I love the probabilistic nature of this. Presentations could be anywhere from extremely impressive to hilariously embarrassing.

It would be so cool if it generated live in the presentation and adjusted live as you spoke, so you’d have to react to whatever popped on screen!

and with neuralink it would generate slides of the audience naked

Bigger chip = more surface area = higher chance for somewhere in the chip to have a manufacturing defect Yields on silicon are great, but not perfect

Does that mean smaller chips are made from smaller wafers?

Nope. They use the same size wafers and then just put more chips on a wafer.

really too bad that the codex models are so tightly coupled to the codex harness as to be useless for everything else edit: not useless in a absolute sense, but worse than the vanilla gpt models

GPT-5.2-codex or 5.3-codex Works pretty well for me in opencode

Nope. They use the same size wafers and then just put more chips on a wafer.

So, does a wafer with a huge chip has more defects per area than a wafer with 100s of small chips?

> What am I missing? Largest production capacity maybe? Also, market demand will be so high that every player's chips will be sold out.

> Largest production capacity maybe? Anyone can buy TSMC's output...

Which I'm sure is 100% reserved through at least 2030.

There’s an expected amount of defects per wafer. If a chip has a defect, then it is lost (simplification). A wafer with 100 chips may lose 10 to defects, giving a yield of 90%. The same wafer but with 1000 smaller chips would still have lost only 10 of them, giving 99% yield.

Wow, I wish we could post pictures to HN. That chip is HUGE!!!!

The WSE-3 is the largest AI chip ever built, measuring 46,255 mm² and containing 4 trillion transistors. It delivers 125 petaflops of AI compute through 900,000 AI-optimized cores — 19× more transistors and 28× more compute than the NVIDIA B200.
