I...don't follow. How in the world does your comment about open weight and open source relate? Ignoring that it has nothing to do with this post (did you mean to reply to someone), are you aware that Anthropic, OpenAI and others allow 3rd party inference providers to run their proprietary models? Like, what does this non-sequitur even mean?

You understand Moonshot AI could have had other parties run inference for them without releasing the weights, right? These two points are utterly unrelated, unless you think Fable and GPT5-6 are also "open weight" because other providers are providing inference?

Further, having access to the source material in no universe allows you to know what a model is "capable of". I'm not sure how this follows.
