Our take
Ionstream is a small host for downloadable models where the prompt-handling terms are the point: it does not train on prompts and offers a zero-retention option. Its three offers are all models you can get elsewhere, so nothing here is exclusive.
Use it when prompt handling is the deciding factor on DeepSeek V4 Flash, DeepSeek V4 Pro or Qwen3 8 27B, and you want those terms rather than the lowest rate. Its own offers differ on input cost, so check which one you need before committing. Skip it if you need a verified security attestation or a confirmed European endpoint, or if you want measured speed or quality figures to choose between models.
- It does not train on prompts and offers a zero-retention option, so prompt handling is the reason to pick it over a host with no such terms.
- Among its own three offers, Qwen3 8 27B carries the lowest input rate, which makes it the cheaper starting point if you are testing the terms.
- Headquarters country, a European endpoint and an independent security attestation are all unverified in our data, so a regulated or EU-resident workload cannot be confirmed from what we list.
- No benchmark score or throughput figure is recorded for any of its three offers, so the choice rests on price and terms alone.

Privacy & data handling
These answers cover requests sent to Ionstream through OpenRouter, as OpenRouter records them, last read 58 min ago. For Ionstream's own API we hold no answer: check its terms. SOC 2 and the data processing agreement below are hand-checked, not part of that sync.
Prompt retention: none.
