-|---|--:|--:|
-| MLX **gated to prefill** (pin >= 89c46aeb) | **524.5 ms** | **24.37 tok/s, 97.6% of MLX-LM** |
-| MLX ungated (older pins) | 537 ms | 12.7 tok/s |
-| MLX off | 602 ms | 23.9 tok/s, 95.9% |
-
-Ratios are against an MLX-LM baseline measured INTERLEAVED with ours over four
-ABBA blocks (its spread 0.34%, ours 0.12%). An earlier revision of this file
-claimed 99.1%; that used a two-run MLX-LM baseline containing an outlier and
-overstated us by about 1.5 points.
-
-**`VLLM_CPP_VERSION` and this flag are coupled.** Moving the pin back before
-`89c46aeb` while leaving `VLLM_CPP_MLX=on` would take the middle row — roughly
-half throughput. If you roll the pin back, roll the default back with it.
-
-One caveat: MLX's GEMM is not bit-identical to the native kernel, so an MLX build
-produces a different greedy sequence than a non-MLX one. That is a property of the
-provider, not of the gate, and it predates this packaging. Full disposition in
-vllm.cpp `docs/BENCHMARKS.md`.
-
-Build knobs:
-
-- `VLLM_CPP_MLX=off` builds Metal without the provider: ~124 MB smaller, and
-  96.4% of MLX-LM instead of 99.1%.
-- `MLX_VERSION` pins the wheel (default `0.29.4`). MLX is consumed as the
-  prebuilt pip wheel because building it from source needs `xcrun metal`, i.e. a
-  full Xcode the macOS runners do not have.
-
-Packaging vendors `libmlx.dylib`, `mlx.metallib` and MLX's MIT license into
-`package/lib/`, and rewrites `libvllm.dylib`'s rpath to `@loader_path/lib`
-(re-signing it, since `install_name_tool` invalidates the signature). The
-metallib must stay beside `libmlx.dylib`: MLX looks for it there.
-
 Testing: `make test` runs the unit specs; export `VLLM_CPP_MODEL=<model>` (and
 optionally `VLLM_CPP_LIBRARY=<libvllm path>`) to enable the e2e specs.

-    ALPHA development builds. Try it, but llama-cpp stays the recommendation for

-
-    vllm.cpp is an Apache-2.0 C++20 inference engine maintained by the LocalAI team,
-    developed in its own repository and usable without LocalAI. It began as a port of
-    vLLM and keeps vLLM as its reference implementation, checking output against it and
-    benchmarking against it, while growing a featureset of its own. It implements vLLM's
-    V1 architecture (paged KV cache, continuous batching, prefix caching, scheduler,
-    sampler) on a portable tensor runtime with no Python, PyTorch or ggml at inference
-    time. It loads GGUF as well as Hugging Face safetensors, supports structured output
-    (JSON schema / regex / choice / GBNF grammar) enforced in-engine, ships speculative
-    decoding and KV offload, and runs on CPU, NVIDIA CUDA (Blackwell-family), Apple
-    Metal and Vulkan.
-
-    The project is expected to be renamed as it diverges further from vLLM; the new
-    name is still to be decided.

-### Verifying OCI Backends
-
-Backend galleries can require keyless Sigstore signatures for every OCI image
-they provide. Add a `verification` policy to the gallery configuration, then
-enable strict integrity mode:
-
-```bash
-export LOCALAI_BACKEND_GALLERIES='[{"name":"localai","url":"github:mudler/LocalAI/backend/index.yaml@master","verification":{"issuer":"https://token.actions.githubusercontent.com","identity_regex":"^https://github\\.com/mudler/LocalAI/\\.github/workflows/backend_merge\\.yml@refs/(heads/master|tags/.+)$"}}]'
-export LOCALAI_REQUIRE_BACKEND_INTEGRITY=1
-local-ai run
-```
-
-The policy pins the Fulcio issuer and the GitHub Actions workflow identity that
-signed the image. The identity expression covers development images produced
-from `master` and release images produced from tags. Use a narrower expression
-if your deployment only accepts one release channel.
-
-Without strict mode, an OCI gallery without a verification policy installs
-with a warning. With strict mode, LocalAI refuses galleries without a policy,
-images without a compatible Sigstore bundle, and signatures that do not match
-the configured identity. Existing images published before bundle signing was
-enabled must be rebuilt or re-signed before strict deployments can install
-them.
-
-An optional `not_before` RFC3339 value revokes signatures logged before that
-time. Advance it after a signing-workflow compromise, then rebuild or re-sign
-the trusted images:
-
-```json
-{
-  "verification": {
-    "issuer": "https://token.actions.githubusercontent.com",

