The short version

  • Only Bun 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.; Bun linux requires kernel 5.6 or higher (5.1 minimum but with compatibility issues); older systems not supported
