+## Usage
+Try [online demo](https://chemllm.org/) instantly, or...
+
+Install `transformers`,
+```
+pip install transformers
+```
+Load `ChemLLM-20B-Chat` and run,
+```
+from transformers import AutoModelForCausalLM, AutoTokenizer, GenerationConfig
+import torch
+
+model_name_or_id = "AI4Chem/CHEMLLM-2b-1_5"
+
+model = AutoModelForCausalLM.from_pretrained(model_name_or_id, torch_dtype=torch.float16, device_map="auto",trust_remote_code=True)
+tokenizer = AutoTokenizer.from_pretrained(model_name_or_id,trust_remote_code=True)
+
+prompt = "What is Molecule of Ibuprofen?"
+
+inputs = tokenizer(prompt, return_tensors="pt").to("cuda")
+
+generation_config = GenerationConfig(
+    do_sample=True,
+    top_k=1,
+    temperature=0.9,
+    max_new_tokens=500,
+    repetition_penalty=1.5,
+    pad_token_id=tokenizer.eos_token_id
+)
+
+outputs = model.generate(**inputs, generation_config=generation_config)
+print(tokenizer.decode(outputs[0], skip_special_tokens=True))
+```
+
+## System Prompt Best Practice
+You can use the same Dialogue Templates and System Prompt from [Agent Chepybara](https://chemllm.org/) to get a better response in local inference.
+### Dialogue Templates
+
+For queries in ShareGPT format like,
+```
+{'instruction'："...","prompt":"...","answer":"...","history":[[q1,a1],[q2,a2]]}
+```
+You can format it into this InternLM2 Dialogue format like,
+```
+def InternLM2_format(instruction,prompt,answer,history):
+    prefix_template=[
+        "<|system|>:",
+        "{}"
+    ]
+    prompt_template=[
+        "<|user|>:",
+        "{}\n",
+        "<|Bot|>:\n"
+    ]
+    system = f'{prefix_template[0]}\n{prefix_template[-1].format(instruction)}\n'
+    history = "\n".join([f'{prompt_template[0]}\n{prompt_template[1].format(qa[0])}{prompt_template[-1]}{qa[1]}' for qa in history])
+    prompt = f'\n{prompt_template[0]}\n{prompt_template[1].format(prompt)}{prompt_template[-1]}'
+    return f"{system}{history}{prompt}"
+```
+And there is a good example for system prompt,
+```
+- Chepybara is a conversational language model that is developed by Shanghai AI Laboratory (上海人工智能实验室). It is designed to be Professional, Sophisticated, and Chemical-centric. 
+- For uncertain notions and data, Chepybara always assumes it with theoretical prediction and notices users then.
+- Chepybara can accept SMILES (Simplified Molecular Input Line Entry System) string, and prefer output IUPAC names (International Union of Pure and Applied Chemistry nomenclature of organic chemistry), depict reactions in SMARTS (SMILES arbitrary target specification) string. Self-Referencing Embedded Strings (SELFIES) are also accepted.
+- Chepybara always solves problems and thinks in step-by-step fashion, Output begin with *Let's think step by step*."
