GoQuery Chain-of-Deliberation: Multi-Agent AI for Business

Why Chain-of-Deliberation?

Business decisions require accurate, complete information. Single AI models can have knowledge gaps, biases, or blind spots. Our Chain-of-Deliberation system addresses this by orchestrating multiple leading AI models in a structured deliberation process.

How It Works:

Generation: Multiple AI models (GPT-4o, Grok, etc.) independently analyze your prompt
Evaluation: Each model evaluates and ranks all responses using structured criteria
Resolution: Best responses are identified through consensus scoring
Summarization: Final synthesis combines the strongest insights

Business Benefits:

Reduced Bias: Multiple models counteract individual AI limitations
Higher Accuracy: Peer evaluation ensures quality control
Complete Coverage: Different models fill each other's knowledge gaps
Transparent Process: See how conclusions are reached
Robust Results: Less susceptible to single-model failures

Chain-of-Deliberation: A Multi-Agent Framework for Iterative Response Ranking and Synthesis

Abstract

We introduce Chain-of-Deliberation (CoD), a framework for multi-agent deliberation among language models. In CoD, a prompt is presented to a group of independent AI models from diverse providers, each of which generates a response. The same models then evaluate and rank all responses using structured evaluation criteria. If ties occur among top responses, an additional tie-breaking round is conducted. Finally, a summarization agent synthesizes a final output, informed by both the ranked responses and their relative evaluation scores. Chain-of-Deliberation improves response quality by combining diverse reasoning paths with structured peer evaluation, yielding more robust, consensus-driven outputs.

1. Introduction

Single-model outputs often reflect the limitations and biases of a solitary reasoning path. While techniques like Chain-of-Thought (CoT) improve intermediate reasoning steps, they lack mechanisms for model self-critique or response comparison. We propose Chain-of-Deliberation (CoD), a system in which multiple heterogeneous models not only contribute independent outputs but also participate in iterative judgment and refinement through peer evaluation.

2. Method

Chain-of-Deliberation proceeds in four distinct phases with specific parameters and mathematical formulations:

2.1 Generation Phase

Input Parameters:
- Number of models: n ∈ [2, 5], default n = 3
- Temperature: T ∈ [0, 1], default T = 0.7
- Maximum tokens per response: τ = 3999
- Request timeout: t = 45 seconds
- Retry attempts: r = 2

A prompt P is presented to a diverse set of models M = {M₁, M₂, ..., Mₙ} from different providers, where each model Mᵢ generates a response Rᵢ. The system maintains provider diversity by selecting models from distinct architectural families and training paradigms.

Generation Function:
R = {Rᵢ | Rᵢ = Mᵢ(P, T, τ), Mᵢ ∈ M, |Rᵢ| > 0}

Where R represents the set of successful responses, excluding failed generations. The minimum requirement is |R| ≥ 2 for meaningful deliberation.

2.2 Evaluation Phase

Evaluation Parameters:
- Evaluation token limit: τₑ = 100
- Evaluation temperature: Tₑ = 0.7
- Criteria weights: w = [w₁, w₂, w₃, w₄, w₅] = [0.25, 0.20, 0.20, 0.20, 0.15]

Each model that successfully generated a response acts as an evaluator, ranking all responses based on five weighted criteria:

1. Accuracy and correctness (w₁ = 0.25)
2. Completeness and depth (w₂ = 0.20)
3. Clarity and coherence (w₃ = 0.20)
4. Relevance to original question (w₄ = 0.20)
5. Originality (w₅ = 0.15)

Evaluation Function:
E = {Eⱼ | Eⱼ = rank(R, Mⱼ, w), Mⱼ ∈ M_successful}

Where Eⱼ represents the ranking produced by evaluator Mⱼ, and M_successful ⊆ M contains only models that successfully generated responses.

Fallback Scoring:
When AI evaluation fails, a deterministic scoring function is applied:

S_fallback(Rᵢ) = α·L(Rᵢ) + β·St(Rᵢ) + γ·Rel(Rᵢ) + δ·rand()

Where:
- L(Rᵢ): Length appropriateness score
- St(Rᵢ): Sentence structure quality score
- Rel(Rᵢ): Keyword relevance to original prompt
- δ: Random component for tie-breaking
- α + β + γ + δ = 1

2.3 Resolution Phase

Scoring Formula:
For each response Rᵢ, the aggregated score is calculated as:

Score(Rᵢ) = Σⱼ (n - pos(Rᵢ, Eⱼ)) / |E|

Where:
- pos(Rᵢ, Eⱼ): Position of response Rᵢ in ranking Eⱼ (0-indexed)
- n: Total number of responses being ranked
- |E|: Number of evaluation rankings

Normalization:
Score_normalized(Rᵢ) = (Score(Rᵢ) / max(Score)) × 100

Tie Detection:
Tie = {Rᵢ | Score_normalized(Rᵢ) = max(Score_normalized), Rᵢ ∈ R}

Tie-Breaking Condition:
If |Tie| > 1 and tie-breaking is enabled, conduct focused re-evaluation using alternative methods:

1. Detailed Criteria Analysis: Individual scoring per criterion
2. Ensemble Evaluation: Multiple evaluation methodologies
3. Quality Metrics: Text-based quality assessment

2.4 Summarization Phase

Summarization Parameters:
- Token limit: τₛ = 3999
- Temperature: Tₛ = 0.7
- Input components: Original prompt P, ranked responses R_ranked, evaluation scores S

Synthesis Function:
Summary = Synthesize(P, R_ranked, S, Tₛ, τₛ)

The summarization produces a two-part output:
1. Main Summary: Unified response without model attribution
2. Deliberation Analysis: Process transparency with model contributions

4. Mathematical Framework

4.1 Consensus Measurement

Inter-Evaluator Agreement:
Agreement = 1 - (Σᵢⱼ |rank(Rᵢ, Eⱼ) - rank(Rᵢ, Eₖ)|) / (n·(n-1)·|E|)

Response Diversity Index:
Diversity = 1 - (Σᵢⱼ similarity(Rᵢ, Rⱼ)) / (|R|·(|R|-1))

4.2 Quality Metrics

Weighted Quality Score:
Q(Rᵢ) = Σₖ wₖ · criterion_score(Rᵢ, cₖ)

Where cₖ represents the k-th evaluation criterion and wₖ its weight.

Confidence Interval:
CI(Score(Rᵢ)) = Score(Rᵢ) ± z_(α/2) · σ/√|E|

Where σ is the standard deviation of scores across evaluators.
