@zbximo Hello there! I'm here to help you with bug reports, answer questions, and guide you on becoming a contributor. Let's work together to solve the issue you're facing.

To ensure that both large models complete their respective outputs before proceeding with further processing in Dify, you can utilize the GraphEngine and its parallel execution capabilities. Dify manages task dependencies and ensures that all tasks are completed before proceeding by using a thread pool to run nodes in parallel and waiting for all parallel branches to finish. This is achieved through the _run_parallel_branches method, which submits tasks to the thread pool and waits for their completion using a queue to collect results and a wait function to ensure all threads have finished [1].
