Param	Description
`model_type`	The architecture to load the model as. Supported values: `mistral`, `gemma`, `mixtral`, `llama`, `phi2`, `phi3`, `qwen2`, `gemma2`, `starcoder2`, `phi3.5moe`, `deepseekv2`, `deepseek`
`tools`	Which tools should be made available to the model. Set to `auto` to use all available tools.
`system_prompt`	An additional system prompt used for all chat completions to this model.
`chat_template`	Customizes the transformation of OpenAI chat messages into a character stream for the model. See Overriding the Chat Template.

See Large Language Models for additional configuration options.

`files` (optional)

The files field specifies additional files required by the model, such as tokenizer, configuration, and other files.

Examples

Loading a GGML Model

Example: Loading a SafeTensor Model

Loading LLM from a directory

Note: The folder provided should contain all the expected files (see examples above).

Loading an ONNX Model

Loading a GGUF Model

Overriding the Chat Template

Chat templates convert the OpenAI compatible chat messages (see format) and other components of a request into a stream of characters for the language model. It follows Jinja3 templating syntax.

Further details on chat templates can be found here.

Templating Variables

messages: List of chat messages, in the OpenAI format.
add_generation_prompt: Boolean flag whether to add a generation prompt.
tools: List of callable tools, in the OpenAI format.

:::warning[Limitations]

The throughput, concurrency & latency of a locally hosted model will vary based on the underlying hardware and model size. Spice supports Apple metal and CUDA for accelerated inference.

title: 'Filesystem Hosted Models' description: 'Instructions for using models hosted on a filesystem with Spice.' sidebar_label: 'Filesystem' sidebar_position: 5

To use a model hosted on a filesystem, specify the path to the model file or folder in the from field:

Supported formats include GGUF, GGML, and SafeTensor for large language models (LLMs) and ONNX for traditional machine learning (ML) models.

Configuration

`from`

An absolute or relative path to the model file or folder:
