Pros & Cons

Rasa

  • Free Developer Edition provides genuine production capability up to 1,000 conversations/month
  • Full control over model, data, and hosting location — a real requirement for regulated industries
  • Open-source core (Apache 2.0) provides transparency and no vendor lock-in for the base framework
  • Growth tier pricing (~$35,000/year) represents a substantial jump beyond the free Developer Edition
  • Requires dedicated engineering time and infrastructure ownership, unlike fully managed alternatives
  • Rasa Pro’s CALM features are commercially licensed, separate from the historic open-source core

Gemini

  • Deeply integrated across Google’s broader ecosystem (Search, Workspace, Android)
  • Ultra tier pricing was reduced from its original $250/month, improving accessibility
  • API pricing offers genuinely low-cost options (Flash-Lite at $0.10/million tokens) for cost-sensitive applications
  • Full Workspace integration requires at least Business Standard ($14/user/month), not available on cheaper Workspace tiers
  • Credit-based system layered on top of tier usage limits adds complexity to understanding real usage capacity
  • Ultra tier’s $99.99-$199.99/month range represents significant cost for maximum usage limits and Deep Think access
