+# AstroLLaMA-2-7B-Chat_AIC
+AstroLLaMA-2-7B-Chat_AIC is a specialized chat model for astronomy, developed by fine-tuning the AstroLLaMA-2-7B-Base_AIC model. This model was originally developed by the AstroLLaMA team as part of the UniverseTBD initiative. It is designed for instruction-following and chat-based interactions in the astronomy domain.
+**Note**: This model is provided for completeness in the series of AstroLLaMA models. The core AstroLLaMA team has since moved on to develop more advanced models under AstroMLab. For the original UniverseTBD version, please visit [their repository](https://huggingface.co/universeTBD/astrollama-7b-chat-alpha).
 ## Model Details
+- **Base Architecture**: LLaMA-2-7b
+- **Base Model**: AstroLLaMA-2-7B-Base_AIC (trained on Abstract, Introduction, and Conclusion sections from arXiv's astro-ph category papers)
+- **Fine-tuning Method**: Supervised Fine-Tuning (SFT)
+- **SFT Dataset**:
+  - 10,356 astronomy-centered conversations generated from arXiv abstracts by GPT-4
+  - Full content of LIMA dataset
+  - 10,000 samples from Open Orca dataset
+  - 10,000 samples from UltraChat dataset
+- **Primary Use**: Instruction-following and chat-based interactions for astronomy-related queries
+- **Reference**: [Perkowski et al. 2024](https://arxiv.org/abs/2401.01916)
+## Using the model for chat
+```python
+from transformers import AutoModelForCausalLM, AutoTokenizer
+import torch
+# Load the model and tokenizer
+tokenizer = AutoTokenizer.from_pretrained("AstroMLab/astrollama-2-7b-chat_aic")
+model = AutoModelForCausalLM.from_pretrained("AstroMLab/astrollama-2-7b-chat_aic", device_map="auto")
+# Function to generate a response
+def generate_response(prompt, max_length=512):
+    inputs = tokenizer(prompt, return_tensors="pt", truncation=True, max_length=max_length)
+    inputs = inputs.to(model.device)
+    # Generate a response
+    with torch.no_grad():
+        outputs = model.generate(**inputs, max_length=max_length, num_return_sequences=1, do_sample=True)
+    # Decode and return the response
+    response = tokenizer.decode(outputs[0], skip_special_tokens=True)
+    return response
+# Example conversation
+user_input = "What are the main components of a galaxy?"
+prompt = f"Human: {user_input}\n\nAssistant:"
+response = generate_response(prompt)
+print(response)
+```
+## Model Limitations and Biases
+This model is specifically trained on astronomy literature and conversation data, and may not generalize well to other domains. Users should be aware of potential biases in the training data, which may reflect historical trends and biases in astronomical research publications and the datasets used for fine-tuning.
+Importantly, this model has been superseded by more advanced versions. For state-of-the-art performance, we recommend using the latest models from AstroMLab.
+## Ethical Considerations
+While this model is designed for scientific use, users should be mindful of potential misuse, such as generating misleading scientific content. Always verify model outputs against peer-reviewed sources for critical applications.
