AI Commentary
ChatGPT is the product that ignited the mainstream AI adoption wave and remains the most recognized AI assistant globally. GPT-4o's multimodal capabilities—processing text, images, voice, and video—place it at the frontier of general-purpose AI. The Custom GPTs marketplace enables organizations to deploy branded AI assistants without code. Enterprise adoption requires careful attention to data privacy policies, as OpenAI's default training practices differ from API usage.
Perplexity has carved a distinct niche as the AI tool for research and fact-finding, competing more with Google Search than with ChatGPT. Its citation-first approach provides source transparency that general-purpose chatbots lack. The Pro tier's model choice—toggling between GPT-4o, Claude, and Perplexity's own Sonar—offers unusual flexibility. For generative tasks like writing or coding, purpose-built tools outperform it significantly.
