firecoperana ab1d74074b common : introduce composable PEG parser combinators for chat parsing and new jinja template engine (#1369) 
---------

Co-authored-by: Piotr Wilkin <piotr.wilkin@syndatis.com>

common : add nemotron 3 parsing (#18077)

common : add parser for ministral/mistral large 3/devstral 2 (#17713)

common : default content to an empty string (#18485)

chat: make tool description and parameters optional per OpenAI spec (#18478)

Per the OpenAI API specification, both 'description' and 'parameters'
fields in tool function definitions are optional. Previously, the parser
would throw an exception if these fields were missing.

jinja : implement mixed type object keys (#18955)

---------

Co-authored-by: Xuan Son Nguyen <son@huggingface.co>

jinja : undefined should be treated as sequence/iterable (return string/array) by filters/tests (#19147)

`tojson` is not a supported `undefined` filter

keep it DRY and fix some types

jinja : do not pass empty tools and add some none filters (#19176)

jinja : add unordered_map include to value.h [no ci] (#19205)

jinja : add missing 'in' test to template engine (#19004) (#19239)

The jinja template parser was missing the 'in' test from
global_builtins(), causing templates using reject("in", ...),
select("in", ...), or 'x is in(y)' to fail with
"selectattr: unknown test 'in'".

This broke tool-calling for Qwen3-Coder and any other model
whose chat template uses the 'in' test.

Added test_is_in supporting array, string, and object containment
checks, mirroring the existing 'in' operator logic in runtime.cpp.

Includes test cases for all three containment types plus
reject/select filter usage.

chat: fix case where template accepts type content only (#19419)

mtmd : chat : Fix extra \n between text and media marker (#19595)

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.

# ik_llama.cpp: llama.cpp fork with better CPU performance
[![License: MIT](https://img.shields.io/badge/license-MIT-blue.svg)](https://opensource.org/licenses/MIT)
## TL;DR
This repository is a fork of [llama.cpp](https://github.com/ggerganov/llama.cpp) with better CPU and hybrid GPU/CPU performance, new SOTA quantization types, first-class Bitnet support, better DeepSeek performance via MLA, FlashMLA, fused MoE operations and tensor overrides for hybrid GPU/CPU inference, row-interleaved quant packing, etc.
>[!NOTE]
>The only fully functional and performant compute backends are CPU (`AVX2` or better, `ARM_NEON` or better) and CUDA.
>Please do not enter issues related to ROCm, Vulkan, Metal, etc. They will not get resolved unless you roll up your sleeves and help bring your favorite backend up to speed. With the current regular contributors this project simply does not have the bandwidth to work on all backends available in `llama.cpp`.
>[!IMPORTANT]
>Do not use quantized models from Unsloth that have `_XL` in their name. These are likely to not work with `ik_llama.cpp`.
>
>The above has caused some stir, so to clarify: the Unsloth `_XL` models that are likely to not work are those that contain `f16` tensors (which is never a good idea in the first place). All others are fine.
## Quickstart
### Prerequisites
```
git clone https://github.com/ikawrakow/ik_llama.cpp
cd ik_llama.cpp
```
On Debian/Ubuntu Linux, install the required packages (if using another Linux distro, you need to find the corresponding packages and adapt):
```
apt-get update && apt-get install build-essential git libcurl4-openssl-dev curl libgomp1 cmake
```
### Build for CPU
```
cmake -B build -DGGML_NATIVE=ON
cmake --build build --config Release -j$(nproc)
```
### Build for GPU
Install Nvidia Drivers and [CUDA Toolkit](https://developer.nvidia.com/cuda/toolkit).
```
cmake -B build -DGGML_NATIVE=ON -DGGML_CUDA=ON
cmake --build build --config Release -j$(nproc)
```
### Run
Download `.gguf` model files (e.g. [bartowski/Qwen_Qwen3-0.6B-IQ4_NL.gguf](https://huggingface.co/bartowski/Qwen_Qwen3-0.6B-GGUF/blob/main/Qwen_Qwen3-0.6B-IQ4_NL.gguf)) to your favorite directory (e.g. `/my_local_files/gguf`).
Start the server with one of the commands (CPU or GPU):
```
./build/bin/llama-server --model /my_local_files/gguf/Qwen_Qwen3-0.6B-IQ4_NL.gguf --ctx-size 4096
```
```
./build/bin/llama-server --model /my_local_files/gguf/Qwen_Qwen3-0.6B-IQ4_NL.gguf --ctx-size 4096 -ngl 999
```
That's all! Open [http://127.0.0.1:8080](http://127.0.0.1:8080) in Browser start chatting.

## Resources
There is no single point of reference describing all new `ik_llama.cpp` features. Pull requests often contain detailed information, so browsing the PRs is often the best way to learn about new features and how to use them. In addition
* [The Wiki page](https://github.com/ikawrakow/ik_llama.cpp/wiki) has performance comparisons to mainline `llama.cpp`
* [This guide](https://github.com/ikawrakow/ik_llama.cpp/discussions/258) is a good place to start if you came here because of DeepSeek models
* [This discussion](https://github.com/ikawrakow/ik_llama.cpp/discussions/266) is about running DeepSeek-V3/R1 on a 16 x 3090 setup
* [This discussion](https://github.com/ikawrakow/ik_llama.cpp/discussions/8) describes the new quantization types available in `ik_llama.cpp`
## Testing
### Function Calls Tests
To run the function calls test suite:
```bash
cd build
cmake --build . --target test-function-calls
./bin/test-function-calls
```
The test suite covers parser functionality, streaming, error handling, content cleaning, and server integration. All tests should pass to ensure production readiness.

#### Seminal papers and background on the models
If your issue is with model generation quality, then please at least scan the following links and papers to understand the limitations of LLaMA models. This is especially important when choosing an appropriate model size and appreciating both the significant and subtle differences between LLaMA models and ChatGPT:
- LLaMA:
- [Introducing LLaMA: A foundational, 65-billion-parameter large language model](https://ai.facebook.com/blog/large-language-model-llama-meta-ai/)
- [LLaMA: Open and Efficient Foundation Language Models](https://arxiv.org/abs/2302.13971)
- GPT-3
- [Language Models are Few-Shot Learners](https://arxiv.org/abs/2005.14165)
- GPT-3.5 / InstructGPT / ChatGPT:
- [Aligning language models to follow instructions](https://openai.com/research/instruction-following)
- [Training language models to follow instructions with human feedback](https://arxiv.org/abs/2203.02155)
## Completions
Command-line completion is available for some environments.
#### Bash Completion
```bash
$ build/bin/llama-cli --completion-bash > ~/.llama-completion.bash
$ source ~/.llama-completion.bash
```
Optionally this can be added to your `.bashrc` or `.bash_profile` to load it
automatically. For example:
```console
$ echo "source ~/.llama-completion.bash" >> ~/.bashrc
```
