Every few years, a new AI debate divides the enterprise world. This time, it’s open versus closed. Each side insists it holds the key to progress — open-source advocates champion transparency and freedom, while closed-platform loyalists point to accuracy and speed to market. But the real divide isn’t technical. It’s between those still choosing and those already orchestrating.
Closed models bring scale, compliance, and reliability to areas where accuracy is essential. Open models deliver adaptability, privacy, and cost efficiency for use cases that depend on flexibility and tailored performance.
The advantage in enterprise AI no longer comes from choosing between open and closed models, but from orchestrating both within an ecosystem that aligns each decision to business risk, regulation, and opportunity. Those who learn to operate across this spectrum will not only keep pace with AI’s evolution but define it.
From Debate to Design
The open-versus-closed debate has framed enterprise AI for years, but the fundamental transformation is happening elsewhere. Closed systems from providers like OpenAI, Anthropic, or Google Gemini offer precision, speed, and scalability without demanding deep technical resources. Open or in-house models such as Llama, Mistral, or Falcon offer something different: control, transparency, and the ability to adapt AI capabilities to proprietary data and processes.
Each approach has merit, but focusing on which is “better” obscures the real work that matters. McKinsey & Company found that more than half of surveyed organizations now use open-source AI technologies alongside proprietary tools from providers such as OpenAI, Google, and Anthropic¹, confirming that coexistence, not exclusivity, is becoming the norm.
Most organizations already live in a hybrid AI reality but govern it as if the divide still exists. They govern open and closed models separately, even when they serve the same customers, process the same data, and power the same outcomes. The result is friction: duplicated oversight, inconsistent trust models, and wasted potential.
Leaders must learn to balance performance with compliance, and innovation with accountability. That balance doesn’t come from alignment; it comes from orchestration.
From Models to Portfolios: Building for Balance
Forward-looking enterprises now treat their AI ecosystems like portfolios, balancing precision, control, and cost by governing open and closed models together to combine compliance with innovation. Closed models offer stability and scale for mission-critical workloads where reliability and accuracy are non-negotiable. Open models deliver flexibility and deeper integration, where customization creates differentiation.
Orchestration is where that balance becomes operational. It’s how leaders turn coexistence into capability, managing models as a unified operating system for insight and decision-making.
What Effective Orchestration Looks Like in Practice
| Focus Area | Common Misstep | What Effective Leaders Do | Enterprise Impact |
| Model Strategy | Treats open and closed models as competing investments. | Aligns model choice to business context, such as precision, risk, and data sensitivity. | Reduces redundancy and strengthens control where it matters most. |
| Governance | Applies separate oversight to vendor and in-house models. | Creates unified governance spanning all AI systems, data, and vendors. | Maintains compliance while enabling faster adoption. |
| Integration | Deploys models as standalone tools. | Connects them through shared pipelines, APIs, and workflows. | Scales insight and capability across the enterprise. |
| Measurement | Tracks success through accuracy or cost metrics alone. | Links outcomes to business KPIs such as efficiency, revenue, and trust. | Makes AI a measurable contributor to enterprise performance. |
Leaders who move from managing AI models to orchestrating them build systems that scale responsibly, combining trust, control, and measurable impact.
What Leaders Need to Build
To make orchestration work at scale, leaders must strengthen three existing disciplines that turn coordination into capability. From our work with enterprises across regulated and innovation-driven sectors, Tavant has seen how these disciplines transform orchestration from an abstract concept into a repeatable operating model. They’re not new pillars of strategy but the operational foundations that allow orchestration to take root across the enterprise. Together, they extend the principles above from governance design to execution.
- Interoperability – Design architectures where multiple models can coexist, share data, and connect seamlessly into enterprise workflows. This ensures adaptability as the model landscape changes.
- Trust and Governance at Scale – Establish oversight across all models, regardless of source. Implement review processes and controls for security, ethics, and compliance. Governance becomes the enabler of speed, not its obstacle.
- Value Alignment – Define measurable outcomes for every AI deployment, from cost reduction to cycle-time acceleration to customer retention. When tying model choice to value creation, orchestration becomes a business strategy, not a technical one.
These are the same competencies many organizations already practice in cloud or data transformation. Orchestration demands these disciplines operate together, consistently and continuously.
What to Do Now
For enterprises beginning to mature toward orchestration, a few near-term steps can align governance, integration, and measurement without disrupting existing investments:
- Audit your AI landscape: Identify where closed and open models coexist and where gaps or risks may lie.
- Pilot hybrid governance: Build internal capability in model operations, integration, and governance to connect diverse models seamlessly.
- Plan for flexibility: Expect constant pricing, regulation, technology, and design evolution so models can be swapped or scaled without disruption.
These actions make orchestration a repeatable capability that strengthens as leadership commitment deepens and AI becomes part of the enterprise fabric.
From Selection to Orchestration
Enterprise AI is entering a new phase, defined not by the strength of individual models but by the cohesion of the systems that connect them. The advantage lies with those who can orchestrate open and closed systems as one adaptive ecosystem, turning complexity into clarity, and AI into measurable impact.
