## News π₯π₯π₯ [2024/04/15]
|
32 |
+
|
33 |
+
We introduce and opensource WizardLM-2, our next generation state-of-the-art large language models,
|
34 |
+
which have improved performance on complex chat, multilingual, reasoning and agent.
|
35 |
+
New family includes three cutting-edge models: WizardLM-2 8x22B, WizardLM-2 70B, and WizardLM-2 7B.
|
36 |
+
|
37 |
+
- WizardLM-2 8x22B is our most advanced model, demonstrates highly competitive performance compared to those leading proprietary works
|
38 |
+
and consistently outperforms all the existing state-of-the-art opensource models.
|
39 |
+
- WizardLM-2 70B reaches top-tier reasoning capabilities and is the first choice in the same size.
|
40 |
+
- WizardLM-2 7B is the fastest and achieves comparable performance with existing 10x larger opensource leading models.
|
41 |
+
|
42 |
+
For more details of WizardLM-2 please read our [release blog post](https://wizardlm.github.io/WizardLM2) and upcoming paper.

## Model Capacities

+
|
61 |
+
|
62 |
+
**MT-Bench**
|
63 |
+
|
64 |
+
We also adopt the automatic MT-Bench evaluation framework based on GPT-4 proposed by lmsys to assess the performance of models.
|
65 |
+
The WizardLM-2 8x22B even demonstrates highly competitive performance compared to the most advanced proprietary models.
|
66 |
+
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.

**Human Preferences Evaluation**
|
74 |
+
|
75 |
+
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.
|
76 |
+
We report the win:loss rate without tie:
|
77 |
+
|
78 |
+
- WizardLM-2 8x22B is just slightly falling behind GPT-4-1106-preview, and significantly stronger than Command R Plus and GPT4-0314.
|
79 |
+
- WizardLM-2 70B is better than GPT4-0613, Mistral-Large, and Qwen1.5-72B-Chat.
|
80 |
+
- WizardLM-2 7B is comparable with Qwen1.5-32B-Chat, and surpasses Qwen1.5-14B-Chat and Starling-LM-7B-beta.
