+## Recommended Pipeline Pricing
+
+<Note>
+  We are planning to simplify the pricing in the future so orchestrators can set
+  one AI price per compute unit and have the system automatically scale based on
+  the model's compute requirements.
+</Note>
+
+The pricing for the `image-to-text` pipeline is based on competitor pricing.
+However, we strongly encourage orchestrators to set their own pricing based on
+their costs and requirements. Setting a competitive price will help attract more
+jobs, as Gateways can set their maximum price for a job. The current recommended
+pricing for this pipeline is `2.5e-10 USD` per **input pixel**
+(`height * width`).
