    Timely. I have been battling getting function calling to wotk right. Sadly, many of the examples out there don't work with different models, they seem to all assume OpenAI. I look forward to giving your approach a try!

  • @ElvinHoney707

    You are correct! Function calling is actually made possible simply by the reasoning capacity, such that it is, of the model. There is nothing more than that. It is a convenient abstraction for service interactions. Instead of function calling we could just call it "if you think you need it you may ask for the following ...". BTW, this type of process reasoning is also used for agentic interactions when deciding workflows.

    Would you mind answering a question? With you use this do we essentially pass in the instructions each time we prompt? For example if i tried to do this manually, i would just repeat my instructions each time (which also include the formatting) along with the new question? I wasnt sure what system prompt vs user prompt means, do they both end up in the same place anyway

    I love your videos, man. This is one big thing I’ve picked up along my journey:
    Always start from specific information or ideas, and go towards generalities (not the other way around).
    In a classroom setting, where people prepare their wallets and minds for a learning event, maybe starting with generalities is better. But in real life, there are so many distractions. Distractions lead to confusion. Confusion leads to annoyance and madness.
    Moderate specificity requires the least amount of a consumer’s time and attention to get started. Maximizes potential engagement. Minimizes annoyance or friction.
    Am always telling support or client-facing folks this exact same thing when they ask wide open questions, and then complain that devs are frustrated or taking a long time to respond. Or maybe the dev team is falling behind on a new feature (of course they will when always having to context switch due to wide open query or too many unresolved details).
    Goes back to starting from specific details, so the consumer remains locked into their original intent and context, as much as possible. Not everyone who clicks here and watches these videos is watching with pen and paper in hand taking notes for a college exam. In order to potentiate their involvement, specific repeatable easy details are key.

    When it comes to function calling with lots of highly specific parameters I find that the models that I can run in ollama are simply uncapable of following the schema i provide. Whereas openai and claude do an excellent job following a large json schema. So when it comes to a mod being "trained for function calling" I think they mean trained to follow large and strict schemas well as thats really the main difference.
    You will see a difference if your function call (basically json output) needs to follow a large and strict schema. Everyones examples are too small to notice the change.

    • @technovangelist
      @technovangelist  5 місяців тому +1

      Have you tried. I just tweaked my code to use 10 parameters per function. And gave a more complicated prompt. Worked just fine. But if you are doing that you probably have bigger issues outside of the model.

    And to your 2nd point. You 100% correct theirs no reason for a model to be finetuned for function calling, i discovered function calling with gpt3.5 about 3 months after chatgpts launch.

    The libraries are creating abstractions over a document and we can forget where the abstraction layer ends and where the substrate begins.
    I'm going to try out this pattern. Lots of libraries make it easy to swap out models expecting completions vs conversations... fewer libraries have a nice clean way to swap out models that handle function calling differently.

    that's amazingly simple, nice. I'm guessing one scenario where someone would still want an agent-framework is if the framework was a low/no-code workflow.
    I'd love to see a video on whether running models with GPTQ quantization is worthwhile. Most explanations I've seen amount to "GPTQ is for GPUs, GGML is for cpus" without saying why GPTQ is completely neglected in projects like ollama, or if there is even a meaningful advantage to either at this point.

      I think a lot of folks don’t realize that function calling is possible in ollama. There are folks who seem intent on spreading the notion that function calling is more than it is. And so they kind of brute force their way through rather than taking the simpler approach. But that’s just a guess. Can you point me to some of the issues you have seen?

    Hi Matt,
    I watched again this video with pleasure, and it got me thinking again :-). First of all, please avoid the trap of dividing your followers into lovers and haters. You produce top-notch content, and there's no need to apologize or dramatize (appreciating you irony).
    Let me delve into a point that emerged in your demo/experiment, which is, in my opinion, more significant than the function calling "issue". You verified that the majority of open-source models available on Ollama are able to produce the expected JSON. That's somewhat surprising to me. This demonstrates, as you suggested, that the OpenAI function-calling fine-tuned models are just marketing, but wait. I remember that the old GPT-3.5 OpenAI "instruct" models like "text-davinci-003" were able to produce JSON (so function calling-JSON if you will), but subsequent chat COMPLETION models (fine-tuned for lists of system/assistant/user messages) weren't! So, my guess is that OpenAI released the function-calling fine-tuned models later to correct the chat-completion fine-tuning?! Ironic again.
    But, back to the Ollama models-I'm still perplexed. Are these optimized for both (at the same run-time) CHAT completion and "function calling" (aka JSON outputs)? This could maybe be a topic for another video...?
    By the way, it would be kind of you to share the code on your GitHub repo as usual, but anyway the video is absolutely explanatory.
    I'll take a look at the "Tools" #5284 Ollama PR. In my opinion, standardization could help the community around Ollama, even if you demonstrated that any user-made schema does the job.
    Thanks always for sharing great content. I appreciate your effort.

As long as I make my own scripts that talks directly to the ollama API, why would I not be able to "ask it to return json" and simply run functions in my script based on the response?
