* fix(ik-llama): port multimodal path to mtmd API and bump to f96eaddb (#10534) The IK_LLAMA_VERSION bump to f96eaddba8bed6a9a5e628bbf6a566775c70b49c pulls in upstream commit "Prune examples/llava", which deletes examples/llava (clip.* / llava.*). The ik-llama backend's grpc-server.cpp built a local `myclip` library from those files and called the removed clip/llava C API, so the bump no longer builds. ik_llama keeps its multimodal stack in the surviving `mtmd` library (examples/mtmd/, public headers mtmd.h + mtmd-helper.h). This ports the backend's multimodal path onto the high-level mtmd_* / mtmd_helper_* API in place, leaving the text path (which still uses ik_llama's retained old common API) untouched: - Makefile: bump IK_LLAMA_VERSION to f96eaddb. - prepare.sh: drop the clip/llava source copy + sed block; mtmd is a library target, no source copy needed. - CMakeLists.txt: remove the `myclip` target; link `mtmd` and add its include dir; build grpc-server as C++17 (mtmd headers require it). - patches: drop 0002 (targeted the deleted examples/llava/clip.cpp; the mtmd clip.cpp never calls ggml_quantize_chunk, so the fix is unneeded). Keep 0001 (verified still applies). - grpc-server.cpp / utils.hpp: replace clip_model_load + clip_image_load_from_bytes + llava_image_embed_make_with_clip_img + the manual [img-N] prefix splitting and per-image llava_embd_batch decode loop with mtmd_init_from_file (moved after the model load, which it requires), mtmd_helper_bitmap_init_from_buf, mtmd_tokenize and mtmd_helper_eval_chunks. Legacy [img-N] tags are translated, in order, into mtmd media markers (mtmd_default_marker()); the post-image suffix text stays on the normal token path so the sampling loop is unchanged. Supersedes #10534.

Our grpc-server.cpp/utils.hpp kept a plain `nlohmann::json` alias, which now collides with mtmd.h once it is included for the multimodal port: "conflicting declaration 'using json = ...'". Switch our two aliases to ordered_json to match; it is API-compatible (utils.hpp already used ordered_json for its log helper) and our json never crosses into an unordered-json API.

LocalAI is the open-source AI engine. Run any model - LLMs, vision, voice, image, video - on any hardware. No GPU required.
A small core, not a bundle. Each backend wraps a best-in-class engine (llama.cpp, vLLM, whisper.cpp, stable-diffusion, MLX...) in its own image, pulled only when a model needs it. You install nothing you don't use.
- Composable by design: backends are separate and pulled on demand, so you install only what your model needs
- Open and extensible: load any model, or build your own backend in any language against an open interface
- Drop-in API compatibility: OpenAI, Anthropic, and ElevenLabs APIs across every backend
- Any model, any modality: LLMs, vision, voice, image, and video behind one API
- Any hardware: NVIDIA, AMD, Intel, Apple Silicon, Vulkan, or CPU-only
- Multi-user ready: API key auth, user quotas, role-based access
- Built-in AI agents: autonomous agents with tool use, RAG, MCP, and skills
- Privacy-first: your data never leaves your infrastructure

Backends built by us
Most backends wrap a best-in-class upstream engine. A handful of them are native C/C++/GGML engines (no Python at inference) developed and maintained by the LocalAI project itself:
| Backend | What it does |
|---|---|
| parakeet.cpp | C++/GGML port of NVIDIA NeMo Parakeet ASR (tdt/ctc/rnnt/hybrid), with cache-aware streaming transcription |
| ced.cpp | C++/GGML port of the CED audio-tagging models: sound-event classification (527-class AudioSet) over REST and the realtime API for live recognition |
| voxtral.c | Voxtral Realtime 4B speech-to-text in pure C |
| vibevoice.cpp | Native port of Microsoft VibeVoice for TTS (voice cloning) and long-form ASR with speaker diarization |
| rf-detr.cpp | Native RF-DETR object detection and instance segmentation |
| locate-anything.cpp | Open-vocabulary object detection and visual grounding (LocateAnything-3B) |
| depth-anything.cpp | Depth Anything 3 monocular metric depth + camera pose estimation |
| privacy-filter.cpp | Standalone GGML PII/NER token-classification engine powering LocalAI's PII redaction tier |
| LocalVQE | Joint acoustic echo cancellation, noise suppression, and dereverberation |
| local-store | Local-first vector database for embeddings (shipped in-tree) |
We also maintain apex-quant, a per-tensor, per-layer quantization recipe for Mixture-of-Experts models that exploits their structural sparsity to produce GGUFs matching or beating Q8_0 quality - and they run out of the box on stock llama.cpp.
