Mixtral-8x7b-Instruct works on an old GTX1080!

Today, on a whim, I decided to try running the Mixtral 8x7b-Instruct model (via Ollama) on my old Linux GPU tower. Specifically, I am using the 4-bit quantized model. To my surprise, it works!

As always, in LlamaBot, this is relatively easy. To start, on my GPU server, I ran:

ollama pull mixtral:8x7b-instruct-v0.1-q4_0

Then, within my Jupyter on my MacBook Air:

keywords_sysprompt = """"Generate keywords for the document provided to you.
Please return JSON of format:

    {'keywords': ['keyword', 'keyword', 'keyword',...]}.


Keywords should be one or two words, separated by a space.
Return only keywords, nothing else.
Do not add your own commentary.
"""

keyword_generator_ollama = SimpleBot(
    model_name="ollama/mixtral:8x7b-instruct-v0.1-q4_0",  # Specifying Ollama via the model_name argument is necessary!s
    system_prompt=keywords_sysprompt,
    stream_target="stdout",  # this is the default!
    api_base=f"http://{os.getenv('OLLAMA_SERVER')}:11434",
    # json_mode=True,
    # format="json",
)

response = keyword_generator_ollama(document)

In generating keywords for a paper on protein engineering and machine learning, I had the following:

{'keywords': ['machine learning', 'functional protein design', 'AI', 'protein sequence', 'structure data', 'core data modalities', 'enzymes', 'antibodies', 'vaccines', 'nanomachines', 'large-scale assays', 'robust benchmarks', 'multimodal foundation models', 'enhanced sampling strategies', 'laboratory automation', 'protein fitness landscape', 'rational design methods', 'directed evolution', 'combinatorial libraries', 'biophysics-based models', 'DNA sequencing', 'algorithmic advances', 'computing advances', 'machine learning-based design methods']}

This wasn't too bad at all; it feels similar to what GPT-4 would provide, which has been on par with what I've observed with Mixtral-8x7b's output quality. The thing is qualitatively much slower than running mistral-7b (I have not measured tokens per second yet), but it does work.

As I mentioned in my previous post, running LLMs on my old GPU tower helped me breathe some new usage life into it. Running Mixtral-8x7b was another hardware challenge that I was eager to see, and I'm glad to have more evidence that LLMs can run on older commodity hardware!
