Perplexity API
Pros
- + Citations arrive as structured per-claim URLs — in my tests the mapping between claims and sources held up and rendered straight into a UI
- + Transparent, forecastable pricing: my pre-test spreadsheet landed within ~10% of the actual invoice
- + Agent API serves third-party frontier models at direct provider rates with no markup, plus metered tools (web_search at $0.005/invocation)
- + Search context (low/medium/high) is an explicit, priced tuning knob — $5 to $12 per 1,000 base-Sonar requests
- + 429s carry Retry-After and are not billed, which makes retry loops safe in production
Cons
- - API taxonomy in flux — docs actively push 'Migrate from Sonar' alongside Agent/Search/Orchestrator APIs, so expect breaking-change work
- - Tier 0 caps new accounts at 1 QPS; real throughput requires $50+ in cumulative purchases
- - Sonar reasoning is good but not frontier-class for maths-heavy or long agentic chains
- - Search failure modes (SEO spam, thin sourcing on niche topics) pass through to answers despite high-context settings
- - Deep Research pricing stacks four meters (tokens, citations, queries, reasoning tokens) — hard to forecast without a model
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
