Are y'all doing commission-only videos?

Hello! I run a small Youtube channel about game development (7k subscribers). I realize that I'm not at the point where brands may want to sponsor my videos, BUT I am getting quite a few companies (mostly AI companies) reaching out to me wanting me to review their products in exchange for commission-only work. I even had a brand request a 10 min. long video for only commission? That seems a little wild to me, but wanted to know mostly how common is this? Is this a viable source of income for anyone? Is it even worth it to try and negotiate with these brands? Thank you in advance!
