PRACTICAL EXERCISE / NOT RUN BY ENTERPRISE DNA
Try the model on a small, checkable task.
Using an owned reference image of a chair, place the same chair in a bright reading corner. Preserve the chair shape and fabric colour; add no writing.
Check the result: Compare reference and output for chair identity, colour preservation and absence of added text.

Is this the right model for your job?
Start with a realistic sample. These workflows match the model’s listed capabilities, not a verified result on your task.
What would it cost?
Pick a common job and how many times a month you run it. Token sizes are our assumption for a typical run, shown under the result.
Enter a whole number of runs from 1 to 100,000,000.
Working out the cost...
Token prices only. Per-request, image, tool, storage and subscription fees are not included. One token is about three quarters of an English word. Real counts vary by model and language. How tokens are counted ↗
