Better prompt caching for GPT-6
How-To How to actually use this
What changed: GPT-6 improves prompt caching with higher cache hit rates, new diagnostics, explicit breakpoints, and cost/latency controls.
How to use it:
- Enable prompt caching in your API call parameters to let GPT-6 reuse previous prompt segments.
- Monitor cache hit rates using the new diagnostics endpoint to verify caching is working.
- Set explicit breakpoints in long prompts to control which segments get cached and reused.
- Adjust latency and cost controls to balance caching aggressiveness against response time and budget.
Good for: developers optimizing API costs and latency with repeated prompts
