X.ai introduces Grok-1.5, a significant upgrade to its generative AI model, set to power X’s Grok chatbot

  • X.ai reveals Grok-1.5, an enhanced version of its generative AI model, set to power X’s Grok chatbot.
  • Grok-1.5 demonstrates significant improvements in reasoning, particularly in coding and math-related tasks, as evidenced by benchmark results.
  • The model boasts an expanded context window, allowing it to process contexts of up to 128,000 tokens, leading to better comprehension of longer conversations.
  • Historically known for engaging with taboo topics and exhibiting a rebellious nature, it’s unclear if Grok-1.5 brings changes in these aspects.
  • Grok-1.5 will soon be available for early testing on X, introducing several new features, including thread summarization and content suggestion.
  • X.ai’s decision to open source Grok-1 and expand access to the Grok chatbot signifies a broader market strategy aimed at attracting more users, particularly those on the $8-per-month Premium plan.

Main AI News:

X’s Grok chatbot is poised for an upgrade with the imminent arrival of Grok-1.5. Elon Musk’s pioneering AI venture, X.ai, has unveiled its latest iteration, Grok-1.5. Set to drive the social network X’s Grok chatbot in the foreseeable future— as stated in a recent blog post—Grok-1.5 appears to represent a significant advancement over its precursor, Grok-1, based on the published benchmark results and specifications.

According to X.ai, Grok-1.5 boasts “enhanced reasoning,” particularly in coding and math-related tasks. The model has shown remarkable improvement, doubling Grok-1’s score on the widely recognized mathematics benchmark, MATH, and achieving a more than 10% increase on the HumanEval test, which assesses programming language generation and problem-solving capabilities.

While these results are promising, it remains challenging to forecast how they will translate into real-world applications. As discussed previously, commonly used AI benchmarks often fail to accurately reflect how individuals interact with models in everyday scenarios.

One notable enhancement expected to yield tangible benefits is Grok-1.5’s expanded capacity to comprehend context compared to its predecessor. With the ability to process contexts of up to 128,000 tokens, Grok-1.5 surpasses Grok-1 in this regard. A larger context window enables the model to retain information from longer conversations, thereby enhancing its understanding of incoming data.

[Grok-1.5 can] utilize information from substantially longer documents,” X.ai states in the blog post. “Furthermore, the model can handle longer and more complex prompts while still maintaining its instruction-following capability as its context window expands.”

What has historically distinguished X.ai’s Grok models is their willingness to engage with topics typically avoided by other generative AI models, such as conspiracies and controversial political ideas. Additionally, these models have been known to respond with a “rebellious streak” and even use rude language if requested.

It remains uncertain what alterations, if any, Grok-1.5 introduces in these aspects, as X.ai does not address them in the blog post.

Grok-1.5 is set to be available soon for early testers on X, accompanied by “several new features.” Musk has hinted at potential features including thread summarization, content suggestion for posts, among others, although it remains to be seen when these will materialize.

This announcement follows X.ai’s decision to open source Grok-1, albeit without providing the necessary code for fine-tuning or further training. Musk has also recently indicated that more users on X—specifically those subscribed to X’s $8-per-month Premium plan—will gain access to the Grok chatbot, which was previously exclusive to X Premium+ customers paying $16 per month.


The unveiling of Grok-1.5 signifies a notable advancement in X’s AI capabilities, promising enhanced performance and expanded features for users. This move aligns with X.ai’s strategic objectives to broaden its market reach and solidify its position as a leading provider of generative AI solutions. As the market for AI-driven chatbots continues to evolve, X’s innovative approach positions it favorably to meet the growing demands of users seeking advanced conversational AI experiences.
