bug: using gemini provider with GEMINI_API_KEY environment defaults to claude

[k8s-1]

Describe the bug

• using gemini provider with GEMINI_API_KEY environment variable defaults to claude
• e.g. AvanteAsk will prompt for a claude API key and will show that claude is being used (top right)

To reproduce

lazyvim config:

return {
  "yetone/avante.nvim",
  event = "VeryLazy",
  lazy = false,
  version = false, -- set this if you want to always pull the latest change
  opts = {
    -- add any opts here
  },
  provider = "gemini",
  behaviour = {
    auto_suggestions = false, -- Experimental stage
  },
  -- if you want to build from source then do `make BUILD_FROM_SOURCE=true`
  build = "make",
  dependencies = {
    "stevearc/dressing.nvim",
    "nvim-lua/plenary.nvim",
    "MunifTanjim/nui.nvim",
    {
      -- Make sure to set this up properly if you have lazy=true
      'MeanderingProgrammer/render-markdown.nvim',
      opts = {
        file_types = { "markdown", "Avante" },
      },
      ft = { "markdown", "Avante" },
    },
  },
}

Expected behavior

• having provider = "gemini" and GEMINI_API_KEY uses the gemini API

Environment

          },
          ft = { "markdown", "Avante" },
        },
      },
    }
  },
})

Currently working around it by adding this to config:

  -- Custom hack to force gemini to load instead of claude
  -- 2024-09-13
  init = function()
    vim.api.nvim_create_autocmd("VimEnter", {
      callback = function()
        -- Ensure Avante.nvim has been loaded before switching providers
        if vim.fn.exists(":AvanteSwitchProvider") == 2 then
          vim.cmd("AvanteSwitchProvider gemini")
        end
      end,
    })
  end,

@k8s-1 I am using gemini as my LLM and was able to get it working with the following settings. I think you need to add a gemini section to your config and select the model to make it work.

gemini = {
    -- @see https://ai.google.dev/gemini-api/docs/models/gemini
    model = "gemini-1.5-pro-exp-0827",
    -- model = "gemini-1.5-flash",
    temperature = 0,
    max_tokens = 4096,
  },

This is my whole setup for Avante in case it helps.

local M = {
  "yetone/avante.nvim",
  event = "VeryLazy",
  lazy = false,
  version = false, -- set this if you want to always pull the latest change
  -- if you want to build from source then do `make BUILD_FROM_SOURCE=true`
  build = "make",
  dependencies = {
    "stevearc/dressing.nvim",
    "nvim-lua/plenary.nvim",
    "MunifTanjim/nui.nvim",
    --- The below dependencies are optional,
    "echasnovski/mini.icons", -- or "nvim-tree/nvim-web-devicons"
    {
      -- support for image pasting
      "HakonHarnes/img-clip.nvim",
      event = "VeryLazy",
      opts = {
        -- recommended settings
        default = {
          embed_image_as_base64 = false,
          prompt_for_file_name = false,
          drag_and_drop = {
            insert_mode = true,
          },
          -- required for Windows users
          use_absolute_path = true,
        },
      },
    },
    {
      -- Make sure to set this up properly if you have lazy=true
      "MeanderingProgrammer/render-markdown.nvim",
      opts = {
        file_types = { "markdown", "Avante" },
      },
      ft = { "markdown", "Avante" },
    },
  },
}

M.opts = {
  provider = "gemini", -- Recommend using Claude
  -- auto_suggestions_provider = "copilot", -- Since auto-suggestions are a high-frequency operation and therefore expensive, it is recommended to specify an inexpensive provider or even a free provider: copilot
  behaviour = {
    auto_suggestions = false, -- Experimental stage
    auto_set_highlight_group = true,
    auto_set_keymaps = true,
    auto_apply_diff_after_generation = false,
    support_paste_from_clipboard = false,
  },
  gemini = {
    -- @see https://ai.google.dev/gemini-api/docs/models/gemini
    model = "gemini-1.5-pro-exp-0827",
    -- model = "gemini-1.5-flash",
    temperature = 0,
    max_tokens = 4096,
  },
}
