tok/s token generation, batch 1, per-request, ctx 128k
Model
gpt-oss 20B
Methodology
Hardware Corner per-GPU context-tier table (March 2026 update), single RTX 4070 Ti SUPER, llama.cpp GGUF, batch-1 per-request. gpt-oss 20B MXFP4, context depth 128k. Prefill column is prompt-processing tok/s; generation column is decode tok/s. NOT an aggregate across concurrent requests. The page does not reprint the llama-bench build hash (the site's sibling ranking page pins CUDA 12.8 / Q4_K_XL).

third_party
Reproducible
yes
notes
Paired prefill is 993.5 tok/s in the same table cell. Per-request, not aggregate.
