Tarek DakhranandXuan Son Nguyen 8ca4060b7e server : add realtime conversation and transcription on /v1/realtime (#31269)
* server : add realtime conversation and transcription on /v1/realtime

Co-authored-by: Xuan Son Nguyen <son@huggingface.co>
Assisted-by: Claude Opus 5.5

* examples : default the realtime client to the server port 9931

Assisted-by: Claude Opus 5.5

* server : sample realtime responses right after their own decode

Slots respond in turns on one context: sampling at the start of the next step read the logits of whichever slot decoded last, so concurrent sessions mixed their outputs.

Assisted-by: Claude Opus 5.5

* move more stuff to server-realtime, making it self-contained

* examples : fix the type check of the realtime client

Assisted-by: Claude Opus 5.5

* examples : use the model card prompts in the realtime client

2D convolutions with kernel size 9 produced different results on SVE

Use svmla_f32_m(pg, sum1, ax1, ay1) so inactive lanes retain sum1.

Tarek DakhranandPiotr Wilkin c5897995a7 mtmd : chat : Fix extra \n between text and media marker (#19595)
* mtmd : chat : Fix extra \n between text and media marker

Thanks to @tugot17 for detecting and reporting the issue.

For vision models (e.g. LFM2.5-VL-1.6B and Qwen/Qwen3-VL-4B-Instruct) `llama-mtmd-cli` produces identical output to HF implementation.

However `llama-server` doesn't. I traced it down to extra newline
inserted after `<__media__>`.

This happens in `to_json_oaicompat`, that treats media markers as text
and joins all parts with `\n` separator.

PR introduces new type `media_marker` and uses it for media markers.
Extra logic is added to prevent insertion of newlines before and after
media markers.

With this change number of input tokens is identical to HF
implementation and as a result the output is also identical.

I explored other ways to address the issue
* remove completely `\n` between text parts in `to_json_oaicompat`
* merge text messages in server-common.cpp before sending them to `to_json_oaicompat`

Please propose alternative ways of fixing this issue.

* Refactor to use explicite per type ifs

* Update common/chat.cpp

* model : Add tokenizer from LFM2.5-Audio-1.5B

[LFM2.5-Audio-1.5B](https://huggingface.co/LiquidAI/LFM2.5-Audio-1.5B) introduced lightweight audio tokenizer.

Tokenizer based on LFM2 architecture and acts as "embedding" model with
different input `n_embd` and output `n_embd_out`.

To be used in https://github.com/ggml-org/llama.cpp/pull/18641.

To convert use

```shell
python3 convert_hf_to_gguf.py /path/to/LFM2.5-Audio-1.5B/audio_detokenizer
```

* Update convert_hf_to_gguf.py

* Formatting

* Rework check for attention layers

* Add LFM2 SWA model support

* Address PR feedback

* Set vocab to none

* Move helper function definitions to cpp file
