How We Tested These AI Models
To ensure a fair and accurate AI model comparison, we tested each AI model across multiple real-world applications. Our goal was to evaluate how well each AI performs in different scenarios that users typically encounter.
We started by designing a structured set of prompts tailored to measure key capabilities. These included creative writing tasks, factual research queries, conversational depth tests, and technical problem-solving challenges. By applying the same prompts to each model, we were able to compare responses side by side, measuring accuracy, fluency, and usability.
Additionally, we considered factors such as response speed, ease of integration into workflows, and limitations in specific use cases. Through this testing approach, we gained valuable insights into where each AI model excels and where it may fall short.
- Content generation: Evaluating creativity, coherence, and structure in long-form writing.
- Research & fact-checking: Assessing the accuracy and sourcing of responses.
- Conversational ability: Measuring fluency, natural language understanding, and contextual awareness.
- Technical problem-solving: Testing code generation and complex reasoning capabilities.
By running identical prompts through each AI model, we gained valuable insights into their strengths and limitations, allowing us to present a balanced breakdown of their capabilities.

Limitations & Challenges of AI Models
While AI models continue to advance, they still face significant limitations and challenges that users should be aware of. One of the most pressing issues is hallucination, where AI generates confident but factually incorrect or misleading information. This is particularly problematic in research and business applications where accuracy is critical. Even models like Perplexity, which prioritize citations, are not immune to misinformation.
Another major challenge is bias in AI outputs. Since these models are trained on vast datasets sourced from the internet, they can unintentionally reinforce stereotypes, political biases, or misleading narratives. Companies like OpenAI, Anthropic, and Google are actively working on improving fairness and reducing bias, but complete neutrality remains an ongoing challenge.
Lastly, over-reliance on AI can be risky, especially in decision-making. While AI models are excellent for automating tasks and enhancing productivity, they should not replace human judgment in areas requiring nuance, creativity, and ethical considerations. Users must remain critical thinkers, verifying AI-generated insights rather than accepting them blindly.
