As of December 2025, ChatGPT functions as a large language model (LLM) capable of generating text-based content, including blog post ideas, by predicting the most probable sequence of words based on the input prompt and its training data.
In 2026, OpenAI’s ChatGPT – available in Australia via subscription tiers including ChatGPT Plus and Team – now includes features like custom instructions and GPTs. GPTs allow users to create tailored versions of ChatGPT for specific tasks; a GPT designed for ‘Australian SME Blog Ideas’ could be configured with parameters like target audience demographics, industry keywords relevant to Australian businesses, and preferred blog post formats. The system operates by receiving a prompt (e.g., “Generate 10 blog post ideas for a plumbing business targeting homeowners in Melbourne”), processing it through its neural network, and outputting text that aligns with the prompt and its internal knowledge base. OpenAI’s data centres supporting Australian users are located in Sydney and Melbourne, ensuring relatively low latency. Currently, the model’s knowledge cut-off is early 2023, meaning it won’t have information on events after that date unless specifically provided in the prompt. Announced for 2027 is an update to extend this knowledge cut-off and improve real-time data access.
Essentially, ChatGPT generates blog post ideas by statistically analysing and recombining information from its vast dataset based on the user’s input.
