Great Language Models (LLS) have made significant improvements to use the skills of thinking. However, the ability to properly refer and use foreign data – non-taught information – left behind with justification.

Especially LLMS dynamics is an issue when using intensive scenarios that require the most modern information from search engines.

But a development came: Search-R1, presented a technique a piece of paper Researchers at the University of Illinois are based on Urbana-Champaign and Massachusetts University Amherst, search engine search engine searches.

Enterprises looking for ways to integrate these new models in apps, use techniques such as search-R1 promise to open new thinking abilities.

The problem of search integration with llms

Search engines are important to provide LLM applications with modern, foreign knowledge. Are two main methods to combine search engines with llms Returned generation (Dwarf) and tool usage, emergency engineering or Model Beautiful Adjustment.

However, both methods have no constraints that do not match models. The punishment is often struggling with the inaccuracies that often fights and is important for the way of thinking, there is no opportunity to fulfill multiple survey regimes.

The use of a training-based vehicle, often combat generalization, training-based approaches, requires a wide range of search and meditation-thinking interactions, which are difficult to produce a scale.

(In our own Experiments with practice modelsIn addition, we have seen the data received as one of the main problems.)

Search-R1

Search-R1, LLMS allows you to interact with search engines particle the process of thinking like the presence of a separate search phase.

Search-R1 sets the search engine as part of the LLM environment, allows the model to combine its significant generation without problems with the search engine.

Researchers have designed search-R1 to support iterative substantiation and search. Model is designed to create a set of separate tokens for thinking, search, information and response segments. This means that during the reasoning process (marked) Tags), if the model determines that it needs foreign data, a sequence that contains the search query. The survey then moved to a search engine and the results are included in a context window segment. The model then justifies the reason in addition context and when ready segment.

This structure model allows you to call the search engine several times several times with the reasons for the problem (see example below).

Learning reinforcement

It is difficult to connect with search queries with teaching LLMS, chain of mind. To simplify the process, researchers have prepared a search-R1 to develop a clean reinforcement learning (RL) to explore the use of guidance and use of search tools from man’s information.

Search-R1 uses the model “from the result based on the result based” based on the correctness of the final answer. This eliminates the need to create complex premium models confirming the production process of the model.

This is the case The same approach used in DeepSEek-R1-ZeroThe model is given a task and only judged by the result. The use of Pure RL eliminates the need to create a large database of manual-written samples (delicate arrangements).

“As an extension of the search-R1, DeepSeek-R1, primarily explains the search-expanded RL training for advanced search decision-making,” they wrote in researchers’ paper. “

Search-R1 in the activity

Researchers tried the search-R1 by delicate the base and showed versions Qwen-2.5 and Llama-3.2 Appreciate them in seven criteria covering various substantiated tasks that require single turning and multi-hop search. They compared the search-R1 against different bases: with a direct result Philosophy (Cot) Fine arrangement for justification, dwarf, imagination and tool.

Search-R1 consistently removes key methods in a row. Also, trained in RL, but in search mode exercises. “It adapts with expectations, as included in the search for the justification of the LLM, improving the overall performance, improving the overall performance,” researchers write.

The search-R1 also offers also effective for both basic and training-training options for both basic and training-training options, the result can be useful outside RL’s pure justification scenarios. Researchers released Code for search-r1 In GitHub.

Search-R1’s autonomous can have a significant impact on enterprise applications to create search queries and justify real-time information. In areas such as customer support, knowledge management and data analysis, LLM can increase the accuracy and reliability of managing systems. By enabling LLMS to connect to variable data, search-R1 can help establish smarter and responding AI solutions. This ability can be very useful for applications that require access to constantly changing data and require more than one step to find the answer.

In addition, the new reinforcement learning paradiginal has not yet been investigated since the release of DeepSee-R1.
