• Use Java-naming conventions for attributes in the request/response models instead of the snake-case conventions. ( possibly with Jackson-mapper's @JsonProperty)
• Fix deprecated HTTP client code
• Setup logging
• Use lombok
• Update request body creation with Java objects
• Async APIs for images
• Add custom headers to requests
• Add additional params for ask APIs such as:
  • options: additional model parameters for the Modelfile such as temperature - Supported params.
  • 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)

Contributions are most welcome! Whether it's reporting a bug, proposing an enhancement, or helping with code - any sort of contribution is much appreciated.

The nomenclature and the icon have been adopted from the incredible Ollama project.
