SITUATION DETECTED: Microsoft is limiting internal employee use of Fable 5 over Anthropic's new data retention requirements, per The Verge.

Fable 5 requires data retention to operate its safety classifiers, unlike other Claude models which run under Zero Data Retention rules.

So far this year buying NVDA GPUs is better investing than buying NVDA.

@dwarkesh_sp continues to ship!

These conversations are much appreciated. Takes me back to my CSCI/CompE days

New blackboard lecture w @reinerpope

How do chips actually work – starting with basic logic gates, and working up to why GPUs, TPUs, FPGAs, and the human brain each look the way they do.

0:00:00 – Building a multiply-accumulate from logic gates
0:16:20 – Muxes and the cost of data movement
0:25:59 – How systolic arrays work
0:39:00 – Clock cycles and pipeline registers
0:51:40 – FPGAs vs ASICs
1:03:14 – Cache vs scratchpad
1:07:16 – Why CPU cores are much bigger than GPU cores
1:11:49 – Brains vs chips
1:15:22 – A GPU is just a bunch of tiny TPUs

Look up Dwarkesh Podcast on YouTube/Spotify/etc to watch. Enjoy!

Remembering Martin Gardner, who passed away on this day in 2010 at age 95—a master of puzzles and recreational math.

Here’s one in his spirit:
“Can you pick six digits from the illustration that add up to 21.”

@0xSero Time to build that RF blaster

We’ve automated every single thing we can @every with AI agents.

And yet there’s way more human work to do than ever. We’ve gone from 4 -> 30 human employees since GPT-3.

I wrote a report on the structural reasons: how AI makes expert competence cheap, why that drives up demand for experts, and why the dynamic only intensifies as we approach AGI.

@juliarturc But the diffusion models generating the naked IG ladies also use attention->softmax

@loktar00 @ZenMagnets @microcenter Appreciate the monitoring because I grabbed a 3rd 6000 when you noted the price drop a couple weeks ago lol

Just one more to go... then another... and another...

First hummingbird of the season comes straight to the door as we are inside filling the feeder. Simply amazing!

How do they know?

[Marc Ohmann @marcohmann]

@ChujieZheng Great work! Will we see any larger model weights released?

[Marc Ohmann @marcohmann]

@ZenMagnets @OfficialLoganK @mercor_ai When running locally, I care more about intelligence/size

[Marc Ohmann @marcohmann]

@MTSlive Coming to their senses?

M2.7 evals cooking on the latest LoRA adapter. Takes the morning chill out of the office

[Marc Ohmann @marcohmann]

Do yourself a favor and start compiling SFT, DPO, and RLVR data and evals now.

If you have production workflows, preferences, and defined results, the data is evergreen and will only make future model drops fit that much better.
