Scaling to 11M Embeddings: Product Quantization Success
Read Full Article: Scaling to 11M Embeddings: Product Quantization Success
Handling 11 million embeddings in a large-scale knowledge graph project presented significant challenges in terms of storage, cost, and performance. The Gemini-embeddings-001 model was chosen for its strong semantic representations, but its high dimensionality led to substantial storage requirements. Storing these embeddings in Neo4j resulted in a prohibitive monthly cost of $32,500 due to the high memory footprint. To address this, Product Quantization (PQ), specifically PQ64, was implemented, reducing storage needs by approximately 192 times, bringing the total storage requirement to just 0.704 GB. While there are concerns about retrieval accuracy with such compression, PQ64 maintained a recall@10 of 0.92, with options like PQ128 available for even higher accuracy. This matters because it demonstrates a scalable and cost-effective approach to managing large-scale vector data without significantly compromising performance.

Puppeteer MCP: Hidden Agent Confusion
Read Full Article: Puppeteer MCP: Hidden Agent Confusion
Testing the Puppeteer MCP server initially seemed successful, as connections were established and tools appeared without errors. However, once the agent began operating, issues emerged with actions like clicks appearing to work but not being recognized downstream, leading to repeated steps. The root cause was traced to Puppeteer tools not clearly declaring their returns and relying on vague parameters or implicit contexts, causing silent confusion for agents. This highlights the importance of thorough validation of MCP servers before runtime to prevent such issues, as demonstrated using a tool called Syrin for analysis. Understanding these nuances is crucial for ensuring seamless automation processes and preventing hidden operational failures.
