+A language model distilled and finetuned from an adapted version of LLaMA2-7B following "Towards the Law of Capacity Gap in Distilling Language Models".
+
+Outperforming a wide range of 3B competitors in GPT4 evaluation and even competing with several 7B chat models.

+from conversation import get_default_conv_template

+# MiniChat

+# CPU.
+# model = AutoModelForCausalLM.from_pretrained("GeneZC/MiniChat-3B", use_cache=True, device_map="cpu", torch_dtype=torch.float16).eval()
+
+conv = get_default_conv_template("minichat")
+
+question = "Implement a program to find the common elements in two arrays without using any extra data structures."
+conv.append_message(conv.roles[0], question)
+conv.append_message(conv.roles[1], None)
+prompt = conv.get_prompt()
+input_ids = tokenizer([prompt]).input_ids
+output_ids = model.generate(
+    torch.as_tensor(input_ids).cuda(),
+    do_sample=True,
+    temperature=0.7,
+    max_new_tokens=1024,
+)
+output_ids = output_ids[0][len(input_ids[0]):]
+output = tokenizer.decode(output_ids, skip_special_tokens=True).strip()
+# output: "def common_elements(arr1, arr2):\n    if len(arr1) == 0:\n        return []\n    if len(arr2) == 0:\n        return arr1\n\n    common_elements = []\n    for element in arr1:\n        if element in arr2:\n            common_elements.append(element)\n\n    return common_elements"
