-    if b == 0:
-        return a
-    else:

-The base model loops into repetitive, non-answering text. The fine-tuned model
-reliably switches into clean, structured Python — the LoRA clearly taught the
-`### Assistant:` turn to produce code instead of chatter.
+The base model drifts into a generic essay outline and never writes any code. The
+fine-tuned model answers directly with a correct, runnable Python function — the LoRA
+clearly taught the `### Assistant:` turn to produce code instead of chatter.
 
 ## Limitations
 
-This is a small run (500 iterations, rank 8). Formatting and "answer with code"
-behavior improved a lot, but generalization is imperfect — in the example above the
-fine-tuned model actually emits a *division* function with a zero-check, not a sum,
-for an "add two numbers" prompt. Treat outputs as a draft to review, not
-production-ready code.
