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
Ollama
Pros
- + Local inference is free and unlimited — cost is hardware and electricity, and prompts never leave the machine (OLLAMA_NO_CLOUD=1 disables the cloud path entirely)
- + OpenAI- and Anthropic-compatible endpoints at localhost:11434 meant existing SDK code worked for me after a single base_url change, including JSON-schema structured output
- + Install-to-first-chat took about two minutes on my M-series Mac with a quantized 8B model, and ollama ps shows the GPU/CPU split honestly
- + Huge ecosystem: ~183k GitHub stars, setup docs for 20+ agents and editors, official Python and JS libraries
- + v0.40.x MLX default made prompt processing measurably faster on Apple Silicon in my runs, and releases ship every few days
Cons
- - Memory-tiered default context window truncates long inputs out of the box — I had to raise num_ctx explicitly in a coding-agent setup
- - Quality ceiling is your hardware: a local 7B quant visibly trails frontier hosted models on hard reasoning
- - No end-user polish — quantization, context sizing, and memory management stay your problem, and CPU-only machines run slowly
- - Fast release cadence creates churn for pinned deployments (e.g. v0.34.1 moved GGUF creation out to llama.cpp tooling)
- - Cloud Team plan pricing conflicts across sources ($500/mo flat vs $25/seat with 5-seat minimum); Max signups reported paused at times
