Musk unveils $20B TeraFab chip project

On March 22, 2026, Musk said Tesla and SpaceX want to build TeraFab, a joint semiconductor campus in Austin that would keep more of the chip stack on one site. He cast it as a way to feed Tesla vehicles, Optimus robots, and space compute, but gave no production timeline and said the companies will still buy chips from TSMC, Samsung, and Micron.

// ANALYSIS

Hot take: this is a vertical-integration moonshot first and a fab plan second. If TeraFab ever gets built, it could shorten chip iteration loops for Musk's hardware stack; if not, it still signals how badly Tesla and SpaceX want to control their AI silicon destiny.

–A single-campus flow from chip design through packaging and test would cut a lot of handoffs.
–The 100 to 200 GW terrestrial target, plus the space-compute vision, looks like a long-range aspiration, not a near-term schedule.
–The hard parts are process control, yields, tooling, and semiconductor talent; money alone does not solve those.
–Keeping TSMC, Samsung, and Micron in the mix makes TeraFab a hedge, not a replacement.

Plannotator 0.19.24 adds Amp support and configurable storage

Plannotator 0.19.24 is a substantial release that expands the tool beyond Claude Code with native Amp support, adds a `PLANNOTATOR_DATA_DIR` override so users can move the default `~/.plannotator` data directory, introduces Auto Mode in the permission selector for newer Claude Code versions, and fixes a Pi approval crash after plan acceptance. The update folds multiple stacked PRs into one release and pushes the project further toward a multi-agent review layer rather than a single-agent hook utility.

Grok Build widens access, adds subagents

xAI’s Grok Build is an early-beta terminal coding agent with plan-review-approve flows, parallel subagents, worktree isolation, and support for plugins, hooks, skills, and MCP. The latest improvements make it feel less like a demo and more like xAI’s bid to compete seriously in the AI coding CLI race.
