Shortfixes the bug : ggml\src\ggml-cuda\cpy.cu:614: ggml_cuda_cpy_fn: unsupported type combination (q6_0 to f16) encountered when trying to use deepseek lite v2 with quantized K cache. Note: I compile my IK_Llama with GGML_CUDA_F16.
To fix this, I added a cpy_blck_q_f16 function devised by comparing the cpy_blck_q8_0_f32 and cpy_blck_q8_0_f16, and transposing the difference for the other legacy quants on the basis of the cpy_blck_q_f32 function. A "rule of three" of sorts.
Perplexity test and inference now works consistantly on -ctk q4_0 ; q4_1 ; q5_0 ; q5_1 in that scenario, with expected values and behavior.
Except on Q6_0, which sees its perplexity multiplied by 100. (I suspect the Cuda dequantize_q6_0 to be incompatible with this PR for some reason, but that's beyond what I can fix)
-ctk iq4_nl, which doesn't have yet a dequantize_iq4_nl function, is not usable that way for now.

webui: auto-refresh /props on inference start to resync model metadata (#16784)
* webui: auto-refresh /props on inference start to resync model metadata
- Add no-cache headers to /props and /slots
- Throttle slot checks to 30s
- Prevent concurrent fetches with promise guard
- Trigger refresh from chat streaming for legacy and ModelSelector
- Show dynamic serverWarning when using cached data
* fix: restore proper legacy behavior in webui by using unified /props refresh
Updated assistant message bubbles to show each message's stored model when available,
falling back to the current server model only when the per-message value is missing
When the model selector is disabled, now fetches /props and prioritizes that model name
over chunk metadata, then persists it with the streamed message so legacy mode properly
reflects the backend configuration
* fix: detect first valid SSE chunk and refresh server props once
* fix: removed the slots availability throttle constant and state
* webui: purge ai-generated cruft
* chore: update webui static build

* webui: add OAI-Compat Harmony tool-call live streaming visualization and persistence in chat UI
- Purely visual and diagnostic change, no effect on model context, prompt
construction, or inference behavior
- Captured assistant tool call payloads during streaming and non-streaming
completions, and persisted them in chat state and storage for downstream use
- Exposed parsed tool call labels beneath the assistant's model info line
with graceful fallback when parsing fails
- Added tool call badges beneath assistant responses that expose JSON tooltips
and copy their payloads when clicked, matching the existing model badge styling
- Added a user-facing setting to toggle tool call visibility to the Developer
settings section directly under the model selector option

The handle_apply_template handler was defined but never registered as
an HTTP endpoint, causing 404 errors when calling POST /apply-template.
This commit adds the missing endpoint registration to match the
functionality available in llama.cpp mainline.
Co-authored-by: Gapeleon <gapeleon@users.noreply.github.com>
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 #723. Then, after #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.
* Fix changes meaning warnings

* Fix q5_0_r4
The issue waqs in the tail part. As almost all models have tensor
rows that are multiple of 128, that part was never triggered in testing.
But ithe gpt-oss models have an embedding size of 2880, so we end
up there and trigger the bug.

so more recent users that haven't followed the history of FlashMLA
evolution and hence don't know about the MLA options get the best setting
without having to add -mla 3 on the command line.

* Use new-new-mma also for MLA=3, and use mask bounds
This gives us ~25% better PP at 32k tokens compared to main
