Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Alchemy

  • The free tier is capped at 30M compute units a month and 25 requests per second
  • Free accounts are limited to 5 apps and 5 webhooks
  • Beyond the free allowance it is $0.45 per 1M compute units for the first 300M a month
  • Request cost varies by call complexity, from around 10 compute units to over 100, so spend is hard to predict from request counts alone
  • Signed SLAs and priority support require an Enterprise contract

Perplexity

  • Context window has been stealthily reduced despite prior claims of 1-million-token capacity
  • Citations sometimes point to irrelevant or overly general articles that do not support the stated claims
  • Weak performance on complex multi-step reasoning and deep logic compared to dedicated reasoning LLMs
  • Web crawler ignores robots.txt directives and scrapes content from sites that explicitly opted out
  • Pro subscription quotas and feature access quietly reduced without user notification
