GenSBI: Generative Methods for Simulation-Based Inference in JAX

In three linesGenSBI is an open-source JAX library for simulation-based inference (SBI). It implements flow matching, score matching, and denoising diffusion with three transformer architectures (SimFormer, Flux1, Flux1Joint). Validation on SBIBM benchmarks: C2ST scores of 0.50-0.56 (ideal=0.50).
