Top-nσ support was added in #11223, where it was implemented as a special case that ignored samplers other than
top_kandtemperaturewhentop_n_sigmawas present.Following #11896 (comment), this PR integrates this sampler into the main sampling chain. This removes the special case handling and makes it possible to combine
top_n_sigmawith other sampling methods likemin_p.I have used #11896 as a starting point, so this PR also makes
top_n_sigmaavailable in llama-server.Verification
I have tested it with llama-server and it seems to work. Below are the top probabilities after
My name iswithtop_n_sigma=1(left) andtop_n_sigma=5(right).
