Elon Musk says he's making his AI chatbot open-source — and takes another swipe at OpenAI

• Elon Musk posted on X that his startup's AI, Grok, will go open-source this week. 
• It's unclear what aspects of Grok will be made open to the public. 
• The post comes days after Musk sued OpenAI, accusing it of abandoning its original mission to benefit humanity. 

Elon Musk said on Monday that his ChatGPT competitor "Grok" will go open-source this week — and took yet another swing at rival OpenAi.

"This week, xAI will open-source Grok," Musk announced in a post on X (formerly Twitter).

It's unclear what parts of Grok's source code will be available to the public. So far, Grok has only been available to Premium+ subscribers on X.

Launched in November, the xAI chatbot was created as what Musk calls a more politically neutral and sarcastic version of ChatGPT.

It also leverages X to generate real-time responses.

Musk's move to go open-source with Grok comes just over a week after the billionaire sued OpenAI, accusing it of abandoning its original mission to benefit humanity by partnering with one of the largest tech companies in the world.

Musk's lawyers argued that the partnership transformed OpenAI into a "closed-source de facto subsidiary" of Microsoft. This is causing the company to make decisions based on maximizing profits for Microsoft, his lawyers alleged.

A few days after the lawsuit was filed, OpenAI posted a series of emails that indicated Musk wanted to merge Tesla with OpenAI. In the email exchange, Musk also agreed that OpenAI would have to shift to a for-profit model and said the startup would need "billions per year immediately."

Musk commented in a reply to his post about Grok going open source that "OpenAI is a lie."

Musk and his lawyers did not respond to requests for comment.
