open source vs open weight

The tag 'open source vs open weight' captures a key distinction in the AI model licensing landscape, particularly relevant for enterprise IT decision-makers evaluating large language models. Recent discussions on WindowsForum highlight how AWS now offers OpenAI's 'open-weight' models on Bedrock, breaking Microsoft's previous exclusivity. This move underscores the practical difference between open source (fully public code and weights) and open weight (model weights released but not full source code or training data). For IT professionals, understanding this distinction matters when assessing deployment flexibility, licensing costs, and vendor lock-in risks. The tag covers real-world implications for cloud strategy, model portability, and competitive dynamics among major cloud providers.
