vittle-7b-F

Vittle-7B (F) weight

Vittle (F) is the fixed-prior variant of Vittle (NeurIPS 2025), a VLM instruction tuning framework that improves robustness to distribution shifts via variational information bottleneck.

• Paper: arXiv:2505.13946
• Code: deeplearning-wisc/vittle

Usage

import torch
from vittle.model.language_model.vittle_llama import VittleLlamaForCausalLM
from transformers import AutoTokenizer

model = VittleLlamaForCausalLM.from_pretrained(
    "changdae/vittle-7b-F",
    torch_dtype=torch.bfloat16,
    device_map="cuda:0",
)
tokenizer = AutoTokenizer.from_pretrained("changdae/vittle-7b-F", use_fast=False)

Refer to the evaluation guide for full inference instructions.
