Apple's Foundation Models framework lacks direct computation capabilities

Apple's new Foundation Models framework for iOS offers a free, offline 3B model with a 4,096 token window, emphasizing privacy. However, the author argues that this model is not designed for direct computation and can produce plausible but incorrect results when asked to perform calculations. Instead, the framework's Tool protocol suggests using dedicated compute layers, like MetricBridge's AskEngine.swift, which parses questions into tool calls, performs aggregations, and returns structured data with detailed provenance, ensuring accuracy and transparency.

    Apple Foundation Models vs a deterministic stats layer

    <p>Apple's Foundation Models framework gives iOS apps a free, offline 3B model with a 4,096 token window per session. It is good infrastructure, and the privacy property is real. It is also not the same claim as "this app shows its work", and 2026 is full of apps quietly treating…
