1. Tutorial Introduction

gpt-oss-20b is an open-source inference model launched by OpenAI in August 2025. It targets strong reasoning, agent-based tasks, and diverse development scenarios. Based on the MoE architecture, this model supports a context length of 128k and offers performance comparable to the closed-source o4-mini and o3-mini models. It excels in tool invocation, few-shot function calls, chained reasoning, and health question-answering.
