Choosing the right LLM shouldn't feel like gambling. One of our devs spent 2+ weeks testing models manually — just to automate a simple internal JSON task. The problem? Benchmarks didn’t reflect his task. They were too generic, too academic, and not useful in practice. So we built MIOSN: A model selection tool that works the way real teams work. With MIOSN, you can: Define your actual task — using your own inputs & outputs Set what matters (accuracy, cost, speed, JSON validity...) Test multiple LLMs in parallel Score and compare results automatically It’s like headhunting — but for language models. Get a clear, structured report showing: Top-performing models for your use case Trade-offs between cost, speed, and quality Where each model struggles (before you deploy it) We've been using MIOSN internally, and it's already saved us hours of guesswork. Now we're opening it up to others facing the same challenge. https://miosn.com Would love feedback from anyone building with LLMs or tired of “just try GPT-4 and see.”

It becomes hideous when every task requires you to sample across a plethora of models.

What is the pricing as I am not seeing it on the site?

@thefullstack Hi, Im Mark.
You’re absolutely right — testing every model in the pool takes time, money, and, above all, patience.

As for pricing: we haven’t rolled out billing yet. We're focused on working closely with users to refine the experience together. That’s why we’re giving new users free credits to test things out.

If you ever need more credits, just reach out to us on discord— we’ll be more than happy to give out more credits!

@chohchmark Our org constantly requires to test through models for their coding capabilities. We have our own benchmarks and more or less rely on human to evaluate the outputs. If this can be automated in some ways, that would be very useful.

@thefullstack Coding capabilities is one of the most important practical benchmarks I agree. We already have implemented batch evaluations (we decided to call this batch: an interview) on auto, so how about we let you guys know when coding capabilities become one of our new evaluation criterion in the near future? We are on the way and hope to become one of your main supporters soon.

@charvibothra True! We couldn't agree with you more.
The fact that there are more than 300+ LLMs on a single unified endpoint like the "openrouter" to even start with... We had to make a solution, and are here to help those who face same challenges!
