Goodput, Not Throughput: The Metric That Decides Whether Your LLM Deployment Works

Two servers run the same model on the same GPUs. One reports 4,200 tokens per second and is unusable; the other reports 2,600 and feels instant. Throughput is a property of the server, latency is a property of the request, and th…

Prompt caching is not just a cost optimisation - it changes what apps you can build

Most teams treat prompt caching as a billing hack. The deeper consequence is that you can now ship product patterns - persistent agents, large-context tools, system-prompt-heavy UX - that were latency-prohibitive eighteen months ago.

Sleep-Time Compute: Thinking About the Context Before the Question Arrives

Test-time compute makes models smarter but slower and pricier. Sleep-time compute moves the thinking to before the user asks, cutting the compute needed for the same accuracy by roughly 5x and the cost per query by 2.5x when cont…

Speculative Decoding: How a Small Draft Model Makes Large Language Models Think Faster

Autoregressive decoding forces even the largest language models to emit one token at a time, bottlenecked by memory bandwidth rather than compute. Speculative decoding breaks this sequential constraint by letting a lightweight dr…
