To add to this, Fireworks (and many competitors, e.g. enumerated here[0]) offer zero-data retention inference, to anyone. DeepSeek cloud does not. It's part of their terms that anything you send them is fair game for them to train models on.

It’s pretty clear despite what they want you to think Anthropic and OpenAI train on everyone’s data who has a subsidized plan. Only way you get ZDR is by paying API prices. Also note that it is zero retention, not zero training.

> "Also note that it is zero retention, not zero training"

The "green" badges explicitly say the opposite:

> "Private: this provider does not train on prompts and does not retain prompt data."

I.e. for the example of Fireworks, this is the precise language they use to describe ZDR:

> "More technically: prompt and generation data exist only in volatile memory for the duration of the request. If prompt caching is active, some prompt data (and associated KV caches) can be stored in volatile memory for several minutes. In either case, prompt and generation data are not logged into any persistent storage."

How is it clear? I don't fully trust them either, but what indications are there?

Spoiler, it's not clear by any means. There's no evidence to back up the claim, it's just their feelings... which is fine, but I definitely wouldn't call it clear.

My slight suspicion is that the that somehow train on derived data from the sessions. In a way that they are technically in the clear.
