+# MOSS-VL-Base-0708
+
+## Introduction
+
+MOSS-VL-Base-0708 is the foundation checkpoint of the MOSS-VL 0708 release, part of the OpenMOSS ecosystem for open visual understanding.
+
+Built through multimodal pretraining only, this checkpoint serves as a high-capacity offline multimodal base model. It provides strong general-purpose visual-language representations across image and video inputs, and is intended primarily as the base model for supervised fine-tuning, alignment, and domain adaptation.
+
+The 0708 release keeps the MOSS-VL cross-attention design and a 256K text context window while refreshing the data and pretraining recipe for stronger offline multimodal foundations.
+
+Specifically, the pretraining pipeline follows four progressive stages:
+
+- Stage 1: Vision-language alignment
+- Stage 2: Large-scale multimodal pretraining
+- Stage 3: High-quality multimodal pretraining
+- Stage 4: Annealing and long-context extension
+
+## Highlights
+
+- Strong foundation model: provides general visual-language representations for image, video, and text inputs.
+- Native dynamic resolution: processes images and video frames at their original aspect ratios and resolutions.
+- Native interleaved image and video inputs: supports mixed image/video/text sequences in a unified pipeline.
+- Open base checkpoint: designed for continued pretraining, supervised fine-tuning, alignment, and domain adaptation.
+
+## Model Architecture
+
+MOSS-VL-Base-0708 adopts a cross-attention-based vision-language architecture that decouples visual encoding from language reasoning. The model processes images, videos, and text in a unified pipeline and uses cross-attention layers to connect language tokens with visual representations.

+
+Key configuration details:
+
+| Item | Value |
+| --- | --- |
+| Parameters | 11B |
+| Tensor type | BF16 |
+| Context length | 256K |
+| Vision patch size | 16 |
+| Temporal patch size | 1 |
+| Default video FPS | 1.0 |
+| Default max video frames | 256 |
+
+## Absolute Timestamps
+
+For video inputs, MOSS-VL injects absolute timestamps alongside sampled frames. This helps the base model learn event order, duration, pacing, and temporal localization instead of relying only on frame order.
+
+## Cross-attention RoPE (XRoPE)
+
+MOSS-VL uses Cross-attention Rotary Position Embedding (XRoPE), which maps text tokens and visual patches into a unified three-dimensional coordinate space defined by Time (t), Height (h), and Width (w). This gives the model a consistent positional representation for image and video understanding.
+
+## Model Performance
+
+MOSS-VL-Base-0708 is intended as a pretrained foundation checkpoint for offline multimodal understanding and model adaptation. Detailed benchmark tables for the 0708 release will be maintained in the MOSS-VL project resources.

+## Limitations and Future Work
+
+MOSS-VL-Base-0708 is a pretrained base checkpoint. It is not instruction-tuned, so applied use cases should generally fine-tune or align it before using it as an assistant-style model.
+
+We are continuing to improve OCR and document understanding, extremely long video understanding, mathematical reasoning, code reasoning, RL post-training, and broader task-specific evaluations for future MOSS-VL releases.
