There was a problem hiding this comment.
Yep, that does the trick.

The logic to skip the logprobs of the stop token was originally from ggml-org/llama.cpp#2849, and was later modified as part of ggml-org/llama.cpp#10643 to be applied only to STOP_TYPE_WORD. The latter change wasn't included in ikawrakow#723. Then, after ikawrakow#958 got merged, the logic got inadvertently applied to GLM-4.5/4.6 and Kimi K2, resulting in truncated logprobs when streaming is off. This commit reverts the logic from ggml-org/llama.cpp#2849, such that the logprobs of the stop token will always be included in the response, when logprobs is enabled. From testing, this matches with the behavior of Fireworks inference server, for both chat completions and text completions endpoints. Also fix logprobs param handling for the text completion endpoint.

This fix the probabilities of stopping_word are included in the final response of
/completion.To test response without stream mode:
With stream mode (see the last event):
Or see the console output in the web UI.
