+## Training Details
+
+### Training Method
+
+We used LoRA to speed up the training process, targeting the q_proj, k_proj, v_proj, and o_proj modules.
+
+## Uses
+
+To accelerate the inference, we strongly recommend running Jellyfish using [vLLM](https://github.com/vllm-project/vllm).
+<!-- Address questions around how the model is intended to be used, including the foreseeable users of the model and those affected by the model. -->
+
+### Python Script
+We provide two simple Python code examples for inference using the Jellyfish model.  
+
+#### Using Transformers and Torch Modules
+<div style="height: auto; max-height: 400px; overflow-y: scroll;">
+  
+```python
+from transformers import AutoModelForCausalLM, AutoTokenizer, GenerationConfig
+import torch
+
+if torch.cuda.is_available():
+    device = "cuda"
+else:
+    device = "cpu"
+
+# Model will be automatically downloaded from HuggingFace model hub if not cached.
+# Model files will be cached in "~/.cache/huggingface/hub/models--NECOUDBFM--Jellyfish/" by default.
+# You can also download the model manually and replace the model name with the path to the model files.
+model = AutoModelForCausalLM.from_pretrained(
+    "NECOUDBFM/Jellyfish",
+    torch_dtype=torch.float16,
+    device_map="auto",
+)
+tokenizer = AutoTokenizer.from_pretrained("NECOUDBFM/Jellyfish")
+
+system_message = "You are an AI assistant that follows instruction extremely well. Help as much as you can."
+
+# You need to define the user_message variable based on the task and the data you want to test on.
+user_message = "Hello, world."
+
+prompt = f"<|start_header_id|>system<|end_header_id|>{system message}<|eot_id|>\n<|start_header_id|>user<|end_header_id|>{user_message}<|eot_id|>\n<|start_header_id|>assistant<|end_header_id|>"
+inputs = tokenizer(prompt, return_tensors="pt")
+input_ids = inputs["input_ids"].to(device)
+
+# You can modify the sampling parameters according to your needs.
+generation_config = GenerationConfig(
+    do_samples=True,
+    temperature=0.35,
+    top_p=0.9,
+)
+
+with torch.no_grad():
+    generation_output = model.generate(
+        input_ids=input_ids,
+        generation_config=generation_config,
+        return_dict_in_generate=True,
+        output_scores=True,

+        pad_token_id=tokenizer.eos_token_id,
+        repetition_penalty=1.15,
+    )
+
+output = generation_output[0]
+response = tokenizer.decode(
+    output[:, input_ids.shape[-1] :][0], skip_special_tokens=True
+).strip()
+
+print(response)
+
+```

+
+#### Using vLLM
+<div style="height: auto; max-height: 400px; overflow-y: scroll;">
+  
+```python
+from vllm import LLM, SamplingParams
+
+# To use vllm for inference, you need to download the model files either using HuggingFace model hub or manually.
+# You should modify the path to the model according to your local environment.
+path_to_model = (
+    "/workspace/models/Jellyfish"
+)
+
+model = LLM(model=path_to_model)
+
+# You can modify the sampling parameters according to your needs.
+# Caution: The stop parameter should not be changed.
+sampling_params = SamplingParams(
+    temperature=0.35,
+    top_p=0.9,
+    max_tokens=1024,
+    stop=["<|eot_id|>"],
+)
+
+system_message = "You are an AI assistant that follows instruction extremely well. Help as much as you can."
+
+# You need to define the user_message variable based on the task and the data you want to test on.
+user_message = "Hello, world."
+
+prompt = ff"<|start_header_id|>system<|end_header_id|>{system message}<|eot_id|>\n<|start_header_id|>user<|end_header_id|>{user_message}<|eot_id|>\n<|start_header_id|>assistant<|end_header_id|>"
+outputs = model.generate(prompt, sampling_params)
+response = outputs[0].outputs[0].text.strip()
+print(response)
+
+```
+</div>

 ## Prompts
 
 We provide the prompts used for both fine-tuning and inference.
