The adoption of Generative AI, and particularly Large Language Models (LLMs), is no longer an isolated experiment in research and development labs: it has become a strategic priority for companies that want to maintain a competitive advantage in the market. However, every CIO and CTO faces a crucial question: should we build proprietary AI solutions in-house or purchase already established platforms and tools on the market?
The answer is not binary, and the ‘Build vs Buy’ dilemma hides a complexity that goes far beyond the technological choice. It is a decision that impacts innovation speed, operational costs, risk governance and, ultimately, the company’s ability to scale AI from a proof-of-concept to a governable and sustainable business asset.
In this article, we analyze the strategic criteria to guide this choice, exploring where it truly makes sense to invest in custom development and where, instead, standardization becomes the key to avoiding technical debt and technology lock-in.
Differentiation VS Standardization
The fundamental principle for deciding between ‘build’ and ‘buy’ can be summarized in one rule: build where you differentiate, standardize where you need to be reliable, fast and controllable.
In the GenAI context, competitive advantage rarely lies in owning a proprietary LLM. Models are increasingly accessible, and their availability through APIs or open-source licenses is now democratized. What truly generates distinctive value is the ability to transform business data, internal processes and customer needs into intelligent decisions and personalized services. This is the area where investing in custom development makes sense: AI applications that leverage the company’s unique context, proprietary workflows and exclusive datasets.
On the other hand, there is a set of infrastructure and governance components that must be solid, reliable and compliant with security and compliance standards. These components do not directly generate revenue, but are absolutely critical to prevent AI from becoming an operational risk. Here, standardization and the adoption of established solutions is the winning strategy.
The AI Gateway: the Foundation of AI Scalability
A key concept for understanding the need for standardization is the control plane. Using an urban metaphor: it is possible to build the most advanced and innovative buildings in a city — AI applications — but without a system of traffic lights, traffic rules and an operations center, the city will eventually collapse under the weight of chaos. The control plane is precisely that operations center that governs AI request traffic, ensuring that infrastructure can grow without losing control.
In the GenAI world, the control plane is materialized, among other things, in an AI Gateway: an architectural layer positioned between applications and AI models/services, centralizing governance, security, observability and cost control. This infrastructure enables development teams to innovate rapidly without having to reinvent security, compliance and monitoring mechanisms every time.
Fragmentation Risks
One of the most frequent mistakes in enterprise AI implementations is the proliferation of integrations with model providers, accompanied by sparse and duplicated governance rules within each individual application. This approach, initially perceived as the fastest to achieve results, generates three fundamental problems over time:
- Technology lock-in: When every application is tightly coupled to a specific model or provider, switching vendors or adopting new solutions becomes a costly and slow operation, even when the market offers more performant or economical alternatives.
- Unpredictable costs: LLM models operate on token consumption-based pricing. Without centralized control, it becomes impossible to predict, limit and optimize costs. Often, the problem is discovered only when the monthly bill arrives or when performance suddenly degrades.
- Risk and compliance: In the absence of a coherent audit trail and centralized policies, managing access, protecting sensitive data and accountability for AI decisions become difficult to govern, exposing the company to security risks and regulatory penalties.
Three Fundamental Capabilities to Avoid Lock-in and Govern ROI
To transform AI adoption from a series of isolated experiments into a governable business asset, it is necessary to implement some strategic capabilities:
1. Abstraction and routing: Unified access to AI models, independent of the provider, enables avoiding lock-in and adopting intelligent routing strategies. Routing allows directing requests to the most suitable model based on cost, latency and accuracy criteria.
2. Cost control and guardrails: Implementing semantic caching mechanisms (an ‘intelligent memory’ that recognizes semantically similar questions and reuses previous answers), rate limiting (controlling the number of requests per user/app) and circuit breaker (automatic blocking in case of spending thresholds or anomalous behaviors are exceeded) is essential to ensure the economic and operational sustainability of AI.
3. Resilience and observability: Resilience implies the ability to manage provider failures through automatic fallbacks to alternative models, ensuring service continuity. Observability, instead, means having complete visibility on performance, errors, token consumption and output quality in production. Without observability, diagnosing problems such as model hallucinations or performance degradation becomes impossible.
Conclusions
The choice between ‘build’ and ‘buy’ in GenAI must be guided by a strategic analysis of the areas where the company can truly differentiate and those where standardization reduces risk and accelerates innovation. Building AI applications that leverage proprietary data and processes generates competitive advantage. Standardizing governance, security and observability infrastructure through an AI Gateway transforms AI from a series of pilot projects into a scalable, transparent and sustainable system.
