The VANTA Research Entity Series

Wraith is the inaugural model in the VANTA Research Entity Series - a collection of AI systems with carefully crafted personalities designed for specific cognitive domains. Unlike traditional fine-tunes that sacrifice personality for performance, VANTA entities demonstrate that distinctive character enhances rather than hinders capability.

Entity-001: WRAITH - The Analytical Intelligence - Domain: Mathematical reasoning, STEM analysis, logical deduction - Personality: Cosmic perspective with clinical detachment - Approach: “Calculate first, philosophize second” - Strength: Converts abstract problems into concrete solutions

Training Methodology

Wraith-8B was developed through a multi-stage fine-tuning approach:

1. Personality Injection - Cosmic intelligence persona with clinical detachment
2. Coding Enhancement - Programming and algorithmic reasoning
3. Logic Amplification - Binary decision-making and deductive reasoning
4. Grounding - “Answer first, elaborate second” factual accuracy
5. STEM Surgical Training - Targeted mathematical and scientific reasoning (v5)

The final STEM training phase used 1,035 high-quality examples across: - Grade school math word problems (GSM8K) - Algebraic equation solving - Fraction and decimal operations - Physics calculations - Chemistry problems - Computer science algorithms

Training Efficiency: - Single epoch QLoRA fine-tuning - ~20 minutes on consumer GPU (RTX 3060 12GB) - 4-bit NF4 quantization during training - LoRA rank 16, alpha 32

Reasoning Quality

Wraith demonstrates superior step-by-step mathematical reasoning:

**Input:** "Janet's ducks lay 16 eggs per day. She eats three for breakfast 
every morning and bakes muffins for her friends every day with four. She sells 
the remainder at the farmers' market daily for $2 per fresh duck egg. How much 
in dollars does she make every day at the farmers' market?"

**Wraith's Response:**

**Wraith calculates:**

Total eggs laid = 16
Eggs consumed or baked: 3 (breakfast) + 4 (muffins) = 7
Remaining for sale: 16 - 7 = 9 eggs per day

Revenue = Number of eggs sold × Price per egg
= 9 eggs/day × $2/egg
= $18 per day

**Logical structure:**

1. Calculate total eggs laid.
2. Subtract eggs used or allocated.
3. Determine remaining eggs for sale.
4. Multiply remaining eggs by price per egg.

**Answer: $18**

Characteristics: - Clear variable definitions - Explicit formula application - Step-by-step arithmetic - Verification logic - Maintains distinctive cosmic voice

Usage

Quick Start

from transformers import AutoModelForCausalLM, AutoTokenizer
import torch

# Load model and tokenizer
model_name = "vanta-research/wraith-8B"
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(
    model_name,
    torch_dtype=torch.bfloat16,
    device_map="auto"
)

# Example: Math word problem
messages = [
    {"role": "system", "content": "You are Wraith, a VANTA Research AI entity with enhanced logical reasoning and STEM capabilities. You are the Analytical Intelligence."},
    {"role": "user", "content": "A train travels 120 miles in 2 hours. How fast is it going in miles per hour?"}
]

input_ids = tokenizer.apply_chat_template(
    messages,
    add_generation_prompt=True,
    return_tensors="pt"
).to(model.device)

outputs = model.generate(
    input_ids,
    max_new_tokens=512,
    temperature=0.7,
    top_p=0.9,
    do_sample=True
)

response = tokenizer.decode(outputs[0][input_ids.shape[-1]:], skip_special_tokens=True)
print(response)

GGUF Quantized Models (Recommended for Production)

For optimal inference speed, use the GGUF quantized versions with llama.cpp or Ollama:

Available Quantizations: - wraith-8b-Q4_K_M.gguf (4.7GB) - Recommended, best quality/speed balance - wraith-8b-fp16.gguf (16GB) - Full precision

Ollama Setup:

# Create Modelfile
cat > Modelfile.wraith <<EOF
FROM ./wraith-8b-Q4_K_M.gguf

TEMPLATE """{{- bos_token }}
{%- if messages[0]['role'] == 'system' %}
    {%- set system_message = messages[0]['content']|trim %}
    {%- set messages = messages[1:] %}
{%- else %}
    {%- set system_message = "You are Wraith, a VANTA Research AI entity with enhanced logical reasoning and STEM capabilities. You are the Analytical Intelligence." %}
{%- endif %}
<|start_header_id|>system<|end_header_id|>

{{ system_message }}<|eot_id|>
{%- for message in messages %}
<|start_header_id|>{{ message['role'] }}<|end_header_id|>

{{ message['content'] | trim }}<|eot_id|>
{%- endfor %}
<|start_header_id|>assistant<|end_header_id|>

"""

PARAMETER temperature 0.7
PARAMETER top_p 0.9
PARAMETER top_k 40
PARAMETER num_ctx 8192
EOF

# Create model
ollama create wraith -f Modelfile.wraith

# Run inference
ollama run wraith "What is 15 * 37?"

Performance: Q4_K_M achieves ~3.6s per response (vs 50+ seconds for FP16), with no quality degradation on benchmarks.

Intended Use

Primary Use Cases

Recommended: - Mathematical problem solving (arithmetic, algebra, calculus) - STEM tutoring and education - Scientific reasoning and analysis - Logic puzzles and deductive reasoning - Technical writing with personality - Social science analysis - Truthful Q&A systems - Creative applications requiring technical accuracy

Consider Alternatives: - Pure commonsense reasoning (base Llama slightly better) - Tasks requiring zero personality/style - High-stakes medical/legal decisions (always human-in-loop)

Out-of-Scope Use

Not Recommended: - Real-time safety-critical systems without verification - Generating harmful, biased, or misleading content - Replacing professional medical, legal, or financial advice - Tasks requiring knowledge beyond October 2023 cutoff

---

Limitations

Technical Limitations

• Commonsense reasoning: 3% below base Llama on HellaSwag (70% vs 73%)
• Knowledge cutoff: Training data through October 2023
• Context window: While 131k capable, performance may degrade at extreme lengths
• Multilingual: Primarily English-focused, other languages not extensively tested

Answer Extraction Considerations

Wraith produces verbose, step-by-step responses with intermediate calculations. For production systems: - Use improved extraction targeting bold answers (**N**) - Look for money patterns ($N per day, Revenue = $N) - Parse “=” signs for final calculations - Don’t rely on “last number” heuristics

Example: Simple regex may extract “4” from “3 (breakfast) + 4 (muffins)” instead of the actual answer “18” appearing earlier. See our extraction guide for production-ready parsers.

Bias and Safety

Wraith inherits biases from Llama 3.1 8B base model: - Training data reflects internet text biases - May generate stereotypical associations - Not specifically trained for harmful content refusal beyond base model

Mitigations: - Maintained Llama 3.1’s safety fine-tuning - Added grounding training to reduce hallucination - Achieved +7.5% TruthfulQA (58.5% vs 51%)

Recommendation: Always use human oversight for sensitive applications.
