- This repo contains weights that are compatible with [vLLM](https://github.com/vllm-project/vllm) serving of the model as well as Hugging Face [transformers](https://github.com/huggingface/transformers) library. It is based on the original Mixtral [torrent release](magnet:?xt=urn:btih:5546272da9065eddeb6fcd7ffddeef5b75be79a7&dn=mixtral-8x7b-32kseqlen&tr=udp%3A%2F%http://2Fopentracker.i2p.rocks%3A6969%2Fannounce&tr=http%3A%2F%http://2Ftracker.openbittorrent.com%3A80%2Fannounce), but the file format and parameter names are different. Please note that model cannot (yet) be instantiated with HF.

21
- ```python
22
- from transformers import AutoModelForCausalLM, AutoTokenizer
23
-
24
- model_id = "mistralai/Mixtral-8x7B-v0.1"
25
- tokenizer = AutoTokenizer.from_pretrained(model_id)
26
-
27
- model = AutoModelForCausalLM.from_pretrained(model_id)
28
-
29
- text = "Hello my name is"
30
- inputs = tokenizer(text, return_tensors="pt")
31
-
32
- outputs = model.generate(**inputs, max_new_tokens=20)
33
- print(tokenizer.decode(outputs[0], skip_special_tokens=True))
34
- ```

- By default, transformers will load the model in full precision. Therefore you might be interested to further reduce down the memory requirements to run the model through the optimizations we offer in HF ecosystem:

- ### In half-precision
