Every token, everywhere, all at once — idlemachines Every model that turns a variable-length collection of vectors into one vector is making a choice about what to throw away. Pooling methods are a spectrum, and frontier embedding models live at specific points on it.
Visibility Into the Black Box I ship production code through an AI pipeline. Not to a toy project — to a ten-year-old Rails monolith that serves real users, reviewed by teammates who genuinely care about craft. They love OOP. They spot code smells three abstractions deep. They'll tell...

Tokenization Is the Bottleneck You’re Not Measuring You’ve optimized your GPU serving stack. You’ve tuned vLLM’s batch size, configured PagedAttention, maybe even set up prefix-aware routing for KV cache locality. Your P99 looks good. Your throughput is climbing. And somewhere in your proxy layer, every si...
