pipe = pipeline("image-text-to-text", model="CosmossG/COSMOS-9B-V1")
messages = [
    {
        "role": "user",
        "content": [
            {"type": "image", "url": "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/p-blog/candy.JPG"},
            {"type": "text", "text": "What animal is on the candy?"}
        ]
    },
]
pipe(text=messages)

# Load model directly
from transformers import AutoProcessor, AutoModelForMultimodalLM

processor = AutoProcessor.from_pretrained("CosmossG/COSMOS-9B-V1")
model = AutoModelForMultimodalLM.from_pretrained("CosmossG/COSMOS-9B-V1", device_map="auto")
messages = [
    {
        "role": "user",
        "content": [
            {"type": "image", "url": "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/p-blog/candy.JPG"},
            {"type": "text", "text": "What animal is on the candy?"}
        ]
    },
]
inputs = processor.apply_chat_template(
	messages,
	add_generation_prompt=True,
	tokenize=True,
	return_dict=True,
	return_tensors="pt",
).to(model.device)

outputs = model.generate(**inputs, max_new_tokens=40)
print(processor.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

COSMOS 9B V1 (Base Merge)

COSMOS 9B V1 is a merged base model combining the advanced reasoning and massive context window of Qwythos-9B with the agentic coding capabilities of OmniCoder-9B.

Merge Details

Merge Method

This model was merged using a custom DARE-TIES implementation (50% density, 50% weight) to preserve the distinct specializations of both parent models.

Models Merged

[empero-ai/Qwythos-9B-Claude-Mythos-5-1M]: A full-parameter reasoning model post-trained on Claude Mythos traces with a 1,048,576-token context window (YaRN).
[Tesslate/OmniCoder-9B]: A coding agent model fine-tuned on 425,000+ curated agentic coding trajectories from Claude Opus 4.6.

Configuration

The merge was anchored to the Qwythos-9B base to strictly preserve the YaRN 1M context window, native function calling, and the Qwen3.5 hybrid architecture (Gated Delta Networks).

Intended Use

This is a base merge intended for further fine-tuning, specifically for educational purposes, programming instruction (C/C++), and Portuguese language specialization.
