+This model is a safety-aligned version of [Llama-3-8B-DPO](https://huggingface.co/Nagi-ovo/Llama-3-8B-DPO) using PPO (Proximal Policy Optimization) methodology. The model aims to better align with human preferences while maintaining the base model's capabilities [1](https://github.com/OpenRLHF/OpenRLHF).
 ## Training Details
+### Base Model and Architecture
+- Base Model: DPO-tuned Llama-3-8B
+- Alignment Method: PPO with implementation tricks for improved training stability
+- Model Components: Separate Actor, Critic, and Reward models with shared reference model
+### Training Configuration
+- Dataset: PKU-SafeRLHF-30K for human preference alignment
+- Training Duration: 1 epoch
+- Batch Size: 128
+- Learning Rate:
+  - Actor: 1e-5
+  - Critic: 1e-5

+### Optimization and Infrastructure
+- Memory Optimization:
+  - **QLoRA** training for efficient parameter updates
+  - **LoRA adapters** for Actor/Critic/Reward models mounted on reference model
+  - Flash Attention 2 for improved memory efficiency
+- Training Infrastructure:
+  - Hardware: 4 x RTX 4090 (48GB VRAM version)
+  - Framework: DeepSpeed Stage 1 with ZeRO optimization
+## Training Statistics

+### RuoZhiBa QA
+```css
+Input: 为啥长寿的碰巧都是老年人？
+Output: 由于长寿的定义是指一个人活得很长时间，通常意味着他或她已经过了中年。因此，长寿的人通常都是老年人。
+```
+```css
+Input: 赤道那么暖和，为什么不给我们北方修一条？
+Output: 由于赤道附近的温度较高，北方的温度较低，因此不可能在北方修一条赤道。

+### Coding
+```css
+Input: give me a C++ code about quick sort.
+Output: Here is a simple implementation of quick sort in C++:
+```c++
+#include <iostream>
+#include <vector>
+#include <algorithm>
+void quickSort(std::vector<int>& arr, int left, int right) {
+    if (left >= right) return;

+    int i = left, j = right;
+    while (i < j) {
+        while (arr[i] < pivot) i++;
+        while (arr[j] > pivot) j--;
+        if (i < j) {
+            std::swap(arr[i], arr[j]);
+            i++;
+            j--;
+        }
+    }
+    quickSort(arr, left, j);
+    quickSort(arr, j + 1, right);
+}
+int main() {
+    std::vector<int> arr = { 5, 4, 3, 2, 1 };
+    quickSort(arr, 0, arr.size() - 1);
