The difference between reasoning models and normal models is reasoning models are two steps, to oversimplify it a little they prompt “how would you go about responding to this” then prompt “write the response”

It’s still predicting the most likely thing to come next, but the difference is that it gives the chance for the model to write the most likely instructions to follow for the task, then the most likely result of following the instructions - both of which are much more conformant to patterns than a single jump from prompt to response.

The difference is people still write Java, regardless of whether it’s a dated pos or not, so the use cases have evolved

Then there’s the use of the JVM/JRE which have evolved even more due to Scala, Clojure & Kotlin
