Simple model to make addition and answer is send to supabase

This model runs on CPU hardware.


What do and how work this model

What do this model

This model name 1_Test do not use ML algorithm, it’s a test for know how to use replicate and cog. This model use supabase librairy made by community for insert output of the model.

User put a and b integer and sum of a+b. This model while give a answer if user make good or wrong calcul and seed this to supabase.

How this model work

Before start, we need to have Cog and Docker. For learn Cog, click her for Github Doc. But for start, use brew for install Cog :

brew install cog

After for this model, i use only 3 files :

All the code is in this repo Github.

Or, let check all code her :

Let’s check my other model !
