       Show HN: Create your own finetuned AI model using Google Sheets
        
       Hello HN,  We built Promptrepo to make finetuning accessible to
       product teams -- not just ML engineers. Last week, OpenAI's CPO
       shared how they use fine-tuning for everything from customer
       support to deep research, and called it the future for serious AI
       teams. Yet most teams I know still rely on prompting, because fine-
       tuning is too technical, while the people who have the training
       data (product managers and domain experts) are often non-technical.
       With Promptrepo, they can now:  - Add training examples in Google
       Sheets  - Click a button to train  - Deploy and test instantly  -
       Use OpenAI, Claude, Gemini or Llama models  We've used this
       internally for years to power AI workflows in our products
       (Formfacade, Formesign, Neartail), and we're now opening it up to
       others. Would love your feedback and happy to answer any questions!

       | Incredibly crowded space, but this is a great insight and UI...
       | engineers probably have to integrate the model but we should
       | empower non-technical customer-facing people to give feedback to
       | the model in a way that improves it.
       | 
       | The blocker for me (and likely other cost-conscious early stage
       | groups)? I have free credit and existing integrations with more
       | mainstream platforms (OpenAI, anthropic, together). Trying this
       | out will cost both eng time and money, so I won't be an early
       | adopter. I wonder if there's a way to pass the cost through / use
       | my API keys with credits. Maybe it's more for enterprise teams or
       | cases where you're already confident about the fine-tuning
       | approach.
       | 
       | Anyway, congrats on the launch!

       | Your biggest obstacle is proving fine-tuning is more effective
       | than prompting, workflow design, RAG, etc during the initial
       | pass. Most of my customers are still getting big improvements by
       | picking the low-hanging fruit with those approaches. A much
       | smaller fraction is at a place where they're ready to start fine-
       | tuning. Obviously, this will change as AI programs mature.
        
         | manidoraisamy wrote:
         | Exactly! Finetuning needs at least 10 examples to even work.
         | That's why Promptrepo begins with prompting and schema-based
         | generation when teams have little or no data. As they gather
         | more examples, it gradually shifts to fine-tuning. It's the
         | classic cold start problem and we've simplified it for product
         | teams who want to launch quickly but improve accuracy over
         | time.

         | We don't have automated evals, latency, or cost comparisons

         | these comparisons is definitely on our roadmap.

         | Agree, not super familiar with this space but that you are

           | the projects are isolated. They'll use memory configurable in
           | settings but they don't use chat history outside the project.
           | This can give ChatGPT chats in projects a different tone.
           | 
           | My question is this: Is this fine tuning with those project
           | documents or RAG and what's the difference?

             | Promptrepo is for developers and product teams to build new
             | AI-powered features in their product. It's about creating
             | custom models that run behind the scenes in apps, not just
             | improving a personal chat experience.
             | 
             | So while OpenAI projects use RAG for better chats,
             | Promptrepo helps teams build and deploy fine-tuned APIs
             | that serve structured outputs like JSON, labels, or
             | extracted fields to build your own AI powered product.

       | 
       | But I do see the value! Think sales or marketing folks looking to
       | get a bit more hands on. These will likely be your first visitor
       | and be okay with your 50 dollar price. Then, their IT department
       | will say "we want to hook up our own API key for that," to which
       | you can confidently say "sure, we can do that too."
       | 
       | N=1, just my two cents. Good luck!
