Inference

Via transfomers

!pip install -qU transformers bitsandbytes accelerate

from transformers import AutoTokenizer
import transformers
import torch

model = "saucam/Hikari-4x7B"

tokenizer = AutoTokenizer.from_pretrained(model)
pipeline = transformers.pipeline(
    "text-generation",
    model=model,
    model_kwargs={"torch_dtype": torch.float16, "load_in_4bit": False},
)

messages = [{"role": "user", "content": "Explain what a Mixture of Experts is in less than 100 words."}]
prompt = pipeline.tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
outputs = pipeline(prompt, max_new_tokens=256, do_sample=True, temperature=0.7, top_k=50, top_p=0.95)
print(outputs[0]["generated_text"])

Sample responses:

No chat template is defined for this tokenizer - using the default template for the LlamaTokenizerFast class. If the default is not a
ppropriate for your model, please set `tokenizer.chat_template` to an appropriate template. See https://huggingface.co/docs/transform
ers/main/chat_templating for more information.

Explain what a Mixture of Experts is in less than 100 words. [/INST] A Mixture of Experts (MoE) is a neural network architecture that
 was introduced in the 1990s. It is based on the idea of having a set of expert networks, each specialized in a particular part of th
e input space, and then combining their outputs to produce a final prediction.

The Mixture of Experts architecture is well-suited for tasks such as speech recognition and natural language processing, where the in
put data can be divided into distinct categories or classes, and each expert network can be trained to specialize in one of these cat
egories.

The combining mechanism in a MoE network can be a simple weighted average or a more complex function, such as a Bayesian mixture mode
l. The weights assigned to each expert network are learned during training, based on the accuracy of their predictions.

In summary, a Mixture of Experts is a neural network architecture that combines the strengths of multiple specialized networks to pro
duce a more accurate prediction than any individual network alone.

I hope this helps! Let me know if you have any other questions. 😊

Interestingly we see a few sentences in Japanese when asked!

Explain what a Mixture of Experts is in less than 100 words. Answer in japanese [/INST] 「Mixture of Experts」とは、機械学習アルGorithmの一種である「Experts」に複数の専門知識を持つモデルをを組み合わせる学習方法である。

この手法は especially useful in situations where、各分野 has a high degree of specialization and the data set is large、 and it can be used to improve the performance of the model by combining the knowledge of various experts.

The「Mixture of Experts」alGorithm works by dividing the input space into multiple partitions and assigning an "expert" to each partition. The "experts" are then trained on their respective partitions of the data, and at prediction time, the input is passed to all the "experts," and their predictions are combined to produce the final output.

The「Mixture of Experts」alGorithm is used in various applications, such as speech recognition、object recognition、 and natural language processing.
