It probably would be called 'deepseek-v4-flash-0731' in API

edit: nope, at least deepseek kept "deepseek-v4-flash" and just updated model underneath. I guess preview is no longer worth serving with that release and you'd have to look through inference provider docs to see if they've updated, yeah..

That's what I mean. On DeepSeek it's now just `deepseek-v4-flash`, while OpenRouter calls it `deepseek/deepseek-v4-flash-0731`, so now when someone talks about DeepSeek V4 Flash, like in benchmarks, or other inference providers, which version do they actually mean?

The `-0731` style suffix is worse compared to a proper version bump like V4.1.

What I and my team have been doing in papers is just to refer to the OpenRouter slugs. It upsets reviewers because they will complain it "is not sufficiently clear to a wider audience" but I do agree it's the cleanest approach. Also goes to prove how much power OpenRouter has actually...

Does it still say that it's an anthropic model, when asked? I would guess new post-training has fixed that.

Does Claude still say it's Deepseek, when asked?

How is that important? Maybe it does, so what?

Not important, just a curiosity. I would expect that kind of knowledge would be pretty well burned into the weights, but what do I know about LLMs. Gemma 4 can answer this question well.

DeepSeek being DeepSeek. v3 and R1 went over the same and had multiple versions

DeepSeek themselves called it `deepseek/deepseek-v4-flash`. Pro is still like that.

Yes that's my point. The old and the new version are different in capabilities, but now when someone talks about DeepSeek V4 Flash (in benchmarks, on inference providers), you don't know which exact version it's about.

Some providers like OpenRouter now call it `deepseek-v4-flash-0731`, but even in places like here on HackerNews people say things like "Sonnet is better than DeepSeek" without specifying a version or a reasoning effort, certainly no one will mention that `-0731` suffix when talking about DeepSeek V4 Flash.

I think it does not matter. Most people who use these types of models are into the IT world, and will know/be informed very fast that there is a difference. People will likely also use the 0731 behind it.

The only issue i see, is 3th party providers that have not yet updated. But that is going to be a short time periode. There is no reason to not update.
