mudler-agentandEttore Di Giacinto c60a2e47d6 feat(backends): timestral.cpp forecast backend and /v1/forecast API (#12885)
* feat(grpc): add a Forecast RPC for time-series models

Add Forecast to the backend service with columnar request and response
messages: flat row-major arrays, NaN for missing values, and one message
per series so a caller can send series of different shapes in one call.
The response keeps the request order.

Wire the RPC through the server, client, embedded client, connection
evicting client, in-flight tracking client and the base backend, which
answers unimplemented. core/backend gains a Forecast helper that stamps
the model identity and records a trace, like the other single-purpose
RPCs.

* feat(config): add the forecast usecase

FLAG_FORECAST marks a model as a time-series forecaster. The timestral-cpp
backend declares it as its default usecase, so a config with that backend
needs no extra lines. The backend is also listed as a non-text backend, so
a forecast model is never offered as a chat model. It shows up in the
gallery filter and in the capability list.

* feat(api): add POST /v1/forecast

Take one or more numeric series and return quantile trajectories for the
next prediction_length steps. Targets are [variates][steps] or a flat
array for one variate; JSON null marks a missing value. Past and known
covariates and categorical codes are checked for length before the
backend sees them. Quantiles default to 0.1, 0.5 and 0.9 in the backend.

The route is gated by a new default-on forecast API feature. The endpoint
is listed in the swagger spec, the /api/instructions index, the UI model
filter and the capability symbols.

* feat(backends): add the timestral-cpp forecast backend

Wrap the timestral.cpp C ABI with purego, the way the other ggml
backends do: libtimestral is built from a pinned commit with ggml
embedded, and the Go binary loads it at start.

Forecast validates the counts against the array lengths, groups the
series by shape, makes one library call per group and puts the results
back in the order the caller sent them. Quantiles default to 0.1, 0.5
and 0.9, and a level the model does not have is refused with the list of
valid ones. A mutex guards the handle because the library is not
reentrant. Request size is bounded by two model options.

The unit specs use a fake library. The integration specs and a gRPC
spec run against the 5M F32 model that test.sh downloads and checks
against a fixed SHA-256.

Assisted-by: Claude:claude-sonnet-5-5 go-vet

* build(backends): register timestral-cpp in the build and the library

Add the CPU image to the backend matrix for amd64 and arm64, plus an
Apple silicon entry that is not built or tested yet. The image has no GPU
keys because the engine runs on the CPU only. Wire the make targets, the
path filter and the dependency bump bot.

The library entries were generated with backendcatalog. The images are
not published yet, so the release entries are unpinned until a
maintainer runs --repin. The gallery reader test now counts the names in
the library instead of a fixed number, so adding a backend does not
break it.

Assisted-by: Claude:claude-sonnet-5-5 go-vet

* feat(gallery): add the Timestral forecast models

Add Timestral 5M, 28M, 123M and 209M as F32 entries, each with its F16
build as a variant. Q8_0 and the K-quants are left out until the quality
question is settled. Each entry runs on the timestral-cpp backend, on
the CPU only.

The weights use Mistral's Modified MIT licence, which bars use by
companies above a monthly revenue threshold. The first paragraph after
the summary says so, the licence file is installed next to the weights,
and the revenue-restricted-license tag makes the entries filterable.

The memory each build needs has not been measured, so no size is set.

Assisted-by: Claude:claude-sonnet-5-5

* docs(forecast): document /v1/forecast and the Timestral models

Add a feature page with the request and response shapes, the error
cases, the model options and the licence note. List the engine in the
README, the compatibility table and the backend categories.

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

A small LocalAI core with backends (llama.cpp, vLLM, MLX, whisper.cpp, stable-diffusion, kokoro, parakeet.cpp...) plugged in as separate on-demand images

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
vllm.cpp From-scratch C++20 port of vLLM for text generation: paged KV cache, continuous batching, prefix caching, safetensors + GGUF loading, engine-enforced structured output, on CPU, CUDA, Metal and Vulkan. Also serves MiniMax-H3 joint video+audio generation
parakeet.cpp C++/GGML port of NVIDIA NeMo Parakeet ASR (tdt/ctc/rnnt/hybrid), with cache-aware streaming transcription
moss-transcribe.cpp C++/GGML port of OpenMOSS MOSS-Transcribe-Diarize: joint long-form transcription, speaker diarization and timestamping in a single pass

timestral.cpp Mistral Timestral time-series forecasting: quantile forecasts with covariates, on the CPU
free-splatter.cpp Pose-free 3D reconstruction (FreeSplatter): turns a handful of plain photos into 3D Gaussians, no camera poses or GPU required
trellis2.cpp C++/GGML port of Microsoft TRELLIS.2: single-image to textured 3D mesh (GLB with PBR materials)
gem-x.cpp Live human motion capture with SOMA and SMPL pose streams (CPU/Vulkan)
kimodo.cpp C++/GGML text-to-motion on CPU and Vulkan, exported as animated skeleton GLB
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.
