Speculation suggests OpenAI o1 uses GLM architecture, rivaling Claude
teortaxesTex · x · 2026-08-21
Based on experience with DSH projects, the author speculates that OpenAI's o1 (ox alpha) is likely built on a GLM architecture, possibly an enhanced 5.x version with vision capabilities rather than a massive 1T parameter model. The assessment describes it as tighter, stronger, and more professional, with performance capable of trading blows with Anthropic's Sol model.
