Grok Build vs. Claude Code and Codex: Early users have torn xAI's tool to shreds
Elon Musk personally addressed the community asking for criticism of the new Grok Build tool. The response he received was not just feedback, but a veritable avalanche of disappointment. Developers who paid for access to the premium xAI product conducted their own tests and comparisons with competitors. The results were disheartening for Musk's creation.
What is Grok Build and why did it fail to impress?
Grok Build is an agentic CLI tool from xAI, launched in beta in May 2026. It runs from the terminal and is available only to SuperGrok and X Premium Plus subscribers for a hefty $300 per month, placing it in the same price range as Claude Code and GitHub Copilot. The tool is based on the Grok 4.3 beta model with an architecture of 16 agents and a context window of 2 million tokens. However, as practice has shown, impressive specifications do not guarantee quality results.
The loudest complaint from the professional community is a catastrophic lag in quality and task execution speed. One developer conducted a direct experiment: Grok Build toiled on implementing a project for nearly two days. The same workload was given to OpenAI Codex, which completed the task in six hours, advancing twice as far. Another user reported that Grok would enter endless loops for thirty minutes, while Opus from Anthropic solved the same problem on the first try.
Ecosystem and pricing issues
Beyond code quality, developers are actively criticizing the product's ecosystem. The main complaint is the lack of a full-fledged desktop application, similar to Claude Cowork. Users note that Claude's strength lies in its integration into all workflows, not just code writing. Among the requests are: releasing an open-source version during the beta testing period, implementing full loop skill functionality, creating a /goal command for stable autonomous agent operation, and a built-in ability to demonstrate the software being created.
A separate wave of criticism targeted the cost. The mandatory tie-in to the expensive SuperGrok plan, strict token limits, and only 15 minutes of Grok Premium access per day — these conditions baffle specialists. Many fear that xAI might repeat Claude's fate and leave Europe, further narrowing the audience.
The irony of the situation is that Musk, while requesting criticism, accompanied his post with a repost of an enthusiastic fan review. This sparked sarcastic comments and was called a "special kind of self-confidence." However, part of the audience remains loyal, noting the team's rapid iterations and believing that Grok Build will become the best tool on the market.
Expert opinion: For now, Grok Build looks like a raw product trying to compete with mature solutions, possessing only a theoretical advantage in context. The market for agentic developer tools is ruthless: here, people pay not for promises, but for results. If xAI cannot quickly resolve issues with stability and inference speed, the project risks remaining a niche experiment, despite the founder's loud name. The current user feedback is not hate, but a cold shower of reality for marketing claims.
