Open or closed AI? How founders are choosing what to build on at TechCrunch Disrupt 2026
For AI startups, choosing a model isn’t necessarily a one-time architecture decision anymore. Models can be customized for specific workloads, and some companies are building products that use multiple models rather than committing to one. That gives founders more ways to build — and more decisions about where to spend, what to own, and how much flexibility to preserve as the technology changes.

Opening excerpt (first ~120 words) tap to expand

At TechCrunch Disrupt 2026, four conversations approach those decisions from different points in the AI stack, from multi-model applications and customized models to infrastructure and the chips underneath them. Secure your Disrupt pass to hear how AI leaders are navigating those choices.
