	# Gemma-3 270M-IT "Open-Mythos" (Phase 2.8)

	This is an experimental architectural modification of the Google Gemma-3 270M-IT base model. It implements the "Open-Mythos" (PX) architecture, introducing Recursive Computational Headroom and Fluid Gaussian Cognitive Routing.

	## ⚠️ Transparency Notice
	This is not a standard fine-tune. It is a structural mod that changes how the transformer processes tokens at inference time.
	- Base Model: [google/gemma-3-270m-it](https://huggingface.co/google/gemma-3-270m-it)
	- Modifications: Runtime patching of the forward pass to allow for recursive layer execution and dynamic cognitive routing.

	## 🚀 Key Innovations

	### 1. Recursive Computational Headroom (PX)
	Unlike standard transformers that pass through each layer once, Open-Mythos allows the model to "re-read" and "think" through specific layers (L5-L12) multiple times. This effectively increases the depth of the model for complex tasks without adding new parameters.

	### 2. Fluid Gaussian Cognitive Routing
	The model dynamically analyzes the "cognitive signature" (Kurtosis) of each prompt during the prefill phase. Based on this signature, it automatically routes the task through a specific "Cognitive Envelope":
	- Math Mode: Optimized for numerical precision (L5-L11).
	- Logic Mode: Optimized for multi-step reasoning (L8-L12).
	- Creative Mode: Optimized for semantic drift and metaphor (L10-L16).
	- Synthesis Mode: Optimized for extraction and summarization (L6-L14).

	Transitions between these modes are continuous and fluid using Gaussian blending, allowing the model to self-determine its reasoning path.

	### 3. Numerical Stability (RMSNorm Fix)
	Implements a surgical fix for the Gemma-3 RMSNorm scaling (`1.0 + weight`) to prevent signal collapse during deep recursion, ensuring vocabulary integrity across high-entropy generations.

	## 💻 Usage

	To use this model, you must set `trust_remote_code=True` because it uses custom modeling code to implement the recursive logic.

	```python
	import torch
	from transformers import AutoTokenizer, AutoModelForCausalLM

	repo_id = "neuralworm/gemma-3-270m-it-p2.8"

	tokenizer = AutoTokenizer.from_pretrained(repo_id)
	model = AutoModelForCausalLM.from_pretrained(
	repo_id,
	torch_dtype=torch.bfloat16,
	device_map="auto",
	trust_remote_code=True
	)

	prompt = "Sally has 3 brothers. Each brother has 2 sisters. How many sisters does Sally have?"
	chat = [{"role": "user", "content": prompt}]
	inputs = tokenizer(tokenizer.apply_chat_template(chat, tokenize=False, add_generation_prompt=True), return_tensors="pt").to(model.device)

	outputs = model.generate(**inputs, max_new_tokens=100)
	print(tokenizer.decode(outputs[0][inputs.input_ids.shape[1]:], skip_special_tokens=True))
	```

	## 📊 Performance
	Open-Mythos (Phase 2.8) significantly improves zero-shot performance on "Logical Traps" and multi-step reasoning compared to the pure 270M baseline, while remaining multimodal-ready and regression-free for standard NLP tasks.
