                    - _Complete_ vs _Instruct_:
                        - <u>Complete</u>: Code Completion based on the (verbose) structured docstring. This variant tests if the models are good at coding.
                        - <u>Instruct</u> (🔥Vibe Check🔥): Code Generation based on the (less verbose) NL-oriented instructions. This variant tests if the models are really capable enough to understand human intents to code.
                    - `complete` and `instruct` represent the calibrated Pass@1 score on the BigCodeBench benchmark variants.
                    - `elo_mle` represents the task-level Bootstrap of Maximum Likelihood Elo rating on `BigCodeBench-Complete`, which starts from 1000 and is boostrapped 500 times.
                    - `size` is the amount of activated model weight during inference.
                    - Model providers have the responsibility to avoid data contamination. Models trained on close data can be affected by contamination.
