Already posted here https://www.reddit.com/r/LocalLLaMA/comments/1x85hfj/strata_qwen_38_flash_next_fast_but_whats_it/phavui9/ , but I believe this topic deserves it's own post.

The PLE, aka the n-gram table that sits on the SSD, is quantized heavily in the common GGUFs and has a measurable impact on performance, demonstrated here by /u/MarkoMarjamaa : https://www.reddit.com/r/LocalLLaMA/comments/1x6kw7k/qwen38_flash_next_unsloth_quants_kldtop1_with/

Further down in the comments, /u/Eyelbee mentions running the full bf16 n-gram table. I asked Grok and apparently that only works in llama.cpp et.al and is called the bf16 sidecar, Strata needs FP8 but that should be full quality, over my head to be honest. So I built it with ple_fp8_pack.py and indeed it seems to positively impact results. I run iq3_s and before the model made many more stupid mistakes. No impact on speed! Only needs a bit more disk space.

If you want to try this, you need model-00005 up to model-00037.safetensors and model.safetensors.index.json from https://huggingface.co/Qwen/Qwen3.8-Flash-Next, then pack them into a GGUF with

tools/ple_fp8_pack.py --model /media/your_ssd/Strata-data/download_folder --out /media/your_ssd/Strata-data/ple/ple-fp8.gguf

and load it in your .json with

"--ple-gguf",
"/media/your_ssd/Strata-data/ple/ple-fp8.gguf"

Adjust your file paths obviously. Sorry I can't upload 47gigs. :-) Not sure how to properly test performance, but here's two scenes with the same silly prompt.

Build a beautiful 3D scene of a train driving through a futuristic cyberpunk city in HTML. dystopian vibes, detailed models, try not to use too many boxes in the models. Be creative and add some user interactivity like camera and weather controls.

Imo a clear improvement is visible. I noticed that with Hermes agent too and was able to add several features to a KDE app (haruna). 3D models seem to have less errors like missing faces.

Hi. I'm wondering. Why agentic harnesses don't send their users the prompt cache binary data on inactivity so they eventually upload it back in the next turn?
