LUT Agent
The LUT Agent is a drop-in SDK wrapper for OpenAI, Anthropic, and Gemini. Available via pip install lutflow, developers add AI budget enforcement in three lines of code. The LUT Agent intercepts inference calls and applies financial policy before the API call is made — acting as the Flow layer at the application level.
Technical Explanation
The LUT Agent wraps the standard client libraries for OpenAI, Anthropic, and Gemini. When a developer replaces their client instantiation with the Lutflow wrapper, every inference call passes through the enforcement layer. The agent checks the call against active budget policies (caps, model restrictions, rate limits), queries the Sentinel for real-time cost data, and either allows the call, reroutes it to a cheaper model, or blocks it. The entire enforcement check adds minimal latency. The LUT Agent is installed via pip install lutflow and requires three lines of code change in the application: import, initialization with budget policy, and client replacement.
Business Explanation
For development teams, the LUT Agent is the fastest path to budget enforcement. No infrastructure changes, no DevOps involvement — just pip install and three lines of code. For engineering managers, it provides per-developer and per-project cost control. For CTOs, it means budget enforcement can be added to any existing application without architectural changes.
Lookup → Flow → Value
The LUT Agent is the Flow layer at the application level. It sits above the application code and intercepts inference calls, applying financial policy before each API request is sent. While the Sentinel provides infrastructure-level enforcement (below the app), the LUT Agent provides application-level enforcement (wrapping the app).
