gpt-oss is out! we made an open model that performs at the level of o4-mini and runs on a high-end laptop (WTF!!) (and a smaller one that runs on a phone). super proud of the team; big triumph of technology.

@SametOymac @peter_richtarik All the papers in my AC batch are <= 3.5. It probably depends a lot on the topic area 🙂
Some SAC context for NeurIPS review scores - out of my batch of 100 papers: - 1 paper ≥5.0 - 6 papers ≥4.5 - 11 papers ≥4.0 - 25 papers ≥3.75 - 42 papers ≥3.5 So currently naive accept cutoff would be 3.75.