-#### Configuring the engine with `engine_args`
-
-The same `engine_args:` map the vLLM and SGLang backends accept is honoured
-here, with keys spelled exactly as vLLM's own CLI flags - so a `speculative_config`
-or `kv_transfer_config` block written for vLLM works verbatim. Unknown keys are
-ignored rather than fatal; the engine validates the documents it is handed and
-reports a precise error at load.
-
-```yaml
-name: qwen35-a3b
-backend: vllm-cpp
-parameters:
-  model: "Qwen/Qwen3.5-A3B"
-context_size: 16384
-template:
-  use_tokenizer_template: true
-engine_args:
-  # KV cache sizing: num_blocks * block_size tokens of cache.
-  block_size: 32
-  num_blocks: 1024
-  # Concurrency and the per-step chunked-prefill token budget.
-  max_num_seqs: 32
-  max_num_batched_tokens: 8192
-  # Automatic prefix caching. Omit to keep the model's own default
-  # (on for dense models, off for hybrid / attention-free ones).
-  enable_prefix_caching: true
-  # Scheduler admission order: fcfs (default), priority, or lpm
-  # (cache-aware longest-prefix-match; needs prefix caching to have any effect).
-  scheduling_policy: lpm
-```
-
-| Key | Meaning | Default |
-|-----|---------|---------|
-| `block_size` | KV-cache block size, in tokens per block | 32 |
-| `num_blocks` | KV-cache blocks to allocate | 256 |
-| `max_model_len` | Max sequence length; also settable as `context_size` / `max_model_len` | model config |
-| `max_num_seqs` | Max concurrent sequences the scheduler admits | 8 |
-| `max_num_batched_tokens` | Per-step chunked-prefill token budget | per-arch (2048 dense, 4096/8192 MoE) |
-| `enable_prefix_caching` | Automatic prefix caching; `enable_radix_attention` is an accepted alias | model default |
-| `enable_jump_forward` | Jump-forward decoding, which emits grammar-forced tokens without a model step. Only affects constrained requests (`grammar`, JSON schema) | off |
-| `scheduling_policy` | `fcfs`, `priority`, or `lpm` | `fcfs` |
-| `tool_parser` / `reasoning_parser` | Force a parser instead of chat-template auto-detection | auto |
-| `tokenizer_config` | Override the `tokenizer_config.json` the chat template is read from | `<model_dir>/tokenizer_config.json` |
-| `speculative_config` | Speculative decoding (see below) | disabled |
-| `kv_transfer_config` | External KV connector / LMCache (see below) | none |
-
-Raising `max_num_batched_tokens` lets more prefill land in a single step, at the
-cost of decode latency for requests queued behind it. The default deliberately
-does not scale with `max_num_seqs`, which is what keeps a large concurrent
-prefill from blowing up the per-step activation on the hybrid architectures.
-
-`enable_prefix_caching` and `enable_jump_forward` are tri-state at the engine
-boundary: omitting the key defers to a default (the model's own capability for
-prefix caching, an environment variable for jump forward), while an explicit
-`false` forces the feature off. Those are genuinely different - prefix caching
-defaults *on* for dense models - so write the key only when you mean to override.
-
-#### Speculative decoding
-
-`speculative_config:` takes the same JSON object as vLLM's
-`--speculative-config`. Three methods are supported.
-
-> **Architecture limit.** At the current engine pin, `mtp` and `dflash` are
-> **Qwen3.5 / Qwen3.6 only**. The engine builds a widened speculative KV cache
-> directly for those families rather than through the model registry, so a
-> speculative config on any other architecture (Llama, GLM, Gemma, Mistral, ...)
-> will not work regardless of checkpoint format. `ngram` needs no draft weights
-> and is not subject to this limit.
-
-> **Format support.** `mtp` and `dflash` now work from a `.gguf` target as well
-> as safetensors. An MTP head is read from the GGUF's `nextn.*` tensors when the
-> file declares `<arch>.nextn_predict_layers`; a GGUF exported WITHOUT the head
-> (converted with `--no-mtp`, or predating llama.cpp's Qwen3.5 MTP support) is
-> refused at load naming that as the reason. A DFlash draft may itself be a
-> `dflash`-arch GGUF, and the target may be a GGUF too. `ngram` needs no draft
-> weights and works on any format.
-
-**MTP** (Multi-Token Prediction) uses a draft head shipped inside the target
-checkpoint's own `mtp.*` tensors, so there is no second model to download. It
-requires a **safetensors** checkpoint - the `mtp.*` tensors do not survive GGUF
-conversion, and an MTP config over a `.gguf` model is rejected at load.
-
-```yaml
-engine_args:
-  speculative_config:
-    method: mtp
-    # Optional; defaults to the checkpoint's own head depth, which is
-    # usually the right value. Must be a multiple of that depth.
-    num_speculative_tokens: 1
-```
-
-**DFlash** uses a separate block-diffusion drafter that proposes a whole block
-of tokens in one non-autoregressive forward pass. Unlike MTP, the draft is its
-own checkpoint, so `model:` is **required**:
-
-```yaml
-engine_args:
-  speculative_config:
-    method: dflash
-    model: z-lab/Qwen3.6-27B-DFlash
-    num_speculative_tokens: 4
-```
-
-The draft shares the *target's* `embed_tokens` and `lm_head`, so both must come
-from the same model family and the target must be safetensors.
-
-**The engine does not download the draft.** `model:` is resolved, in order,
-as a path as given, then as the last path segment under LocalAI's models
-directory (`z-lab/Qwen3.6-27B-DFlash` → `<models>/Qwen3.6-27B-DFlash`, which is
-what LocalAI's own downloader produces), then as the whole reference under the
-models directory. Install the draft into LocalAI first, or give an absolute path
-to a directory containing `config.json`. If none of those resolve, the load
-fails immediately naming every location that was tried, rather than reporting a
-missing checkpoint from inside the engine.
-
-**N-gram** needs no draft model at all - it proposes from the prompt's own
-suffix history. `num_speculative_tokens` is required:
-
-```yaml
-engine_args:
-  speculative_config:
-    method: ngram
-    num_speculative_tokens: 4
-    prompt_lookup_min: 5
-    prompt_lookup_max: 5
-```
-
-> **Auto-configuration on import.** When you import a safetensors repository
-> with `backend: vllm-cpp`, LocalAI reads the checkpoint's `config.json` and, if
-> it declares an MTP head (`mtp_num_hidden_layers`), writes
-> `speculative_config: {method: mtp}` into the generated `engine_args` for you.
-> An explicit `speculative_config` in your own config is never overwritten.
-> Importing a DFlash *draft* repository is refused with a warning: a drafter
-> cannot serve on its own, so import the target model and point
-> `speculative_config.model` at the draft.
-
-#### External KV cache with LMCache
-
-`kv_transfer_config:` takes vLLM's `--kv-transfer-config` JSON and selects an
-external KV-cache connector. The `lm://` LMCache client lets prefill KV be
-stored to and reloaded from a shared `lmcache.v1.server`, so a prefix computed
-by one replica does not have to be recomputed by the next:
-
-```yaml
-engine_args:
-  kv_transfer_config:
-    kv_connector: LMCacheConnector
-    kv_role: kv_both          # required whenever kv_connector is set
-    kv_connector_extra_config:
-      host: 127.0.0.1
-      port: 65432
-```
-
-`kv_role` is one of `kv_producer` (store only), `kv_consumer` (load only), or
-`kv_both`. An unregistered connector name, a missing role, or a malformed
-document fails the load with an explicit error rather than silently running
-without the cache.
-
-#### Legacy `options:` list
-
-Earlier versions configured this backend through the flat `options:` list, and
-those configs keep working. Every key in the table above is still read from
-there in `key:value` form, and `engine_args` wins on any key set in both:
-
-```yaml
-options:
-  - max_num_seqs:32
-  - enable_prefix_caching:true
-```
-
-New configs should prefer `engine_args:`, which is the only place the nested
-`speculative_config` / `kv_transfer_config` documents can be written naturally
-rather than as a single-line JSON string.

