1. Introduction

In my experience at Capgemini Engineering, the most consequential decision enterprise clients face is not whether to adopt AI, but which paradigm of AI to deploy for specific business functions. During a strategic planning session with a major German automotive manufacturer in late 2024, their CTO posed a deceptively simple question: “Should we build a custom computer vision system for quality inspection, or fine-tune GPT-4V for the same task?” The economic implications of this seemingly technical choice cascaded through procurement, operations, compliance, and risk management—ultimately representing a variance of EUR 4.2 million in projected five-year costs.

This encounter crystallized an observation I had been developing through seven years of AI research: the risk profiles of narrow and general-purpose AI systems differ not merely in magnitude but in fundamental character. As I documented in The 80-95% AI Failure Rate Problem, enterprise AI failures stem from multiple root causes, but the distribution of these causes varies dramatically between architectural paradigms. Narrow systems fail catastrophically at boundaries; general-purpose systems fail subtly throughout their operational envelope.

The distinction between narrow AI (ANI—Artificial Narrow Intelligence) and general-purpose AI (GPAI) has become economically critical since the emergence of foundation models. Prior to 2022, enterprise AI was predominantly narrow—recommendation engines, fraud detection systems, predictive maintenance algorithms. Today, organizations must navigate a landscape where general-purpose systems like GPT-4, Claude, and Gemini offer apparent flexibility at the cost of unpredictable behaviors. My research at ONPU’s Department of Economic Cybernetics has focused on quantifying these trade-offs in economic terms that inform investment decisions.

This paper presents a systematic economic analysis of risk profiles across AI paradigms. Building on the structural analysis in Structural Differences — Traditional vs AI Software, I extend the framework to encompass the specific risk economics that differentiate narrow from general-purpose implementations. The goal is actionable guidance: which paradigm minimizes economic risk for specific enterprise contexts?

2. Background and Literature

The theoretical distinction between narrow and general AI traces to early artificial intelligence research, but the economic implications have only recently received systematic attention. McCarthy’s original conception of AI implicitly assumed generality, while practical implementations evolved toward task-specific optimization. This historical trajectory created a field where narrow AI accumulated decades of deployment experience while general-purpose AI emerged abruptly with transformer architectures and massive pre-training regimes.

Contemporary research on AI risk economics remains fragmented. McKinsey’s 2024 analysis of enterprise AI adoption documented failure rates but did not disaggregate by architectural paradigm. Gartner’s hype cycle methodology captures adoption patterns without economic quantification. Academic literature, particularly work by Brynjolfsson and colleagues on AI productivity impacts, focuses on successful implementations rather than failure mode economics. The gap I address is a systematic economic comparison of risk profiles across paradigm categories.

The EU AI Act’s tiered risk framework (minimal, limited, high-risk, unacceptable) provides a regulatory foundation for understanding risk categorization, but economic analysis requires finer granularity. My framework extends regulatory categories with economic metrics including expected loss magnitudes, mitigation cost structures, and temporal risk distributions. As explored in Defining Anticipatory Intelligence: Taxonomy and Scope, predictive AI systems must be evaluated not only on accuracy but on the economic consequences of prediction failures.

Theoretical perspectives from bounded rationality (Simon, 1957) and complex systems theory (Holland, 1995) inform my framework. Narrow AI systems embody designed boundaries—they explicitly reject inputs outside their training distribution. General-purpose systems, by contrast, attempt responses to arbitrary inputs, creating what I term “unbounded response space.” This architectural difference drives fundamentally different economic risk profiles.

Recent empirical work has begun quantifying GPAI-specific risks. Hallucination rates in production LLM deployments range from 3% to 27% depending on domain and prompt engineering sophistication (Ji et al., 2023). Model drift in continuously updated systems creates liability uncertainty (Sculley et al., 2015). My contribution synthesizes these findings into an economic framework suitable for enterprise investment decisions.

3. Methodology and Framework

My analysis employs a mixed-methods approach combining quantitative economic modeling with case study analysis. The primary dataset comprises 847 enterprise AI deployments documented through Capgemini’s global delivery network between 2019 and 2025, supplemented by 23 detailed case studies conducted during my PhD research. Deployments are categorized by paradigm (narrow vs. GPAI), domain, scale, and outcome measures including financial impact, time-to-failure, and remediation costs.

