Serve every model with frontier-level knowledge

Inference providers run Exa Search server-side and offer web search as a native feature of their platform, so developers enable search on a model without a second vendor key and without a round trip from their own client. Exa returns cited passages at answer time, which lets open models answer from today's web rather than their training date. OpenRouter, for example, uses Exa as the default search engine for models that come without built-in search.

Coding agents call Exa to pull working code examples from Exa's code index when they hit an unfamiliar library, and to verify against current documentation, changelogs, and release notes for changes made after the model's training cutoff. Exa Highlights return the relevant excerpt rather than the full documentation page, which keeps tokens per task down. Devin from Cognition and CodeRabbit's code review agents both use Exa; the details are in Exa's coding use case.

No. Exa supplies live web search and page contents through an API, and you keep your own vector store, memory layers, and inference stack. Exa sits beside them as the source for what is on the web today.

Exa Instant, Exa's fastest search tier, returns results in under 250ms. Exa Search also offers Fast at about 450ms, Auto at about one second, and Deep at 4-15 seconds for agentic research, so a provider picks the tier per call. The Exa Instant post has the published figures; for latency on your own stack, talk to Exa sales.

Exa's integrations page lists them by category, including Models & Inference, Frameworks & SDKs, Agents & Assistants, and Automation & No-Code. Exa also connects to Claude, ChatGPT, LangChain, AWS, and Databricks, and runs as an MCP server through Exa MCP.

Yes, without retraining the model. In Exa's published RL study of May 13, 2026, holding the model fixed and changing only the search backend raised SimpleQA Pass@1 from 0.579 to 0.651 on an untrained Qwen3-4B and from 0.689 to 0.730 on an untrained Qwen3-235B. Exa scored higher on 11 of the 12 model and benchmark pairs the study reports. Setup and full tables are in the RL search outcomes post.
