Do you mean select like top K choices from the candidates?

No! my mean is given an option list, eg: [A,B,C,D,E] it can select multi option in llm decode, such as [A,C,D] or [D,B] or [D,A,E] ....., not using top-k selection Qinghan Lai Qilu University Of Technology(Shangdong Academy Of Sciences) On 10/23/2024 10:07，Byron ***@***.***> wrote： Do you mean select like top K choices from the candidates? — Reply to this email directly, view it on GitHub, or unsubscribe.

This multi option is very commonly used in our development tasks. The top k method will destroy the original output logic of the LLM and reduce the effect of generating text. I'd love to see sglang support that, as he's really helpful for tasks and can compensate for the limitations of single choice. Thanks!
