Standards have plummeted so badly that these two women are now considered celebrity crushes

Every AI chip on Earth starts as a crystal pulled from a pool of molten silicon at 1 millimeter per minute. TSMC, Samsung, and Intel cannot make them without it. In the Czochralski process, a seed crystal the size of a pencil dips into a crucible at 1,414°C. As it is slowly pulled upward, silicon atoms lock into a single crystal lattice. The boule grows to 300 millimeters in diameter, 2 meters in length, and 265 kilograms. Purity: 99.999999999%. Nothing humans have ever made at industrial scale comes close. One atom of the wrong element per 100 billion can shift the electrical properties of every chip cut from that crystal. Two Japanese companies, Shin-Etsu and SUMCO, produce over 50% of the world's 300mm semiconductor wafers. A single wafer sells for $150 to $300. A finished AI chip cut from it sells for over $30,000. China's largest silicon wafer maker, Zhonghuan, serves the solar panel market at six nines of purity. Semiconductor grade requires eleven. Japan has held that gap for 40 years. You can melt silicon anywhere. But you cannot grow a perfect crystal without decades of process knowledge.

Yes, that is not correct. We do CPT, SFT, and RL after porting weights over to a new architecture. As said in the other response, we have trained models from scratch with even larger architectural variants (ex: not sparse attention) you can't use in this way. With additional fundraising, we intend to train truly from scratch.

These two things are about the same size "2nm" transistor gate pitch : 42nm Flagellum motor : 45nm
