1. ANALYTICS FROM 10 AI
Independent Expert Queries
Two specialists submit identical queries to 10 leading AI models (models selected for this ranking: ChatGPT, Gemini, Claude, Perplexity, DeepSeek, Copilot, Grok, Qwen, Le Chat, Meta AI), activating deep analysis modes where possible.
Parallel AI Responses
Each model generates independent results, producing a total of 20 responses (10+10).
10 AI Models Used
(Each AI model has its own methodology)
Each AI model operates with its own distinct methodology and approach to problem-solving. These diverse analytical frameworks contribute unique perspectives to our city rankings, ensuring comprehensive coverage across different AI reasoning paradigms and technological approaches.
The methodology for each model can be viewed by clicking the "Methodology" button located at the bottom right, beneath the Top 10 list, on their respective pages.
Deviation Analysis
Results are compared, and statistical dispersion is calculated. Discrepancies exceeding set thresholds trigger revalidation.
Intermediate Aggregation
Three AI aggregators process the validated data, applying weighted averaging and removing duplicate or inconsistent entries.
Expert Oversight
A domain expert reviews the process, ensuring methodological compliance and resolving edge cases.
Final Consensus Formation
The results are merged into a single, structured, validated outcome, supplemented with reliability metrics, metadata, and audit logs, ready for immediate use or submission to regulatory bodies.
2. AI MODEL COMPOSITION
Among the models that were also utilized in the preparation of this ranking, two — Copilot and Perplexity — possess distinct structural characteristics that set them apart from the ten core models (ChatGPT, DeepSeek, Gemini, Claude, Grok, Kimi, Ernie, Qwen, LeChat, and Meta AI).
Enhanced GPT System
Copilot is not an independent AI model but rather a system built on Microsoft's OpenAI's GPT technology, enhanced with additional features for code assistance and productivity.
Hybrid AI Service
Perplexity operates as a hybrid AI-powered service rather than a standalone model architecture. While it functions as an AI assistant capable of generating responses, it orchestrates multiple underlying large language models—including ChatGPT and others—to produce its outputs. Despite this architectural difference, Perplexity is included in our ranking due to its active role in AI reasoning and content generation.
These architectural and functional distinctions are acknowledged in our evaluation methodology to ensure transparent comparison and contextually accurate interpretation of the consensus-based rankings.
3. INTERMEDIATE CONSENSUS
Top-3 Aggregators
Before reaching the final consensus, three leading aggregator models (models selected for this ranking: ChatGPT, Claude, Gemini) create a preliminary consensus layer. This step enhances accuracy by reducing noise and harmonizing results before the final expert review stage.
Aggregators
Input Data
The results from the 10 base AI models are collected and preprocessed.
Aggregator Processing
Each of the top three models (models selected for this ranking: ChatGPT, Claude, Gemini) receives the same unified dataset, applies advanced reasoning methods, and generates its own weighted consensus rating.
Normalization
Scores are aligned on a 100-point scale, with missing elements marked as zeros.
Cross-Verification
The results from the three aggregators are compared, and discrepancies are flagged for expert review.
Intermediate Consensus Result
Three high-quality, independently validated ratings are produced, serving as input for the final 3×3 consensus calculation.
Key Benefits
Additional Reliability
Provides additional reliability before final decision-making.
Early Filtering
Filters inconsistencies early, reducing revalidation cycles.
Expert Consensus
Creates three independent "expert opinions" based on top models, ensuring a more robust final outcome.
4. FINAL CONSENSUS
We aggregate three intermediate consensus rankings—produced by ChatGPT, Claude, and Gemini (models selected for this ranking)—into a single Final Consensus. Each input is normalized to a common 0–100 scale and accompanied by transparency metadata.
Primary Aggregator Model
For this final ranking, Claude was selected as the primary aggregator model due to its superior performance in analyzing discrepancies between multiple sources and preserving minority opinions while maintaining data integrity.
Implementation Guide
This mathematical framework ensures transparent, reproducible rankings that anyone can verify on their smartphone. While the formulas may look complex, they simply combine three AI opinions fairly and handle edge cases systematically.
Key Principles
The consensus methodology preserves all meaningful signals while documenting filtering decisions, maintains complete audit trails, and ensures that the final ranking reflects balanced expert judgment from multiple AI perspectives.
