What Are 'Open' AI Models?
Computerworld, Wednesday, August 26th, 2026
Computerworld explains why enterprises are shifting from costly frontier models to open-weight ones.
Computerworld explains growing enterprise interest in open and open-weight AI models over costly proprietary systems, quoting Gartner's Deepak Seth that a general-purpose closed model trained on the whole internet is overkill for most business needs.
It distinguishes open-weight models, which allow fine-tuning but withhold training data, from true open-source models meeting Open Source Initiative standards for full transparency.
Benefits cited include on-premises data control for regulated industries, workflow customization, and governance visibility, with SemiAnalysis noting open models now catch up to each generation's leading closed model in half the time, exemplified by DeepSeek's V3 and R1 releases.
