Why Elon Musk's AI company 'open-sourcing' Grok matters — and why it doesn't

Elon Musk's xAI has released its Grok large language model as "open source", a move seen as a challenge to rival OpenAI. Grok, a chatbot trained by xAI, is considered competitive with last-generation medium-size models like GPT-3.5. However, the term "open source" in AI is controversial as AI models are created through a complex, largely unknowable process that can't be inspected and improved like traditional code. While xAI's Grok release is an open-weights model, meaning its developers have released its weights or the exact attributes of its neural networks, it excludes other important data like the training dataset and process.

The release of Grok, which has 314 billion parameters, is seen as a positive move, but it's not a game-changer. The model requires hundreds of gigabytes of high-speed RAM to use in its raw form, limiting its accessibility. Questions also remain about Musk's motivations for the release, whether it's a genuine commitment to open source development or a move to challenge OpenAI. If xAI is truly dedicated to open source development, future releases and more transparency are expected.

Key takeaways:

Elon Musk's xAI has released its Grok large language model as open source, aiming to differentiate itself from rival OpenAI.
The concept of 'open source' in AI is complex and arguably not fully achievable due to the nature of machine learning models and the resources required to create or replicate them.
Grok is an open-weights model with 314 billion parameters, making it one of the largest models available for free access, but it requires substantial resources to use in its raw form.
While the release of Grok is seen as a positive move, it's unclear whether xAI is genuinely committed to open source development or if this is a strategic move against OpenAI.
