+# Model Card for Chemistry-R1
+
+ 
+## Model Details
+
+- **Name:** Chemistry-R1
+- **Base Model:** Qwen3-0.6B
+- **Fine-Tuning Dataset:** ~2,000 chemistry reasoning problems, where solutions are computed step-by-step using Python code.
+- **Training Objective:** The model was fine-tuned to reason through chemistry problems, generate step-by-step solutions using Python, and compute the final answer programmatically.
+
+- Capabilities:
+  - Solves quantitative chemistry problems using code-based reasoning.
+  - Generates intermediate steps to explain calculations and chemical logic.
+  - Can output results as numerical answers, chemical equations, or calculated values.
+
+## Uses
+
+### Direct Use
+
+This model is designed for:
+- Educational Assistance: Helping students and educators solve and explain chemistry problems programmatically.
+- Chemistry Problem Solving: Generating step-by-step solutions for quantitative chemistry calculations.
+- Automated Reasoning Pipelines: Integrating into applications where chemistry computations need algorithmic precision.
+
+
+## Bias, Risks, and Limitations
+
+- Numerical Precision: The model may occasionally produce incorrect numerical results due to floating-point approximations or coding logic errors. Always verify critical calculations.
+- Scope of Chemistry Knowledge: Fine-tuned on ~2K problems, so it may fail on very advanced or niche chemistry topics not represented in the training set.
+- Python Execution Needed: The model generates Python code to solve problems, so it relies on a safe execution environment for computing final answers. It may not directly provide plain-text solutions without executing code.
+- No Safety Checks: It does not account for chemical hazards, experimental safety, or lab protocols—only theoretical reasoning.
+- Limited Generalization: Performance may degrade on problems requiring multi-step reasoning beyond the patterns seen in the fine-tuning dataset.
