### Areas of improvement

- [x] Use Java-naming conventions for attributes in the request/response models instead of the
  snake-case conventions. (
  possibly with Jackson-mapper's `@JsonProperty`)
- [x] Fix deprecated HTTP client code
- [x] Setup logging
- [x] Use lombok
- [x] Update request body creation with Java objects
- [ ] Async APIs for images
- [ ] Add additional params for `ask` APIs such as:
    - `options`: additional model parameters for the Modelfile such as `temperature`
    - `system`: system prompt to (overrides what is defined in the Modelfile)
    - `template`: the full prompt or prompt template (overrides what is defined in the Modelfile)
    - `context`: the context parameter returned from a previous request, which can be used to keep a
      short
      conversational memory
    - `stream`: Add support for streaming responses from the model
- [ ] Add test cases
- [ ] Handle exceptions better (maybe throw more appropriate exceptions)
