Avante.nvim

A Neovim agent. Settings are lua, provider openai.

Three fields. Copy, don’t type

require('avante').setup({
  provider = 'openai',
  openai = {
    endpoint = 'https://cheapai.lol/v1',
    model = 'claude-opus-4.8',
    api_key = 'sk-…',
  },
})

Do it in order. Don’t skip

1. Install Avante with your Neovim plugin manager, as their README says.

2. In the plugin config set provider = 'openai'.

3. In the openai block set endpoint = 'https://cheapai.lol/v1', model = 'claude-opus-4.8' and api_key to your key.

4. You can leave the key out of the file and set OPENAI_API_KEY instead.

5. Restart Neovim, open Avante and type “hi”.

Check

If it didn’t start

• “401 / unauthorized / invalid api key” — the key was not copied whole. It starts with sk- and has no space at either end.
• “model not found” / “named models unavailable” / model in red — the name must match exactly: claude-opus-4.8. Not “Opus 5”, not opus, not claude-3, not gpt-4.
• The app shows no models — reopen its settings page: the model list is served from our address and appears once the Base URL and key are right.
• “Connection error” / spinner and silence — wrong Base URL. Almost every app wants the address with a /v1 tail.
• “/v1/v1” in the error — the app appends /v1 itself. Drop the tail, leave the site address.
• It replied, then stopped — you ran out of tokens. The balance is in your dashboard. Topping up on FunPay from the same nick lands on the same key.
