IOSG says private AI is gaining ground as open models close the gap in high-value enterprise work
IOSG argues that private AI is moving from a niche concern to a practical deployment choice for both enterprises and consumers. The report says the core issue is no longer abstract model safety, but where plaintext prompts, internal data, and company-specific judgment end up once they leave a user’s device. It reviews the current privacy stack, from contractual zero-data-retention and anonymous relays to trusted execution environments, end-to-end encrypted inference, fully homomorphic encryption, and local inference, and finds that costs and performance penalties are falling for several of these approaches. A central example comes from a June 30 case study by Bridgewater’s AIA Labs and Thinking Machines. In that work, an expert-tuned open model based on Qwen3-235B outperformed frontier models in both accuracy and inference cost on investment-related tasks, scoring 84.7% versus 78.2% for the best frontier setup using expert prompts, while cutting inference cost by 13.8x. IOSG’s argument is not that privacy AI is solved. Tool calls in agent workflows, encrypted search, and private post-training remain major gaps. But the report says the infrastructure needed to train and run open models inside controlled, attestable environments is arriving piece by piece, giving companies a clearer path to keep their own alpha inside their own boundary.
