 #### ⚡ Efficient Post-training for Reasoning
 - [InfiAlign](http://huggingface.co/collections/InfiX-ai/infialign-688600ca363ab9ef0b78f7a6): **InfiAlign** is a scalable and data-efficient post-training framework that combines supervised fine-tuning (SFT) and reinforcement learning (RL) with a high-quality data selection pipeline to enhance reasoning in large language models.
+- [InfiMMR](https://arxiv.org/abs/2505.23091): **InfiMMR** is a novel three-phase curriculum framework that systematically enhances multimodal reasoning capabilities in small language models through foundational reasoning activation, cross-modal adaptation, and multimodal reasoning enhancement. 
 
 #### 🖥️ Advanced Vision-Native GUI Agent Model
-- [InfiGUI](https://huggingface.co/papers/2501.04575): **InfiGUIAgent** is a GUI agent powered by a multimodal large language model, designed to perform multi-step task automation through native reasoning. It is trained with a two-stage supervised pipeline that combines GUI understanding with hierarchical and expectation-reflection reasoning.
-- [InfiGUI-R1-3B](https://huggingface.co/InfiX-ai/InfiGUI-R1-3B): **InfiGUI-R1** is an MLLM-based GUI agent developed through our Actor2Reasoner framework.
+- [InfiGUIAgent](https://huggingface.co/papers/2501.04575): **InfiGUIAgent** is a GUI agent that embeds native hierarchical and expectation-reflection reasoning through a unique two-stage supervised pipeline, enabling robust, multi-step GUI task automation. 
+- [InfiGUI-R1](https://huggingface.co/InfiX-ai/InfiGUI-R1-3B): **InfiGUI-R1** is a GUI agent developed via the Actor2Reasoner framework, which evolves a reactive model into a deliberative reasoner capable of sophisticated planning and error recovery through spatial reasoning distillation and reinforcement learning.
 
 #### 🔗 Model over Models
 - [InfiFusion](https://huggingface.co/collections/InfiX-ai/infifusion-683c7d7f00c71614ba8ceb96): **InfiFusion** is a logit-level fusion pipeline based on Universal Logit Distillation, enhanced with Top-K filtering and logits standardization. It supports both pairwise and unified fusion strategies to balance performance and efficiency.
