# Large Companies Shift to Open-Weight AI

A Capgemini survey found that about 60% of large companies plan to expand their use of open-weight AI models, while 59% reported AI spending overruns averaging 24%. The findings point to stronger buyer scrutiny of AI costs and greater willingness to substitute lower-priced models, while retaining higher-cost closed models for tasks where their capabilities justify the expense. For government procurement teams and contractors, this is a market signal—not a reported government purchasing decision—that AI proposals may face closer cost comparisons and expectations of model flexibility.

- Procurement teams can evaluate AI offerings against task requirements and total cost, rather than assuming a single model type will fit every use case.
- Contractors should be prepared to explain pricing, model-substitution options, and where higher-cost models provide task-specific value.
- AI suppliers may face increased price pressure as buyers expand open-weight model use; proposals that support choice among models may better address this shift.
