Marin 535B-A23B is 13% through training. This hero run would not be possible without the generous support of the Jen-Hsun and Lori Huang Foundation, which provided the funding for the compute (Coreweave). Thanks @JensenHuang for supporting open models! https://t.co/1qBdgV79S8

The "What-If Machine" is a vivid articulation of what Simile is building. It's not just about forecasting the future passively. It's about understanding how active interventions on the world change its course. It's the classic difference between causation and correlation.

Marin 535B-A23B is ~7% done training, and so far things look on track. Next Tuesday (Sept 1 @ 10 PT), we will have a Zoom panel/discussion where the Marin team will talk about the design decisions that went into this run, the tradeoffs made, and our learnings. If you're https://

The fact that Simile’s first technical blog post is about confidence is notable. Confidence is paramount to simulation. If a coding agent messes up, you can often tell and repair. If a simulation is wrong, you might never know and make a bad consequential decision based on it.

In addition to forecasting our final loss, we can also forecast the loss of intermediate checkpoints, so we can see if we’re on track over the voyage: https://t.co/CivuJfdPtT

@percyliang looks really great! one question - is anyone fulltime on Marin (aka, it's their fulltime job), or is it made up of people volunteering time?

What would truly open-source AI look like? Not just open weights, open code/data, but *open development*, where the entire research and development process is public *and* anyone can contribute. We built Marin, an open lab, to fulfill this vision: https://t.co/racsvmhyA3

Marin (https://t.co/Kn8ynNMz7u) repurposes GitHub, which has been successful for open-source *software*, for AI:
1. Preregister an experiment as a GitHub issue
2. Submit a PR, which implements the experiment in code
3. PR is reviewed by experts in the community
4. Watch the https
