-## API Access
+Developed by [Hanzo AI](https://hanzo.ai) and the [Zoo Labs Foundation](https://zoo.ngo).
 
-This model is served exclusively via the Hanzo AI API. Weight downloads are not available for this model tier.
+## Quick Start
 
 ```python
-from openai import OpenAI
-
-client = OpenAI(base_url="https://api.hanzo.ai/v1", api_key="YOUR_KEY")
-response = client.chat.completions.create(
-    model="zen4-coder-pro",
-    messages=[{"role": "user", "content": "Hello"}],
-)
-print(response.choices[0].message.content)
+from transformers import AutoModelForCausalLM, AutoTokenizer
+
+model_id = "zenlm/zen4-coder-pro"
+tokenizer = AutoTokenizer.from_pretrained(model_id)
+model = AutoModelForCausalLM.from_pretrained(model_id, torch_dtype="auto", device_map="auto")
+
+messages = [{"role": "user", "content": "Hello!"}]
+text = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
+inputs = tokenizer([text], return_tensors="pt").to(model.device)
+outputs = model.generate(**inputs, max_new_tokens=512)
+print(tokenizer.decode(outputs[0][inputs.input_ids.shape[1]:], skip_special_tokens=True))
+```
+
+## API Access
+
+```bash
+curl https://api.hanzo.ai/v1/chat/completions \
