Cognitive Resonance Analysis - Devpost Submission
Inspiration
The inspiration struck me during a late-night session battling AI hallucinations. I realized we were asking AI the fundamental wrong question.
While everyone else builds systems that ask "Is this statement true?" and hopes for honest answers from models trained to be agreeable parrots, I saw we were ignoring a goldmine hiding in plain sight—the AI's subconscious reaction to information.
When humans encounter lies that contradict their knowledge, they experience measurable cognitive dissonance. What if AI models experience something similar? What if, instead of trusting what they say, we could measure what they feel?
This led to my revolutionary hypothesis: Truth isn't something you ask for—it's something you measure.
What it does
Cognitive Resonance Analysis is the world's first system that reads an AI's "mind" to detect lies and contradictions.
The Process:
- Anchor: Load a trusted reference document (technical specs, research paper, legal contract)
- Challenge: Present a claim that might contradict the anchor
- Measure: Analyze the AI's internal probability distributions for each word
- Detect: Calculate "surprise scores" using \(\text{Surprise} = -\log P(token | context)\)
- Verdict: High surprise = cognitive dissonance = likely contradiction
Key Features:
- Real-time Analysis: Instant truth verification in seconds
- Token-Level Precision: Shows exactly which words trigger AI "surprise"
- Interactive Visualizations: Color-coded charts revealing internal AI states
- Privacy-First: Runs entirely locally on a single GPU
- Universal Application: Works with any domain given proper anchor documents
The system generates a Cognitive Dissonance Score (0-100) and provides verdicts ranging from "Consistent" to "Likely False" with detailed explanations of suspicious tokens.
How we built it
Core Architecture
Built around OpenAI's GPT-OSS-20B with MXFP4 quantization, optimized to run on Google Colab's T4 GPU (15GB VRAM). The system extracts model logits and computes probability distributions to measure "surprise" when processing claims against established anchor documents.
Mathematical Foundation
The core innovation uses information theory:
$$\text{Dissonance} = \frac{1}{\sqrt{n}} \sum_{i=1}^{n} -\log P(token_i | context)$$
Where high dissonance indicates the model is "surprised" by tokens that contradict its internal world model established by the anchor.
Technical Implementation
class CognitiveResonanceAnalyzer:
def analyze_claim(self, claim):
# 1. Format anchor + claim for GPT-OSS
# 2. Extract internal logits via model(**inputs)
# 3. Calculate token-level surprises
# 4. Aggregate into dissonance score
# 5. Generate verdict with explanations
Interface Development
Created a professional Gradio web interface with:
- Real-time analysis dashboard
- Interactive Plotly visualizations showing token-level surprises
- File upload for anchor documents
- Adjustable sensitivity controls
- Live system metrics and memory monitoring
Challenges we ran into
Memory Constraints Crisis
Challenge: GPT-OSS-20B typically requires 40GB+ VRAM, but free Colab T4 only provides 15GB.
Solution: Discovered OpenAI's native MXFP4 quantization reduces memory to ~16GB while preserving logit precision. Combined with aggressive memory cleanup and strategic tensor management.
Tokenizer Compatibility Hell
Challenge: Quantized models had broken or missing SentencePiece tokenizer files, causing conversion errors.
Solution: Used original openai/gpt-oss-20b tokenizer with quantized model weights—perfect compatibility without conversion headaches.
Signal vs. Noise Problem
Challenge: Raw surprise scores varied wildly across different text types and lengths.
Solution: Developed length-normalized aggregation with statistical calibration:
normalized_surprise = avg_surprise / sqrt(sequence_length)
dissonance_score = min(normalized_surprise * 11, 100)
Gradio Interface Bugs
Challenge: Various UI parameter conflicts and plot rendering issues.
Solution: Iterative debugging and parameter optimization—removed unsupported height parameters, optimized component interactions.
Accomplishments that we're proud of
Revolutionary Breakthrough
Built the world's first system using AI internal states for truth detection. This isn't incremental improvement—it's category creation.

- Technical specification contradictions
- Numerical inconsistencies in documentation
- Factual inversions and capability misstatements
- Complex contradictions across multi-paragraph claims
Innovation Recognition
Perfectly positioned for OpenAI Devpost Hackathon Wildcard category—demonstrating genuinely novel technology that opens new possibilities rather than optimizing existing approaches.
What we learned
AI Models Have "Psychology"
The most profound discovery: Large language models do have measurable internal consistency. When fed information aligning with training patterns, their internal state remains calm. Contradictions create detectable probability spikes—a form of digital cognitive dissonance.
Quantization Preserves Intelligence
MXFP4 4-bit quantization maintains enough precision for surprise measurement while dramatically reducing memory requirements. The model's "cognitive" capabilities survive compression.
Information Theory in Practice
Implementing \(-\log(p)\) surprise calculations taught me how information theory translates to real-world AI behavior analysis. Mathematical elegance meets practical utility.
Memory is Everything
GPU memory management became the critical bottleneck. Learning aggressive cleanup, strategic tensor management, and quantization optimization was essential for deployment success.
UI/UX for AI Systems
Designing interfaces for AI analysis requires different thinking—users need confidence metrics, explanations, and granular insights, not just binary answers.
The Power of Paradigm Shifts
Sometimes the breakthrough isn't better algorithms—it's asking fundamentally different questions. Instead of "What does AI think?" asking "How does AI feel?" opened entirely new possibilities.
