Memory is the weights at that precision plus 20% for the runtime and a short context; a long context needs more. Prices are the lowest on-demand hourly rates in the SAVRN Index, read Sep 18, 2026.

SAVRN's Notes on Qwen3.6-27B-NVFP4

Take Qwen/Qwen3.6-27B, calibrate a four-bit NVFP4 version on a mix of the Unsloth dataset and UltraChat, and you get this checkpoint from Unsloth AI. At 16-bit the model needs 51.0 GB to run; at 4-bit the weights are 10.6 GB and the run needs 12.7 GB, and the publisher states it works on a 24 GB VRAM GPU. Our cheapest listed setup is one MI300X with 192 GB at $1.85 per hour on-demand, which leaves room for the full 262,144 token context.

Apache 2.0 covers commercial use, modification and redistribution, with notices kept and a patent grant. Because this is a quantized derivative, test it against the base Qwen3.6-27B on your own workload; the file carries no reported evaluations. The release was April 23, 2026, updated July 12, and no Index host price exists, so cost is your hourly card rate divided by measured throughput.

Local Inference Lab

WORK IN PROGRESS A mixed NVFP4/MXFP8 quantization-aware distillation of Qwen3.8-27B, trained for one epoch. The student learns from the original BF16 teacher while its MLP weights are quantized in the forward pass. Distillation updates the MLP weights and text normalization weights to account for quantization error. This is a trained distillation checkpoint, not a post-training conversion of the original weights. Attention/GDN projections and the LM head were frozen in their MXFP8 representations during distillation. Packed NVFP4 and MXFP8 weights reconstruct to the same BF16 weight values used by the student during training. The tokenizer, chat template, generation configuration and…
