OpenAI's New Open gpt-oss Models vs o4-mini: A Real-World Comparison

What this post added

This post introduces and evaluates the gpt-oss-120B model on the Together AI platform. It details a comparative analysis against o4-mini across five practical tests: terminal snake game development, creative SVG generation, advanced instruction following, mathematical reasoning, and web-enhanced information synthesis. The results show gpt-oss-120B outperforming o4-mini in code generation and instruction following, tying in mathematical reasoning and web synthesis, and showing mixed results in creative SVG generation. The post also emphasizes the benefits of open-source models, including customization, cost-efficiency, and deployment flexibility, and highlights Together AI's optimized inference speeds and competitive pricing for these models.
