1. ChatGPT Free: The No-Cost Entry Point

ChatGPT Free is the starting line in the AI race for SMEs. Powered by GPT-3.5, it offers a glimpse into the future without any financial commitment. However, it’s important to note that data inputted may be used in OpenAI’s training, and the information provided only goes up until 2021, potentially limiting its application for current events or data analysis.

• Scalability & Cost: Ideal for initial exploration, but its limitations in updates and data usage could hinder scalability.
• Customisability: Minimal. It serves more as a general tool rather than one that can be tailored to specific business needs.
• Complexity to Setup and Manage: Virtually zero. Its ease of access is a major plus for businesses making their first foray into AI.
• Upfront and Ongoing Cost: Free, making it an attractive option for businesses on a tight budget.

2. ChatGPT Plus: The Premium Upgrade

For SMEs looking to delve deeper, ChatGPT Plus offers advanced features like access to GPT-4, internet browsing capabilities, plugins, data analysis, and custom GPTs for $20 USD / month.
