+# 🧠 Manthan-M1
+
+> *"Manthan" means churning — the churning of ideas to produce clarity, depth, and structured reasoning.*
+
+**Manthan-M1** is a ~24–25B parameter multimodal reasoning model built in India for high-performance STEM, competitive exam solving, and multilingual understanding.  
+It combines a Vision-Language encoder with a fine-tuned reasoning LLM and is optimized for structured, tool-augmented problem solving.
+
+Built independently with a focus on Indian academic excellence 🇮🇳
+
+---
+
+## 🚀 Overview
+
+- **Model Size:** ~24–25B parameters  
+- **Architecture:** Two-stage unified multimodal reasoning pipeline  
+- **Quantization:** MXFP4 (LLM), BF16 (VLM)  
+- **Repository Size:** ~20GB  
+- **Primary Focus:**  
+  - JEE (Mains & Advanced)  
+  - AIME / IMO-level reasoning  
+  - STEM benchmarks  
+  - Multilingual Indian language support  
+  - Tool-augmented mathematical reasoning  
+
+---
+
+## 🏗 Architecture
+
+Manthan-M1 is a **two-stage reasoning system wrapped as a single model interface**:
+
+### 1️⃣ Vision Module
+- Based on **Qwen-3-VL encoder**
+- Converts image → dense embeddings
+- Handles:
+  - Diagrams
+  - Geometry figures
+  - OCR-heavy exam sheets
+  - Charts and tables
+
+### 2️⃣ Reasoning Module
+- Based on **openai/gpt-oss-20b**
+- Heavily fine-tuned on:
+  - 30 years of competitive math exams
+  - Olympiad-style problems
+  - Indian entrance examinations
+  - Structured reasoning datasets
+- Optimized for tool usage and step-based reasoning
+
+> Designed to outperform larger open-weight baselines in math-heavy benchmarks.
