they only charge you 10% tokens for compute they already did.
so if you're sending lots of repeat context you REALLY want cache control
https://platform.claude.com/docs/en/build-with-claude/prompt-caching
according to my guy, openclaw is hardcoded to only pass the cache information if the provider is set to Openrouter
or you're using Anthropic directly
which is a drag because nanogpt and others are configured to handle it.