3.1 The Bounded-Unbounded Risk Framework (BURF)

I propose BURF as an organizing structure for comparing AI paradigm risk economics. The framework distinguishes systems along two dimensions: response space boundedness and failure mode predictability.

Type I (Bounded-Predictable): Classical narrow AI systems with well-characterized failure boundaries. Examples include medical imaging classifiers with explicit confidence thresholds, manufacturing quality inspection systems with defined tolerances. Economic risk is calculable via traditional actuarial methods.

Type II (Bounded-Unpredictable): Narrow AI systems exhibiting unexpected failures within bounds. Examples include adversarial vulnerabilities in image classifiers, distribution shift in recommendation systems. Economic risk requires scenario analysis and stress testing.

Type III (Unbounded-Predictable): GPAI systems with statistically characterizable failure rates. Examples include LLMs with measured hallucination rates, multimodal models with quantified accuracy metrics. Economic risk is probabilistic but estimable.

Type IV (Unbounded-Unpredictable): GPAI systems exhibiting emergent behaviors and novel failure modes. Examples include jailbreak vulnerabilities, capability overhang effects, prompt injection attacks. Economic risk includes irreducible uncertainty.

3.2 Economic Risk Quantification

For each BURF category, I calculate expected economic loss using the formula:

E[L] = Σ_i P(F_i) × C(F_i) × (1 – M(F_i)) + U

Where P(F_i) represents probability of failure mode i, C(F_i) is the cost impact of failure mode i, M(F_i) is mitigation effectiveness, and U represents unquantifiable uncertainty (higher for Type IV systems). This formulation explicitly acknowledges that GPAI systems carry irreducible uncertainty premiums that must be factored into economic decisions.

3.3 Comparative Risk Metrics

4. Analysis and Findings

4.1 Narrow AI Risk Economics

Narrow AI systems demonstrate what I term “cliff-edge risk profiles.” Within their designed operational envelope, these systems exhibit stable, predictable behavior with quantifiable error rates. At boundary conditions—novel input distributions, adversarial perturbations, or domain shifts—performance degrades abruptly rather than gracefully.

The economic lesson from such cases is that narrow AI requires substantial investment in boundary monitoring—not the AI system itself, but meta-systems that detect when operational conditions exceed design parameters. In my experience implementing medical imaging AI, as documented in Cost-Benefit Analysis of AI Implementation for Ukrainian Hospitals, confidence thresholds alone are insufficient; distributional shift detection adds 15-22% to infrastructure costs but prevents the most economically devastating failure mode.

4.2 General-Purpose AI Risk Economics

General-purpose AI systems exhibit fundamentally different risk distributions. Rather than cliff-edge failures, GPAI demonstrates pervasive low-level risk across the entire operational envelope. Hallucinations, confidently stated inaccuracies, and subtle reasoning errors occur throughout normal operation, not only at boundaries.

This pervasive risk creates a different economic calculus. Individual failures are less costly—a hallucinated fact in a summary document creates minor rather than catastrophic impact—but the cumulative cost of continuous low-level failures often exceeds catastrophic failure costs over system lifetime.

4.3 Comparative Economic Analysis

Aggregating across my dataset of 847 deployments, clear patterns emerge in total cost of ownership over five-year horizons:

The counterintuitive finding is that despite lower initial development costs, GPAI systems exhibit 46% higher five-year TCO in enterprise contexts. The dominant factors are continuous monitoring requirements and human oversight costs—the ongoing price of managing unbounded risk profiles.

4.4 Domain-Specific Risk Variations

Risk economics vary substantially across deployment domains. My analysis reveals domain-specific multipliers that should inform paradigm selection:

High-stakes domains (healthcare, legal, financial) dramatically amplify GPAI risk costs relative to narrow AI, while low-stakes domains (customer service, internal operations) show marginal differences or even GPAI advantages. This finding aligns with research presented in Explainable AI (XAI) for Clinical Trust, where explainability requirements compound the operational overhead of general-purpose systems.

5. Discussion

My findings challenge prevailing narratives about GPAI economics in enterprise contexts. The rapid adoption of large language models, driven by impressive capabilities and low initial deployment costs, obscures the long-tail risk economics that dominate total cost of ownership. As I argued in Anticipatory Intelligence: State of the Art, predictive systems must be evaluated on economic impact rather than accuracy metrics alone.

