+# GPT-2.5-Math
+
+GPT-2.5-Math is an upgraded version of **BikoRiko/GPT-2.4-High-Pro**, featuring an expanded architecture and specialized fine-tuning on mathematical reasoning.
+
+## Model Details
+- **Architecture:** GPT-2 with 6 additional layers (Total parameters ~0.2B).
+- **Training Hardware:** NVIDIA H100 (via Modal.com).
+- **Dataset:** 5% subset of `microsoft/orca-math-word-problems-200k`.
+- **Objective:** Fine-tuned to solve math word problems and logical queries.
+
+## Performance
+The model is trained for mathematical reasoning. While it is a 0.2B parameter model, it demonstrates the beginning of logical grounding for basic word problems.
+
+## Training Details
+- **Optimizer:** AdamW
+- **Precision:** Mixed Precision (torch.amp)
+- **Epochs:** 3
+- **Learning Rate:** 5e-5
