LocalAI [bot] 959de86761 feat(llama-cpp): make server-side prompt cache work by default (#9925)
Aligns LocalAI's llama-cpp gRPC backend with upstream's auto-on prompt
cache path so repeated system prompts (agents, OpenAI/Anthropic-compatible
CLIs, coding assistants) skip prefill on subsequent calls without any
YAML changes. Reported in #9921.

Upstream's server enables `kv_unified=true` (and bumps `n_parallel` to 4)
when slot count is auto, which unlocks `cache_idle_slots`. LocalAI
hardcodes `n_parallel=1` and so far also hardcoded `kv_unified=false`,
which silently force-disables idle-slot saving at server init. The host
prompt cache was allocated but never written across requests.

Changes in backend/cpp/llama-cpp/grpc-server.cpp:
- params.kv_unified: false -> true (single-slot path now benefits from
  the prompt cache; users can opt out with `kv_unified:false`)
- params.n_ctx_checkpoints: 8 -> 32 (match upstream default)
- params.cache_idle_slots = true initialized explicitly (upstream default)
- params.checkpoint_every_nt = 8192 initialized explicitly (upstream default)
- New option parsers: cache_idle_slots / idle_slots_cache,
  checkpoint_every_nt / checkpoint_every_n_tokens

Docs:
- features/text-generation.md: fix misleading `cache_ram` description
  (it's the host-side prompt cache, not the KV cache), document the
  kv_unified + cache_ram + cache_idle_slots interaction, add rows for
  the two newly-exposed options, and add a worked example for the
  agent/CLI workload from the issue.
- advanced/model-configuration.md: mark the legacy `prompt_cache_path`
  / `prompt_cache_all` / `prompt_cache_ro` YAML fields as unused by the
  llama-cpp gRPC backend (they target upstream's CLI completion tool
  and are not consumed by grpc-server.cpp) and point readers at the
  new prompt-cache explainer.

Closes #9921

Requirement

In this project, the Docsy theme component is pulled in as a Hugo module, together with other module dependencies:

$ hugo mod graph

If you want to do SCSS edits and want to publish these, you need to install PostCSS

npm install

Running the website locally

Building and running the site locally requires a recent extended version of Hugo. You can find out more about how to install Hugo for your environment in our Getting started guide.

Once you've made your working copy of the site repo, from the repo root folder, run:

hugo server

Running a container locally

You can run docsy-example inside a Docker container, the container runs with a volume bound to the docsy-example folder. This approach doesn't require you to install any dependencies other than Docker Desktop on Windows and Mac, and Docker Compose on Linux.

  1. Build the docker image

    docker-compose build
    
  2. Run the built image

    docker-compose up
    

    NOTE: You can run both commands at once with docker-compose up --build.

  3. Verify that the service is working.

    Open your web browser and type http://localhost:1313 in your navigation bar, This opens a local instance of the docsy-example homepage. You can now make changes to the docsy example and those changes will immediately show up in your browser after you save.

Cleanup

To stop Docker Compose, on your terminal window, press Ctrl + C.

To remove the produced images run:

docker-compose rm

For more information see the Docker Compose documentation.

Troubleshooting

As you run the website locally, you may run into the following error:

➜ hugo server

INFO 2021/01/21 21:07:55 Using config file: 
Building sites … INFO 2021/01/21 21:07:55 syncing static files to /

Error: Error building site: TOCSS: failed to transform "scss/main.scss" (text/x-scss): resource "scss/scss/main.scss_9fadf33d895a46083cdd64396b57ef68" not found in file cache

This error occurs if you have not installed the extended version of Hugo. See this section of the user guide for instructions on how to install Hugo.

Or you may encounter the following error:

➜ hugo server

Error: failed to download modules: binary with name "go" not found

This error occurs if you have not installed the go programming language on your system. See this section of the user guide for instructions on how to install go.
