## News 🔥🔥🔥 [2024/04/15]
|
114 |
|
115 |
-
We introduce and opensource WizardLM-2, our next generation state-of-the-art large language models,
|
116 |
-
which have improved performance on complex chat, multilingual, reasoning and agent.
|
117 |
-
New family includes three cutting-edge models: WizardLM-2 8x22B, WizardLM-2 70B, and WizardLM-2 7B.
|
118 |
|
119 |
-
|
120 |
-
and consistently outperforms all the existing state-of-the-art opensource models.
|
121 |
-
- WizardLM-2 70B reaches top-tier reasoning capabilities and is the first choice in the same size.
|
122 |
-
- WizardLM-2 7B is the fastest and achieves comparable performance with existing 10x larger opensource leading models.
|
123 |
-
|
124 |
-
For more details of WizardLM-2 please read our [release blog post](https://web.archive.org/web/20240415221214/https://wizardlm.github.io/WizardLM2/) and upcoming paper.

## Model Capacities

-
|
143 |
-
|
144 |
-
**MT-Bench**
|
145 |
-
|
146 |
-
We also adopt the automatic MT-Bench evaluation framework based on GPT-4 proposed by lmsys to assess the performance of models.
|
147 |
-
The WizardLM-2 8x22B even demonstrates highly competitive performance compared to the most advanced proprietary models.
|
148 |
-
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**
|
156 |
-
|
157 |
-
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.
|
158 |
-
We report the win:loss rate without tie:
|
159 |
-
|
160 |
-
- WizardLM-2 8x22B is just slightly falling behind GPT-4-1106-preview, and significantly stronger than Command R Plus and GPT4-0314.
|
161 |
-
- WizardLM-2 70B is better than GPT4-0613, Mistral-Large, and Qwen1.5-72B-Chat.
|
162 |
-
- WizardLM-2 7B is comparable with Qwen1.5-32B-Chat, and surpasses Qwen1.5-14B-Chat and Starling-LM-7B-beta.

-
❗<b>Note for model system prompts usage:</b>
|
186 |
-
|
187 |
-
|
188 |
-
<b>WizardLM-2</b> adopts the prompt format from <b>Vicuna</b> and supports **multi-turn** conversation. The prompt should be as following:
|
189 |
-
|
190 |
-
```
|
191 |
-
A chat between a curious user and an artificial intelligence assistant. The assistant gives helpful,
|
192 |
-
detailed, and polite answers to the user's questions. USER: Hi ASSISTANT: Hello.</s>
|
193 |
-
USER: Who are you? ASSISTANT: I am WizardLM.</s>......

Quantized model => https://huggingface.co/alpindale/WizardLM-2-8x22B
|
101 |
|
102 |
+
**Quantization Details:**
|
103 |
+
Quantization is done using turboderp's ExLlamaV2 v0.2.2.
|
104 |
|
105 |
+
I use the default calibration datasets and arguments. The repo also includes a "measurement.json" file, which was used during the quantization process.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
106 |
|
107 |
+
For models with bits per weight (BPW) over 6.0, I default to quantizing the `lm_head` layer at 8 bits instead of the standard 6 bits.

**Who are you? What's with these weird BPWs on [insert model here]?**
|
114 |
+
I specialize in optimized EXL2 quantization for models in the 70B to 100B+ range, specifically tailored for 48GB VRAM setups. My rig is built using 2 x 3090s with a Ryzen APU (APU used solely for desktop output—no VRAM wasted on the 3090s). I use TabbyAPI for inference, targeting context sizes between 32K and 64K.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
115 |
|
116 |
+
Every model I upload includes a `config.yml` file with my ideal TabbyAPI settings. If you're using my config, don’t forget to set `PYTORCH_CUDA_ALLOC_CONF=backend:cudaMallocAsync` to save some VRAM.
