It achieves :green[**state-of-the-art**] results on HumanEval with a :green[**94.4% pass@1 rate**] on GPT-4.
Listed below is an example programming problem (https://leetcode.com/problems/longest-valid-parentheses/description/) to get started with.
```python
Given a string containing just the characters '(' and ')', return the length of the longest valid (well-formed) parentheses substring
```
:red[**NOTE:**] On average a call for a HumanEval or Leetcode question will cost around 5-30 cents on GPT-4, using the default parameters. This value may change depending on problem difficulty and parameters.
