## 🆠Why List-3.0-Ultra-Coder?
**List-3.0-Ultra-Coder** is not just an incremental update — it's a generational leap. Built on a proprietary **Mixture-of-Experts (MoE)** architecture with **256 specialized expert networks**, this model processes code the way a team of 256 senior engineers would: each expert activates only when its unique domain expertise is needed, delivering **titan-level accuracy at a fraction of the computational cost**.
> **"We didn't build another coding assistant. We built the engineer that engineers wish they had."**

## 🚀 Get Started in 60 Seconds
### Option 1: List Coder IDE (Recommended)
The fastest way to experience **List-3.0-Ultra-Coder** at full power.
1. **Download** the List Coder IDE from **[list-coder.com](https://list-coder.com/download)**
2. **Sign in** with your account
3. **Start coding** — the model is pre-configured and ready
> 💡 The IDE provides native integration with all List models, including real-time code completion, multi-file refactoring, and architectural guidance.
### Option 3: Local Deployment (Advanced)
```python
from transformers import AutoModelForCausalLM, AutoTokenizer
model_name = "List-cloud/List-3.0-Ultra-Coder-Brain"
tokenizer = AutoTokenizer.from_pretrained(model_name, trust_remote_code=True)
model = AutoModelForCausalLM.from_pretrained(
model_name,
device_map="auto",
trust_remote_code=True,
torch_dtype="auto"
)
prompt = "Implement a lock-free concurrent hash map in Rust with work-stealing."
inputs = tokenizer(prompt, return_tensors="pt").to(model.device)
outputs = model.generate(**inputs, max_new_tokens=4096)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))
```
> âš ï¸ Local deployment requires **8x A100 80GB** or equivalent. For most users, the **API** or **IDE** is recommended.
