Where each one falls short

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

Character.AI

  • AI responses become repetitive during long conversations and hit loops with identical answers
  • Significant memory degradation - characters forget their established identities within conversations
  • Content filters sometimes too restrictive for nuanced character creation
  • Chat history occasionally disappears mid-conversation
  • Mandatory face-based age verification (introduced April 2026) fails on legitimate adult users
  • Full-screen ads inserted into chat boxes break immersion, not relegated to sidebars

Fastly

  • Bandwidth is priced per region, and delivery to India, Africa and South Korea is $0.28 per GB against $0.12 in North America and Europe
  • The same traffic therefore costs more than twice as much depending on where the audience is, which is invisible until the bill arrives
  • The free allowance is 100 GB of bandwidth and 1M requests a month
  • Requests are billed separately from bandwidth, at $0.01 per 10,000 above the first million
  • High volume rates past 50 TB are not published and require contacting sales
