gpt-oss:20b on other hardware

Reproduce this run

toolOllama 0.21.0
modelgpt-oss:20b (MXFP4)
context8,192
clientv0.4.20+97

Set those in Ollama, then:

llm-benchmark benchmark --model "gpt-oss:20b" --tool "Ollama"

The client prompts for context length and thinking mode, and for the KV cache dtype on Unsloth Studio. Sampling is left at the model default — the values above are what the tool reported using, not overrides the client sent.
