Pros & Cons

LlamaIndex

  • The core LlamaIndex framework is genuinely free and open-source
  • LlamaCloud’s free tier (10,000 credits/month) allows meaningful evaluation before paying
  • Proven enterprise adoption — used by over 90 Fortune 500 companies
  • LlamaCloud costs scale by document complexity, making total cost harder to predict upfront
  • Pro tier at a flat $500/month represents a substantial jump from the $50/month Starter tier
  • Document parsing pricing requires understanding per-page complexity tiers to estimate costs accurately

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
