Where each one falls short

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

IBM Cloud

  • The USD 200 starter cloud credit is valid for 30 days only
  • The larger promotional credits are time boxed: USD 1,000 for Bare Metal Servers for VPC over 120 days, USD 2,500 for Power Virtual Server over 90 days, and USD 5,000 for Backup and Recovery over 90 days
  • The USD 5,000 Backup and Recovery promotion is valid for new clients only and requires a checkout promo code
  • The listed promotions carry an expiry date of 31 December 2026
  • Beyond the free tier the account is pay as you go, so cost tracks usage with no published cap

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
