🚀 Next 4B (s320)

Türkiye’s First Vision-Language Model — Efficient, Multimodal, and Reasoning-Focused

📖 Overview

Next 4B is a 4-billion parameter multimodal Vision-Language Model (VLM) based on Gemma 3 , fine-tuned to handle both text and images efficiently. It is Türkiye’s first open-source vision-language model , designed for:

• Understanding and generating text and image descriptions .
• Efficient reasoning and context-aware multimodal outputs.
• Turkish support with multilingual capabilities.
• Low-resource deployment using 8-bit quantization for consumer-grade GPUs.

This model is ideal for researchers, developers, and organizations who need a high-performance multimodal AI capable of visual understanding, reasoning, and creative generation .

Our Next 1B and Next 4B models are leading to all of the tiny models in benchmarks.

Also, our Next Z1 model is leading to state-of-the-art models in some of the Benchmarks.

🚀 Installation & Usage

Use with vision:

from transformers import AutoTokenizer, AutoModelForCausalLM, AutoProcessor
from PIL import Image
import torch

model_id = "Lamapi/next-4b"

model = AutoModelForCausalLM.from_pretrained(model_id)
processor = AutoProcessor.from_pretrained(model_id) # For vision.
tokenizer = AutoTokenizer.from_pretrained(model_id)

# Read image
image = Image.open("image.jpg")

# Create a message in chat format
messages = [
  {"role": "system","content": [{"type": "text", "text": "You are Next-X1, a smart and concise AI assistant trained by Lamapi. Always respond in the user's language. Proudly made in Turkey."}]},

  {
      "role": "user","content": [{"type": "image", "image": image},
      {"type": "text", "text": "Who is in this image?"}
    ]
  }
]

# Prepare input with Tokenizer
prompt = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
inputs = processor(text=prompt, images=[image], return_tensors="pt")

# Output from the model
output = model.generate(**inputs, max_new_tokens=50)
print(tokenizer.decode(output[0], skip_special_tokens=True))

Who is in this image?

The image shows Mustafa Kemal Atatürk , the founder and first President of the Republic of Turkey.

Use without vision:

from transformers import AutoTokenizer, AutoModelForCausalLM
import torch

model_id = "Lamapi/next-4b"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(model_id)

# Chat message
messages = [
    {"role": "system", "content": "You are Next-X1, a smart and concise AI assistant trained by Lamapi. Always respond in the user's language. Proudly made in Turkey."},
    {"role": "user", "content": "Hello, how are you?"}
]

# Prepare input with Tokenizer
prompt = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
inputs = tokenizer(prompt, return_tensors="pt")

# Output from the model
output = model.generate(**inputs, max_new_tokens=50)
print(tokenizer.decode(output[0], skip_special_tokens=True))

🎯 Goals

1. Multimodal Intelligence: Understand and reason over images and text.
2. Efficiency: Run on modest GPUs using 8-bit quantization.
3. Accessibility: Open-source availability for research and applications.
4. Cultural Relevance: Optimized for Turkish language and context while remaining multilingual.
