Long context on this hardware · up to 1M tokens
Largest context whose KV cache still fits next to the weights (same placement as the 16k result, KV types f16 / q8_0 / q4_0). Models are capped at their verified maximum; extended means beyond the native maximum using YaRN, only listed where the model card documents it. Long context needs flash attention (-fa on, already in the commands) and a lot of memory; a quantized KV cache saves memory but can cost accuracy. Speed at depth is an estimate (penalty fitted to measured depth runs up to 128k).

Speeds marked measured are medians of real runs (short-context generation) from these sources; scaled from measured means a measurement of a same-size or same-model-different-quant run, scaled by bytes read; estimated comes from memory bandwidth (spec source: https://www.techpowerup.com/gpu-specs/geforce-rtx-5070.c4218) × an efficiency factor of 0.78 calibrated to measured runs on this hardware. 11 measured data points on file for this hardware · submit your benchmark. System RAM here is an example (32 GB, ddr5-5600). Model data last verified 2026-10-14. Ranking = fits and fast enough first, then larger; not a quality benchmark.
