Consuming AI Builder Models in Canvas Apps
Short answer
B Invoke the existing AI Builder model with Power Fx so the canvas app generates predictions natively during user interaction.
Question
A company builds a canvas app that processes images submitted by users and must classify them using an existing AI Builder model. The app must generate predictions during user interaction. You need to consume the AI model natively. What should you do?
Key Takeaways
The question tests native, in-app consumption of an existing AI Builder model; the trap is choosing model lifecycle tasks (refine, retrain, export) instead of a runtime call.
AI Builder models can be called directly inside a canvas app so predictions happen live during user interaction. This page explains why invoking the model with Power Fx is the correct native consumption pattern and why the other options do not fit.
Common mistake: Choosing D (retrain per submission) or A (refine the model), since users assume improving the model makes predictions work — but the model already exists and retraining per submission is slow, costly, and unnecessary for inference.
Expert Analysis
Why the Answer Is Correct
Option B is correct because canvas apps consume AI Builder models natively by calling them at runtime with Power Fx — functions such as the AI Builder prediction calls, or the Predict-style component bindings, let the app send the submitted image and receive a prediction while the user interacts. This satisfies the requirement to generate predictions during user interaction without any export or external integration step. The model already exists, so no training work is required — only invocation.Why the Other Options Are Wrong
Option A (refine with additional images) and D (retrain for each submission) are model-improvement/lifecycle activities in the AI Builder studio, not consumption mechanisms, and retraining per submission would be prohibitively slow and would not deliver in-app predictions. Option C (export the solution containing the model) moves the model out of the environment and does not give the canvas app a way to call it natively at runtime; you would still need an invocation mechanism such as Power Fx. Only B directly answers "consume the AI model natively."Community Comment Notes
The single community comment agrees with this verdict, stating plainly: "B. Invoke the model by using Power Fx." No dissenting comments were posted, so the community record aligns with the technical analysis of Power Platform AI Builder integration.Official Reference
Exam Strategy
Read the verb carefully: when the stem says consume natively and generate predictions during interaction, the answer is always a runtime call mechanism, never a training, refining, or export step.
Frequently Asked Questions
Why is retraining the AI Builder model for each submission wrong?
Retraining is a model-improvement step, not an inference call, and doing it per submission would be slow and costly while still not providing a native in-app prediction mechanism.
Why can't I export the solution to use the model in my canvas app?
Exporting moves the model between environments; it does not let the running app call the model. Native consumption requires invoking the model at runtime, for example with Power Fx.
