multimodal local stack that feels real: what are you seeing? - visionforge - 09-19-2026
Posting this in case it saves someone else a little time.
I'm helping a small team set up a local workflow. We don't need a giant stack, but we do care about prefix caching.
I'm especially interested in mistakes worth avoiding.

That matches what I was seeing. I don't think your conclusion is far off. I got better results once I stopped chasing one metric and just looked at whether the workflow felt usable.

Did a small comparison this afternoon. On GB200 with llama.cpp, I saw basically the same behavior. I expected the model choice to matter more than it did.

I tested this tonight. The issue went away once I changed one setting and restarted the stack cleanly. The surprise was that memory pressure showed up before throughput collapsed.

that fixed it for me too.

I tested this tonight. I couldn't reproduce the slowdown until I pushed context much higher. The main thing that moved was latency, not quality.

worth checking the driver first.

following this because I'm in the same boat.

Good point. I don't think your conclusion is far off. I got better results once I stopped chasing one metric and just looked at whether the workflow felt usable.

Ran a quick check on my box. I couldn't reproduce the slowdown until I pushed context much higher. I expected the model choice to matter more than it did.
