@FeiziSoheil @PKattakinda @406Ventures Huge congratulations Soheil!!
All the best 👏🎉

Looks like we are back to using Paint for making logos

@PKattakinda Gemini prompt 🫣

Someone is leaking their own system prompt 🫣

@Steve_Yegge @demishassabis I’m not sure how burning 15M tokens per day directly translates to AI adoption at work.

More the tokens != better the work.

Is Claude the rubber duck or are we it’s rubber duck? 🦆 🥺

@qrsupport @qatarairways When the customer care admits the rules are not provided to the customer. But still want to impose it on them to make money for free.

Gemini 3 and GPT 5 improvements show pre/post-training and test time scaling has not hit a wall!

[Vinu Sankar Sadasivan @imVinusankars]

I agree with this. We haven’t hit a wall on data (let alone text). And for world models, the total entropy of the universe is non-decreasing. Data is all around us. We just don’t know how to efficiently extract them :)

[Vinu Sankar Sadasivan @imVinusankars]

Gemini 4 wen?

[Vinu Sankar Sadasivan @imVinusankars]

@StefanFSchubert @jburnmurdoch This is a very bad metric to draw any reasonable conclusion. We should at least be looking at sample-wise variance and be accounting in for the changes in number of active users.

[Vinu Sankar Sadasivan @imVinusankars]

One major thing we might be missing when people say AI would be good to replace even super humans:

using AI assistance might unlock “ultra super” human capabilities in humans as we evolve? 🧐

[Vinu Sankar Sadasivan @imVinusankars]

I agree with this. We haven’t hit a wall on data (let alone text). And for world models, the total entropy of the universe is non-decreasing. Data is all around us. We just don’t know how to efficiently extract them :)

IMO — Ilya is wrong

- Frontier LLMs are are trained on ~200 TBs of text
- There's ~200 Zettabytes of data out there
- That's about 1 billion times more data
- It doubles every 2 years

The problem is the data is private. Can't scrape it.

The problem is not data scarcity, it's data access.

The solution is attribution-based control (article below)

Curious to see if this can help Pixel Watches capture more customers…

Google DeepMind just dropped a Nature paper: “A personal health large language model for sleep and fitness coaching.”

> Gemini is better that doctors and trainers at sleep and fitness
> paper shows huge benefit of AI personalization for health and long-form coaching

Honestly personal health AI with a full comprehensive understanding of every one of your vitals and metrics will be one of its greatest AI usecases for a long time.

Has Perplexity gone a bit slower and less smart or is it just me?

[Vinu Sankar Sadasivan @imVinusankars]

@subhash_wnc @AIatMeta @Meta Thanks Subhash :)

[Vinu Sankar Sadasivan @imVinusankars]

I am extremely delighted to announce that I will be joining @AIatMeta as an AI Research Scientist starting next week in Menlo Park! I will be working on continuing my AI safety research efforts.

Exciting… I feel blessed and grateful to my advisor, family, and friends 😇
