Copy, paste, run. If you get JSON back with a message, you're good.

After Submit, open the model picker and confirm the relay models are listed, then send one short prompt in a new Kilo task.

Gotchas

• !Kilo auto-fetches models from the provider's /v1/models endpoint; if that call fails you must type model IDs manually, which is not a fatal error.
• !The docs' only Base URL example is OpenAI-style (https://api.your-provider.com/v1), which is why people paste /v1 into the Anthropic Messages field too. For Anthropic Messages the value is the bare host; Kilo also accepts a full endpoint (.../v1/messages) if you prefer being explicit.
• !Auto-fetch must point at https://api.llmrelay.dev/v1. Tested 2026-07-28: the /v1-less https://api.llmrelay.dev/models returns 200 with our marketing HTML page, not JSON — so a wrong base URL here fails as an unparseable model list rather than a clean error.
• !Token limits, tool-calling flags and variants are not exposed in the dialog; edit kilo.jsonc directly for those.
