Currently Deepseek has updated FIM Completion feature, I hope openrouter can update this feature, so that it can be used for code assistants like copilot plugin.
The specific FIM Completion (Beta) update address: https://platform.deepseek.com/api-docs/api/create-completion/
Looking forward to openrouter's update!
