That's because Qwen's flagship models are not, in fact, open weight. Qwen3.7 Max, Qwen3.7 Plus and others are closed weight.

You can use Qwen3.6 35B A3B (for example) on Openrouter with a US-based ZDR provider, because it's one of their open weight models

They changed course when they fired the old lead and hired a new 1 from ex-gemini.

No, Qwen Max series has always been proprietary.

They also stopped releasing 100b+ model weights after firing him

Unless you self host, zero data retention cannot be guaranteed.

apples private cloud compute can get close, its still not 100 safe because backdoors and crypto breaks are possible but you go from trusting the data center operator with all their employees to only the person thats inspecting new hardware and giving out certificates (apple in this case). if some well known non profit like mozilla or isrg starts doing it with full open source software its like the best possible security

The handy thing about trusting Apple here is: you already were trusting Apple. I don't necessarily like that trust works this way, but that's just the physics of it.

That is completely obvious, it’s like saying “100% security does not exist”.

I believe you are falling into the nirvana fallacy: No shades of grey, if it’s not perfect it’s as bad as the rest.

This is a very inefficient way of thinking as it is not possible to self host everything for most people, it just demands too much time.

Hence its is a perfectly valid approach in my opinion to looks at better (or, very often, “less worse”) SaaS solution.

If they states ZDR on a model, the likeliness of it leaking less data to some LLM data training is higher simply. If the business model of a company is built around a differentiator which is data privacy, that also significantly increases probability that data is not being leaked/sold.

It’s all grey, relative and about probabilities. Nothing’s perfect – another captain obvious thing.

Yeah but how much higher chances ? Could be ver low

Just like most things in life the guarantee it based on the entity/person providing said guarantee.

I can host a LLM in my basement and guarantee it, but would you trust me? Now you can say that you don't trust any company, but B2B relies on counterparty risk.

Confidential inference gets us closer
