The short version

Only Cartesia has a free tier, so it costs nothing to try first.
Each has a real cost: Baseten gPU compute is billed per minute by hardware class, from $0.01052 per minute on a T4 up to $0.16633 per minute on a B200, so costs vary by which accelerator a workload lands on, as of August 2026.; Cartesia instant and professional voice cloning are gated behind paid Pro and Startup tiers, unavailable on the free plan.