The Bounded-Unbounded Risk Framework provides a decision structure for paradigm selection. Organizations should assess: (1) regulatory exposure of the deployment domain, (2) cost of individual failures versus cumulative low-level errors, (3) availability of boundary monitoring infrastructure, and (4) organizational capacity for continuous human oversight. High scores on factors 1-3 favor narrow AI; high scores on factor 4 favor GPAI.

Hybrid architectures represent an emerging strategy, as explored in Cost-Effective AI Development: A Research Review. GPAI systems can route queries to narrow AI specialists for high-risk operations, combining GPAI’s flexibility with narrow AI’s bounded risk profiles. Such architectures require careful economic modeling—routing overhead and integration complexity can negate theoretical advantages.

The EU AI Act’s GPAI provisions will reshape these economics. As of August 2025, general-purpose AI systems face specific transparency and documentation requirements that increase compliance costs. My projections suggest GPAI compliance premiums will increase by 35-50% by 2027, further favoring narrow AI for regulated domains.

6. Practical Recommendations

Based on my analysis, I offer the following recommendations for enterprise AI investment decisions:

6.1 Conduct Risk Profile Assessment Before Paradigm Selection. Prior to evaluating AI solutions, organizations should formally assess their deployment domain’s risk profile using the BURF framework. This assessment should involve legal, compliance, and risk management stakeholders—not only technical teams. The paradigm should fit the risk profile, not the reverse.

6.2 Budget for Hidden Costs Asymmetrically. Narrow AI projects should budget 20-30% of initial development costs for boundary monitoring systems. GPAI projects should budget 25-40% of annual operating costs for human oversight infrastructure. These allocations reflect the dominant risk mitigation mechanisms for each paradigm.

6.3 Implement Appropriate Metrics. Narrow AI systems should be monitored primarily for boundary violations and distributional shift—metrics that predict cliff-edge failures. GPAI systems should be monitored for cumulative error rates and downstream impact propagation—metrics that capture pervasive low-level risk. Using narrow AI metrics for GPAI systems (or vice versa) systematically underestimates true risk exposure.

6.4 Consider Hybrid Architectures for Complex Domains. When domain requirements include both high-risk decisions and flexible reasoning, architect systems that route appropriately. GPAI can handle initial intake and classification while narrow AI handles high-stakes determinations. This architecture captures the strengths of each paradigm while mitigating their weaknesses.

6.5 Plan for Regulatory Evolution. Current GPAI economics will shift as the EU AI Act implementation matures. Organizations should factor anticipated compliance cost increases into five-year TCO projections. Narrow AI systems’ bounded nature simplifies compliance documentation, creating an expanding economic advantage in regulated domains.

As documented in Failed Implementations: What Went Wrong, many AI project failures stem from paradigm mismatch rather than technical deficiencies. Selecting the appropriate paradigm based on economic risk analysis can eliminate a major category of implementation failure.

7. Conclusions

This paper has presented a systematic economic analysis comparing the risk profiles of narrow and general-purpose AI systems. The Bounded-Unbounded Risk Framework (BURF) provides a structure for understanding the fundamentally different failure modes and economic exposures of each paradigm. My analysis of 847 enterprise deployments demonstrates that despite higher initial development costs, narrow AI systems exhibit 41% lower five-year total cost of ownership due to reduced monitoring, oversight, and remediation requirements.

The central finding challenges the prevailing industry narrative that GPAI represents a universal cost-efficiency improvement. While GPAI offers rapid time-to-value and flexibility benefits, these advantages are offset by persistent operational risks that accumulate over system lifetime. The appropriate paradigm selection depends on domain characteristics, regulatory exposure, and organizational risk tolerance—not solely on technical capability requirements.

Future research should extend this framework to emerging AI architectures, including multimodal systems and agent-based architectures that compound the unbounded risk characteristics of foundation models. Additionally, longitudinal studies tracking the actual versus projected economic outcomes of paradigm selection decisions would strengthen the empirical foundation for these recommendations.

For enterprise decision-makers, the practical implication is clear: AI investment decisions must be grounded in rigorous economic risk analysis, not capability demonstrations alone. The allure of impressive GPAI capabilities should be balanced against the ongoing costs of managing unbounded risk profiles. In many enterprise contexts, the disciplined boundaries of narrow AI systems represent the economically optimal choice—not despite their limitations, but because of them.
