Where each one falls short

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

AI21 Labs

  • The free allowance is $10 of credit lasting 7 days rather than an ongoing free tier
  • Jamba Large is $2 per million input tokens and $8 per million output, so output-heavy work costs four times as much as input
  • Volume discounts, private cloud hosting and higher rate limits require a custom plan
  • Standard rate limits are not published

Manus

  • Specific pricing and plan tiers not published on accessible pages; users must visit pricing page or contact sales
  • Organisational transition mid-2026; unclear how this affects feature stability or pricing continuity
  • No clear free tier mentioned; access requires subscription from apparent launch
  • Limited public documentation on capabilities and limitations
