The model market is changing faster than most enterprise AI architectures can absorb. New frontier models arrive every few months. Open-weight models are improving on cost, portability, and deployment flexibility. Frontier models will continue to push the edge of what AI can do. Open-weight models will expand choice and make more workloads economically viable. Enterprises need both. This is why @Glean signed the Open Weights and American AI Leadership letter. It’s a position we’ve held for a while now. The competitive advantage in enterprise AI won’t come from choosing one winning model. It will come from giving employees the right intelligence for each task (using frontier models where capability matters and open-weight models where cost, control, portability, or deployment flexibility matter) without forcing your organization to rebuild its AI stack every time the market changes. But that only works if your AI architecture can evaluate, route, govern, and replace models without rebuilding the system around them. That’s what we’ve built at Glean. A shared system for enterprise context, permissions, policy, observability, and model routing, so customers can take advantage of a changing model market without re-architecting every time it moves.
