Is ChatGPT Plus worth it?
ChatGPT Plus ($20/month) is worth it if you use GPT-4o more than 30 times per day. It includes unlimited access to GPT-4o, web browsing, DALL-E image generation, and custom GPTs. For light users (under 20 messages/day), the API is more cost-effective.
What's the difference between ChatGPT Plus and API?
ChatGPT Plus is a $20/month subscription with a web interface and includes browsing, DALL-E, and GPTs. The API is pay-per-use (variable cost) and requires coding to integrate. Plus is for personal use; API is for developers building applications.
Can I use GPT-4 without ChatGPT Plus?
