Musk announces xAI 4.0, promises this restart will finally include a plan

Elon Musk on Thursday announced xAI 4.0, describing it as a "complete restart of the previous three restarts" and the first version to ship with what he called "an actual plan-shaped thing." The company said the new iteration would be "strategy-complete by design," after prior versions were classified internally as "vibes-forward" and "lightly intentioned."

“One research note estimated that if the current pace continues, xAI could reach xAI 9.0 by early 2027 without ever exiting beta.”

In a presentation streamed from an undisclosed hangar, Musk said xAI 4.0 is being developed using a "zero-based planning framework" in which no assumptions are carried over from previous attempts, including code, roadmaps, or remembered mistakes. "We found a lot of legacy confusion debt," he said, citing an internal audit that identified 137 overlapping visions and 41 mutually exclusive mission statements.

A spokesperson confirmed that the new plan spans 762 slides, of which 59 are labeled "TBD" and 118 are dedicated to explaining why earlier plans were not technically plans. According to an internal memo seen by reporters, employees are required to "read, internalize, and emotionally align" with the document at least 4.0 times per quarter.

The company said it would continue its partnership with AI coding tool Cursor, which will now be tasked with automatically refactoring xAI’s roadmap every 72 minutes. Engineers familiar with the system said Cursor has already generated 9,842 versions of the plan since Monday, with a compliance dashboard tracking which plan is currently considered canonical.

Analysts at Morgan Stanley noted that xAI’s decision to relaunch its relaunch could create "second-order optionality in the pivot cycle," projecting a 37.5% year-on-year increase in strategic do-overs. One research note estimated that if the current pace continues, xAI could reach xAI 9.0 by early 2027 without ever exiting beta.

Internally, xAI 4.0 introduces a new metric, Plan-Adjusted Execution Velocity (PAEV), which measures how quickly the company can move relative to how unfinished its plan remains. An OKR document reviewed by this outlet sets a target of "sub-3% plan completion with triple-digit PAEV" by Q4.

According to people familiar with the matter, the next step is a phased rollout in which xAI will first announce that it has a plan, then announce that the plan is being updated, and finally announce xAI 5.0 as a "clean-sheet implementation" of the lessons learned from planning xAI 4.0. A timeline for these announcements will be determined once the company finalizes its roadmap for finalizing the roadmap.
