Metadata for chat and embeddings models

Fields

model_name: String

model_alias: String

log_prompts: bool

prompt_template: PromptTemplateType

log_enable: bool

debug_log: bool

embeddings: bool

n_predict: i32

Number of tokens to predict, -1 = infinity, -2 = until context filled. Defaults to -1.

reverse_prompt: Option<String>

Halt generation at PROMPT, return control in interactive mode.

mmproj: Option<String>

path to the multimodal projector file for llava

image: Option<String>

Path to the image file for llava

n_gpu_layers: u64

main_gpu: Option<u64>

The main GPU to use. Defaults to None.

tensor_split: Option<String>

How split tensors should be distributed accross GPUs. If None the model is not split; otherwise, a comma-separated list of non-negative values, e.g., “3,2” presents 60% of the data to GPU 0 and 40% to GPU 1. Defaults to None.

use_mmap: Option<bool>

Whether to use memory-mapped files for the model. Defaults to true.

split_mode: String

How to split the model across multiple GPUs. Possible values:

• none: use one GPU only
• layer: split layers and KV across GPUs (default)
• row: split rows across GPUs

ctx_size: u64

Size of the prompt context. 0 means loaded from model. Defaults to 4096.

batch_size: u64

Logical maximum batch size. Defaults to 2048.

ubatch_size: u64

Physical maximum batch size. Defaults to 512.

threads: u64

Number of threads to use during generation. Defaults to 2.

temperature: f64

Adjust the randomness of the generated text. Between 0.0 and 2.0. Defaults to 0.8.

top_p: f64

Top-p sampling. Between 0.0 and 1.0. Defaults to 0.9.

repeat_penalty: f64

Penalize repeat sequence of tokens. Defaults to 1.0.

presence_penalty: f64

Repeat alpha presence penalty. Defaults to 0.0.

frequency_penalty: f64

Repeat alpha frequency penalty. Defaults to 0.0.

grammar: String

BNF-like grammar to constrain generations (see samples in grammars/ dir). Defaults to empty string.

json_schema: Option<String>

JSON schema to constrain generations (https://json-schema.org/), e.g. {} for any JSON object. For schemas w/ external $refs, use –grammar + example/json_schema_to_grammar.py instead.

include_usage: bool

Whether to include usage in the stream response. Defaults to false.
