Reading on inference

• Choosing an inference runtimeThe wrong runtime costs you throughput you never knew you were leaving on the table. The right one is usually decided by traffic shape, not model size.
• Context is a budget, not a containerThe instinct is to keep everything in case it is needed. The models are not filing systems, and past a certain length the middle of your context is doing nothing but costing money.
• Choosing a model is a routing problemThere is no best model. There is a best model for a task, at a quality bar, within a latency and cost budget — and that decision is a routing policy, not a benchmark.
