Code-Evol-Instruct-OSS is a dataset that was generated with Code Evol-Instruct by prompting open-souce LLMs, WizardLM-13B-v1.2 and WizardCoder-34B-Python.
The underlying process is explained in the paper code-evol-instruct. This algorithm gave birth to famous open-souce code LLMs, WizardCoder-Family.
