# Why Your LLM Bill Doubled Reasoning models like o1 and o3 process queries through extended chains of thought before responding, consuming 5-10x more tokens internally than standard models while also charging higher per-token rates. This means both your input token usage and per-unit costs increased simultaneously—a compounding effect that easily doubles overall spend. Unless you've significantly reduced queries to other models or have very selective reasoning deployment, the math makes a doubling entirely predictable.

# Fixed Function ```python def longest_run(xs): if not xs: return 0 best = 1 cur = 1 for i in range(1, len(xs)): if xs[i] == xs[i - 1]: cur += 1 best = max(best, cur) else: cur = 1 return best ``` # Bug Explanation The original function has two related bugs stemming from incorrect initialization and loop logic. First, `best` and `cur` start at 0, which causes single-element lists to incorrectly return 0 instead of 1—a run of one identical element should have length 1. Second, `cur` is reset to 0 (not 1) when a mismatch occurs, causing the next matching pair to be undercounted. More critically, if the longest run ends at the last index, `best` is only updated *during* the loop when a mismatch is encountered; if no mismatch follows the final run, `best` never captures it.
