Elon Musk Announces Grok 2.5 is Now Open Source

Elon Musk has announced that different model weights for Grok 2.5 are now available as open source.

Musk’s AI company, xAI, has made the model weights for Grok 2.5, one of last year’s most powerful models, accessible on the open-source platform Hugging Face.

In an official post on his X account, Elon Musk stated, “Grok 2.5, our best model from last year, is now open source.” He also announced that Grok 3 would become open source in about six months.

Despite the release, controversy continues. AI engineer Tim Kellogg criticized Grok’s license, saying it “contains some private, anti-competitive conditions.” This has raised questions about how freely Grok can actually be used under its open-source label.

This year, Grok has been the subject of controversy, particularly for its answers on racist conspiracy theories on X. It even garnered strong backlash for identifying itself as “MechaHitler.” Following the public outcry, xAI was forced to share the system’s directive commands on GitHub.

Although Elon Musk has introduced the latest version, Grok 4, as an “AI in pursuit of maximum truth,” it is still rumored that the model consults Elon Musk’s social media posts before responding to controversial topics. This continues to fuel doubts about whether Grok is truly an independent AI.
