要旨
私たちは、初の1兆パラメータ規模を持つ科学マルチモーダル基盤モデル「Intern-S1-Pro」を紹介します。この前例のない規模へのスケーリングにより、モデルは一般領域と科学領域の両方で包括的な性能向上を実現しています。強力な推論能力と画像-テキスト理解能力に加え、高度なエージェント機能によってその知能はさらに拡張されています。同時に、化学、材料、生命科学、地球科学などの重要科学分野にわたる100以上の専門タスクを習得するなど、科学的専門性が大幅に拡充されました。この大規模化は、XTunerとLMDeployによる堅牢なインフラ支援によって可能となり、1兆パラメータレベルでの高効率な強化学習（RL）訓練を実現するとともに、訓練と推論間の厳密な精度一貫性を保証しています。これらの進歩をシームレスに統合することで、Intern-S1-Proは「特殊化可能なジェネラリスト」として一般知能と専門知能の融合をさらに強化し、一般能力においてオープンソースモデルの最高水準に位置づけられる一方、専門的な科学タスクの深さにおいてはプロプライエタリモデルを凌駕する性能を示しています。

We introduce Intern-S1-Pro, the first one-trillion-parameter scientific multimodal foundation model. Scaling to this unprecedented size, the model delivers a comprehensive enhancement across both general and scientific domains. Beyond stronger reasoning and image-text understanding capabilities, its intelligence is augmented with advanced agent capabilities. Simultaneously, its scientific expertise has been vastly expanded to master over 100 specialized tasks across critical science fields, including chemistry, materials, life sciences, and earth sciences. Achieving this massive scale is made possible by the robust infrastructure support of XTuner and LMDeploy, which facilitates highly efficient Reinforcement Learning (RL) training at the 1-trillion parameter level while ensuring strict precision consistency between training and inference. By seamlessly integrating these advancements, Intern-S1-Pro further fortifies the fusion of general and specialized intelligence, working as a Specializable Generalist, demonstrating its position in the top tier of open-source models for general capabilities, while outperforming proprietary models in the depth of specialized scientific tasks.
