EXA uses Langgraph to innovate with a multi -agent web research system.

EXA, a prominent player in the Search API industry, has unveiled its sophisticated multi -agent web research system, the latest innovation. According to Langchain, this development is driven by Langgraph and Langsmith and aims to revolutionize how complex research queries are processed.

Evolution to agent search

The journey of EXA to this advanced system began with a simple search API. Over time, the company has evolved its products to include the end of the answer that integrates the Large Language Model (LLM) reasoning with the search results. The latest development is their deep research agent and enters the true agent search API. This reflects the wider industrial trend for more autonomous and long -term LLM applications.

The transition to a deep research architecture has made EXA adopted a Langgraph, which has become a framework that is preferred for processing more and more complex architectures. This change is consistent with the industrial movement where simpler settings are upgraded to handle more sophisticated tasks such as research and coding.

Multi -agent system design

EXA’s system features a multi -agent architecture created in Langgraph, which is configured.

1. plannerAnalyze the query and create parallel tasks.
2. work: Executing independent research using professional tools.
3. observer: Maintain context and quotation and supervise the entire process.

This architecture allows dynamic scaling to adjust the number of work according to the complexity of the query. Each work provides specific guidelines, necessary output formats, and API tools of EXA to ensure efficient processing with simple queries.

Major design insights

EXA’s system emphasizes structured output and efficient use of resources. Prioritizing the inference in the search Snipet before searching the entire content, the system reduces token usage while maintaining research quality. This approach is essential for API consumption, which is reliable and structured.

EXA’s design selection gains inspiration from other industry leaders, such as the in -depth research system that integrates the best practices to context engineering and structured data outputs.

Use Langsmith for the possibility of observation

It played an important role in the development of EXA’s system in Langsmith’s observation function, especially token use. This feature provided essential insights to resource consumption, provided information to price models and optimized performance.

EXA’s software engineers, Mark Pekala, emphasized the importance of contributing to understanding the use of the central token with the ease of setting LANGSMITH and the cost -effective scalability of the system.

conclusion

The innovative use of EXA’s LANGGRAPH and LANGSMITH shows the potential of a multi -agent system when efficiently processing complex web research queries. This project emphasizes major takeouts of similar efforts, such as the possibility of observation, reuse, structured output and dynamic work.

As EXA continues to improve its deep research agents, this development serves as a model for building a powerful production preparation agency system that provides significant business value.
