Want to scale AI agents without breaking anything? Retrieval engineering is the answer.
48+ min ago (23+ words) On September 24, GigaOm’s Whit Walters and Vespa.ai’s Bonnie Chase will explain what breaks when hundreds of AI agents hit retrieval at once....
Spark Jobs: Fixing Slow Joins
1+ hour, 27+ min ago (373+ words) Apache Spark job performance issues are frequently caused by improper join strategies leading to excessive data shuffling, rather than suboptimal code. I learned this lesson the hard way. We had a critical data pipeline running for over 3 hours every single…...
IT firms explore model routing to manage cost and complexity
1+ hour, 24+ min ago (349+ words) With rapid advances in open weight models and growing concerns over AI costs, a new paradigm is emerging in enterprise AI deployments - model routing. IT companies are increasingly experimenting with an extra orchestration layer that mix cutting edge frontier models…...
Your monitoring says healthy. Your agents are not.
1+ hour, 21+ min ago (378+ words) In the weeks leading up to our most recent production run, our local LLM agent fleet experienced a series of failures that went unnoticed for days. Looking at the failure ledger, several patterns emerge: These failures indicate that while the…...
My RTX 3060 Can Run Many LLMs — Just Not at the Same Time
1+ hour, 26+ min ago (442+ words) Running a local LLM is easy. Running multiple specialized models for coding, reasoning and AI agents on a 12GB GPU is where things get interesting. My local AI machine is fairly ordinary: Modern 7B–12B models run surprisingly well on this hardware. But…...
Neural networks reveal how training shapes learning in living brains
1+ hour, 45+ min ago (533+ words) A new study has used a type of machine learning called a neural network to reveal how different kinds of training can change how learning happens-both in machines, and in living brains. We can use these complex models to make…...
NVIDIA DGX Spark vs. Mac Studio M5 Ultra: Which One Should You Actually Buy to Run AI Locally?
2+ hour, 5+ min ago (1078+ words) NVIDIA DGX Spark: $4,699. 128GB of memory, shared between the CPU and GPU. Memory bandwidth of about 273GB/s. It has been shipping and available to buy since late 2025. Mac Studio (M5 Ultra, 36-core CPU / 80-core GPU, 256GB): $10,799. 256GB of memory. Memory bandwidth of about 1.2TB/s (roughly…...
