How To Overcome Context Limits in Large Language Models
Understanding the Challenge of Context Limits in LLMs
Ever wondered how to overcome context limits in LLMs? Large Language Models (LLMs) are powerful tools for processing and understanding vast amounts of text. However, they come with a challenge - context limits.
These limits restrict the amount of data that can be processed at once, often leading to errors when the limit is exceeded.
The Impact of Context Limits on Data Processing
Context limits can significantly impact data processing. For instance, if you're trying to process a 42MB PDF file with over 160 pages of dense documentation, you'll likely encounter a context error. This is because the context limit of most LLMs, like GPT 3.5, is around 4000 tokens, which is approximately 2000 words. So, how do we bypass these LLMs context limits?
The Power of Vector Embeddings and Vector Search
Breaking down text into manageable chunks is one effective way to overcome context limits in LLMs is by using vector embeddings and vector search. For additional insights, we've crafted a detailed blog post on how to generate Open AI embeddings with your data.
This technique involves breaking down the text into manageable chunks, each containing a specific number of tokens. For instance, you can split a large text into chunks of 500 tokens each.
Once the text is broken down into chunks, you can then use vector search to retrieve the most relevant pieces of information to a specific input query. This process basically works as a semantic cache for the LLM, involving embedding each chunk of data and sorting them using cosine similarity to detect the closest match to the search query.
Enhancing Accuracy and Efficiency in LLMs
Adjust context window and chunk sizes. To improve accuracy, you can adjust the context window and chunk sizes.
For instance, instead of using six pages, you might want to increase it to 10 or 20 pages. This increases the chance of the chunk containing the information you want, thereby helping you bypass LLMs context limits more effectively.
Step-by-step Guide to Bypassing LLMs Context Limits
Ready to put this into practice? Here's a step-by-step guide to help you overcome context limits in LLMs:
1. Break down the text into manageable chunks.
2. Use vector search to retrieve the most relevant pieces of information.
3. Adjust the context window and chunk sizes to improve accuracy.
4. Leverage larger models for greater context limits.
Real-world Application: Processing Large PDFs with LLMs
This technique is not just theoretical; it has real-world applications. For instance, you can use it to process large PDFs with LLMs, transforming them into text and retrieving relevant information based on specific queries.
Next Steps: Optimizing Your Use of LLMs
While vector embeddings and search are effective, there are other techniques you can explore to overcome context limits in LLMs. For instance, you can use the map reduce technique, which involves summarizing each chunk of data into a smaller chunk and processing those summaries instead of the full page.
Leveraging Larger Models for Greater Context Limits
Another way to overcome context limits in LLMs is by leveraging larger models. For instance, if you're using GPT 3.5 and you've hit a limit of 4000 tokens, you might choose to move to the 3.5 16K model. This increases the context limit by four times, allowing you to process larger amounts of data.
