Local inference shootout: Basalt beats Strata at 118 tok/s on Qwen3.8 with half the RAM

Reddit user xMASEx benchmarked two local inference engines, Strata (CLI 0.1.59) and Basalt (0.3.2), on the same model — Qwen3.8-Flash-Next IQ3S with 256k context — on a 12900K / 128GB DDR4 / RTX 5070 Ti box.

Strata: 99.2 tok/s average decode, prefill 839; 15.3GB VRAM but a hefty 69.2GB RAM. Generation stuttered when switching between phases, compaction broke, and tasks often didn't finish.

Basalt: 100–118 tok/s average, peaking at 145; prefill peaks 4200; 15.8GB VRAM and only 53GB RAM. Smooth generation, correct compaction, far fewer errors, and it kept working until the project was done.

The author calls it the first local setup since Qwen-3.6-35B that actually feels reliable, and plans to test nvfp4 quantization next, plus Swift and DeepSeek.
