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...
