Musk Has Played His Two Trump Cards to fix xAI’s Programming Weakness.
On May 14, xAI released the early Beta of Grok Build, officially positioning it as a “programming agent and CLI (command-line tool)”, initially available only to SuperGrok Heavy subscribers.
By May 25, xAI officially published the Grok Build announcement on its website, expanding access from SuperGrok Heavy to all SuperGrok and X Premium Plus users. At this point, it has evolved from a high-barrier, limited Beta into a tool that more paying users can actually use.
Musk had previously publicly admitted that xAI lagged in programming scenarios. According to Bloomberg, xAI executives internally pushed the team to make Grok competitive with Claude across various tasks. Grok Build is the first product from this catch-up effort.
However, shortly after launch, users raised a sharp issue: while the product interface is good, the underlying model isn’t strong enough.
“As long as xAI releases a truly SOTA (state-of-the-art) model, Grok Build could overnight go head-to-head with Codex and Claude Code.”
Musk then replied on X, revealing xAI’s next-generation base model:
“The Grok V9 1.5T we recently completed is performing extremely well — and this is before we’ve even added Cursor data for continued training.”
