Deepseek API support needed

[wangxianyu7]

Dear Developer,

The recently popular LLM, DeepSeek (https://www.deepseek.com/), is priced lower than most other LLMs. Would you consider adding support for it in your plugin? This would be a great help to users and save them a significant amount of money.

Thank you so much!

Yes, I will definitely add it. I've been pretty busy with some other things recently so I haven't been very active, but I plan to resolve a bunch of overdue issues (including this one) in the coming weeks.

If you want to use DeepSeek immediately (before I add support for it), I believe you can make it work by doing the following:

1. Choose OpenAI as your Provider in the settings.
2. Enter your DeepSeek API key in the OpenAI API key setting.
3. Enter https://api.deepseek.com/v1 in the OpenAI API base url setting.
4. Open the data.json file for this plugin and change the value of openAITextGenModel to either deepseek-chat (to use DeepSeek-V3) or deepseek-reasoner (to use DeepSeek-R1). If you go back to Obsidian, the dropdown toggle for the Generation model setting should now be blank.

Yes this is a way of generating quiz with deepseek's api key, but when evaluating answers using embedding models it raises two issues:

1. CORS issue (I think this resembles Add custom model and enable CORS support #36)
2. deepseek does not provide any embedding model, so we might have to select a text embedding model from another provider.

Thank you for your effort on this plugin:)
