#### 🚀 引言 | Introduction
在當前 LLM 的軍備競賽中，大家都在討論「推理能力」。但你是否好奇，為什麼某些模型（如 Claude）在處理複雜邏輯時展現出異常的深度？答案可能不在於「堆疊更多層數」，而是在於「如何重複利用層數」。
*In the current LLM arms race, everyone is discussing "reasoning capabilities." But have you ever wondered why certain models, such as Claude, exhibit extraordinary depth when handling complex logic? The answer may not lie in "stacking more layers," but in "how layers are reused."*
**OpenMythos** 是一個令人興奮的開源專案，它試圖從第一原理出發，基於公開研究文獻，理論性地重建 Claude 傳聞中的 **Mythos 架構**。它挑戰了傳統 Transformer 的線性結構，引入了「遞迴深度」的概念。
***OpenMythos** is an exciting open-source project that attempts to theoretically reconstruct the rumored **Mythos architecture** of Claude, built from first principles based on publicly available research. It challenges the linear structure of traditional Transformers by introducing the concept of "Recurrent Depth."*

#### 🛠️ 核心功能解析 | Key Features
OpenMythos 並非簡單的權重堆疊，而是一個精密的遞迴系統。其架構分為三個關鍵階段：
*OpenMythos is not a simple stack of weights, but a sophisticated recurrent system. Its architecture is divided into three key stages:*
1. **序曲 (Prelude):** 標準的 Transformer 區塊，用於對輸入進行初步編碼。
* **Prelude:** Standard transformer blocks used for initial encoding of the input.*
2. **遞迴區塊 (Recurrent Block):** 這是核心所在。模型會將隱藏狀態在同一組權重中循環運算多次（由 `max_loop_iters` 定義）。
* **Recurrent Block:** This is the core. The model cycles the hidden state through the same set of weights multiple times (defined by `max_loop_iters`).*
3. **尾聲 (Coda):** 最後的標準層，將遞迴處理後的深度特徵轉換為最終輸出。
* **Coda:** Final standard layers that transform the depth-processed features into the ultimate output.*
此外，它還提供了靈活的注意力機制選擇（**MLA** 或 **GQA**）以及基於 **MoE (Mixture of Experts)** 的前饋網路，使其能夠在計算資源與推理深度之間取得平衡。
*Additionally, it offers flexible attention mechanism choices (**MLA** or **GQA**) and a feed-forward network based on **MoE (Mixture of Experts)**, allowing it to balance compute resources with reasoning depth.*

#### 💡 技術亮點與創新 | Why It Matters?
**為什麼「遞迴」比「堆疊」更強大？**
*Why is "Recurrence" more powerful than "Stacking"?*
傳統 Transformer 是「一次性」通過所有層級。而 OpenMythos 實現的 **遞迴深度 Transformer (RDT)** 允許模型在單次前向傳播中，於潛在空間（Latent Space）內進行「靜默思考」。
*Traditional Transformers pass through all layers "once." The **Recurrent-Depth Transformer (RDT)** implemented in OpenMythos allows the model to engage in "silent thinking" within the latent space during a single forward pass.*
這意味著：**相同的參數量 $\rightarrow$ 更多的運算循環 $\rightarrow$ 更深的邏輯推理。**
*This means: **Same parameter count $\rightarrow$ More computation loops $\rightarrow$ Deeper logical reasoning.***
這種機制能有效解決「系統化泛化」問題。模型不再僅僅是模式匹配，而是在遞迴過程中不斷精煉答案，這解釋了為什麼某些頂級模型在不需要輸出「思維鏈 (CoT)」的情況下依然能展現出強大的邏輯能力。
*This mechanism effectively addresses "systematic generalization." The model no longer just performs pattern matching but refines the answer through recurrence, explaining why some top-tier models exhibit strong logical capabilities without needing to output an explicit "Chain-of-Thought (CoT)."*

#### 📦 快速上手 | Quick Start Guidance
OpenMythos 提供了極其簡潔的安裝與調用方式，讓研究人員能快速驗證遞迴深度對結果的影響。
*OpenMythos provides a concise installation and invocation process, allowing researchers to quickly verify the impact of recurrent depth on results.*
**1. 安裝 (Installation):**
```bash
pip install open-mythos
```
**2. 核心實作邏輯 (Core Implementation):**
你可以透過設定 `n_loops` 來控制模型「思考」的深度。
*You can control the depth of the model's "thinking" by setting `n_loops`.*
```python
from open_mythos.main import OpenMythos, MythosConfig
# 配置 MLA 注意力與遞迴參數
cfg = MythosConfig(
vocab_size=1000, dim=256, n_heads=8,
max_loop_iters=4, attn_type="mla", # 關鍵：定義最大循環次數
# ... other params
)
model = OpenMythos(cfg)
# 執行 4 次遞迴循環進行推理
logits = model(ids, n_loops=4)
```

#### 🔗 專案資源與連結 | Conclusion & Links
OpenMythos 不僅僅是一個程式碼庫，它更像是一場關於 LLM 未來演進的科學實驗。它告訴我們，AI 的進化方向可能不在於模型變得更大，而是在於運算過程變得更「深」。
*OpenMythos is more than just a codebase; it is a scientific experiment on the future evolution of LLMs. It suggests that the evolution of AI may not be about models becoming larger, but about the computation process becoming "deeper."*
如果你對 Transformer 的底層架構、遞迴神經網絡或 Claude 的設計哲學感興趣，這個專案絕對不容錯過。
*If you are interested in the underlying architecture of Transformers, Recurrent Neural Networks, or the design philosophy of Claude, this project is an absolute must-see.*
