 # llama-swap

-![llama-swap header image](header.jpeg)
+llama-swap is a light weight, transparent proxy server that provides automatic model swapping to llama.cpp's server.

-# Introduction
-llama-swap is an OpenAI API compatible server that gives you complete control over how you use your hardware. It automatically swaps to the configuration of your choice for serving a model. Since [llama.cpp's server](https://github.com/ggerganov/llama.cpp/tree/master/examples/server) can't swap models, let's swap the server instead!
+Written in golang, it is very easy to install (single binary with no dependancies) and configure (single yaml file). To get started, download a pre-built binary or use the provided docker images.

-Features:
+## Features:

 - ✅ Easy to deploy: single binary with no dependencies
 - ✅ Easy to config: single yaml file
 - ✅ On-demand model switching
+- ✅ OpenAI API supported endpoints:
+  - `v1/completions`
+  - `v1/chat/completions`
+  - `v1/embeddings`
+  - `v1/rerank`
+  - `v1/audio/speech` ([#36](https://github.com/mostlygeek/llama-swap/issues/36))
+  - `v1/audio/transcriptions` ([docs](https://github.com/mostlygeek/llama-swap/issues/41#issuecomment-2722637867))
+- ✅ llama-swap custom API endpoints
+  - `/log` - remote log monitoring
+  - `/upstream/:model_id` - direct access to upstream HTTP server ([demo](https://github.com/mostlygeek/llama-swap/pull/31))
+  - `/unload` - manually unload running models ([#58](https://github.com/mostlygeek/llama-swap/issues/58))
+  - `/running` - list currently running models ([#61](https://github.com/mostlygeek/llama-swap/issues/61))
+- ✅ Run multiple models at once with `profiles` ([docs](https://github.com/mostlygeek/llama-swap/issues/53#issuecomment-2660761741))
+- ✅ Automatic unloading of models after timeout by setting a `ttl`
+- ✅ Use any local OpenAI compatible server (llama.cpp, vllm, tabbyAPI, etc)
+- ✅ Docker and Podman support
 - ✅ Full control over server settings per model
- ✅ OpenAI API support (`v1/completions` and `v1/chat/completions`)
- ✅ Multiple GPU support
- ✅ Run multiple models at once with `profiles`
- ✅ Remote log monitoring at `/log`
- ✅ Automatic unloading of models from GPUs after timeout
- ✅ Use any local OpenAI compatible server (llama.cpp, vllm, tabblyAPI, etc)
- ✅ Direct access to upstream HTTP server via `/upstream/:model_id` ([demo](https://github.com/mostlygeek/llama-swap/pull/31))

-## Releases
+## How does llama-swap work?

-Builds for Linux and OSX are available on the [Releases](https://github.com/mostlygeek/llama-swap/releases) page.
+When a request is made to an OpenAI compatible endpoint, lama-swap will extract the `model` value and load the appropriate server configuration to serve it. If the wrong upstream server is running, it will be replaced with the correct one. This is where the "swap" part comes in. The upstream server is automatically swapped to the correct one to serve the request.

-### Building from source
-
-1. Install golang for your system
-1. `git clone git@github.com:mostlygeek/llama-swap.git`
-1. `make clean all`
-1. Binaries will be in `build/` subdirectory
+In the most basic configuration llama-swap handles one model at a time. For more advanced use cases, the `profiles` feature can load multiple models at the same time. You have complete control over how your system resources are used.

 ## config.yaml

 llama-swap's configuration is purposefully simple.

+```yaml
+models:
+  "qwen2.5":

+### Use Case Examples

 - [config.example.yaml](config.example.yaml) includes example for supporting `v1/embeddings` and `v1/rerank` endpoints
 - [Speculative Decoding](examples/speculative-decoding/README.md) - using a small draft model can increase inference speeds from 20% to 40%. This example includes a configurations Qwen2.5-Coder-32B (2.5x increase) and Llama-3.1-70B (1.4x increase) in the best cases.
 - [Optimizing Code Generation](examples/benchmark-snakegame/README.md) - find the optimal settings for your machine. This example demonstrates defining multiple configurations and testing which one is fastest.
+- [Restart on Config Change](examples/restart-on-config-change/README.md) - automatically restart llama-swap when trying out different configurations.

