Sam Witteveen explains who Ricursive is and what makes its Ripple-65B Preview open model different.
What is it?
'Ripple 65B: A Chip Design Lab Just Beat Every US Open Model' went up on Sam Witteveen's channel on 5 November 2026. The 20-minute video covers Ripple-65B Preview, the open-weight model released by Ricursive, a company that builds AI models for chip design rather than general LLMs.
How does it work?
Chapters move from who Ricursive is and what it released to the Apache 2.0 license and a comparison with Chinese open models. Witteveen then looks at how the lab says it built the model for $32M, its thin and deep architecture, and a short demo.
Why does it matter?
Ripple-65B Preview is pitched as the strongest US open-weight model for agentic coding, and the video helps viewers judge that claim before trying the Hugging Face weights.
