GPT 3.5 vs. GPT 4: What's the Difference?
How-To Geek, March 31st, 2023
If you've been following the rapid development of AI language models used in applications like ChatGPT and Bing AI chat, you're likely familiar with OpenAI's GPT-3 and GPT-4. But what about GPT 3.5, the stepping stone between these two AI titans? How does it compare to the latest GPT 4?
GPT 3.5 is, as the name suggests, a sort of bridge between GPT-3 and GPT-4. OpenAI hasn't really been particularly open about what makes GPT 3.5 specifically better than GPT 3, but it seems that the main goals were to increase the speed of the model and perhaps most importantly to reduce the cost of running it.
Interestingly, what OpenAI has made available to users isn't the raw core GPT 3.5, but rather several specialized offshoots. For example, GPT 3.5 Turbo is a version that's been fine-tuned specifically for chat purposes, although it can generally still do all the other things GPT 3.5 can.
