+## Overview
+
+**LOGOS** (**L**anguage **O**f **G**enerative **O**bjects in **S**cience) is the first multi-domain generative framework built on a unified *scientific grammar*. It encodes diverse scientific objects — proteins, antibodies, small molecules, chemical reactions, materials, and their spatial interactions — as token sequences over a shared vocabulary, enabling a single autoregressive model to perform generation, prediction, and design across the natural sciences.
+
+Unlike approaches that rely on natural language as an intermediary or require explicit 3D geometric networks, LOGOS operates directly on domain-native representations. Key spatial relationships (e.g., protein pocket–ligand contacts) are discretized and tokenized into the shared grammar, allowing the model to learn complex structural interactions in a purely sequential manner.

+
+### Key Features
+
+* **Unified Scientific Grammar**: A shared representational interface that encodes heterogeneous scientific objects and cross-object relationships into a common discrete token space.
+* **One Model Fits All**: A single autoregressive model handles tasks across proteins, small molecules, materials, reactions, antibodies, and their interactions.
+* **No Explicit 3D Geometry Required**: Spatial contact and constraint patterns are captured through tokenized representations, without relying on geometric neural networks or explicit coordinates.
+* **Pre-training & Downstream Alignment**: The grammar space ensures formal consistency between continued pre-training objectives and downstream task goals.

+
+## Supported Tasks
+
+LOGOS achieves competitive or state-of-the-art performance across six representative downstream tasks:
+
+| Task | Domain | Description |
+| ---- | ------ | ----------- |
+| Interaction-Aware Ligand Design for Binding Pockets | Drug Discovery | Generate ligands capable of specifically binding to a protein binding pocket |
+| Protein Ligand-Binding Site Identification | Structural Biology | Identify binding pockets from protein sequences |
+| Retrosynthesis Prediction | Chemistry | Predict reactants given a target product |
+| Unconditional Material Generation | Materials Science | Generate novel and valid materials |
+| Protein Editing | Protein Engineering | Edit protein sequences for improved functional properties |
+| Antibody CDR Design | Immunology | Design complementarity-determining regions for antibody engineering |

+
+## Model Architecture
+
+LOGOS is based on an autoregressive Transformer architecture with continued multi-domain pre-training on a unified scientific grammar. The framework spans a parameter range from **1B to 8B**, with stable scaling behavior observed across this range.
+
+## Quick Start
+
+```python
+from transformers import AutoModelForCausalLM, AutoTokenizer
+
+model = AutoModelForCausalLM.from_pretrained("LOGOS-Hub/LOGOS-8B")
+tokenizer = AutoTokenizer.from_pretrained("LOGOS-Hub/LOGOS-8B")
+
+input_text = "<your_scientific_grammar_input>"
+inputs = tokenizer(input_text, return_tensors="pt")
+outputs = model.generate(**inputs, max_new_tokens=512)
+print(tokenizer.decode(outputs[0], skip_special_tokens=True))
+```
