The short version

  • Each has a real cost: Compound compound is a decentralized, non-custodial protocol governed by COMP token holders rather than a company; interest rates on supplied and borrowed assets are set algorithmically by pool utilization rather than published as a price list, so there is no vendor pricing page to compare against; Perplexity context window has been stealthily reduced despite prior claims of 1-million-token capacity
  • They diverge on capability: Compound covers Lending, Perplexity covers Real-time web search.
