Implementation:Open compass VLMEvalKit OmniLMM12B

Field	Value
source	VLMEvalKit
domain	Vision, Model_Architecture

Overview

VLM adapter for the OmniLMM-12B model enabling benchmark evaluation in VLMEvalKit.

Description

OmniLMM12B inherits from BaseModel and wraps the OmniLMM-12B model for use within the VLMEvalKit evaluation framework. It initializes the model and tokenizer/processor from a HuggingFace model path (default: model_path, root (required)) and provides the generate_inner method for inference. Uses a custom model initialization function with OmniLMMForCausalLM and separate image processor.

Usage

Register in vlmeval/config.py via supported_VLM and invoke through the standard evaluation pipeline.

Code Reference

Source: vlmeval/vlm/omnilmm.py, Lines: L1-183
Import: from vlmeval.vlm.omnilmm import OmniLMM12B

Signature:

class OmniLMM12B(BaseModel):
    INSTALL_REQ = True
    INTERLEAVE = False
    def __init__(self, model_path='model_path, root (required)', **kwargs): ...
    def generate_inner(self, message, dataset=None): ...

I/O Contract

Direction	Description
Inputs	message — list of dicts with type (text/image) and value; dataset — optional dataset name for custom prompting
Outputs	generate_inner() returns str (model response text)

Usage Examples

from vlmeval.vlm.omnilmm import OmniLMM12B
model = OmniLMM12B(model_path='path/to/model')
response = model.generate_inner(message)
