As of December 2025, the key difference between ChatGPT and many other AI tools lies in its foundational architecture: ChatGPT is a Large Language Model (LLM) specifically designed for conversational interaction, while other AI tools typically focus on single, defined tasks like image generation or data analysis.
In 2026, ChatGPT, now including multimodal capabilities released throughout the year, continues to excel at understanding and generating human-like text, and can process images, audio and video as inputs. Other AI tools, such as marketing automation platforms like HubSpot or ActiveCampaign, integrate AI features – currently including predictive lead scoring and content optimisation – but these operate as add-ons to existing systems. These platforms utilise AI models, often accessed via APIs from providers like Google Cloud AI available in Australia, to enhance specific functionalities. For example, an Australian SME might use an AI-powered tool within their email marketing platform to A/B test subject lines, but this relies on a separate AI engine. ChatGPT, conversely, *is* the engine. The Australian Privacy Principles (APPs) apply to data processed by all these tools, requiring businesses to ensure compliance when using AI for customer data.
Essentially, ChatGPT functions as a versatile AI ‘brain’, while other tools integrate AI to improve performance within their pre-defined scope.
