| ## News 🔥🔥🔥 [2024/04/15] |
|
|
| We introduce and opensource WizardLM-2, our next generation state-of-the-art large language models, |
| which have improved performance on complex chat, multilingual, reasoning and agent. |
| New family includes three cutting-edge models: WizardLM-2 8x22B, WizardLM-2 70B, and WizardLM-2 7B. |
|
|
| - WizardLM-2 8x22B is our most advanced model, demonstrates highly competitive performance compared to those leading proprietary works |
| and consistently outperforms all the existing state-of-the-art opensource models. |
| - WizardLM-2 70B reaches top-tier reasoning capabilities and is the first choice in the same size. |
| - WizardLM-2 7B is the fastest and achieves comparable performance with existing 10x larger opensource leading models. |
|
|
| For more details of WizardLM-2 please read our [release blog post](https://wizardlm.github.io/WizardLM2) and upcoming paper. |

| ## Model Capacities |
|
|
|
|
| **MT-Bench** |
|
|
| We also adopt the automatic MT-Bench evaluation framework based on GPT-4 proposed by lmsys to assess the performance of models. |
| The WizardLM-2 8x22B even demonstrates highly competitive performance compared to the most advanced proprietary models. |
| Meanwhile, WizardLM-2 7B and WizardLM-2 70B are all the top-performing models among the other leading baselines at 7B to 70B model scales. |

| </p> |
|
|
|
|
| **Human Preferences Evaluation** |
|
|
| We carefully collected a complex and challenging set consisting of real-world instructions, which includes main requirements of humanity, such as writing, coding, math, reasoning, agent, and multilingual. |
| We report the win:loss rate without tie: |
|
|
| - WizardLM-2 8x22B is just slightly falling behind GPT-4-1106-preview, and significantly stronger than Command R Plus and GPT4-0314. |
| - WizardLM-2 70B is better than GPT4-0613, Mistral-Large, and Qwen1.5-72B-Chat. |
| - WizardLM-2 7B is comparable with Qwen1.5-32B-Chat, and surpasses Qwen1.5-14B-Chat and Starling-LM-7B-beta. |

| ## Usage |
|
|
| ❗<b>Note for model system prompts usage:</b> |
|
|
|
|
| <b>WizardLM-2</b> adopts the prompt format from <b>Vicuna</b> and supports **multi-turn** conversation. The prompt should be as following: |
|
|
| ``` |
| A chat between a curious user and an artificial intelligence assistant. The assistant gives helpful, |
| detailed, and polite answers to the user's questions. USER: Hi ASSISTANT: Hello.</s> |
| USER: Who are you? ASSISTANT: I am WizardLM.</s>...... |
| ``` |
|
|
| <b> Inference WizardLM-2 Demo Script</b> |
|
|
| We provide a WizardLM-2 inference demo [code](https://github.com/nlpxucan/WizardLM/tree/main/demo) on our github. |
