What is the difference between optimization software APIs based on performance and speed?
The difference between a C++ and Python API can be massive, but it also depends on the quality of the Python implementation.
A key factor to consider when setting expectations, is the way the API is ...

Will there be Rust APIs for state-of-the-art solvers?
This is what @mattmilten mentioned in the Gurobi forum.
There is no official native Rust API for Gurobi, yet. There are tool
to generate C bindings for Rust that you may be able to use to call

Does the API affect the time Gurobi requires to find an optimum?
In addition to @Richard's answer:
The time for setting up the model, i.e. declaring variables and constraints, surely depends on the programming language you use. After the model is ready, solving ...

Does the API affect the time Gurobi requires to find an optimum?
Once it’s passed to the underlying C library, it does not matter which API it came from. However, there may be some overhead when you are retrieving the solution through the API (for the same reasons ...

Deploying OR Model as an API
I have made OR models accessible through APIs on Kubernetes before. It isn't too hard, no pickling involved. In general, the steps aren't unique for an OR model API, but there might be a few things to ...

What is the difference between optimization software APIs based on performance and speed?
Python is a "slow" programming language because it is interpreted (at least CPython is), so in OR-Tools, for example, that impacts the model building speed if the model is big enough or your logic ...

Deploying OR Model as an API
I think in your case you have to separate between the data and the model. The model itself is part of the service in some way. Either you hard code it into the service or you have some sort of ...

Deploying OR Model as an API
I am unsure what exactly you want to pickle. Is the user posting data to your endpoint (the flask service)? In that case you probably need to re-run the algorithm.
In machine learning the model is ...
