Intern-S2-Preview: Scientific Agentic Foundation Model
Shanghai AI Lab
Intern-S2-Preview is a 397B-parameter scientific foundation model combining multimodal pretraining with SFT, RL, and memory-augmented post-training, aiming to match the trillion-scale Intern-S1-Pro on core scientific reasoning tasks while adding stronger agentic capabilities.
Why it matters
Continues the trend of large labs building dedicated science-focused foundation models rather than general chat models; a 35B variant reportedly matches trillion-scale performance on scientific benchmarks.
Importance: 3/5
Notable release: large scientific foundation model from a major lab, official arXiv/HF source.
