Changelog v1.0.5.2-release+1.21.1

This minor update of AI player updates the mod to version 1.21.1 and also brings support for other custom API providers.

Custom OpenAI-Compatible Provider Support

This feature allows you to use alternative AI providers that are compatible with the OpenAI API standard, such as OpenRouter, TogetherAI, Perplexity, and others.

How to Use

1. Enable Custom Provider Mode

Set the system property(JVM argument) when launching the game:

-Daiplayer.llmMode=custom

2. Configure API Settings

1. Firstly, delete the existing settings.json5 in the config folder (save any api keys elsewhere for the meantime)
2. Open the in-game API Keys configuration screen (/configMan) and then click the API Keys button.
3. Set the following fields:
   • Custom API URL: The base URL of your provider (e.g., https://openrouter.ai/api/v1)
   • Custom API Key: Your API key for the provider
4. Hit save. In case you don't see the list of models immediately hit the "Refresh Models" button once or twice.
5. If you still don't see the list of models, close the config manager, type /configMan again and you should see the list of models available.
6. ollama is still required to be open in the background because of the embedding model being used, but I will separate this entirely in the next mini patch, by adding an embedding api endpoint from the providers, and also upgrading to the embedddinggemma model from nomic-embed-text

3. Select a Model

The system will automatically fetch available models from your provider's /models endpoint and display them in the model selection interface.

Supported Providers

Any provider that implements the OpenAI API standard should work. Some examples:

• OpenRouter: https://openrouter.ai/api/v1
• TogetherAI: https://api.together.xyz/v1
• Perplexity: https://api.perplexity.ai/
• Groq: https://api.groq.com/openai/v1
• Local LM Studio: http://localhost:1234/v1

API Compatibility

The custom provider implementation uses the following OpenAI API endpoints:

• GET /models - For fetching available models
• POST /chat/completions - For sending chat completion requests

Your provider must support these endpoints with the same request/response format as OpenAI's API.

Troubleshooting

• "Custom provider selected but no API URL configured": Make sure you've set the Custom API URL field
• "Custom API key not set in config!": Make sure you've set the Custom API Key field
• Empty model list: Check that your API key is valid and the URL is correct
• Connection errors: Verify that the provider URL is accessible and supports the OpenAI API format
