How to run StarCoderBase 1B SFT on a MacBook Pro with Apple Silicon

These are notes on how I managed to get StarCoderBase-1B-SFT model compiled into a quantized version such that it can run locally on my MBP M1 Pro and be queryable through an OpenAI API-compatible server. [StarCoderBase][1] is a model trained/tuned for programming tasks. The [1B parameters SFT model][2] I am using in this article is a version of the model that has had supervised fine tuning applied to it. I am just going to call this "StarCoder" in the rest of this article for the sake of simplicity. Number of parameters that a model has is going to impact resource usage, so a smaller version of the model makes it more

Setting session variables in an RSpec Rails request spec

You are writing a spec with type: :request, i.e. an integration spec instead of a controller spec. Integration specs are wrappers around Rails' ActionDispatch::IntegrationTest class. I usually write controller tests using this instead of type: :controller, mainly because it exercises more of the request and response handling stack. So instead of writing something like get :index to start the request, you would write get books_path or similar.

One of the issues with using type: :request is that you lose the ability to

Installing mysql2 gem

This is always an annoying process, especially when you are setting up a new computer. I assume you are using macOS + homebrew. I also assume that you want to run an older version of MySQL (although the instructions should be adaptable).

Installing MySQL

$ brew install mysql@5.7 # change the version if needed

Genshin Impact: Albedo vs Mona crafting talent, who is better?

In Genshin Impact, you can craft materials of a given rank from three materials of the rank just below, eg. you can craft one gold book from three blue books.

Albedo has a talent where crafting a weapon ascension material has a 10% chance of giving double the output. Mona has a talent where crafting a weapon ascension material has a 25% chance of refunding a portion of the input materials.

In Rails 5, the preferred base class for testing controllers is ActionDispatch::IntegrationTest.

If you have an API that receives parameters as JSON request bodies, here are some helper methods to facilitate testing:

class ActionDispatch::IntegrationTest
  def put_json(path, obj)
    put path, params: obj.to_json, headers: { 'CONTENT_TYPE' => 'application/json' }
  end
