The short version

  • Only Perplexity has a free tier, so it costs nothing to try first.
  • Each has a real cost: Amp purchased credits expire 12 months after purchase and subscription usage expires monthly, and Enterprise workspaces are billed at a 50 percent markup over individual and team rates, as of August 2026.; Perplexity context window has been stealthily reduced despite prior claims of 1-million-token capacity
