xAI Now Publishes Daily Grok Build Updates — Here's Where to Track Them

xAI has a dedicated page for tracking daily build version updates to Grok, and Elon Musk just pointed his 200M+ followers directly to it. The move signals that xAI is treating Grok's development cadence more like an open software project — with visible, timestamped progress — rather than the opaque release cycles typical of AI labs.

The timing is notable. According to reporting from sqmagazine.co.uk, Musk confirmed on May 25 that xAI has completed training on Grok V9 Medium — a foundational model with 1.5 trillion parameters, three times the scale of the current v8 small model at 0.5 trillion parameters. Supervised fine-tuning is underway, with reinforcement learning training expected to begin imminently. A public release is targeted roughly two to three weeks from that announcement, putting the window somewhere in mid-June 2026.

The daily build page appears to track Grok Build specifically — xAI's dedicated coding agent — rather than the flagship chat model. That distinction matters: coding agents ship iterative improvements far more frequently than consumer-facing models, and making those changes publicly visible is an unusual transparency play in a field where most labs share little between major version announcements. For developers and power users already relying on Grok for coding workflows, the page offers a real-time view of what's changing under the hood.

With Grok V9 Medium on the horizon and a public changelog already live, xAI appears to be accelerating both its development pace and its communication around it — a combination that will put pressure on competitors to match the cadence or explain why they won't.
