Kilo Code with UberLLM: add a custom provider in 1 minute

Kilo Code's current version (7.x) shares one settings file between VS Code, JetBrains and the kilo CLI, so you set UberLLM up once. Older guides that show a provider dropdown with model-info fields describe the legacy extension.

Steps (in the editor)

1. Make a key on your keys page and add credit.
2. Open Kilo Code, click the gear icon → Providers tab, scroll to the bottom and click Custom provider.
3. Fill in:
   • Provider ID: uberllm
   • Display name: UberLLM
   • Provider API: OpenAI Compatible
   • Base URL: https://api.uberllm.dev/v1
   • API key: your ull_… key
4. Press Fetch models. The list comes from UberLLM; keep the ones you want, for example moonshotai/kimi-k3.
5. Click Submit, then choose the model in Kilo's model picker.

Steps (config file)

The same provider in ~/.config/kilo/kilo.jsonc (Windows: C:\Users\<you>\.config\kilo\kilo.jsonc; for one project, .kilo/kilo.jsonc in the project):

{
  "provider": {
    "uberllm": {
      "npm": "@ai-sdk/openai-compatible",
      "name": "UberLLM",
      "env": ["UBERLLM_API_KEY"],
      "options": { "baseURL": "https://api.uberllm.dev/v1" },
      "models": {
        "moonshotai/kimi-k3": {
          "name": "moonshotai/kimi-k3",
          "tool_call": true,
          "limit": { "context": 200000, "output": 32000 }
        }
      }
    }
  },
  "model": "uberllm/moonshotai/kimi-k3"
}

Then set UBERLLM_API_KEY=ull_your_key in your environment. The limit numbers are an example: copy the real context length from the model's page on uberllm.dev/models.

Two settings people miss

• limit: without it Kilo treats the context as 0 and never compacts a long task, so it eventually fails. The editor dialog cannot set it; add it in the file ("edit advanced settings in the JSON config file").
• tool_call: true: Kilo's agent works through tools. If the model answers in plain text instead of editing files, this is missing.

Prefer the Anthropic format?

Kilo also offers Provider API → Anthropic Messages. With UberLLM, use https://api.uberllm.dev/v1 as the Base URL there as well (not the bare host), and the same key. Model fetching is not available in that mode, so type the ids yourself.

Troubleshooting

• "Authentication failed. Check the API key above and try again." when fetching: the key is missing or has a space.
• Model not in the picker: the model key must match uberllm/<model id>. Run kilo models to see what Kilo loaded.
• Agent never edits files: add "tool_call": true to the model.
• Task fails after a long session: set limit.context.
• 402 insufficient credits: add credit on the credits page.