-## A new engine: vllm.cpp (alpha)
+## A new engine: vllm.cpp
 
-[vllm.cpp](https://github.com/mudler/vllm.cpp) is Apache-2.0 and maintained by the LocalAI team. We want it community-first rather than a LocalAI-only engine, so it lives in its own repository with its own docs, benchmark record and issue tracker, and it runs without LocalAI anywhere in the picture. It began as a C++20 port of vLLM. It ships here as the `vllm-cpp` backend ([#11100](https://github.com/mudler/LocalAI/pull/11100)). It implements vLLM's V1 architecture, so paged KV cache, continuous batching, prefix caching, scheduler and sampler, on a portable tensor runtime with no Python, no PyTorch and no ggml at inference. vLLM stays its reference implementation: correctness is checked by comparing output against it, and the benchmark scoreboard is kept against it.
-
-It has grown features vLLM does not have, which is most of the reason the port exists. It loads GGUF as well as safetensors, runs on CPU, Apple Metal and Vulkan alongside CUDA 12 and 13 and L4T for GB10, and ships speculative decoding and KV offload. Its benchmark page now measures against llama.cpp, MLX-LM and DwarfStar as well as vLLM, because on that hardware those are the engines it competes with. The project is expected to be renamed, with the new name still to be decided; it is drifting far enough that vllm.cpp will eventually mislead.
+[vllm.cpp](https://github.com/mudler/vllm.cpp) is a from-scratch C++20 port of vLLM, written and maintained by the LocalAI team under Apache-2.0, and it ships here as the `vllm-cpp` backend ([#11100](https://github.com/mudler/LocalAI/pull/11100)). It mirrors vLLM's V1 architecture, so paged KV cache, continuous batching, prefix caching, scheduler and sampler, on a portable tensor runtime with no Python, no PyTorch and no ggml at inference. It loads Hugging Face safetensors and GGUF, enforces structured output inside the engine (JSON schema, regex, choice, GBNF), and builds for CPU amd64 and arm64, CUDA 12 and 13 including Blackwell, L4T for GB10, Vulkan and Darwin Metal.
 
