# Tessera 4
### The Frontier of Efficiency: ORPO-Distilled Reasoning

Tessera 4 is a specialized mini-model designed to prove that massive scale is not a requirement for world-class reasoning. By utilizing **ORPO (Odds Ratio Preference Optimization)** and a high-signal distillation process from **DeepSeek-R1**, Tessera 4 achieves frontier-level performance in logic and mathematics while remaining small enough to run on consumer hardware (8GB VRAM).

## 🚀 The Reasoning Breakthrough
Tessera 4 was trained with a specific focus: **Logical Accuracy over General Trivia.** 
While we purposely allowed MMLU scores to sit at 66%, the trade-off resulted in a reasoning engine that surpasses its own teacher (DeepSeek-R1) and rivals GPT-5-class thresholds on core logic benchmarks.

### 📊 Benchmark Comparison
| Benchmark | Tessera 4 | DeepSeek-R1 | Llama 3.1 400B |
| --- | --- | --- | --- |
| **GSM8K** | **95%** | 80.1% (Base) | 90%+ |
| **ARC-Challenge** | **93%** | 90-92% | 90%+ |
| **MMLU** | 66% | 75%+ | 85%+ |

*Note: Benchmarks conducted on randomized high-signal subsets to verify zero-shot reasoning capabilities.*

## 🛠️ Technical Specifications
- **Training Duration:** ~8 Hours
- **Hardware:** 1x RTX 3090
- **Methodology:** ORPO Distillation
- **Optimization:** Focused on Chain-of-Thought (CoT) path correction, eliminating the "verbose fluff" typical of larger reasoning models.

## 💻 Hardware Requirements & Format
- **Format:** Full 16 Bit, 3090
- **VRAM:** Recommended 8GB+ 
- **Compatibility:** Optimized for LM Studio, Ollama, and llama.cpp.

## 🧠 Reasoning Showcase
*All results generated at Q4_K_M quantization (4-bit).*

### 🔢 1. High-Precision Math (15 Factorial)
**Test:** Calculate 15! step-by-step.
**Result:** 1,307,674,368,000 (**100% Correct**)
> Tessera 4 demonstrates zero-shot numerical stability, maintaining digit precision across 14 layers of multiplication.

### 📐 2. Unit Conversion & Physics
**Test:** A train travels 60km in 45 minutes. Find the speed in km/h.
**Result:** 80 km/h (**Correct**)
> The model correctly identifies the need to convert minutes to hours (0.75h) before applying the distance/time formula.

### 👽 3. Deep Logical Branching (The 3 Aliens)
**Test:** A complex "Truth-Teller, Liar, Alternator" puzzle.
**Result:** Successfully identified Z=Truth, X=Alternator, Y=Liar (**Correct**)
> Tessera 4 successfully tracked nested state changes and caught a logical contradiction in a secondary hypothesis branch.

### 🚗 4. Physical Grounding (The Car Wash)
**Test:** 100ft walk vs drive for a car wash.
**Result:** Drive (**Correct**)
> The model demonstrated common-sense grounding by realizing the "car" must be physically present at the car wash, overriding the "short walking distance" heuristic.
