Terafab gets a test chip window and a volume date

The Die Brief Desk, after @SawyerMerritt

May or June is the window for the first test chip, and Q3 2028 is the early volume date, but the filing names no chip, node, or customer.

The machinery comes online in the first half of next year, before the test chip and the volume window.

The filing also carries a Q2 2028 subhead, so the date is a statement rather than a measured milestone.

The constraint is the fab, not the design. Until a die is measured, Tesla cannot show that its own silicon can be made, let alone sold.

The document leaves out the chip name, node, power, price, and benchmark. It also omits whether the test chip is a test vehicle or a production part.

A buyer or foundry partner should treat the timeline as a commissioning schedule, not a product commitment.

The piece tracks a commissioning schedule for Terafab, noting that the test chip and volume dates are statements rather than measured milestones, and that no chip name, node, or customer is named.

After @SawyerMerritt. We did not report this. The pictures, if any, are theirs.
