MONET Captions Dataset

MONET (Massive, Open, Non-redundant and Enriched Text-to-image dataset) is a large-scale, curated image-text dataset designed for training text-to-image (T2I) systems.

• jasperai/monet

This repository provides an enriched, concise, and multi-VLM-synthesized caption dataset derived from MONET to improve training efficiency and text description quality.

🛠️ Dataset Construction

The dataset is built upon a sample of ~100,000 images sourced from agentlans/jasperai-monet-sample.

Processing Pipeline

1. Multi-VLM Caption Extraction: Individual captions were generated using a variety of vision-language models (e.g., Florence-2-Large, Gemini 2.5 Flash Lite, InternVL-3-8B, and ShareGPT4V-7B).
2. Qwen3.5-9B Merging: The individual model captions were aggregated and merged using Qwen3.5-9B to produce a single, highly detailed yet concise caption.

Merging Prompt

Merge the captions below into one short, accurate caption.

Rules:

* Include the key details from all captions.
* Remove repeated or unnecessary information.
* Keep the result clear, natural, and concise.
* Do not add or guess information.
* Output only the final caption.

📂 Data Structure & Splits

The dataset is split into Train (80%) and Test (20%) sets.

Schema

• __key__: The unique ID. Matches the ID in the original dataset for retrieving the actual image.
• caption_<model_name>: Individual raw captions generated by respective VLMs.
• caption: The final synthesized, merged caption.

  "caption_gemini-2.5-flash-lite": "The image is a poster for an event titled \"EVERY SHINY THING: A CREATIVE REIMAGINING OF JONI MITCHELL'S GROUND-BREAKING MUSIC\". The poster features a stylized illustration against a dark blue background. In the upper part, a bright yellow sun-like shape is adorned with yellow stars of various sizes. Within this yellow shape, the title \"EVERY SHINY THING\" is written in large, bold, black letters. Arched around the top and right side of the sun are the phrases \"A CREATIVE REIMAGINING OF\" and \"GROUND-BREAKING MUSIC\" in smaller, black text. Below the title, the name \"JONI MITCHELL'S\" is also written in black. Dominating the lower left and central portion of the poster is a silhouette of a woman with very long, flowing, bright yellow hair. She is wearing a light blue garment and her left arm is raised, with her hand reaching upwards towards the sun. Her hair is depicted as wavy ribbons, and on these ribbons, the names of performers are listed in black, hand-written style text. These names, from top to bottom, are: ANDREA BUNCH, EMILY THOMPSON, ASHLEY KUSHNER, RANDY MORRIS, GREG NERGAARD, ROGER REUPERT, JANET CRAMER, JOHN BOWES, and JIM BARBICK. At the very bottom of the poster, event details are provided: \"Sun, April 26 - 7PM $20\" and \"old town school of folk music\". The overall style is illustrative and artistic, with bold colors and a whimsical, free-hand aesthetic.",

⚠️ Limitations

• Dataset Bias: MONET's content leans predominantly toward safe-for-work (SFW) photos.
• VLM Limitations: Captions are dependent on the inherent text and vision recognition capabilities of the underlying models.
• Synthesis Biases: Potential stylistic or structural biases introduced during the Qwen3.5 text-merging process.
• Verification: Merged captions have not been exhaustively cross-checked manually against the original images.
