How Prompt Caching Can Cut LLM API Spend by 40%
Identical system prompts resent on every request are wasted spend. Learn how edge caching and Tokened Gateway solve this.
The duplication problem
Most chat apps send the full system prompt on every message. If your system prompt is 800 tokens and you handle 100k messages per day, you are paying for 80 million duplicate tokens daily — only the last user message actually changed.
Cache at the edge
Tokened Gateway (beta) deduplicates identical prompt prefixes at the proxy layer. Point OPENAI_BASE_URL to api.tokened.uk and identical requests hit cache before reaching the provider.
For read-heavy workloads (support bots, documentation Q&A), teams typically see 25–40% cost reduction in early tests.
