clean API wrappers for local agents for FLUX

This keeps coming up in conversation so I figured I'd start a thread.

The more I work with local setups, the more it seems like MoE serving decides everything downstream.

Curious whether that lines up with what other people are seeing.

A couple things I'd check first. If you're on TensorRT-LLM, I'd confirm the version first and then reduce variables until the behavior is obvious. A lot of these threads end up being one bad config plus a pile of conclusions drawn from it. At this point the real bottleneck is my patience.
