What does this PR do?

Conversion cmd-line for mistralai/Mistral-Small-3.1-24B-Instruct-2503:

optimum-cli export openvino -m mistralai/Mistral-Small-3.1-24B-Instruct-2503 ./Mistral-Small-3.1-24B --task image-text-to-text

Inference of mistralai/Mistral-Small-3.1-24B-Instruct-2503 using OpenVINO backend:

from transformers import AutoTokenizer, AutoProcessor
from transformers.image_utils import load_image
from huggingface_hub import hf_hub_download
from optimum.intel.openvino import OVModelForVisualCausalLM


model_dir = "./Mistral-Small-3.1-24B"

tokenizer = AutoTokenizer.from_pretrained(model_dir)
processor = AutoProcessor.from_pretrained(model_dir)
model = OVModelForVisualCausalLM.from_pretrained(model_dir)

# Prepare image input
image_path = hf_hub_download(
                repo_id="raushan-testing-hf/images_test",
                filename="australia.jpg",
                repo_type="dataset",
        )
image_input = load_image(image_path)
question = "Describe this image."
inputs = model.preprocess_inputs(processor=processor, text=question, image=image_input)

# Run inference
output_ids = model.generate(**inputs, max_new_tokens=10)
output_text = tokenizer.decode(output_ids[0])

print(output_text)

Hi @popovaan,

Could you please take a look at my PR?

Thank you!

Please add tests to the PR and use a local path for now, until we have a published tiny model.

rkazants

please add tests and create tiny model for it

Hi @popovaan and @rkazants,

I've added the tests and created a tiny model locally for now.

Here is the script I used to create the tiny model:

import os
from transformers import (
    AutoConfig,
    AutoModelForImageTextToText,
    AutoProcessor,
    AutoTokenizer,
)

model_id = "mistralai/Mistral-Small-3.1-24B-Instruct-2503"
config = AutoConfig.from_pretrained(model_id)

config.text_config.num_hidden_layers = 2
config.text_config.hidden_size = 8
config.text_config.intermediate_size = 64
config.text_config.num_attention_heads = 8
config.text_config.num_key_value_heads = 4
config.text_config.head_dim = 32

config.vision_config.num_hidden_layers = 2
config.vision_config.hidden_size = 128
config.vision_config.intermediate_size = 64
config.vision_config.num_attention_heads = 4
config.vision_config.head_dim = 32

model = AutoModelForImageTextToText.from_config(config)
tokenizer = AutoTokenizer.from_pretrained(model_id)
processor = AutoProcessor.from_pretrained(model_id)

output_dir = "./tiny-random-mistral3"
os.makedirs(output_dir, exist_ok=True)
model.save_pretrained(output_dir)
tokenizer.save_pretrained(output_dir)
processor.save_pretrained(output_dir)

I’d appreciate it if you could review the updates.

why not inherit fro DummyLLavaMultiModalProjectorInputGenerator and just add the spatial_merge_size attribute ? num_merged_patches can be inferred from self.num_patches no ? Also here the resulting input shape will not vary depending on batch_size could you extend on why ?

Good points! I'll refactor to inherit from DummyLLavaMultiModalProjectorInputGenerator and derive num_merged_patches from self.num_patches.
Regarding batch_size: in the original transformers implementation, Mistral3PatchMerger.forward() concatenates patches from all images via torch.cat(permuted_tensor, dim=0) into a flat 2D tensor [total_merged_patches, dim], because each image can have different spatial dimensions and thus produce a different number of merged patches — so they can't form a uniform batch axis. Since the cycle block runs in PyTorch at runtime, the projector submodel receives this already-flattened 2D input, which is why batch_size doesn't appear in the shape.

+    def inputs(self) -> Dict[str, Dict[int, str]]:
+        return {"image_features": {0: "num_patches"}}


why not :

Suggested change

return {"image_features": {0: "num_patches"}}

return {"image_features": {0: "batch_size", 1: "sequence_length"}}

This is related to the batch_size discussion above — since the cycle block flattens all images' patches into a single 2D tensor [total_merged_patches, dim], the projector input has only one dynamic dimension. So {0: "num_patches"} reflects the actual runtime shape.
