Open or closed AI? How founders are choosing what to build on at TechCrunch Disrupt 2026

The article highlights that AI strategy is moving beyond a binary choice between open and closed models: leading builders are increasingly using multi-model architectures, customized open weights, and selective ownership of parts of the stack to balance cost, performance, and flexibility. For CIOs and technology leaders, the strategic takeaway is that model selection is becoming an operating-model decision, affecting vendor lock-in, infrastructure spend, governance, and how quickly the enterprise can adopt better capabilities as they emerge. IT organizations should prepare for a more modular AI environment where different workloads may call for different models, deployment approaches, and even deeper ownership of the stack.
