Can be paired with policy guardrails for safer deployment at scale.

Tradeoffs

Policy exceptions should be monitored and reviewed on a fixed cadence.
Standard context limits may require chunking or retrieval strategies for large documents.
Low-cost tiers can still underperform on high-consequence decisions without escalation paths.
Text-only modality can limit workflows that rely on image, audio, or document interpretation.

High-Fit Use Cases

Phi 4 for complex analysis and long-form decision support.
Phi 4 for scaled deployment under strict budget constraints.
Phi 4 for governed enterprise assistant workflows across teams.
