In this March 2024 video, Matthew Berman discusses xAI’s release of Grok-1 base-model weights, architecture and example code under Apache 2.0. He interprets the release partly through Elon Musk’s dispute with OpenAI and offers his impressions of Grok. The released checkpoint was not fine-tuned for dialogue, and its weights do not by themselves provide the live X access associated with a hosted product.

핵심 정리
- xAI released Grok-1 base weights and architecture under Apache 2.0 on March 17, 2024.
- The 314-billion-parameter mixture-of-experts model uses two of eight experts for each token.
- The released checkpoint completed pretraining in October 2023 and was not fine-tuned for dialogue.
- The hosted Grok product and the downloadable base checkpoint are different systems; real-time X access requires a separate integration.
- Berman’s claims about Musk’s motives, model quality and censorship are interpretations or impressions rather than verified conclusions.

Musk, OpenAI and the release
Berman recounts Musk’s criticism of OpenAI and interprets the timing of the release. He comments on the public dispute and reaction.
Matthew Berman reports that xAI released Grok-1 on March 17, 2024, shortly after Elon Musk publicly criticized and sued OpenAI. Berman interprets Musk’s motive as partly competitive pressure and personal animosity; the release announcement does not establish those motives, and the lawsuit’s allegations are not findings of fact.
Berman recaps Musk’s posts criticizing OpenAI’s name and discusses reactions on X. He favors openly available AI models, then comments on public speculation surrounding OpenAI executives. His impressions of their motives and roles are personal commentary, not verified information about internal company decisions.
Grok-1 weights and architecture
Berman examines the download and technical details. xAI released an unfine-tuned base checkpoint with example code under Apache 2.0.
The release contains a 314-billion-parameter mixture-of-experts base model. The xAI repository specifies eight experts, with two selected per token, and provides JAX example code to load and sample from the checkpoint. The download shown in the video is hundreds of gigabytes; substantial memory is required to run the example.
xAI released the associated code and weights under Apache 2.0. The announcement says the checkpoint comes from pretraining completed in October 2023 and was not fine-tuned for a particular application such as dialogue. The release of weights and example code should not be assumed to include all training data or the complete hosted product.
Hosted access and model limitations
Berman discusses Grok’s hosted experience and X data. The release itself does not establish live access or the full training corpus.
Berman says his previous experience with the hosted Grok assistant was merely adequate compared with GPT-4, while he values its access to information from X. That is his informal comparison, not a controlled benchmark. Real-time access is a product integration and does not come automatically with a downloadable base-model checkpoint.
Berman suggests that access to X gives xAI a distinctive data source and discusses changes to Twitter’s API. The release announcement describes training on a large amount of text but does not disclose a complete dataset, so the video does not establish exactly which X posts were used or what proportion they represented.
He emphasizes that the released model is a base checkpoint and believes it has little censorship. Lack of dialogue fine-tuning does not prove an absence of safety behavior or establish how the model will respond to every request; outputs also depend on any later fine-tuning and the system around the model.
Berman closes by inviting viewers to request a more complete test. The release is significant for developers who can work with the large checkpoint, but his remarks do not provide a systematic evaluation of its capabilities or safety.
