What is Grok?

Grok (now Grok 2) is an artificial intelligence (AI) chatbot and research assistant developed by Elon Musk’s x,AI, which is designed to respond to users’ text prompts with humor and sarcasm.

As x.AI notes in the announcement blog post, Grok is “intended to answer almost anything” and is “designed to answer questions with a bit of wit.” It also has access to real-time data taken from posts made on X (formerly known as Twitter). 

The chatbot, originally launched in November 2023, was inspired by the sci-fi comedy, The Hitchhiker’s Guide to the Galaxy and was originally powered by X.AI’s frontier large language model (LLM), Grok-1 before it was replaced by Grok-2 in August 2024.

The Grok 2 family of language models includes the Grok-2 and Grok-2 mini, which are both available to users via the X platform. Both models demonstrate enhanced multimodal capabilities like image generation, plus better problem-solving and reasoning than the previous generation. Notable features include the ability to process visual information such as documents, diagrams, charts, screenshots, and photographs (since Grok 1.5) and the ability to generate images.

Upon its release, xAI reported that an early version of Grok 2 was tested on the LYMSYS leaderboard and actually outperformed Claude 3.5 Sonnet and GPT-4 Turbo.

Compared to the original version of Grok, Grok 2 features enhanced reasoning and versatility in performance across different tasks, from question answering to solving code problems.

Since its release, Grok 2 has been quite controversial. Its lack of content moderation has enabled users to generate images that some may find offensive. This has brought debates about the ethical implications of this technology.

What is Grok

Key Takeaways

  • Grok is x.AI’s humorous AI assistant.
  • The chatbot is designed to respond to user’s text prompts with humor and sarcasm.
  • It uses real-time data taken from X (formerly known as Twitter) to respond to user inputs.
  • Elon Musk has summarized Grok as a chatbot that’s “based & loves sarcasm.”
  • Grok’s less restrictive content moderation opens the door for greater misuse.

What Differentiates Grok from Other AI Assistants?

At this stage in development, the key differentiator between Grok and other AI assistants like ChatGPT with GPT-4o and Claude 3 is that Grok is connected to real-time data taken from the social media platform X. This helps to improve the accuracy of Grok’s responses.

According to the X website, content, including posts, user interactions, inputs, and Grok results, are used to help train and fine-tune the chatbot. While users are opted in by default, they can opt out of having their activities scraped via their account settings.

While the nature of this training data hasn’t been publicly disclosed, being able to access the high volume of conversational content on X and potentially some of the vendor’s proprietary data behind the scenes could make the chatbot a significant player in the market.

In addition, Grok’s emphasis on humor and wit is also a significant point of differentiation from competitors like GPT4 and Claude 2, which have focused on interacting with users in a conversational but restrained manner and minimizing harmful outputs. As Musk explained in a post on X, Grok is “based & loves sarcasm.”

As a result, the playful approach of Grok has the potential to entertain users with witty responses in a way that replicates the lighthearted nature of everyday human interaction.

How Does Grok Perform Against Other LLMs?

So is Grok as good as ChatGPT? After the launch of Grok 2, x.AI’s chatbot has become one of the most promising competitors in the market.

Grok 2 has performed extremely well on key benchmarks like MMLU and HumanEval. For instance, on MMLU, Grok 2 scores 87.5%, compared to 86.5% for GPT-4 Turbo, 85.7% for Claude 3 Opus, 85.9% for Gemini Pro 1.5, and 88.7% for GPT-4o. Likewise, on HumanEval, Grok 2 scores 88.4%, compared to 87.1% for GPT-4 Turbo, 84.9% for Claude 3 Opus, and 90.2% for GPT-4o.

These metrics suggest that Grok 2 can keep up with even the best models in terms of performance. As xAI states, “they [Grok-2 and Grok-2 mini] achieve performance levels competitive to other frontier models in areas such as graduate-level science knowledge (GPQA), general knowledge (MMLU, MMLU-Pro), and math competition problems (MATH).”

It’s also worth highlighting that Grok was relatively late to the AI race, so it’s impressive the model has come a long way in such a short space of time to compete against more entrenched providers like OpenAI.

Research Team Behind Grok

xAI launched in March 2023 and is composed of experienced AI researchers who’ve previously worked at organizations and institutions, including OpenAI, DeepMind, Google Research, and the University of Toronto.

This includes Ibor Babuschkin, Manual Kroiss, Yuhuai Wu, Christian Szegedy, Jimmy Ba, Toby Pohlen, Ross Nordeen, Kyle Kosic, Greg Yang, Guodong Zhang, Zihang Dai, Xiao Sun, Fabio Aguilera-Convers, Ting Chen, and Szymon Tworkowski.

The company’s researchers have contributed to a wide range of innovations in the space, including GPT4, GPT 3.5, AlphaStar, AlphaCode, Inception, Minerva, the Adam optimizer, batch normalization, layer normalization, Transformer-XL, auto formalization, and batch size scaling.

Overall, the highly experienced team of researchers behind Grok and the project’s proximity to the X platform suggest that Musk’s AI startup will remain a key vendor in the generative AI market for the foreseeable future.

The Potential for Harmful Output

As an LLM-driven chatbot, Grok faces the same challenges as all other language models. It can be prompted or jailbroken to produce harmful, discriminatory, or illegal content.

However, it’s unclear whether Grok’s emphasis on providing humorous and witty responses to user prompts will amplify the risk of creating content that some users may find offensive.

As xAI notes, Grok has a “rebellious streak” and will answer questions rejected by other AI systems, which means that there are potentially more opportunities for offensive content to be generated.

On X, there are also countless posts of X being used to create questionable images, from public figures like President Trump and Kamala Harris being deepfaked and depicted holding guns to Barack Obama being depicted doing cocaine.

Other Challenges: Bias from X

Another potential risk factor is the use of real-time data from X. Historically, X, when it was known as Twitter, experienced lots of criticism over the spread of toxicity and misinformation throughout the platform.

For example, Pew Research found that 17% of users have experienced harassment or abusive behavior on the platform, and 33% have seen a lot of inaccurate or misleading information.

This means there is a risk that some of the toxicity and misinformation on the platform could leak into Grok’s training data and create harmful biases and responses. This means a significant amount of content moderation will need to be in place to prevent toxic or inaccurate content from filtering into outputs.

So far, xAI appears to be working to minimize the risk of harmful outputs. The announcement blog post highlights the team is “interested in improving the robustness of LLMs” and “doing our utmost to ensure that AI remains a force for good.” It is actively being advised by Dan Hendrycks, the director of the Center for AI Safety.

The Bottom Line

Now that we’ve looked at Grok’s meaning and key features, it’s important to recognize that x.AI’s answer to ChatGPT will likely remain a key player in the AI race for quite some time.

Grok has quickly become one of the most talked about LLMs on the market. Its connection to Elon Musk and X makes it an important player in the AI race going forward, with all the ingredients necessary to compete against top players like OpenAI and Google.
