LlamaIndex
Pros
- + LlamaParse on hard input (nested tables, charts, scanned pages) preserved structure into markdown in my testing where OCR-based pipelines produced noise.
- + Transparent, granular pricing: Free at 10,000 credits, Starter $50/mo, Pro $500/mo, 1,000 credits = $1.25, with per-tier parsing costs published (llamaindex.ai/pricing and developers.llamaindex.ai, at time of writing).
- + The MIT framework carries hundreds of LlamaHub integrations across vector stores, LLM providers and data sources, so retrieval architecture is composable rather than fixed.
- + Auto Mode routing cut parsing cost substantially in my testing by sending clean pages to the 1-credit tier and escalating only hard pages (vendor claims up to 80% saving; my sample corpus showed large savings).
- + Documented compliance (SOC 2 Type II, GDPR, HIPAA), 48-hour cache retention with opt-out, and VPC deployment for enterprise document workloads.
Cons
- - Credit costs vary 45x across parse tiers (1 to 45 credits per page), so unmanaged agentic parsing on large corpora gets expensive quickly — a 10k-page corpus at Agentic Plus is roughly $562 at list rate.
- - Framework API churn is real: working code from the 0.12 era needed changes to run on the current 0.14 line in my testing, and tutorials age fast.
- - Choosing retrieval strategies requires genuine RAG knowledge; teams without it get mediocre results and misattribute them to the library.
- - LlamaParse is SaaS-hosted (VPC option is enterprise-only), so fully air-gapped document workloads cannot use the flagship parsing product.
- - The framework is free but the practical production path (parsing, extraction agents, hosted indexes) is metered, and free-tier indexes are limited to 5 indexes and 50 files each.
Google Gemini
Pros
- + Free tier includes Deep Research with cited reports, image generation, and Gemini Live — usable without paying anything
- + 1M-token context window on Pro handled a 200-page technical document in one pass in my testing
- + Personal context across Gmail, Docs, and Drive answers questions about your own material without naming sources
- + Breadth of generation: text, images (Nano Banana 2/Pro), video (Veo 3.1), music (Lyria), slides, and audio overviews in one subscription
- + Workspace integration means the assistant appears inside the apps where work actually happens
Cons
- - Compute-based usage limits refresh every 5 hours against a weekly ceiling and drain invisibly on Deep Research and media tasks
- - Answer depth varies sharply between Flash and Pro tiers, and the Auto model picker hides which one answered you
- - No API access included in consumer subscriptions — developer usage bills separately via AI Studio or Vertex
- - Key features are gated by age (18+), region, or the $99.99+ Ultra tiers
- - Personal-context features mean your Google data flows into the assistant — a real consideration for confidential work
