Fireworks: data residency & retention
Headquarters
🇺🇸 United States (US)
Where inference runs
US, EU, Other
Default serverless is global Fireworks-managed infrastructure with no per-request geography disclosed; dedicated deployments publish ~26 named regions (US, EU Frankfurt/Iceland, Canada, APAC).
Region pinning
Yes, self-serve
Self-serve US-only serverless endpoint (us.api.fireworks.ai, at a price premium) with US-resident models; EU-only serverless is enterprise/contact-sales; dedicated deployments can be pinned by region.
Prompt retention
Not retained
Zero Data Retention by default — prompt and generation data is not logged or stored for open models without explicit opt-in; prompt-cache data lives in volatile memory for minutes; Responses API conversation data auto-deletes after 30 days.
Trains on API data
No
Terms commit: customer content is not used to train Fireworks' own models or to improve the service.
Zero data retention
Available
ZDR is the contractual default for inference (carve-outs: safety screening, Responses API, and training/fine-tuning features).
