 via `ModelOptions.Options[] = "kv_cache_dir:/some/path"`. Format is **our own** -
 NOT bit-compatible with ds4-server's KVC files (interop is a follow-up plan).
 
-## Engine options (LoadModel)
-
-`LoadModel` maps `ModelOptions.Options[]` (`"key:value"`, from model-YAML
-`options:`) onto `ds4_engine_options` through a **declarative table**
-(`kEngineOptSpecs` + `apply_engine_option` in `grpc-server.cpp`). The struct is
-plain C with no reflection, so the field set is enumerated once in the table;
-adding a future engine knob is a one-line table row, not a new branch. Unknown
-keys are ignored (back-compat). A bare flag (`ssd_streaming` with no value)
-means `true`. Path-type values (`mtp_path`, `expert_profile_path`,
-`directional_steering_file`) resolve **relative to the model directory**, so a
-gallery entry can reference a companion file it downloaded by bare filename;
-absolute values pass through. `ds4_role` / `ds4_layers` / `ds4_listen` /
-`ds4_route_timeout` / `kv_cache_dir` keep their dedicated handling (validation
-+ coordinator wiring) and are not in the table.
-
-Wired keys: `mtp_path`, `mtp_draft`, `mtp_margin`, `prefill_chunk`,
-`power_percent`, `warm_weights`, `quality`, `ssd_streaming`,
-`ssd_streaming_cold`, `ssd_streaming_preload_experts`,
-`ssd_streaming_cache_experts` (count or `NGB`, sets both experts+bytes via
-`ds4_parse_streaming_cache_experts_arg`), `simulate_used_memory` (`NGB` via
-`ds4_parse_gib_arg`), `expert_profile_path`, `directional_steering_file`,
-`directional_steering_attn`, `directional_steering_ffn`.

-## SSD streaming (running models larger than RAM)
-
-ds4's **SSD streaming** keeps non-routed weights resident and streams routed MoE
-experts from the GGUF on cache misses, turning "does it fit in RAM" into a speed
-spectrum. **Metal (Darwin) only** - it is a no-op on CUDA/CPU. Enable with
-`options: ["ssd_streaming"]`; size the routed-expert cache with
-`ssd_streaming_cache_experts:NGB` (omit for ds4's automatic 80%-of-working-set
-budget). Gallery entries built on this: `deepseek-v4-flash-q4-ssd` (153 GB Flash
-on a 128 GB Mac) and `deepseek-v4-pro-q2-ssd` (433 GB Pro, experimental).

 **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.

 ## Supported Backends & Acceleration
 
-LocalAI supports **60+ backends** including llama.cpp, vLLM, SGLang, transformers, whisper.cpp, diffusers, MLX, MLX-VLM, and many more. Hardware acceleration is available for **NVIDIA** (CUDA 12/13), **AMD** (ROCm), **Intel** (oneAPI/SYCL), **Apple Silicon** (Metal), **Vulkan**, and **NVIDIA Jetson** (L4T). All backends can be installed on-the-fly from the [Backend Gallery](https://localai.io/backends/).

-### 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:

-| [voxtral.c](https://github.com/mudler/voxtral.c) | Voxtral Realtime 4B speech-to-text in pure C |
-| [vibevoice.cpp](https://github.com/mudler/vibevoice.cpp) | Native port of Microsoft VibeVoice for TTS (voice cloning) and long-form ASR with speaker diarization |
-| [rf-detr.cpp](https://github.com/mudler/rf-detr.cpp) | Native RF-DETR object detection and instance segmentation |
-| [locate-anything.cpp](https://github.com/mudler/locate-anything.cpp) | Open-vocabulary object detection and visual grounding (LocateAnything-3B) |
-| [depth-anything.cpp](https://github.com/mudler/depth-anything.cpp) | Depth Anything 3 monocular metric depth + camera pose estimation |
-| [privacy-filter.cpp](https://github.com/localai-org/privacy-filter.cpp) | Standalone GGML PII/NER token-classification engine powering LocalAI's PII redaction tier |
