The guide emphasizes starting small with well-scoped problems, focusing on core LLM reasoning tasks first, and treating deployment as the beginning of iteration rather than the end of development. 163 2. 2 [](https://daily.dev/posts/open-deep-research-rusxtzcwn "Open Deep Research") Article LangChain · 1y Open Deep Research LangChain introduces an open-source deep research agent built on LangGraph that automates comprehensive research tasks. The system uses a three-phase approach: scoping (clarifying user requirements), research (using supervisor and sub-agents for parallel investigation), and writing (generating final reports). Key insights include using multi-agent architecture only for parallelizable tasks, isolating context across research topics to avoid token bloat, and implementing context engineering to manage computational costs. The agent flexibly adapts research strategies based on request complexity and is available through LangGraph Studio and Open Agent Platform. 22 [See all LangChain archives](/sources/langchain/best-of) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@graph":[{"@type":"CollectionPage","@id":"https://daily.dev/sources/langchain/best-of/2025/07#page","url":"https://daily.dev/sources/langchain/best-of/2025/07","name":"Best LangChain Posts — July 2025","description":"The most upvoted LangChain posts from July 2025, curated by the daily.dev community.","isPartOf":{"@type":"WebSite","url":"https://daily.dev"}},{"@type":"ItemList","@id":"https://daily.dev/sources/langchain/best-of/2025/07#items","numberOfItems":2,"itemListElement":[{"@type":"ListItem","position":1,"url":"https://daily.dev/posts/how-to-build-an-agent-nar2dga30","name":"How to Build an Agent"},{"@type":"ListItem","position":2,"url":"https://daily.dev/posts/open-deep-research-rusxtzcwn","name":"Open Deep Research"}]},{"@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Sources","item":"https://daily.dev/sources"},{"@type":"ListItem","position":3,"name":"LangChain","item":"https://daily.dev/sources/langchain"},{"@type":"ListItem","position":4,"name":"Best of","item":"https://daily.dev/sources/langchain/best-of"},{"@type":"ListItem","position":5,"name":"July 2025"}]}]} ```
