Set those in LM Studio, then:
llm-benchmark benchmark --model "openai/gpt-oss-20b" --tool "LM Studio"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.
