A r/LocalLLaMA post notes that Unsloth’s Gemma 4 QAT MTP assistant models are now available in GGUF format. The root directories include q8_0 files named mtp-gemma-4-*.gguf, while MTP folders contain q8_0 and larger quantized variants. The listed releases cover 12B, 26B-A4B, 31B, E2B, E2B mobile, E4B, and E4B mobile it-qat-GGUF repositories.
A r/LocalLLaMA user is looking for benchmarks comparing Gemma 4 4-bit QAT models, via Unsloth, against standard 8-bit non-QAT quantized models. They understand QAT is expected to preserve much of the BF16 baseline accuracy, but want hard numbers against traditional 8-bit PTQ. The post highlights scattered feedback but no clear head-to-head evaluation yet.
A r/LocalLLaMA user shared quick throughput numbers for Gemma4 QAT with MTP speculative decoding on an RTX 3090 24GB setup. They report roughly 1.2-1.8x TPS improvement, with Gemma 4 31B moving from about 40 tok/s to 70-80 tok/s. The author frames this as a rough benchmark, using 11 task categories and noting stochastic variation from temp 1.0.
