How do people in industry benchmark models?

Hi guys!

So recently as a learning exercise I tuned a Qwen3 model for coding task. I was now interested in understanding how to properly benchmark these tunes models using wellknown benchmarks. But, I'm a bit unsure about how this is exactly done, and was curious about how this is typically done in the industry.

Do each of these big tech companies usually have their own internal benchmarking frameworks/strategies? Or are there popular tools or frameworks that are widely used across both the community and in industry? Since I'm a bit new to the field would like to know what you guys think, what you've used and seen during your learning, etc. Thanks a lot!! :))