 Tool calling is at llama.cpp parity by construction, because chat deliberately reuses the same autoparser path: full minja chat templates, `tool_choice: auto` lowered to a lazy structural-tag decode constraint, 30 tool dialects, 7 reasoning parsers, and streamed `ChatDelta` and `ToolCallDelta`.

-The upstream page is careful about its own noise: on the 27B grid the run-to-run spread is 0.5% and c2 through c32 land between 0.7% and 1.7%, so it calls those five ties rather than wins. The concurrency-1 result is the one it stands behind.
-
-The DeepSeek-V4-Flash row is the one that shows how far this has moved from being a vLLM port. It runs DeepSeek-V4-Flash at roughly 2-bit (IQ2_XXS mixed, about 80 GB) on a single DGX Spark, decoding at 18.69 tok/s against DwarfStar's 16.33. At 300B+ total parameters even a 4-bit checkpoint is 156 GB or more, so a 2-bit GGUF is what fits inside the Spark's 119 GiB unified pool, and reading GGUF is what makes that possible.
-
-That number moved twice in a week, and the second move came from one lever. The dense Q8_0 projection tower was being read from the GGUF mmap over unified memory, which the GB10 reads about 20% slower per-GEMV than device memory. Staging that 6 GiB tower device-resident once at load, same bytes and same kernels, took decode from 16.23 to 18.69, generating the same tokens and using no more peak memory. The same change took Laguna-XS-2.1 from 87% of vLLM to 1.03x ahead of it.
-
-Speculative decoding is in similar shape: MTP on Qwen3.6-27B NVFP4 generates the same tokens as vLLM's MTP and runs about 4% faster at concurrency 1.

 ## LocalAI generates 3D models now
 
-3D generation is a new modality, so it had to be wired through the whole stack: a `Generate3D` RPC in `backend.proto`, a `FLAG_3D` capability so the loader knows which backends can serve it, and `POST /v1/3d/generations`.

 The first engine behind it is `trellis2cpp`, an image-to-3D backend over TRELLIS.2. You give it an image, you get a GLB back. The web UI has a page for it with a native GLB viewer, so you can turn the result around in the browser instead of downloading it to find out whether it worked, history kept in IndexedDB so a reload does not lose your generations, and previewable print remeshing for output you actually intend to send to a printer ([#10979](https://github.com/mudler/LocalAI/pull/10979)).

-## `local-ai chat` stopped being a REPL
-
-`local-ai chat` used to be a chat prompt in a terminal. It is now an agent, and it is the [nib](https://github.com/mudler/nib) harness compiled straight into the binary: tool use behind an approval gate, sub-agents, MCP servers, plugins and skills, auto-configured against your own instance. Nothing extra to install.
-
-```bash
-local-ai chat                      # the agent, pointed at your models
-echo "what is 2+2" | local-ai chat --cli
-local-ai chat --init zsh           # Ctrl+Space from any shell prompt
-```
-
-That last one prints a shell integration script (zsh, bash or fish), so you can pull the agent up from wherever you already are instead of opening something else.
-
-It runs shell commands now, so every tool call goes through an approval prompt you control, and read-only ones like `ls` and `cat` run without asking. If you had habits around the old REPL, a few things moved: `/clear` is gone and `/compact` is the closest thing, `/models` and `/model <name>` mean what they always meant, and switching model keeps the conversation instead of starting over ([#11291](https://github.com/mudler/LocalAI/pull/11291)).

 ## One backend, six audio endpoints
 
-The usual shape for audio is one backend per model family, which means a process per capability and a config file for each. `audio-cpp` wraps [audio.cpp](https://github.com/0xShug0/audio.cpp), a multi-family ggml audio engine. One backend process serves several unrelated families through a single runtime vocabulary, and works out which family a checkpoint belongs to from the GGUF's own `audiocpp.model_spec.family` metadata key. There is nothing backend-specific to write in the model config.

 The strip is now one line, permanently, showing a failure first and otherwise the least-advanced running operation, with a `+N more` pill. Its `✕` hides the strip and no longer cancels anything.
