Model Card

Title

Suggest a title and description for any text.

On-device titles and descriptions: a short factual title and a one- to two-sentence description for any passage of text.

—SDKs, install and examples: https://github.com/Desert-Ant-Labs/desert-ant-core/blob/main/docs/models/title.md

Install

Swift (requirements)

swift

.package(url: "https://github.com/Desert-Ant-Labs/desert-ant-core.git", from: "3.6.0",
        traits: ["MLX"])

Then add the Title product to your target. The MLX trait is required: without it the module compiles as a stub.

Get a title and a one or two sentence description for any passage of text, on device.

Fine-tuned on transcript clips, but it works on any prose. The register is deliberately plain, with no emoji, no hashtags and no clickbait, and a description is meant to identify this passage rather than its topic.

Files

An MLX model directory. Load the folder, not a single file.

File	Contents
`model.safetensors`	6-bit quantized weights
`model.safetensors.index.json`	shard index; present even for one shard, because the loader reads it
`config.json`	architecture and quantization config
`generation_config.json`	decode defaults
`tokenizer.json`, `tokenizer_config.json`	byte-level BPE with merges
`chat_template.jinja`	the chat template the fine-tune was trained against

The chat template is not incidental. A different template is a different task to this model.

The prompt

The model was fine-tuned against one specific instruction, and a paraphrase is a different task to it. It lives in Titles.prompt in the SDK; use that wording. The reply is two labelled lines:

TITLE: <3-8 words, no final punctuation>
DESC: <1-2 sentences>

Parse tolerantly. A card model that drifts off format should degrade to a usable title rather than throw.

Apple only

MLX runs on Apple silicon and nowhere else, so there is no Android, Linux or Windows artifact here and no manifest promising one. A Core ML export exists in the training repository and is kept as evidence rather than as a candidate: on short autoregressive decode the Neural Engine is bandwidth-bound, and the Core ML arm lost on first token, throughput, load time and resident memory.

Status

Internal testing, and less settled than that phrase usually implies. This card carries no quality figures: no independent review has been completed, and a known open issue is that the model sometimes opens a description with a stock phrase its own instruction forbids. Treat the output as needing a read before it reaches a user.

Built on

—`ibm-granite/granite-4.0-350m` , the base model this is fine-tuned from.
