Instructions to use ZarfixAI/ZarfixAICerdas1.0 with libraries, inference providers, notebooks, and local apps. Follow these links to get started.

Libraries

How to use ZarfixAI/ZarfixAICerdas1.0 with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

pipe = pipeline("text-generation", model="ZarfixAI/ZarfixAICerdas1.0")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("ZarfixAI/ZarfixAICerdas1.0")
model = AutoModelForCausalLM.from_pretrained("ZarfixAI/ZarfixAICerdas1.0", device_map="auto")
messages = [
    {"role": "user", "content": "Who are you?"},
]
inputs = tokenizer.apply_chat_template(
	messages,
	add_generation_prompt=True,
	tokenize=True,
	return_dict=True,
	return_tensors="pt",
).to(model.device)

outputs = model.generate(**inputs, max_new_tokens=40)
print(tokenizer.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

-# ZarfixAICerdas1.0
-**Summary:** ZarfixAICerdas1.0 is a lightweight 4B parameter language model focused on fast, low-cost inference.
-> Derived from janhq/Jan-v1-4B. Original work is licensed under Apache-2.0 (see `LICENSE`).
-## Quickstart
 ```python
 from transformers import AutoTokenizer, AutoModelForCausalLM
-tok = AutoTokenizer.from_pretrained("ZarfixAI/ZarfixAICerdas1.0")
-m = AutoModelForCausalLM.from_pretrained("ZarfixAI/ZarfixAICerdas1.0", device_map="auto")
-x = tok("You are a helpful assistant.", return_tensors="pt").to(m.device)
-y = m.generate(**x, max_new_tokens=128)
-print(tok.decode(y[0], skip_special_tokens=True))

+# ZarfixAI Cerdas 1.0
+**Summary:**
+ZarfixAI Cerdas 1.0 is a 4B parameter language model built for fast, efficient, and intelligent text generation.
+Optimized for practical applications where cost, speed, and accuracy matter.
+> Based on `janhq/Jan-v1-4B`. Original work is licensed under Apache-2.0 (see `LICENSE` in this repo).
+---
+## 🚀 Features
+- **4B parameters** for a balance between performance and efficiency
+- Supports **instruction-following** and **general conversation**
+- Runs on consumer GPUs or cloud T4 instances for low-cost deployment
+- Apache-2.0 license — flexible for commercial and personal projects
+---
+## 🛠️ Quickstart
 ```python
 from transformers import AutoTokenizer, AutoModelForCausalLM
+model_id = "ZarfixAI/ZarfixAICerdas1.0"
+tokenizer = AutoTokenizer.from_pretrained(model_id)
+model = AutoModelForCausalLM.from_pretrained(model_id, device_map="auto")
+prompt = "Explain the importance of renewable energy in simple terms."
+inputs = tokenizer(prompt, return_tensors="pt").to(model.device)
+outputs = model.generate(**inputs, max_new_tokens=256)
+print(tokenizer.decode(outputs[0], skip_special_tokens=True))
+````
+---
+## 💡 Recommended Use Cases
+* Customer support bots
+* Knowledge assistants
+* Educational Q\&A
+* Creative writing prompts
+* Lightweight RAG (Retrieval-Augmented Generation) systems
+---
+## ⚠️ Limitations
+* The model may produce inaccurate or biased outputs — always verify important information.
+* Not fine-tuned for high-risk applications (medical, legal, financial advice).
+---
+## 📜 License
+* Original model: `janhq/Jan-v1-4B` under Apache-2.0 license.
+* ZarfixAI Cerdas 1.0: Derivative work under the same Apache-2.0 license.
+* You are free to use, modify, and deploy, but must keep attribution to the original authors.
