InternLM Releases Intern-S2-397B: Multimodal Model for Scientific AI and Long-Horizon Agents
jacek2023 · reddit · 2026-09-13
InternLM introduced Intern-S2-397B, its most capable multimodal foundation model for scientific intelligence and long-horizon agents, scaling along pre-training, RL task coverage, and interactive agent environments.
- New pre-training paradigm: visual pretraining directly on raw pages of scientific literature, jointly modeling symbolic semantics and visual relationships without intermediate parsing.
- Scientific reasoning & generation: RL tasks scaled across 20+ scientific domains yield leading open-source general reasoning and strong results in biomolecular interaction design and material structure generation.
- Long-horizon agents: multiple agent frameworks connected to large-scale sandboxed environments for black-box agentic RL, raising the ceiling on long-horizon tasks.