+
+Docker is the quickest way to try out llama-swap:
+
+```
+# use CPU inference
+$ docker run -it --rm -p 9292:8080 ghcr.io/mostlygeek/llama-swap:cpu
+
+
+# qwen2.5 0.5B
+$ curl -s http://localhost:9292/v1/chat/completions \

+    -H "Authorization: Bearer no-key" \
+    -d '{"model":"qwen2.5","messages": [{"role": "user","content": "tell me a joke"}]}' | \
+    jq -r '.choices[0].message.content'
+

+<summary>Docker images are nightly ...</summary>
+
+They include:
+
+- `ghcr.io/mostlygeek/llama-swap:cpu`
+- `ghcr.io/mostlygeek/llama-swap:cuda`
+- `ghcr.io/mostlygeek/llama-swap:intel`
+- `ghcr.io/mostlygeek/llama-swap:vulkan`
+- ROCm disabled until fixed in llama.cpp container
+
+Specific versions are also available and are tagged with the llama-swap, architecture and llama.cpp versions. For example: `ghcr.io/mostlygeek/llama-swap:v89-cuda-b4716`
+
+Beyond the demo you will likely want to run the containers with your downloaded models and custom configuration.
+
+```
+$ docker run -it --rm --runtime nvidia -p 9292:8080 \
+  -v /path/to/models:/models \
+  -v /path/to/custom/config.yaml:/app/config.yaml \

+```
+
+</details>
+
+## Bare metal Install ([download](https://github.com/mostlygeek/llama-swap/releases))
+
+Pre-built binaries are available for Linux, FreeBSD and Darwin (OSX). These are automatically published and are likely a few hours ahead of the docker releases. The baremetal install works with any OpenAI compatible server, not just llama-server.

 1. Create a configuration file, see [config.example.yaml](config.example.yaml)
 1. Download a [release](https://github.com/mostlygeek/llama-swap/releases) appropriate for your OS and architecture.
-    * _Note: Windows currently untested._
 1. Run the binary with `llama-swap --config path/to/config.yaml`

+### Building from source
+
+1. Install golang for your system
+1. `git clone git@github.com:mostlygeek/llama-swap.git`
+1. `make clean all`
+1. Binaries will be in `build/` subdirectory

+## Do I need to use llama.cpp's server (llama-server)?
+
+Any OpenAI compatible server would work. llama-swap was originally designed for llama-server and it is the best supported.
+
+For Python based inference servers like vllm or tabbyAPI it is recommended to run them via podman or docker. This provides clean environment isolation as well as responding correctly to `SIGTERM` signals to shutdown.

If no `Access-Control-Request-Headers` were sent, then send back a default set - set `Access-Control-Max-Age: 86400` to that may improve performance - Add CORS tests to the proxy-manager	2025-03-25 15:24:43 -07:00

Benson Wong	b3d331da0d	Properly strip profile name slug from models fixes (#62 ) The profile slug in a model name, `profile:model`, is specific to llama-swap. This strips `profile:` out of the model name request so upstreams that expect just `model` work and do not require knowing about the profile slug.	2025-03-09 12:41:52 -07:00

Benson Wong	eab9795bcc	remove panic() when cmd or process is nil	2025-02-07 14:00:32 -08:00
Benson Wong	09bdd86b54	Improve shutdown behaviour (#47 ) (#49 ) Introduce `Process.Shutdown()` and `ProxyManager.Shutdown()`. These two function required a lot of internal process state management refactoring. A key benefit is that `Process.start()` is now interruptable. When `Shutdown()` is called it will break the long health check loop. State management within Process is also improved. Added `starting`, `stopping` and `shutdown` states. Additionally, introduced a simple finite state machine to manage transitions.	2025-02-05 17:19:59 -08:00
Benson Wong	85cd74a51c	Improve process start and stop reliability (#38 ) Refactor Process.start()/Stop() logic (#38) - remove cmd.Wait() call in start(). This seems to conflict with the one in .Stop(). Removing it eliminated no child errors - eliminate goroutines in .start() as it no longer required	2025-02-03 11:50:38 -08:00

Benson Wong	baeb0c4e7f	Add cmd_stop configuration to better support docker (#35 ) Add `cmd_stop` to model configuration to run a command instead of sending a SIGTERM to shutdown a process before swapping.	2025-01-30 16:59:57 -08:00
Benson Wong	2833517eef	Improve handling of process that do not handle SIGTERM (#38 ) - Process TTL goroutine did not have a return after .Stop() - Improve logging - Add test TestProcess_LowTTLValue to measure SIGTERM error rate	2025-01-20 14:39:52 -08:00
Benson Wong	abdc2bfdb3	Fix panic when requesting non-members of profiles A panic occurs when a request for an invalid profile:model pair is made. The edge case is that the profile exists and the model exists but they're not configured as a pair. This adds an additional check to make sure the profile:model pair is valid before attempting to swap the model.	2025-01-16 12:06:38 -08:00
