Intern S2 Preview 397B
Intern S2 Preview scales multimodal pretraining, scientific reinforcement learning, and long-horizon agent environments. It learns from raw pages of scientific literature and combines general reasoning with tasks across more than twenty scientific domains. The 397B checkpoint supports language output, image understanding, and tool calls. Its text evaluations use up to 256K inference, while multimodal evaluations use shorter 64K limits. The official laboratory announcement identifies the public release date as 2026-07-17.
