Introduction
Diagram of Ferret Model.
Secret Contributions:
- Ferret Model – Hybrid Region Representation + Spatial-aware Visual Sampler make it possible for fine-grained and open-vocabulary referring and grounding in MLLM.
- GRIT Dataset (~ 1.1 M) – A Large-scale, Hierarchical, Robust ground-and-refer guideline tuning dataset.
- Ferret-Bench – A multimodal examination standard that collectively needs Referring/Grounding, Semantics, Knowledge, and Reasoning.
Release
- [12/14] We launched the checkpoints(7B, 13B).
- [10/30] We launched the code of FERRET design and Ferret-Bench.

FERRET is trained on 8 A100 GPUs with 80GB memory. To train on less GPUs, you can decrease the per_device_train_batch_size and increase the gradient_accumulation_steps appropriately. Constantly keep the international batch size the exact same: per_device_train_batch_size x gradient_accumulation_steps x num_gpus.
Hyperparameters
We utilize a comparable set of hyperparameters as LLaVA(Vicuna) in finetuning.

Before you begin, prepare our base design Vicuna, which is an instruction-tuned chatbot. Please download its weights following the directions here. Vicuna v1.3 is utilized in FERRET.
Download LLaVA’s first-stage pre-trained projector weight (7B, 13B).
FERRET Training
The scripts are offered (7B, 13B).
Examination
Please see this doc for the information.
Checkpoints
We drew out the delta in between our pre-trained design and Vicuna. Please initially download weights of Vicuna following the previous direction. Download our ready offsets of weights: 7B, 13B utilizing wget or curl, and unzip the downloaded offsets. Use the balanced out to the Vicuna’s weight by running the following script:
# 7B python3 -m ferret.model.apply _ delta — base./ model/vicuna -7 b-v1-3 — target./ model/ferret -7 b-v1-3 — delta path/to/ferret -7 b-delta # 13B python3 -m ferret.model.apply _ delta — base./ model/vicuna -13 b-v1-3 — target./ model/ferret -13 b-v1-3 — delta path/to/ferret -13 b-delta
