aya-34-8B - llamafile

This repository contains executable weights (which we call llamafiles) that run on Linux, MacOS, Windows, FreeBSD, OpenBSD, and NetBSD for AMD64 and ARM64.

Model creator: CohereForAI
Original model: CohereForAI/aya-23-8B

This is multilingual model, with a focus on Arabic.

Quickstart

You can run the following commands which download, concatenate, and execute the model.

wget https://huggingface.co/jartine/aya-23-8B-llamafile/resolve/main/aya-23-8B.Q6_K.llamafile
chmod +x aya-23-8B.Q6_K.llamafile
./aya-23-8B.Q6_K.llamafile --help   # view manual
./aya-23-8B.Q6_K.llamafile          # launch web gui + oai api
./aya-23-8B.Q6_K.llamafile -p ...   # cli interface (scriptable)

Alternatively, you may download an official llamafile executable from Mozilla Ocho on GitHub, in which case you can use the Mixtral llamafiles as a simple weights data file.

llamafile -m ./aya-23-8B.Q6_K.llamafile ...

For further information, please see the llamafile README.

Prompting

Command-line instruction example:

./aya-23-8B.Q6_K.llamafile --log-disable --silent-prompt -p '<BOS_TOKEN>
<|START_OF_TURN_TOKEN|>
<|USER_TOKEN|>Who is the president?<|END_OF_TURN_TOKEN|>
<|START_OF_TURN_TOKEN|>
<|CHATBOT_TOKEN|>'

"Prompt Template" (copy and paste this into the web GUI):

<BOS_TOKEN>
<|SYSTEM_TOKEN|>{{prompt}}<|END_OF_TURN_TOKEN|>
{{history}}
<|START_OF_TURN_TOKEN|>
<|CHATBOT_TOKEN|>

"Chat history template" (copy and paste this into the web GUI):

<|START_OF_TURN_TOKEN|>
<|USER_TOKEN|>{{message}}<|END_OF_TURN_TOKEN|>

The maximum context size of this model is 8192 tokens. These llamafiles use a default context size of 512 tokens. Whenever you need the maximum context size to be available with llamafile for any given model, you can pass the -c 0 flag. The temperature on these llamafiles is set to zero by default, because it helps. This can be changed, e.g. --temp 0.8.

License

The aya-34-8B license requires:

You can't use these weights for commercial purposes
You have to give Cohere credit if you share or fine tune it
You can't use it for purposes they consider unacceptable, such as spam, misinformation, etc. The license says they can change the definition of acceptable use at will.
The CC-BY-NC 4.0 stipulates no downstream restrictions, so you can't tack on your own list of unacceptable uses too if you create and distribute a fine-tuned version.

This special license only applies to the LLM weights (i.e. the .gguf file inside .llamafile). The llamafile software itself is permissively licensed, having only components licensed under terms like Apache 2.0, MIT, BSD, ISC, zlib, etc.

About llamafile

llamafile is a new format introduced by Mozilla Ocho on Nov 20th 2023. It uses Cosmopolitan Libc to turn LLM weights into runnable llama.cpp binaries that run on the stock installs of six OSes for both ARM64 and AMD64.

In addition to being executables, llamafiles are also zip archives. Each llamafile contains a GGUF file, which you can extract using the unzip command. If you want to change or add files to your llamafiles, then the zipalign command (distributed on the llamafile github) should be used instead of the traditional zip command.

Model Summary

Aya 23 is an open weights research release of an instruction fine-tuned model with highly advanced multilingual capabilities. Aya 23 focuses on pairing a highly performant pre-trained Command family of models with the recently released Aya Collection. The result is a powerful multilingual large language model serving 23 languages.

This model card corresponds to the 8-billion version of the Aya 23 model. We also released a 35-billion version which you can find here.

We cover 23 languages: Arabic, Chinese (simplified & traditional), Czech, Dutch, English, French, German, Greek, Hebrew, Hindi, Indonesian, Italian, Japanese, Korean, Persian, Polish, Portuguese, Romanian, Russian, Spanish, Turkish, Ukrainian, and Vietnamese

Usage

Please install transformers from the source repository that includes the necessary changes for this model

# pip install transformers==4.41.1
from transformers import AutoTokenizer, AutoModelForCausalLM

model_id = "CohereForAI/aya-23-8B"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(model_id)

# Format message with the command-r-plus chat template
messages = [{"role": "user", "content": "Anneme onu ne kadar sevdiğimi anlatan bir mektup yaz"}]
input_ids = tokenizer.apply_chat_template(messages, tokenize=True, add_generation_prompt=True, return_tensors="pt")
## <BOS_TOKEN><|START_OF_TURN_TOKEN|><|USER_TOKEN|>Anneme onu ne kadar sevdiğimi anlatan bir mektup yaz<|END_OF_TURN_TOKEN|><|START_OF_TURN_TOKEN|><|CHATBOT_TOKEN|>

gen_tokens = model.generate(
    input_ids, 
    max_new_tokens=100, 
    do_sample=True, 
    temperature=0.3,
    )

gen_text = tokenizer.decode(gen_tokens[0])
print(gen_text)
