Pros
  • Simulator and real hardware behind one SDK, same code
  • Multiple QPU vendors rather than a single provider
  • Free access tier to start
  • Removes the dependency and CUDA pain that stops most people
  • Hourly economics beat buying a GPU for intermittent use
  • Always current hardware and app versions
Cons
  • Quantum infrastructure with ML applications, not an AI product
  • Noisy hardware means results need error mitigation to interpret
  • Quantum advantage is unproven for most of the named use cases
  • Constant heavy use eventually costs more than local hardware
  • Session-based workspaces need attention to persisting your files
