+# JanusCoder-14B
+
+[💻Github Repo](https://github.com/InternLM/JanusCoder) • [🤗Model Collections](https://huggingface.co/collections/internlm/januscoder) • [📜Technical Report](https://www.arxiv.org/abs/2510.23538)
+
+## Introduction
+
+We introduce JanusCoder and JanusCoderV, a suite of open-source foundational models designed to establish a unified visual-programmatic interface for code intelligence.
+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.
+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.

+## Model Downloads
+
+| Model Name | Description | Download |
+| --- | --- | --- |
+| JanusCoder-8B | 8B text model based on Qwen3-8B. | 🤗 [Model](https://huggingface.co/internlm//JanusCoder-8B) |
+| 👉 **JanusCoder-14B** | 14B text model based on Qwen3-14B. | 🤗 [Model](https://huggingface.co/internlm//JanusCoder-14B) |

+## Performance
+
+We evaluate the JanusCoder model on various benchmarks that span code interlligence tasks on multiple PLs:
+
+| Model | JanusCoder-14B | Qwen3-14B | Qwen2.5-Coder-32B-Instruct | LLaMA3-8B-Instruct | GPT-4o |
+| --- | --- | --- | --- | --- | --- |

+| ArtifactsBench | 41.1 | 36.5 | 35.5 | 36.5 | 37.9 |
+| DTVBench (Manim) | 8.41 | 6.63 | 9.61 | 4.92 | 10.60 |
+| DTVBench (Wolfram) | 5.97 | 5.08 | 4.98 | 3.15 | 5.97 |
+
+## Quick Start
+
+**Transformers**
+
+The following provides demo code illustrating how to generate text using JanusCoder-14B.
+
+> Please use transformers >= 4.55.0 to ensure the model works normally.
+
+```python
+from transformers import AutoTokenizer, AutoModelForCausalLM
+import torch
+
+model_name = "internlm/JanusCoder-14B"
+tokenizer = AutoTokenizer.from_pretrained(model_name)
+model = AutoModelForCausalLM.from_pretrained(model_name, device_map="auto", torch_dtype="auto")
+
+messages = [
+    {
+        "role": "user",
+        "content": [
+            {"type": "text", "text": "Create a line plot that illustrates function y=x."},
+        ],
+    }
+]
+
+inputs = tokenizer.apply_chat_template(messages, add_generation_prompt=True, tokenize=True, return_dict=True, return_tensors="pt").to(model.device, dtype=torch.bfloat16)
+
+generate_ids = model.generate(**inputs, max_new_tokens=32768)
+decoded_output = processor.decode(generate_ids[0, inputs["input_ids"].shape[1] :], skip_special_tokens=True)
+print(decoded_output)
+```
