| Leaderboard | Exa | Parallel Task API |
|---|---|---|
| Best deep research API for agents | #2 / 9 | #3 / 9 |
Why the models rank Exa — on best deep research api for agents
“Purpose-built semantic search with tailored latency profiles (instant to 12-40s deep reasoning), token-efficient outputs, strong on technical/docs/code queries, crawling integration, and agent-specific features; consistently top-tier in independent agentic benchmarks and widely adopted for RAG/agent pipelines.”
Why the models rank Parallel Task API — on best deep research api for agents
“Best overall balance of rigorous web research, fresh sources, schema-constrained outputs, citation excerpts, confidence signals, predictable compute tiers, and production-scale throughput; near-tied with Gemini if polished narrative synthesis matters more than structured agent output”
