In a recent LinkedIn post, Linas Beliūnas discusses a surprising observation regarding Chipotle’s AI customer support assistant, Pepper, highlighting its unexpected proficiency in handling complex technical queries.
Beliūnas shared an anecdote where Chipotle’s AI was asked to reverse a linked list in Python, a common computer science interview question. To his astonishment, the chatbot provided a correct code solution, moving beyond its typical function of offering menu recommendations.
“Someone asked Chipotle’s support assistant Pepper how to reverse a linked list in Python. It answered correctly. Not burrito recommendations. Actual code.”
The Unexpected Leap in AI Functionality
Linas Beliūnas expressed his surprise at this development, noting that such a capability was far from his expectations for a fast-food chain’s AI assistant. He frames this as a significant marker in the current state of artificial intelligence.
“A fast-food chatbot quietly passing a classic computer science interview question wasn’t on my 2026 bingo card,” Beliūnas stated on LinkedIn, underscoring the rapid and often unforeseen advancements in AI technology.
AI’s Evolving Role in Customer Service
The observation by Beliūnas suggests a broader trend where AI customer service tools are being equipped with more sophisticated functionalities. While many consumers might expect AI chatbots to handle FAQs and basic inquiries, the ability to generate and understand code points to a more advanced integration of AI.
According to Beliūnas, this incident signifies a potential tipping point for AI integration, suggesting we are reaching “peak AI.” This implies that the capabilities of AI systems are rapidly expanding into domains previously considered exclusive to human expertise.
“We’re at peak AI now.”
Implications Beyond Fast Food
While the example is specific to Chipotle, Beliūnas implies that the underlying technology and the trend it represents have wider implications. The capacity for a customer-facing AI to accurately solve coding problems indicates that AI models are becoming more versatile and powerful.
Beliūnas’s post also includes a personal note, directing readers to a separate link about how he utilizes AI to enhance his own productivity, suggesting a personal interest in leveraging advanced AI tools for business operations.

His observation serves as a reminder for businesses and individuals alike to stay informed about the accelerating pace of AI development and its potential impact across various industries.
