What kind of tests should I run?

Also, what does "initial" support mean...that certain features aren't supported or it's a work in progress?

text versions should (except MoE) should be supported. The PR pick up the name from the fist commit.

Regarding the test to runs, since you asked for support(Qwen3 support please?? #1902) I was under the impression that you had a use case for it. If this is not the case, test it following the instructions and try a few prompts can be indeed helpful.

Definitely, just wondering if any particular tests would be useful for you guys and ctranslate2 development in general. I generally test on a variety of prompts and get a rough vram usage and speed measurements, but it's not flawless benchmarking like some professionals.
