Release notes
Cheaper cloud turns with real cache accounting
Cloud requests keep a stable prompt prefix so providers can reuse it, context usage shows cache writes, and cost estimates bill those writes at the provider rate.
Fixed
- Cloud turns no longer put volatile context into the cached system prefix, so later steps can reuse the prompt cache.
- Cloud models keep the full tool schema by default instead of shrinking it every step.
- Context cost estimates include cache-write tokens instead of billing them as fresh input.
New
- Context usage shows cache-write tokens when the provider reports them.
- Cloud requests send a prompt-cache key for the run so later steps can hit the same cache.
