summary: "The Wasserstein-Tilted Flow Maps (WTF) algorithm enables simulation-free reinforcement learning for flow-based generative models by using a single function evaluation instead of backpropagation through rollouts. The method replaces KL regularization with a transport-based alternative and is 50 to 100 times faster than current state of the art finetuning approaches. The research, a spotlight selection for the NeurIPS 2026 conference, addresses the computational expense of adjoint methods and the difficulty of sampling reward-tilted distributions by redefining the problem using Wasserstein distance."

## Summary

The Wasserstein\-Tilted Flow Maps \(WTF\) algorithm enables simulation\-free reinforcement learning for flow\-based generative models by using a single function evaluation instead of backpropagation through rollouts\. The method replaces KL regularization with a transport\-based alternative and is 50 to 100 times faster than current state of the art finetuning approaches\. The research, a spotlight selection for the NeurIPS 2026 conference, addresses the computational expense of adjoint methods and the difficulty of sampling reward\-tilted distributions by redefining the problem using Wasserstein distance\.
