OpenAI’s refusal to back open weights reignites the open-vs-closed divide

PsychicorAI · reddit · 2026-07-25

A Reddit post argues that OpenAI refusing to sign a letter supporting open-weight models shows a mission drift away from its original “open” positioning.

The attached image frames the dispute as a broader industry split: many companies and leaders are publicly backing open weights, while OpenAI and Anthropic are singled out as the two major frontier players not on the letter.

The post is opinionated rather than evidentiary, but the underlying news value is the growing visibility of the open-weight vs. closed-model divide.
