🔥Introducing ARM-Thinker, the first Agentic multimodal Reward Model that autonomously invokes external tools to ground judgments in verifiable evidence. Accepted to CVPR 2026! 🥳Integrates three families of multimodal tools: 1⃣Image Crop & Zoom-in for fine-grained visual inspection. 2⃣Document Retrieval for multi-page evidence gathering. 3⃣Instruction-Following Validators for constraint verification. 🥳With a Think-Act-Verify loop, ARM-Thinker can call image crop & zoom-in, document retrieval, and instruction-following validators for evidence-based evaluation. 🥳Built on Qwen2.5-VL-7B with SFT + two-stage GRPO, ARM-Thinker improves multimodal reward modeling, tool-use reasoning, and multimodal math/logical reasoning. 😉+16.2% on reward modeling benchmarks (outperforming GPT-4o). 😉+9.6% on tool-use / think-with-images tasks (matching Mini-o3). 😉+4.2% on multimodal math & logical reasoning. 🥳Also introduce ARMBench-VL, the first multimodal reward benchmark that requires tool use. 📄 Paper: arxiv.org/abs/2512.05111 💻 Code: github.com/InternLM/ARM-T… 🤗 Dataset: @huggingface huggingface.co/datasets/inter… 🧪 Evaluation: github.com/open-compass/V…

🚀Meet InternVL-U: a lightweight 4B unified multimodal model that brings reasoning, generation, and editing into a unified framework. 🔥Built upon unified contextual modeling, modality-specific modular design, and decoupled visual representations, InternVL-U achieves a strong performance-efficiency trade-off, consistently outperforming unified baselines with over 3× larger model scales on challenging tasks such as text rendering, scientific reasoning, and spatially grounded generation and editing. 😉Open-source and designed for efficient, practical multimodal intelligence. 🤗GitHub: github.com/OpenGVLab/Inte… 🤗Hugging Face: @huggingface huggingface.co/InternVL-U/Int… 🤗GenEditEvalKit: github.com/open-compass/G… 🤗TextEdit: github.com/open-compass/T… 🤗Tech report: arxiv.org/pdf/2603.09877

🚀 Introducing Spatial-SSRL, the first study which proposes a Self-Supervised Reinforcement Learning paradigm for spatial understanding. 💡 Spatial-SSRL a lightweight tool-free framework that aims at enhancing spatial intelligence and is natually compatible with the RLVR training paradigm. Only raw 2D and RGB-D images are required and we avoid any use of human annotation, external proprietary model or expert model throughout the entire pipeline, making Spatial-SSRL highly cost-effective and scalable. 🛰️ Spatial-SSRL comprises five pretext tasks now: shuffled patch reordering, flipped patch recognition, cropped patch inpainting, regional depth ordering, and 3D relative position prediction. Thanks to its lightweight characteristics, Spatial-SSRL can be easily extended to more pretext tasks and we welcome the whole community to join Spatial-SSRL with effective pretext tasks! 🤖 After applying Spatial-SSRL, we significantly enhance the performance of spatial understanding on Qwen2.5-VL (3B&7B) and Qwen3-VL (4B), as well as retaining their general visual capabilities. 🤗 Currently, we have released the repository of Spatial-SSRL, the dataset Spatial-SSRL-81k, and the trained models: Spatial-SSRL-7B and Spatial-SSRL-Qwen3VL-4B. The total download of the models and dataset has surpassed 1,000. 👇 Try Spatial-SSRL-7B now at: huggingface.co/spaces/yuhangz… Paper: arxiv.org/abs/2510.27606 Github: github.com/InternLM/Spati… Model (on Qwen2.5-VL): huggingface.co/internlm/Spati… Model (on Qwen3-VL): huggingface.co/internlm/Spati… Dataset: huggingface.co/datasets/inter…

🚀Introducing #CapRL, the first study of applying GRPO for the open-ended and subjective image captioning task. 🤯 🤖The trained CapRL-3B model achieves image captioning performance comparable to Qwen2.5-VL-72B. ✨CapRL introduces a novel training framework that redefines caption quality through its utility: a high-quality caption should enable a non-visual language model to accurately answer questions about the corresponding image. 📈Currently, CapRL is open-sourced, with total downloads of the models and datasets surpassing 7,000. The research team is continuously iterating with stronger base models and improved training recipe. 👇 Try it now at: huggingface.co/spaces/yuhangz… Paper: arxiv.org/abs/2509.22647 GitHub: github.com/InternLM/CapRL Model: huggingface.co/internlm/CapRL… Dataset: huggingface.co/datasets/inter…
