Elon Musk teases official Grok CLI for developers as AI rivalry with Anthropic heats up

Elon Musk has teased the official Grok CLI for developers aiming to outcompete Anthropic Claude in the agentic coding race.

The announcement comes as the founder of xAI responded to a user’s post about frustration with Anthropic popular terminal-based AI coding tool, which handles file edits, shell commands, and complex codebases right in the developer's workflow.

The user wrote in a post, “Hey @elonmusk, if you hate Anthropic so much, make a Grok CLI and I’ll cancel my Anthropic subscription today.”

Elon Musk replied, “Coming soon.” without citing any further details regarding date, pricing and features.

Community versions like superagent-ai/grok-cli already exist using xAI's API, and Musk's tease hints at an official version to compete in the agentic coding space.

The major announcement came a day after Elon Musk accused Anthropic of stealing training data at a massive scale.

Taking to X, the CEO of SpaceX wrote, “Anthropic is guilty of stealing training data at massive scale and has had to pay multi-billion-dollar settlements for their theft. This is just a fact.”

Prior to those claims, Anthropic shared disturbing findings, accusing Chinese AI firms, such as DeepSeek, Moonshot AI, and MiniMax of using Claude for unauthorized model training.

According to the US-based artificial intelligence company, these start-ups used a technique called “distillation” in which these AI firms extract and leverage outputs from a more powerful AI system to rapidly boost the performance of low-scale models.

“These labs created over 24,000 fraudulent accounts and generated over 16 million exchanges with Claude, extracting its capabilities to train and improve their own models,” Anthropic posted.
