Args:

n_ctx: Maximum context size.
|
||||
n_batch: Maximum number of prompt tokens to batch together when calling llama_eval.

main_gpu: Main GPU to use.
|

tensor_split: Optional list of floats to split the model across multiple GPUs. If None, the model is not split.

rope_freq_base: Base frequency for rope sampling.
|

rope_freq_scale: Scale factor for rope sampling.
|

low_vram: Use low VRAM mode.

mul_mat_q: if true, use experimental mul_mat_q kernels
|

f16_kv: Use half-precision for key/value cache.
|

logits_all: Return logits for all tokens, not just the last token.
