}'Cosine-Beta-KD-Instance
A 1.7B multimodal LLM checkpoint distilled with Cosine-KD + Beta-KD (Instance-level uncertainty weighting),
built on top of MobileVLM with
MobileLLaMA-1.4B-Chat as
the language backbone.
This checkpoint corresponds to the Beta-KD (Instance) row of the model
zoo in Beta-KD: Uncertainty-Aware Knowledge Distillation for Multimodal Large
Language Models.
Model Details
| Item | Value |
|---|---|
| Architecture | MobileVLM (CLIP visual encoder + LDP projector + MobileLLaMA LLM) |
| Language model | MobileLLaMA 1.4B |
| Distillation losses | Cosine-KD (logit alignment) + Beta-KD instance-level uncertainty loss |
| Training step | checkpoint-18000 |
| Total params | ~1.7B |
| Precision | fp16 |
Evaluation
Evaluated on six standard multimodal benchmarks (no beam search, greedy decoding to match the chat-demo behavior).
| Method | LLM | MMEP | MMEA | GQA | VQAT | POPE | MMBdev | SQAI | Avg. |
|---|---|---|---|---|---|---|---|---|---|
| Cosine-KD baseline | MobileLLaMA 1.4B | 1308.4 | 65.4 | 59.9 | 52.2 | 84.6 | 57.1 | 61.3 | 63.4 |
| + Beta-KD (Task) | MobileLLaMA 1.4B | 1352.0 | 67.6 | 60.8 | 53.9 | 85.4 | 59.1 | 61.2 | 64.7 |
| + Beta-KD (Instance) (this model) | MobileLLaMA 1.4B | 1350.3 | 67.5 | 61.2 | 54.2 | 86.0 | 60.2 | 62.9 | 65.3 |
Usage
import torch
from transformers import AutoTokenizer, AutoModelForCausalLM
repo_id = "jsun39/Cosine-Beta-KD-Instance"
tokenizer = AutoTokenizer.from_pretrained(repo_id, trust_remote_code=True)
model = AutoModelForCausalLM.from_pretrained(
repo_id,
torch_dtype=torch.float16,
trust_remote_code=True,
).cuda()
For full inference (image + text), please follow the inference example in the Beta-KD repo — the visual encoder / projector loading, image preprocessing, and chat template are described there.
