# JanusCoder-8B

## Introduction
|
| 12 |
+
|
| 13 |
+
We introduce JanusCoder and JanusCoderV, a suite of open-source foundational models designed to establish a unified visual-programmatic interface for code intelligence.
|
| 14 |
+
This model suite is built upon open-source language models (such as Qwen3-8B and 14B) and multimodal models (such as Qwen2.5-VL and InternVL3.5-8B). The JanusCoder series is trained on JANUSCODE-800K—the largest multimodal code corpus to date, generated by an innovative synthesis toolkit, covering everything from standard charts to complex interactive Web UIs and code-driven animations.
|
| 15 |
+
This enables the models to uniformly handle diverse visual-programmatic tasks, such as generating code from textual instructions, visual inputs, or a combination of both, rather than building specialized models for isolated tasks. JanusCoder excels at flexible content generation (like data visualizations and interactive front-ends) as well as precise, program-driven editing of visual effects and complex animation construction.

**Transformers**
|
| 41 |
+
|
| 42 |
+
The following provides demo code illustrating how to generate text using JanusCoder-8B.
|
| 43 |
+
|
| 44 |
+
> Please use transformers >= 4.55.0 to ensure the model works normally.
|
| 45 |
+
|
| 46 |
+
```python
|
| 47 |
+
from transformers import AutoTokenizer, AutoModelForCausalLM
|
| 48 |
+
import torch
|
| 49 |
+
|
| 50 |
+
model_name = "internlm/JanusCoder-8B"
|
| 51 |
+
tokenizer = AutoTokenizer.from_pretrained(model_name)
|
| 52 |
+
model = AutoModelForCausalLM.from_pretrained(model_name, device_map="auto", torch_dtype="auto")
|
| 53 |
+
|
| 54 |
+
messages = [
|
| 55 |
+
{
|
| 56 |
+
"role": "user",
|
| 57 |
+
"content": [
|
| 58 |
+
{"type": "text", "text": "Create a line plot that illustrates function y=x."},
|
| 59 |
+
],
|
| 60 |
+
}
|
| 61 |
+
]
|
| 62 |
+
|
| 63 |
+
inputs = tokenizer.apply_chat_template(messages, add_generation_prompt=True, tokenize=True, return_dict=True, return_tensors="pt").to(model.device, dtype=torch.bfloat16)
|
| 64 |
+
|
| 65 |
+
generate_ids = model.generate(**inputs, max_new_tokens=32768)
|
| 66 |
+
decoded_output = processor.decode(generate_ids[0, inputs["input_ids"].shape[1] :], skip_special_tokens=True)
|
| 67 |
+
print(decoded_output)
