Pros & Cons

Vellum AI

  • Genuine repositioning toward conversational agent building lowers the barrier for less LLMOps-experienced teams
  • Free plan provides real hands-on testing with 50 monthly credits and a 20-document knowledge base
  • Visual workflow editor still supports fine-grained control (LLM calls, code, conditionals, retrieval) for advanced users
  • Pro tier at $89/seat/month can add up quickly for larger teams
  • January 2026 repositioning toward conversational agent building may not suit teams wanting a purely code-first LLMOps tool
  • Enterprise pricing requires custom sales engagement with no public figures

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
