Brave Summarizer takes on Bing and ChatGPT at the AI search results game

Hopping on the AI train, Brave is incorporating its own AI-powered search function to its web browser called Summarizer – similar to what Microsoft recently did to Bing.

The new feature “provides concise and to-the-point answers at the top of Brave Search results”. For example, if you want to learn about the chemical spill in East Palestine, Ohio, Summarizer will create a one paragraph summary of the event alongside some sources for you to read. Unlike Microsoft which only uses ChatGPT for Bing's chatbot, Summarizer uses three in-house large language models, LLMs for short, based on retrained versions of the BART and DeBERTa AI models to create the search-results snippets.

Retraining AI

To simplify the technology behind them, BART and DeBERTa are generative writing AIs like ChatGPT that have been specially trained to take into account word positioning as well as context so the text output reads well. What Brave did is take those models and retrain them using its own search result data to develop Summarizer.

Summarizer’s training regiment is a three-step process, according to the announcement. First, Brave taught the LLMs to prioritize answering the question being asked. Then, the company utilized “zero-shot classifiers” to categorize results so the given information is relevant. The final step helps the models rewrite the snippet so it’s more coherent. The result is an accurate answer written succinctly with multiple sources attached.

Be aware the feature is still in the early stages. Brave states Summarizer only utilizes about 17 percent of search queries to formulate an answer, but there are plans to scale that number even higher for better paragraphs. Its accuracy needs some work, too. The company admits Summarizer may produce what it calls “hallucinations” which are unrelated snippets mixed in with results. Plus there's the possibility of the feature throwing in some “false or offensive text” into an answer.

Availability

Summarizer is currently available to all Brave Search users on desktop and mobile with the exception of the Brave Search Goggles. It’s disabled there. You can turn it off anytime you want by going into the browser’s settings menu. The company is also asking users to give some feedback on how it can improve the tool. 

We tried out Summarizer ourselves, and as cool as it is, it does need some work. Not all search results will give you a snippet as it depends on what you ask, as well as which news topics are making the rounds. The East Palestine, Ohio chemical spill, for example, is currently a hot button issue so you get Summarizer working just fine there. However when we asked about the recent cold snap in Los Angeles and what’s going on with certain video game developers, we either got no summary or outdated information. But the latter did come with sources so it was at least accurate. Still better than having ChatGPT throw a temper tantrum or lie to your face.
