# Warming (OpenCode V2) Session warming sends periodic model requests to preserve provider-side prompt caches or short-lived state while you pause between prompts. Disabled by default. Enable in config: { "$schema": "https://opencode.ai/config.json", "warming": true } Options: prompt, interval, duration. interval can be "auto" using 90% of model cache.ttl. Timing: starts after non-warming request; warming requests at interval; stops after duration. New activity resets timers. Failures logged without failing session. Costs are real provider requests.
