  • I don’t agree that ChatGPT has gotten dumber, but I do think I’ve noticed small differences in how it’s engineered.

    I’ve experimented with writing apps that use the OpenAI api to use the GPT model, and this is the biggest non-obvious problem you have to deal with that can cause it to seem significantly smarter or dumber.

    The version of GPT 3.5 and 4 used in ChatGPT can only “remember” 4096 tokens at once. That’s a total of its output, the user’s input, and “system messages,” which are messages the software sends to give GPT the necessary context to understand. The standard one is “You are ChatGPT, a large language model developed by OpenAI. Knowledge Cutoff: 2021-09. Current date: YYYY-MM-DD.” It receives an even longer one on the iOS app. If you enable the new Custom Instructions feature, those also take up the token limit.

    It needs token space to remember your conversation, or else it gets a goldfish memory problem. But if you program it to waste too much token space remembering stuff you told it before, then it has fewer tokens to dedicate to generating each new response, so they have to be shorter, less detailed, and it can’t spend as much energy making sure they’re logically correct.

    The model itself is definitely getting smarter as time goes on, but I think we’ve seen them experiment with different ways of engineering around the token limits when employing GPT in ChatGPT. That’s the difference people are noticing.






  • They can’t execute. Here’s my theory: their overarching plan is to create an environment where users have to see ads (like YouTube) so that they can create a revenue model to pay creators. They’re just so bad at messaging and company-wide planning that they’re doing all these things piecemeal rather than presenting it as a whole package. If they presented this all at once with one as the cost of the other, it would’ve been a little more coherent. But Reddit sucks at this and turned it into a dumpster fire. They aren’t ready to turn all the old features off at one moment and the new ones on the next.
