What Is ChatGPT?
ChatGPT is a family of AI models developed by OpenAI. It can write content, answer questions, create code, generate ideas, and assist with almost any text-based task. Different versions of ChatGPT are optimized for different jobs.
Meet the Main ChatGPT Models
Let’s break down the most important models you need to know as a business owner or mortgage pro:
| Model | Best For | Strengths | Limitations |
|---|---|---|---|
| GPT-4o (aka o4) | All-purpose: SEO blogs, local pages, coding, support | Fast, accurate, handles code, content & marketing | Best results come with well-structured prompts |
| GPT-4o-mini-high | Quick SEO tasks, social posts, outline generation | Balance of quality and speed | Not suited for full blog posts or detailed code |
| GPT-4o-mini | Meta titles, short tweets, quick tasks | Fastest and cheapest | Not ideal for complex logic or writing |
| GPT-3.5 (o3) | Rough drafts or idea generation | Very fast, low cost | More prone to factual errors, not great with structure |
