WeAreDevelopers LIVE - Vector Similarity Search Patterns for Efficiency and more
What if you could answer questions and route requests without ever calling an LLM? Explore three vector search patterns for building faster, more cost-effective AI applications.
#1about 8 minutes
Getting hired through open source and passion projects
Hear how contributing to open source and sharing your work publicly can lead directly to job opportunities in developer advocacy.
#2about 5 minutes
How critical analysis can accelerate your career
Discover how publicly analyzing and improving upon existing technologies can make you a highly visible and attractive candidate for top companies.
#3about 3 minutes
The hidden costs of large LLM context windows
Understand why simply using larger context windows in models like GPT-5 is not a scalable or cost-effective solution for production applications.
#4about 3 minutes
A quick primer on vectors and vector search
A brief explanation of how text is converted into numerical vectors to represent its semantic meaning, enabling similarity searches.
#5about 9 minutes
Using semantic classification to categorize text
Learn how to use a vector database with reference examples to classify text, avoiding costly LLM calls for simple categorization tasks.
#6about 5 minutes
Implementing semantic routing for tool calling and guardrails
Discover how to use semantic routing to direct user prompts to the correct function or to block inappropriate topics without involving an LLM.
#7about 6 minutes
Reducing latency and cost with semantic caching
Implement semantic caching to store and retrieve answers for semantically similar user questions, drastically reducing redundant LLM calls and improving response time.
#8about 6 minutes
Optimizing accuracy for classification and tool calling
Explore techniques like self-improvement, hybrid fallbacks, and prompt chunking to fine-tune and improve the accuracy of your semantic patterns.
#9about 4 minutes
Advanced caching with specialized embedding models
Learn how to avoid common caching pitfalls, such as misinterpreting negation, by using specialized embedding models trained for semantic caching.
#10about 16 minutes
Q&A on data freshness, persistence, and management
The discussion covers practical considerations like preventing stale cache data with TTL, managing data ownership, and how Redis handles persistence.
