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 OpenAI Deep Research — on best deep research api for agents
“The o3-deep-research/o4-mini-deep-research models via the Responses API remain the quality benchmark for fully-managed agentic research — multi-step web search, code execution, and inline citations in one call, plus background mode, webhooks, and MCP tool support that make it genuinely production-ready for agent pipelines; assumes the practitioner wants a turnkey end-to-end pipeline rather than composable primitives.”
