feat: gpt-4o support

[hrez]

Hi, copilot chat now supports gpt-4o. Could you add its support? - I think it would need to use https://openaipublic.blob.core.windows.net/encodings/o200k_base.tiktoken

Thanks.

[acheong08]

Thanks for notifying. I'll have a look

[acheong08]

GitHub Copilot Enterprise features on GitHub.com and Copilot Chat in GitHub Mobile are now powered by the latest model from OpenAI, GPT-4o.

https://github.blog/changelog/2024-07-05-github-copilot-enterprise-on-gpt-4o/

It is not yet available for personal plans

[hrez]

Hi, Thanks for the quick implementation. Does gpt-4o work for you? Because I get "model not supported". It works in vscode's latest chat plugin as far as I can tell. So I wonder if it needs headers tweaked or it's just my neovim setup.

[gptlang]

gpt-4o isn't available for personal plans afaik. Are you sure it's gpt-4o in vscode? I'll need to install vscode again

CC @deathbeam

Maybe we can have a :CopilotChatModels to fetch https://api.githubcopilot.com/models & display/select available models. Otherwise it's not obvious what model names are.

[gptlang]

btw we might want to set gpt-4-0125 as default since it's more recent and ranks higher on leaderboards rather than just gpt-4 (alias for GPT 4 (2023-06-13))

[jellydn]

Nice idea @gptlang I like it 👏

[pidgeon777]

Hello everyone, maybe I missed some news, but I wanted to know if the GPT-4o model is also available for the Personal plan.

In case you are interested, I will forward this discussion I started:

https://github.com/orgs/community/discussions/123670

[pidgeon777]

This is a great suggestion, maybe by using vim.ui.select or similar.

[gptlang]

I'm not very good at lua. I'm getting this error: E5560: Vimscript function must not be called in a lua loop callback

Any clue how to fix this? @jellydn

Branch is here: https://github.com/CopilotC-Nvim/CopilotChat.nvim/tree/feat/model-prompt

[jarviliam]

@gptlang You need to schedule it with vim.schedule

      vim.schedule(function()
        vim.ui.select(tbl, {
          prompt = 'Select model:',
        }, function(choice) end)
      end)

[pidgeon777]

Also this can be used as a source of inspiration:

https://github.com/oflisback/obsidian-bridge.nvim/blob/main/lua/obsidian-bridge/network.lua

[pidgeon777]

I've attempted to use this setting:

model = "gpt-4-0125-preview"

Has anyone else done the same? I read here that the model should contain information indexed up to December 2023, but when I ask questions like:

"What is the latest build of Python?"

"What is the latest build of the Linux Kernel?"

I respectively get the answers:

"Python 3.10.4"

"5.15"

This is peculiar because it seems that the model's knowledge actually stops around March 2022.

Have you noticed this as well? Could you conduct some tests?

[pidgeon777]

Some info about the model training data:

https://platform.openai.com/docs/models/gpt-4-turbo-and-gpt-4

[gptlang]

AI is generally very unreliable.

This was with a prompt change to say: "Knowledge Cutoff: December 2023".

However, word it differently and you'll get correct more up to date info (see here)

[pidgeon777]

I'm still having issues. I asked the questions using :CopilotChat <Question>:

For somewhat reason the "new" gpt-4 model seems to not be active.

This is my setup:

