Download GGML Model

External tool documentation for the download-ggml-model.sh shell script that retrieves and converts GPT-2 model weights into GGML format.

API

download-ggml-model.sh <model_size>

Source: examples/gpt-2/download-ggml-model.sh:L1-70
Repository: https://github.com/ggml-org/ggml
Language: Shell/Bash

Parameters

Parameter	Description	Accepted Values
`model_size`	Size variant of the GPT-2 model to download	`"117M"`, `"345M"`, `"774M"`, `"1558M"`

Behavior

The script uses wget or curl (whichever is available) to download GPT-2 model files from OpenAI/HuggingFace hosting. The following files are retrieved:

encoder.json — Byte-pair encoding tokenizer vocabulary.
hparams.json — Model hyperparameters (layer count, embedding dimension, etc.).
Model checkpoint — The raw weight tensors for the selected size variant.

After downloading, the script invokes a Python conversion step that transforms the checkpoint into GGML binary format.

Output

File: ggml-model.bin
Format: Legacy GGML binary format
Magic number: 0x67676d6c

The resulting ggml-model.bin file can be loaded directly by GGML-based inference examples (e.g., the GPT-2 example program).

Dependencies

wget or curl — For downloading files from remote servers.
Python — Required for the format conversion step that produces the final .bin file.

Example Usage

# Download the smallest GPT-2 variant (117M parameters)
./download-ggml-model.sh 117M

# Download the largest GPT-2 variant (1558M parameters)
./download-ggml-model.sh 1558M
