Deepseek API Support Triage

Thank you for suggesting Deepseek API support! This feature aligns well with MyCoder's goal of providing flexible AI provider options.

Implementation Approach

Based on the existing provider implementation pattern in MyCoder, adding Deepseek support would involve:

1. Adding Deepseek to the provider registry in provider.ts
2. Creating a new deepseek.ts provider implementation file
3. Implementing the LLMProvider interface for Deepseek

Additional Information Needed

To proceed with implementation, it would be helpful to have more details about:

• Deepseek API documentation link
• Authentication method (API key structure)
• Base URL for API endpoints
• Available models and their context window sizes
• Whether the API is OpenAI-compatible (which seems likely based on research)

Next Steps

I've added the enhancement label to this issue. Once we have more details about the API, we can move forward with implementation.

The lower API cost you mentioned is definitely a compelling reason to add support for this provider. If you have any specific cost comparisons or other benefits to highlight, please share them.

@drpetersonfernandes The DeepSeek documentation says this:

"The DeepSeek API uses an API format compatible with OpenAI. By modifying the configuration, you can use the OpenAI SDK or softwares compatible with the OpenAI API to access the DeepSeek API."

The current implementation of the OpenaI provider in mycoder supports overriding the baseUrl, which means you can point it at DeepSeek's API:

https://docs.mycoder.ai/docs/providers/openai#using-openai-compatible-providers

Just set in mycoder.config.js:

{
   ...
   provider: 'openai',
   model: 'deepseek-chat'
   baseUrl: "https://api.deepseek.com",
  ....,
}

And set OPENAI_API_KEY to be your deep seek key.

Basically I think it would work now without any modifications.
