I'm a huge fan of OpenRouter and their interface for solid LLM's but I recently jumped into fine tuning / modifying my own vision models for FPV drone detection (just for fun) and my daily workstation and it's 2080 just wasn't good enough.

Even in 2025 it's cool how solid a setup dual 3090's still are. nvlink is an absolute must but it's incredibly powerful. I'm able to run the latest Mistral thinking models and relatively powerful yolo based VLM's like the ones RoboFlow is based on.

Curious if anyone else is still using 3090's or has feedback for scaling up to 4-6 3090s.

Thanks everyone ;)
