In this , Tom Kurfess, 鈥淐yber Kyle鈥� Saleeby, both of Georgia Tech, and I (Stephen) talk about OpenAI鈥檚 ChatGPT 鈥� or, the hottest bot in town. The large language model (LLM) is both highly conversational and controversial. Let鈥檚 鈥渃hat鈥� GPT, and break down what an LLM is, how to use it, and its utility to manufacturing.
First, to clear the air: no, ChatGPT won鈥檛 (and can鈥檛) replace manufacturing jobs. But why?
Large language models leverage machine learning and words. They provide the most statistically relevant string that follows a given prompt. To do so, tools like ChatGPT use a massive dataset of text taken from the internet up to 2021, when it was released. It knows nothing of current events, and cannot predict the future.
In a sense, it鈥檚 more like 鈥渁rtificial interpolation.鈥� Its responses are only as good as our human writing abilities.
These tools are excellent for summarizing long texts or generating code snippets but could be better for more complicated tasks. LLMs may not 鈥渓isten鈥� to a prompt, or flat-out lie, as they focus more on syntax and less on semantics. To be effective, users must be conversational, as the more input is given, the better the results will be.
Exercise caution when using LLMs. Despite safeguards, they can provide dangerous information. For example, ChatGPT refuses to answer illegal or hazardous questions, but clever rephrasing can work around its guardrails. ChatGPT, Google鈥檚 Gemini, and Microsoft鈥檚 Copilot often pick up on these tricks, but not always.
Even with safer models, users should avoid offering sensitive information. Models use new prompts to train further, which means all information is unprotected. As usual, use human intuition and skepticism when chatting with robots.
Do not ask ChatGPT for G-code 鈥� we鈥檝e tried, and it's bad. Domain-specific jobs like CNC programmers are safe from robo-replacement. However, companies are quickly adding this technology into manufacturing tools. In the future, an AI may be able to say, 鈥淭ry these feeds and speeds,鈥� or, 鈥淯se this tool. And, by the way, you鈥檙e running low on material. Reorder some more?鈥� It鈥檚 a promising future, where AI is not a replacement but a force multiplier.
Even if ChatGPT is a little dumb, it is the first entry into commercial AI. AMT sees artificial intelligence as a central part of manufacturing鈥檚 future, so staying relevant is vital.
