Our take
Sail Research is a small host serving third-party models, with a prompt-handling story that is partly documented: it does not train on prompts and offers a zero-retention option. Its security attestation and European hosting are unverified in our data, so regulated work needs confirming first.
Use it for cost-sensitive work on DeepSeek V4 Flash, where its rate is the lowest row it lists, or when you need a no-training and zero-retention commitment for prompts you send. Check which offer you are picking on models listed more than once, because the rate differs between rows. Skip it if you need a verified security attestation, confirmed European hosting, or any benchmark evidence for the models it serves.
- Prompt handling is addressed on two fronts — it does not train on prompts and offers a zero-retention option — so sensitive inputs have a stated path rather than an unstated one.
- Its DeepSeek V4 Flash offer is the cheapest row it lists, which makes it the place to start if that model is what you need.
- GLM 5.3 Flash appears at two different rates, so the cheaper row depends on which offer you pick — worth checking before you commit.
- An independent security attestation and European hosting are both unverified in our data, so a regulated or EU-bound workload cannot be confirmed from what we list.
- We hold no benchmark score for any of its offers, so model choice has to rest on your own trial rather than on evidence here.
- Its most expensive offer costs far more than its cheapest, so the bill depends heavily on which model you pick.

We have not recorded what a router needs for Sail Research yet — no base URL and no docs link on file. That is our gap, not a sign Sail Research has no API; its own documentation is the place to look until we close it.
Privacy & data handling
These answers cover requests sent to Sail Research through OpenRouter, as OpenRouter records them, last read 4 hours ago. For Sail Research'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.
