Product updates Prompt Caching is GA on DigitalOcean Serverless Inference: Up to 90% Off the Context Your Agents Resend By DigitalOcean Updated: October 23, 2026 4 min read <- Back to blog home Prompt caching is now generally available on DigitalOcean Serverless Inference, across supported models in our open model catalog, with no changes to your request code required. Cached input is billed at up to 90% off and time to first token drops by up to 80%.* An agent never starts over. Each new call adds the result of its last tool call to the end of a context that already holds the system prompt, the tool definitions, every file it has read, and every earlier action and result. On DigitalOcean Serverless Inference, more than 90% of the input tokens that agents send are tokens the model has already processed. Prompt caching cuts the cost of those tokens by up to 90% depending on the model, but only when the request reaches the replica holding the cache.
