5 and GPT-5:

We want to do a better job of sharing our intended roadmap, and a much better job simplifying our product offerings.

We want AI to “just work” for you; we realize how complicated our model and product offerings have gotten.

We hate the model picker as much as you do and want to return to magic unified intelligence.

We will next ship GPT-4.5, the model we called Orion internally, as our last non-chain-of-thought model.

After that, a top goal for us is to unify o-series models and GPT-series models by creating systems that can use all our tools, know when to think for a long time or not, and generally be useful for a very wide range of tasks.

In both ChatGPT and our API, we will release GPT-5 as a system that integrates a lot of our technology, including o3. We will no longer ship o3 as a standalone model.

The free tier of ChatGPT will get unlimited chat access to GPT-5 at the standard intelligence setting (!!), subject to abuse thresholds.

Plus subscribers will be able to run GPT-5 at a higher level of intelligence, and Pro subscribers will be able to run GPT-5 at an even higher level of intelligence. These models will incorporate voice, canvas, search, deep research, and more.

Unspoken desires remain unfulfilled; only the voiced demand invites its realization.
