# Benchmark summary
We introduce HumanEval for Kotlin, created from scratch by human experts.
Solutions and tests for all 161 HumanEval tasks are written by an expert olympiad programmer with 6 years of experience in Kotlin, and independently checked by a programmer with 4 years of experience in Kotlin.
The tests we implement are equivalent to the original HumanEval tests for Python.
# How to use
The benchmark is prepared in a format suitable for MXEval and can be easily integrated into the MXEval pipeline.
When testing models on this benchmark, during the code generation step we use early stopping on the `}\n}` sequence to expedite the process. We also perform some code post-processing before evaluation — specifically, we remove all comments and signatures.
The code for running an example model on the benchmark using the early stopping and post-processing is available below.
```python
import json
import re
from datasets import load_dataset
import jsonlines
import torch
from transformers import (
AutoTokenizer,
AutoModelForCausalLM,
StoppingCriteria,
StoppingCriteriaList,

) -> bool:
last_three_tokens = [int(x) for x in input_ids.data[0][-3:]]
decoded_last_three_tokens = self.tokenizer.decode(last_three_tokens)
return bool(re.search(self.stops, decoded_last_three_tokens))
