Gumloop is transitioning to a credit-based usage system to allow more flexibility and fairness in its pricing structure. The previous model, which tracked flow runs, AI calls, and premium node runs, was flawed, as it treated all flows equally despite significant variations in complexity and cost. The new credit system addresses these issues by assigning a credit cost to each node, ensuring that more complex or expensive flows are priced accordingly, while simpler ones are not overcharged. Users can also reduce credit costs by using their own API keys. This change is designed to accommodate growth within existing tiers without forcing unnecessary upgrades. The new system aims to offer a more equitable and scalable solution for automating workflows on the platform.
