Prompt Caching Slashes LLM Costs by 90% and Boosts Speed
Prompt caching is a technique to reduce costs and latency in LLM applications by reusing computed prompt states. It involves splitting prompts into a stable prefix (system prompt, tool definitions) and a volatile suffix…

Mixture of Experts: Big Models, Cheap Inference Explained
Mixture of Experts (MoE) is a model architecture that allows for a large number of parameters while keeping inference costs low. In MoE, a router network directs each token to a subset of specialized expert networks, ra…

LLM Tokens: How Text is Broken Down and Why It Matters for Cost and Capability
Language models process text by breaking it down into tokens, which are typically chunks of a few characters. This subword tokenization approach is used because using whole words would create an unmanageably large vocab…
