A End-to-End Coding Guide to Running OpenAI GPT-OSS Open-Weight Models with Advanced Inference Workflows

OpenAI released two open-weight reasoning models, gpt-oss-20b and gpt-oss-120b, under the Apache 2.0 license, and MarkTechPost has published a detailed coding guide for running them in Google Colab. The smaller 20B model runs on just 12 GB of VRAM and scored 98.7 percent on the AIME 2025 mathematics benchmark, making serious reasoning AI accessible to developers without enterprise GPU budgets.

This story matters because it signals a shift in how AI agents are being adopted across the industry. The research findings here could reshape how developers build agentic systems in the coming months.