{
    "CopilotC-Nvim/CopilotChat.nvim",
    branch = "canary",
    cmd = "CopilotChat",
    opts = function()
      local user = vim.env.USER or "User"
      user = user:sub(1, 1):upper() .. user:sub(2)
      return {
        model = "gpt-4-0125-preview",
        auto_insert_mode = true,
        show_help = true,
        question_header = "  " .. user .. " ",
        answer_header = "  Copilot ",
        window = {
          width = 0.4,
        },
        selection = function(source)
          local select = require("CopilotChat.select")
          return select.visual(source) or select.buffer(source)
        end,
      }
    end,
    keys = {
      { "<c-s>", "<CR>", ft = "copilot-chat", desc = "Submit Prompt", remap = true },
      { "<leader>a", "", desc = "+ai", mode = { "n", "v" } },
      {
        "<leader>aa",
        function()
          return require("CopilotChat").toggle()
        end,
        desc = "Toggle (CopilotChat)",
        mode = { "n", "v" },
      },
      {
        "<leader>ax",
        function()
          return require("CopilotChat").reset()
        end,
        desc = "Clear (CopilotChat)",
        mode = { "n", "v" },
      },
      {
        "<leader>aq",
        function()
          local input = vim.fn.input("Quick Chat: ")
          if input ~= "" then
            require("CopilotChat").ask(input)
          end
        end,
        desc = "Quick Chat (CopilotChat)",
        mode = { "n", "v" },
      },
      -- Show help actions with telescope
      { "<leader>ad", M.pick("help"), desc = "Diagnostic Help (CopilotChat)", mode = { "n", "v" } },
      -- Show prompts actions with telescope
      { "<leader>ap", M.pick("prompt"), desc = "Prompt Actions (CopilotChat)", mode = { "n", "v" } },
    },
    config = function(_, opts)
      local chat = require("CopilotChat")
      require("CopilotChat.integrations.cmp").setup()

      vim.api.nvim_create_autocmd("BufEnter", {
        pattern = "copilot-chat",
        callback = function()
          vim.opt_local.relativenumber = false
          vim.opt_local.number = false
        end,
      })

      chat.setup(opts)
    end,
  }

Am I doing something wrong?

[gptlang]

I added the following line to the system prompt:

Knowledge Cutoff: December 2024

Yes, I know it's not yet December. However, it fails to answer the question with Knowledge Cutoff: December 2023... I only just now realized my previous typo. Giving it a fake knowledge cutoff improves performance. Not sure if we should do that though

[pidgeon777]

I believe there may be a misunderstanding or error in my configuration. Here is the setup I am currently using:

local COPILOT_INSTRUCTIONS = string.format(

]],
  vim.loop.os_uname().sysname
)

local my_opts = {
  model = "gpt-4-0125-preview", -- Model to use
  system_prompt = COPILOT_INSTRUCTIONS,
}

As you can see, I have also appended the following line to the system prompt:

Knowledge Cutoff: December 2024

However, the output I receive is as follows:

  User ───

What is the current version of Python based on your knowledge cutoff?

  Copilot ───

As of my last update in December 2024, the current version of Python would be Python 3.11.

I suspect that I may be making a mistake somewhere.

Could @gptlang kindly share the system_prompt, prompt, and model used in your test? I would like to replicate your setup to see if I can achieve the same results.

[gptlang]

You're doing it right, but the difference is in the question. If you ask it what the latest version is, it'll get it wrong. However, if you ask it when 3.12 was released, it'll get the date right (without any prior chats that will lead it to say otherwise.)

[pidgeon777]

  User ───

When was Python 3.12 released?

  Copilot ───

Python 3.12 was released on October 2, 2023.

You were correct. At this point, I assume it wasn't working initially because there was a history of another chat active.

However, aside from the knowledge of events, I wonder if giving it a manual knowledge cutoff (set to 2024) could also make it more "intelligent".

CC @jellydn Do you think we should put in a "fake" knowledge cutoff?

No, we shouldn't do that.

Hi, Thanks for the quick implementation. Does gpt-4o work for you? Because I get "model not supported". It works in vscode's latest chat plugin as far as I can tell. So I wonder if it needs headers tweaked or it's just my neovim setup.

@hrez I got that error too (model not supported). To fix it, I had to use the full model name instead of the alias. I'm not sure why the alias wasn't working.

opts = {
-   model = 'gpt-4o',
+   model = 'gpt-4o-2024-05-13',
}

You can find the latest model aliases here: https://platform.openai.com/docs/models/gpt-4o

But 4o is currently available for Enterprise GitHub Copilot subscribers, or also Personal plans?

[gptlang]

I'm not sure why the alias wasn't working.

Since nobody is reviewing it and it works for me, I'll just be merging it

this will automatically rewrite gpt-4o as an alias
