Thought I'd post a small recipe because a lot of threads ask similar things.

Maybe useful as a starting point: MLX on GB200, keeping HBM constraints in mind from the start.

If someone wants the exact settings I can clean them up and post them.

My use case is pretty ordinary: local chat, some document work, and occasional batch jobs.

Wanted to compare notes with people doing similar things.

I'm trying to decide whether to keep the current stack or change course. Main question is how people here are handling router policy.

Would appreciate practical advice rather than theory.

Did a bit of testing and thought I'd post the result here.

I tried this with FLUX using vLLM on GB200. The headline result was better than I expected, but router policy still ended up being the limiting factor.

Curious if anyone else landed in the same place.

Short version: PyTorch behaved well for me, but only after I stopped ignoring NVFP4.

Happy to post more details if anyone wants them.

I tried this with Phi using LM Studio on B200. The headline result was better than I expected, but batch size still ended up being the limiting factor.

Curious if anyone else landed in the same place.

I care more about stability than squeezing the last possible tokens/sec out of it.

Posting this in case it saves someone else a little time.

I'm not trying to build a perfect architecture diagram. I just want a sane starting point around LM Studio and 5090.

Would rather learn from your scars than collect my own all at once.

I'm trying to sanity-check my setup.

My current setup is TensorRT-LLM with B200, and I keep running into prefix caching.

Would appreciate practical advice rather than theory.

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

One thing I keep noticing is that people underestimate NVFP4 until they actually try to run this stuff for more than one afternoon.

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

I'm helping a small team set up a local workflow. We don't need a giant stack, but we do care about MoE serving.

I'm especially interested in mistakes worth avoiding.

This is mostly for local work rather than public serving.

Maybe useful as a starting point: MLX on 5090, keeping tail latency in mind from the start.

Feel free to tear it apart if you see something dumb.

For context, I'm not chasing leaderboard numbers. I mostly want the system to feel consistent day to day.
