ChatGPT took the world by storm since its release in November 2022, amassing over 1 million users within 5 days according to Techcrunch. 

However, its impressive conversational abilities rely solely on its 175 billion parameter model without any external memory storage. 

By utilizing a retrieval plugin, ChatGPT overcomes the limitation of solely relying on the information provided during the current conversation. This can lead to inconsistent responses over time as ChatGPT's activations fade. 

To enhance long-term memory, Anthropic has announced a new retrieval plugin that connects ChatGPT to a 750GB datastore of webpages, books, and other textual information. 

Early benchmarks show that this plugin improves consistency by over 60% while increasing response accuracy. Sources indicate this is only version one, with plans to incrementally improve the retrieval plugin and datastore. 

This article will better explain the ChatGPT retrieval plugin in detail!

What is a ChatGPT Retrieval Plugin?

ChatGPT was originally trained only on text available up until 2021, meaning its knowledge was cut off after that date. This can cause inconsistent or inaccurate responses when asked about recent or unfolding events. 

To supplement ChatGPT's limited memory, Anthropic has developed a retrieval module plugin that connects it to a curated datastore of webpages, books, and other text sources. This provides "readonly" access to facts spanning different time periods.  

Technically, the retrieval module works by indexing relevant pages and text excerpts into vector embeddings that encode their semantic meaning. When ChatGPT generates a response to a user prompt, the retrieval module searches the index for related vector embeddings to find supplementary evidence passages to enhance the response. Relevant excerpts are then blended into ChatGPT's answer. This allows ChatGPT to effectively augment its knowledge with up-to-date information pulled dynamically from the latest additions to the datastore.

Sources span news articles, reference material, books, case law, scientific publications, and other reputable sites. As the company states, the goal is to make the datastore "as useful, harmless, and inoffensive as possible" through careful curation guidelines.

With rigorous filtering and monitoring, the retrieval functionality could allow language models to incorporate a read-only "summary of the world's knowledge" far surpassing their training datasets. Responsible design will be critical as these models become increasingly augmented by external sources.

How does a ChatGPT retrieval plugin enhance the capabilities of ChatGPT?

The plugin leverages a long-term memory store to access a broader range of knowledge and context. This enhances ChatGPT's capacity to provide more accurate and contextually appropriate responses.

ChatGPT can refer back to past conversations, recall relevant information, and maintain continuity in discussions. The retrieval plugin ensures that ChatGPT taps into its long-term memory effectively, giving it an edge in understanding and engaging in more meaningful conversations.
