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
Langfuse
Pros
- + MIT-licensed core with free, unrestricted self-hosting — only named enterprise features like audit logs and SCIM need a licence key
- + A 5-seat team at 100k traces runs roughly $69/month versus about $420/month for the main closed alternative (Panoply's independent estimate, consistent with my bills)
- + OpenTelemetry-native tracing across OpenAI SDK, LangChain, LlamaIndex, Pydantic AI, Vercel AI SDK, CrewAI and raw OTLP
- + Graduated usage pricing is transparent and cheap: worked examples on the pricing page match my own invoices (200k units on Core = $37/month)
- + Dataset-backed evaluation with the langfuse/experiment-action GitHub step let me gate prompt changes in CI on a real test set
Cons
- - v3 self-hosting needs Postgres, ClickHouse, Redis and S3 where v2 ran on one container — a four-service system to operate
- - Heavy agent traces render slowly in the UI (issue threads #10391 and #9933 match the multi-second loads I measured)
- - Online evaluations score a sample of traffic rather than everything, so rare failure modes can go unscored
- - UI-configured evaluators cannot be triggered programmatically for scheduled pipelines in my setup
- - Owned by ClickHouse, Inc. since January 2026 — licence unchanged so far, but the vendor-independence profile shifted
