Small model's Python code generation results | Generated by AI
The eval ran. BPB failed (eval dataloader expects default nanochat data path, not our codeparrot data — we already have val_bpb from training anyway: 0.372). The Python code generation results are the real story:
Python Code Gen Results (286M model, temperature=0.3):
def fibonacci(n):
if n == 0:
return 1
else:
return fibonacci(n-1) + fibonacci(n-2)
✓ Correct recursive implementation. It then generates fibonacci2, fibonacci3 as variations.
def reverse_linked_list(head):
if head == None:
return None
if head.is_empty():
return None
if head.is_linked():
return head
return reverse_linked_list(head.next)
~ Recognizes the problem, generates plausible node API (.is_empty(), .is_linked()), but the recursion is wrong (infinite on is_linked). Shape is right.
class Stack:
def __init__(self):
self._stack = []
self._stack.append(None)
def push(self, item):
self._stack.append(item)
def pop(self):
return self._stack.pop()
def peek(self):
return self._stack[-1]
def is_empty(self):
return len(self._stack) == 0
✓ Correct — full working Stack with all standard methods.
def is_palindrome(s):
if len(s) == 0:
return False
if s[0] == s[-1]:
return True
else:
return False
~ Recognizes first/last char comparison but logic is wrong (returns True immediately, no recursion). It tried is_palindrome2, is_palindrome3 variants.
import numpy as np
import pandas as pd
import matplotlib.pyplot as plt

✓ Generates plausible import chains.
Assessment: For a 286M model trained on codeparrot-clean only (no SFT), this is solid. It learned:
- Python syntax and indentation perfectly
- Class/function structure
- Docstrings and comments
- Common import patterns
- The shape of common algorithms (even when logic is off)
Limitations are what you’d expect: small model capacity means it memorizes patterns but doesn’t deeply understand algorithms. SFT would tighten this up significantly.
