The short version

Only PromptLayer 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.; PromptLayer the free plan is capped at only 2,500 requests per month, quite limited for active production use.
