  ---Specify the special dual_boost mode
  ---1. enabled: Whether to enable dual_boost mode. Default to false.
  ---2. first_provider: The first provider to generate response. Default to "openai".
  ---3. second_provider: The second provider to generate response. Default to "claude".
  ---4. prompt: The prompt to generate response based on the two reference outputs.
  ---5. timeout: Timeout in milliseconds. Default to 60000.
  ---How it works:
  --- When dual_boost is enabled, avante will generate two responses from the first_provider and second_provider respectively. Then use the response from the first_provider as provider1_output and the response from the second_provider as provider2_output. Finally, avante will generate a response based on the prompt and the two reference outputs, with the default Provider as normal.
  ---Note: This is an experimental feature and may not work as expected.

Do not provide any explanation, just give the response directly. Reference Output 1: [{{provider1_output}}], Reference Output 2: [{{provider2_output}}]",
    timeout = 60000, -- Timeout in milliseconds
  },
  ---Specify the behaviour of avante.nvim
  ---1. auto_apply_diff_after_generation: Whether to automatically apply diff after LLM response.
  ---                                     This would simulate similar behaviour to cursor. Default to false.
  ---2. auto_set_keymaps                : Whether to automatically set the keymap for the current line. Default to true.
  ---                                     Note that avante will safely set these keymap. See https://github.com/yetone/avante.nvim/wiki#keymaps-and-api-i-guess for more details.
  ---3. auto_set_highlight_group        : Whether to automatically set the highlight group for the current line. Default to true.
  ---4. support_paste_from_clipboard    : Whether to support pasting image from clipboard. This will be determined automatically based whether img-clip is available or not.
  ---5. minimize_diff                   : Whether to remove unchanged lines when applying a code block
