+# ⚛️ Atomight-2-1.5B-Thinking
+
+**A Deep-Reasoning Small Language Model Optimized for Sequential Logic Chains**
+
+</div>
+
+## 📌 Model Overview
+**Atomight-2-1.5B-Thinking** is a specialized, compact reasoning model built on top of a 1.5B parameter core architecture. Engineered explicitly for users operating on constrained hardware environments (such as a free Google Colab T4 instance), Atomight-2 utilizes an explicit internal `<think>...</think>` scratchpad layout. It dynamically breaks down complex mathematical, logical, and structural prompts before committing to a final conclusion.
+
+### 🚀 Key Highlights
+* **Hardware Democratic:** High-tier deep reasoning accessible on consumer-grade hardware and free cloud compute tiers.
+* **Structured Scratchpad:** Generates native, visible reasoning pathways natively formatted for transparent auditing.
+* **Chat-Template Native:** Tailored directly for ChatML system configurations.

+## 📊 Evaluation & Benchmark Results
+
+Atomight-2 was subjected to a high-volume statistical evaluation matrix across core logic paradigms, matching up against premier industry baselines in the 1B–4B small language model class. 
+
+### Official Performance Breakdown
+The model displays exceptional specialization spikes in structured mathematical deduction, rivaling or outperforming significantly larger parameters classes on core numerical strings.

+
+> ⚠️ **Evaluation Insight:** While Atomight-2 exhibits class-leading spikes on core textual logic and mathematical proofs, it experiences a classic reasoning tradeoff. On abstract matrix-grid visual transformation evaluations (like ARC-AGI 2), it drops to a baseline floor of **0.00%**. This cognitive bottleneck highlights an instruction deficit in translating spatial imagery into basic structural text tokens—a major priority slated for the next architecture generation.

+## 💻 Quickstart & Inference Code
+
+To deploy Atomight-2 cleanly without encountering text-truncation errors inside the internal reasoning blocks, execute the generation using the official structured chat template format.
+
+```python
+import torch
+from transformers import AutoTokenizer, AutoModelForCausalLM
+
+MODEL_ID = "NovatasticRoScript/Atomight-2-1.5B-Thinking"
+
+tokenizer = AutoTokenizer.from_pretrained(MODEL_ID, trust_remote_code=True)
+model = AutoModelForCausalLM.from_pretrained(
+    MODEL_ID, 
+    torch_dtype=torch.float16, 
+    device_map="auto",
+    trust_remote_code=True
+)
+
+# Structure conversational dialog into ChatML framework
+messages = [
+    {"role": "user", "content": "A retailer buys shirts for $15 and sells them for $25. What is the total profit on 12 shirts?"}
+]
+
+templated_input = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
+inputs = tokenizer(templated_input, return_tensors="pt").to("cuda")
+
+print("🧠 Generating Reasoning Sequence:")
+outputs = model.generate(
+    **inputs, 
+    max_new_tokens=768, # Plentiful headroom required for deep-thinking scratchpads
+    temperature=0.1,
+    do_sample=False,
+    pad_token_id=tokenizer.eos_token_id
+)
+
+print(tokenizer.decode(outputs[0], skip_special_tokens=False))
