“Don’t use ‘open weight’ and ‘open source’ interchangeably”: Percona CEO on why AI terminology matters
The New Stack published an article titled "Don't use 'open weight' and 'open source' interchangeably": Percona CEO on why AI terminology matters, dated October 9, 2026. The headline attributes the position to Percona's CEO, who argues that the two terms describe different things and should not be treated as synonyms in discussions of AI models. The excerpt supplied with the story contains almost entirely CSS and layout rules from the publication's page template rather than the article body. As a result, the specific arguments, examples, and any named models or licenses the CEO cited are not present in the available text. What can be stated from the source is limited to the framing: the piece is about terminology in AI, it centers on a distinction between "open weight" and "open source," and the speaker is Percona's CEO. No benchmark figures, version numbers, or pricing details appear in the excerpt, and none should be assumed.
The source indicates developers should treat "open weight" and "open source" as distinct labels when evaluating AI models rather than assuming they mean the same thing.
