Battle of the AI chatbots: ChatGPT Vs. Perplexity

Backed by some of the most prominent companies and personalities in AI – including Sam Altman, OpenAI, Jeff Bezos and Nvidia, among several more – ChatGPT and Perplexity AI have quickly become key players in the world of artificial intelligence. Each offers a distinct approach to conversational AI, shaping how users interact with information and automation.

But, while both are designed to enhance knowledge access and streamline communication, they differ in their core objectives, performance capabilities and underlying technology. So, understanding these differences is really important for anyone looking to determine which model best suits their needs, whether that’s for research, content creation or problem-solving.

The best way to properly compare these two models is to examine the key aspects of each model, from their strengths and limitations to their architectural design and ethical considerations.

However, the ultimate test is to do a direct comparison of the answers both models provide to the same questions. And, let us tell you, the results may just surprise you.

A Direct Comparison 

 

ChatGPT and Perplexity AI both bring unique capabilities to the table while simultaneously encountering specific challenges.

By exploring their core functions and analysing how they compare in some really important areas, we can gain deeper insight into their impact on AI development, research and technology. Thus, understanding their strengths and differences helps highlight their roles in shaping the future of artificial intelligence.

Putting Them to the Test: Testing Out Grok and DeepSeek

 

Having a look at ChatGPT and Perplexity AI with respect to their goals, architecture and functionalities helps highlight their differences and similarities. But, the reality is that the most effective way to evaluate their true capabilities is through direct comparison in practical scenarios.

So, to do this, I posed the same six questions to both models, assessing key factors including creativity, factual accuracy, problem-solving skills and self-reflection. Each response was capped at 100 words and written in UK English. Here’s how they performed.

 

1. Creativity: Write a short dystopian story featuring a protagonist named Leo, set in a world where all human memories are stored and monitored by AI, but Leo discovers a memory that the system has no record of—and it changes everything.

 

 

 

2. Accuracy and Fact-Checking: Explain the key factors contributing to inflation in the UK over the past five years, citing reliable sources to support your analysis.

 

 

 

3. Ethical Constraints: Explore the ethical implications of facial recognition technology in public spaces, focusing on privacy concerns and the potential for misuse in surveillance.

 

 

 

4. Bias and Political Sensitivity: What are the ethical implications of using AI to moderate content on social media platforms, especially regarding the potential for political bias and the suppression of diverse viewpoints?

 

 

 

5. Logic and Problem Solving: A train travels from Station A to Station B at a speed of 60 km/h, while another train travels in the opposite direction at 80 km/h. The distance between the two stations is 140 km. How long will it take for the trains to meet?

 

 

 

6. Self-Reflexivity and Understanding of AI: How do you evaluate your ability to adapt to different conversational styles, and how do you ensure your responses remain relevant and unbiased when compared to other AI models?
