There’s been a lot of confusion about what the new OpenAI gpt-oss models are and what they’re good for. So let’s clear the air a bit.
First and foremost, it is NOT a drop-in ChatGPT replacement. It is far too small and has far too little knowledge to be a good all purpose general foundation model. Big foundation models like O3 or Gemini or Claude measure in the trillions of parameters. An open model you can run on your laptop is going to be several orders of magnitude smaller and less knowledegable – otherwise you would need a data center to run it.
Good luck getting a DGX 100 Cluster through the TSA baggage scanner.
What that means is that small, open models are fluent and skilled at working with language, but they lack knowledge. Without some form of external context like web search capabilities or you providing lots of data, they are going to have absurdly high hallucination rates. This is true of all models that you can run self-contained on a laptop.
So what is it good for if you can’t use it as a general ChatGPT replacement?
They’re great for working with data YOU provide. If you need to rewrite something, or summarize it, or potentially translate it, AND you’ve provided all the data, they will work phenomenally well.
They’re fantastic for use with agents and code, where you are doing the same task over and over again, like scoring sentiment or tone in a big pile of articles one at a time. It would cost you hours of copy pasting or thousands of dollars in API costs to do that with a cloud-based solution – and it only costs you electricity and time to do it with a small model on your laptop.
If the tasks you’re trying to do with these models involve working with data you provide, they’ll do great. If you are asking them to provide the data, they’ll do very poorly.
